VENDOR COMPLIANCE TO STATE LAW The 1985 Session of the Texas Legislature passed House Bill 620 relative to the award of contracts to nonresident bidders . This law provides that, in order to be awarded a contract as low bidder, nonresident bidders (out-of-state contractors whose corporate offices or principal place of business are outside of the State of Texas) bid projects for construction , improvements, supplies or services in Texas at an amount lower than the lowest Texas resident bidder by the same amount that a Texas resident bidder would be required too underbid a nonresident bidder in order to obtain a comparable contract in the State in which the nonresident's principal place of business is located. The appropriate blanks in Section A must be filled out by all out-of-state or nonresident bidders in order for your bid to meet specifications. The failure of out-of-state or nonresident contractors to do so will automatically disqualify that bidder. Resident bidders must check the box in Section B. A. Nonresident vendors in (give State), our principal place of business, are required to be percent lower than resident bidders by State law. A copy of the Statute is attached . Nonresident vendors in (give State), our principal place of business, are not required to underbid resident bidders. B.

Based upon the City's assessment of the submitted information, a recommendation regarding the award of a contract will be made to the City Council. Failure to submit the additional information if requested may be grounds for rejecting the apparent low bidder as non-responsive . Affected contractors will be notified in writing of a recommendation to the City Council. D-70 EARLY WARNING SYSTEM FOR CONSTRUCTION Time is of the essence in the completion of this contract. In order to insure that the contractor is responsive when notified of unsatisfactory performance and/or of failure to maintain the contract schedule, the following process shall be applicable: The work progress on all construction projects will be closely monitored. On a bi-monthly basis the percentage of work completed will be compared to the percentage of time charged to the contract. If the amount of work performed by the contractor is less than the percentage of time allowed by 20% or more (example: 10% of the work completed in 30% of the stated contract time as may be amended by change order), the following proactive measures will be taken: 1. A letter will be mailed to the contractor by certified mail, return receipt requested demanding that, within 10 days from the date that the letter is received, it provide sufficient equipment, materials and labor to ensure completion of the work within the contract time. In the event the contractor receives such a letter, the contractor shall provide to the City an updated schedule showing how the project will be completed within the contract time. 2 . The Project Manager and the Directors of Water Department, and Department of Transportation and Public Works will be made aware of the situation . If necessary, the City Manager's Office and the appropriate city council members may also be informed . 3. Any notice that may, in the City's sole discretion, be required to be provided to interested individuals will distributed by the Water Department's Public Information Officer. 4. Upon receipt of the contractor's response, the appropriate City departments and directors will be notified. The Water Department's Public Information Officer will, if necessary, then forward updated notices to the interested individuals. 5. If the contractor fails to provide an acceptable schedule or fails to perform satisfactorily a second time prior to the completion of the contract, the bonding company will be notified appropriately. 0210912010 SC-57 PART D -SPECIAL CONDITIONS 0-71 AIR POLLUTION WATCH DAYS The Contractor shall be required to observe the following guidelines relating to working on City construction sites on days designated as "AIR POLLUTION WATCH DAYS". Typically, the OZONE SEASON, within the Metroplex area, runs from May 1, through OCTOBER 31, with 6:00 a.m. -10:00 a.m. being critical BECAUSE EMISSIONS FROM THIS TIME PERIOD HAVE ENOUGH TIME TO BAKE IN THE HOT ATMOSPHERE THAT LEADS TO EARLY AFTERNOON OZONE FORMATION .. The Texas Commission on Environmental Quality (TCEQ), in coordination with the National Weather Service, will issue the Air Pollution Watch by 3:00 p .m. on the afternoon prior to the WATCH day. On designated Air Pollution Watch Days, the Contractor shall bear the responsibility of being aware that such days have been designated Air Pollution Watch Days and as such shall not begin work until 10:00 a.m. whenever construction phasing requires the use of motorized equipment for periods in excess of 1 hour. However, the Contractor may begin work prior to 10:00 a.m. if use of motorized equipment is less than 1 hour, or if equipment is new and certified by EPA as "Low Emitting", or equipment burns Ultra Low Sulfur Diesel (ULSD), diesel emulsions, or alternative fuels such as CNG. If the Contractor is unable to perform continuous work for a period of at least seven hours between the hours of 7:00 a.m. -6:00 p.m., on a designated Air Pollution Watch Day, that day will be considered as a weather day and added onto the allowable weather days of a given month. 0-72 FEE FOR STREET USE PERMITS AND RE-INSPECTIONS Contractor is required to secure a Street Use Permit, issued by the City of Fort Worth Transportation and Public Works Permit Center (817-392-6594) prior to any work in public right of way. Permit will not be issued without a traffic control plan sealed and signed by a registered professional engineer licensed to practice in the State of Texas. Failure to acquire the proper permit and permission may result in a fine of $500/day to the contractor performing the work. Payment by the contractor for all Street Use Permits shall be considered subsidiary to the contract cost and no additional compensation shall be made .

The certification shall be furnished to the owner prior to proceeding to furnish soils to the site . The City shall also require the contractor to provide the services of an EPA approved laboratory to perform , as a minimum, a toxic contaminant scan of composite soil samples representative of each separate proposed borrow source, in accordance with EPA protocol for the list of contaminants contained in 40 CFR , Part 261 , Appendix VIII , by EPA methods SW-846, prior to importing the soil borrow. Any potential off-site soil borrow on which the test results indicate the presence of contaminants above background levels shall be rejected. Soil materials derived from the excavation of underground petroleum storage tanks shall not be used as fill. 3.00 EXECUTION STS-003-4 - . J j 3.01 CLEARING, GRUBBING, AND STRIPPING All areas to be excavated or to receive earth fill, pavements, structures, or other such facilities , shall be cleared, grubbed, and stripped prior to excavation and subgrade preparation . Clearing and grubbing shall consist of the removal of all trees , large vegetation, abandoned structures , and debris, including all roots 1 inch or larger in diameter, to a minimum depth of 18 inches below the proposed subgrade level. Stripping shall consist of the removal of all topsoil, roots, vegetation and rubbish not removed by the clearing and grubbing operation. Additionally, any other unsatisfactory material shall be removed from the subgrade area of future compacted fills or embankments, and from the surfaces underneath future roadways and related structures. The stripped areas shall be observed to determine if additional excavation is required to remove weak or otherwise unsuitable materials that would adversely affect the fill placement. 3.02 EXCAVATION Excavations shall be made to the true lines and grades necessary for construction of the roadway facilities. If solid rock excavation in open cut areas or trenches is defined as an additional pay item in the construction documents, the following definition of "solid rock" shall apply: In order for any rock material to be considered as solid rock, it must meet all of the following criteria : • The rock must be massive and in a continuous layer at least 2 feet thick. • The rock must have an unconfined compressive strength greater than 80 ksf. • The rock cannot be ripped from a starter trench in an open cut excavation with a D-9 Caterpillar (or equivalent) bull dozer with a single tooth ripper, or in a trench excavation with a 235C Caterpillar (or equivalent) track hoe excavator equipped with a nominal 30- inch wide extreme-service trenching bucket with front and rear mounted rock ripper teeth . Boulders and cobbles, whether in densely spaced layers or occasional occurrence, shall not be classified as solid rock, regardless of the hardness of the individual boulders or cobbles. STS-003-5 In general , excavation slopes of 1-horizontal to 1-vertical are adequate for temporary slop es during construction . However, some soil conditions will become unstable where a 1-horizontal to 1-vertical slope is used. These unstable soils include, but are not necessarily limited to (1) jointed , fissured , soft, and slickensided clays , (2) soils with pockets or layers of sand or gravel , and (3) soils with ground -water seepage occurring . Slopes in these types of soils may become unstable during periods of wet weather or as loads are applied to the top and/or along the slope . Weather conditions , the excavation depth , adjacent structures , construct ion equipment, and the length of time the excavation will remain open also affect the stability of slopes. Temporary slopes of 2-horizontal to 1-vertical and flatter would be more appropriate for this these conditions, for slopes above the ground -water table . Soils below the ground-water table and saturated soils , including but not necessarily limited to saturated sands , will require very flat slopes or shoring to remain stable during construction . In all cases , the contractor must follow the requirements of the Occupational Safety and Health Administration (OSHA). It is important for the contractor to monitor the slope stab ility by observation and measurement, and to prevent ex cessive loads (especially heavy vibratory loads) from being applied to the slope. The contractor shall be responsible for maintaining the slopes in a safe condition during construction and the use of slope stability monitoring equipm ent is recommended for all critical slopes . Th is manual has not been prepared for trench safety and/or excavation slope design . The responsibility for trench safety and/or excavation slope design shall be the Contractor's responsibility . The side slopes of excavations through the overburden soils shall be made in such a manner to provide for their stability during construction. Structures, pipelines or other facilities which are constructed prior to or during the currently proposed construction and which require excavation, shall be protected from loss of end bearing or lateral support. Temporary construction slopes and/or permanent embankment slopes shall be protected from surface runoff water. Site grading shall be designed to allow drainage at planned areas where erosion protection is provided, instead of allowing surface water to flow down unprotected slopes . STS-003-6 - Trench safety recommendations are beyond the scope of this study. The contractor must comply with all applicable safety regulations concerning trench safety and excavations, including, but not limited to OSHA regulations . The construction documents shall include a specific bid item for trench safety systems . 3.04 DEWATERING OF EXCAVATIONS The design or quantitative analyses of ground-water dewatering systems is beyond the scope of this manual. The following information is provided as a guideline only . The contractor shall be responsible for selecting and providing appropriate excavation dewatering systems for use during construction. Ground water will likely be encountered within some excavations during wet seasons and during wet years, and if excavation depths are near or below the ground water table, including perched water tables . The amount of ground water encountered is dependent on the depth of the excavations, the time left open, weather conditions, water levels in adjacent surface water bodies, and adjacent activities. The decision as to the method for handling ground water depends upon such factors as the soil characteristics within the excavation depth, site hydrogeology, the size and depth of the excavation, method of excavation and side slopes, the proximity of existing structures, their depth and foundation type, and the design and function of the specific roadway facilities. Choice of a particular method or a combination of methods for dewatering any given excavation will require an analysis by the contractor of the subsurface soil and ground-water conditions, the requirements of the work, and the contractor's experience with dewatering excavations . Although a geotechnical study may have been made for the City, the scope of the study was for design purposes and did not include an evaluation of construction dewatering requirements; therefore some unanticipated subsurface conditions could exist related to construction dewatering . Regardless of the dewatering method selected, it shall be capable of lowering and continuously maintaining the ground-water surface a minimum of 3 feet below the base of all excavations throughout the construction period. The contractor shall be required to provide STS-003-7 adequate personnel and equipment to operate and maintain the dewatering system on a 24 - hour basis , as required . The dewatering method selected by the contractor must be designed to prevent settlement or other adverse affects to adjace nt pavemen t s or structures due to drawdown of ground water, or otherwise. Th is may require isolation of the dewatering areas with sheet pile cutoffs or similar facilities . The contractor shall be required to demonstrate in appropriate submittals that the proposed method of dewatering will not adversely affect adjacent pavements or structures , prior to beginning dewatering operations. 3.05 SUBGRADE PREPARATION The subgrade shall be firm and able to support the construction equipment without displacement. Soft or yielding subgrade shall be corrected and made stable before construction proceeds. The subgrade shall be proof rolled to detect soft spots, which if exist, shall be reworked . Proof rolling shall be performed using a heavy pneumatic t ired roller, loaded dump truck , or similar equipment weighing approximately 25 tons . The equipment shall be driven slowly over the subgrade with the tires staggered approximately 3 feet on each successive pass to allow detection of any soft or pumping subgrade areas . The proof rolling operations shall be observed by the proj ect geotechnical engineer. The sides of stump holes or other similar caviti es or depressions shall be broken down to flatten the slopes (no steeper than 5 horizontal to 1 vertical), with the sides of the cuts or holes being scarified to provide bond between the foundation soils and the embankment fill. Each depression or hole shall be filled with the same type of material that is adjacent to the depression , unless such material is unsuitable for fill, in which case General Earth Fill shall be used . Existing hillsides or slopes that will rece ive fill shall be loosened by scarifying or plowing to a depth of not less than 8 inches. The fill material shall be benched into the existing slope in such a manner as to provide adequate bonding between the fill and slope, as well as to allow the fill to be placed in essentially horizontal lifts . Prior to placement of compacted fill in any section of the embankment, after depressions and holes have been filled , the foundation of such sections shall be compacted to the same density and moisture requirement as the embankment. STS -003-8 - - In areas of the subgrade that are too soft, wet or otherwise unstable to allow embankment construction to begin, the use of plating and/or plating in combination with a geogrid may be required . The traffic of heavy equipment, including heavy compaction equipment, may create pumping and general deterioration of the shallower clay soils . Therefore, it shall be anticipated that some construction difficulties will be encountered during periods when these soils are saturated . Often the shallow sandy and silty soils also become wet and pump during rainy months, or due to ground-water conditions . Occasionally clayey, sandy, and silty soils have to be excavated, mixed and dried, and replaced. At times, excavating and replacing with selected soils, the use of lime or cement treatment, or the use of geosynthetics is required before an adequate subgrade can be achieved . 3.06 PLACING OF MATERIAL Embankment materials shall be placed on a properly prepared subgrade as recommended above. The combined excavation, placing, and spreading operation shall be done in such a manner to obtain blending of material, and to provide that the materials, when compacted in the embankment, will have the most practicable degree of compaction and stability. Materials excavated from cut sections or borrow areas and hauled to construct fills shall be mixed and not segregated within any specific fill zone. However, selective excavation and segregation will be necessary to meet required specifications for the various fill zones. The intent is to produce the highest practicable degree of homogeneity within any specified earth-fill zone. If the surface of the embankment is too smooth and hard to bond properly with a succeeding layer, the surface shall be roughened and loosened by disking before the succeeding layer is placed. Where fill is to be placed next to existing fill, that fill shall be removed to unweathered, dense material. Each layer shall be benched and disked as adjoining lifts are placed . Material hauling equipment shall be so routed over the embankment surface to distribute the added compaction afforded by the rolling equipment, and to prevent the formation of ruts on the embankment surface. STS-003-9 The surface of the fill shall be graded to drain freely and maintained throughout construction . During the dumping and spreading process , all roots and debris and all rocks greater than 2 inches in maximum dimension shall be removed from the embankment materials . No rocks shall be allowed within the final 8 inch es of subgrade . 3.07 PROCESS ING AND MOISTURE-DENSITY CONTROL Following the spreading and mixing of the soil on the embankment, it shall be processed by disking or pulverizing throughout its thickness to break up and reduce clod size, and provide additional blending of materials . Processing shall consist of at least five passes of a fully penetrating disk plow or three passes of a fully penetrating rota -till pulverizer mixer. Additional passes of the processing equipment shall be performed as necessary to accomplish breaking up , reduction of clod size , moisture conditioning, and blending the fill. Each successive pass of the processing equipment shall be in a direction perpendicular to the previous pass, where working space permits . The maximum loose lift thickness prior to compaction shall be 8 inches. The moisture content of the soil shall be adjusted , if necessary, by either aeration or the addition of water to bring the moisture content within the recommended range . Water required for sprinkling to bring the fill material to the proper moisture conte nt shall be applied evenly through each layer. Water for soil conditioning shall be potable water unless approved otherwise in advance by the Engineer. Any layers that become damaged by weather conditions shall be reprocessed to meet specified requ irements . The compacted surface of a layer of fill shall be lightly loosened by disking before the succeeding layer is placed. When the moisture content and the condition of the fill layer are satisfactory, compaction shall be performed with a heavy tamping foot roller with fully penetrating feet (feet long enough to penetrate into the previous lift) either towed by a crawler-type tractor or the self-propelled type . The tamping foot roller shall weigh no less than 2,000 pounds per linear foot of drum width . Vibratory tamping rollers shall be used for compacting sand ier fill materials. The in-place density of the fill shall be no less than 95 percent of the maximum dry density as determined by ASTM D 698, Standard Proctor, at a moisture content between optimum and 5 percentage points wet of optimum moisture content for any low-permeability earth fill zones STS-003-10 -- - • f and between 2 percentage points below to 5 percentage points above optimum moisture content for non-expansive earth fill zones, general earth fill zones, and common earth fill zones , with the exception that the top 8 inches of the soil subgrade for pavement areas shall be compacted to a minimum of 100 percent of the maximum dry density as determined by ASTM D 698, Standard Proctor, at a moisture content between 2 percentage points below to 3 percentage points wet of optimum moisture content. The moisture content and density of all fill material shall be maintained at the specified range of moisture and density. These moisture ranges represent the maximum allowable limits. It is possible unde~ some circumstances or with some soils , that a more narrow range, within the required limits, will be necessary for the contractor to consistently achieve the specified density . In order to help provide a homogeneous earth fill mass , a minimum of eight passes of the tamping foot roller shall be provided, even if density tests indicate that the specified density is achieved with fewer passes. Field density tests (including moisture content) shall be taken as each lift of fill material is placed. A minimum of one field density test per lift for each 2500 square feet of compacted area shall be performed. For small or critical areas, the frequency of testing shall be reduced to one test per 1000 square feet or less. A minimum of two density tests shall be taken on each lift, regardless of size. The earthwork operations shall be observed and tested on a cont inuing basis by an experienced soil technician working in conjunction with the project geotechnical engineer. Each lift shall be compacted, tested, and approved before another lift is added. The purpose of the field density tests is to provide some indication that uniform and adequate compaction is being obtained . The actual quality of the fill, as compacted, shall be the responsibility of the contractor and satisfactory results from the tests shall not be considered as a guarantee of the quality of the contractor's filling operations . 3.08 STRUCTURE BACKFILL PLACEMENT AND COMPACTION The backfill material shall be placed in maximum 8-inch lifts and compacted to a density ranging between 95 and 100 percent of maximum Standard Proctor (ASTM D 698) dry density at a moisture content ranging from 2 percentage points below optimum to 5 percentage points STS-003-11 above optimum for the backfill materials . Caution shall be exercised not to over-compact the backfill. Over-compaction will result in excessive lateral earth pressures on structures . Hand-operated tampers or other lightweight compactors shall be used in the 5-foot area adjacent to structures . Non-expansive earth fill shall be used for structure backfill, unless specifically stated otherwise elsewhere in the contract documents. The lift thickness shall be reduced to 4 inches for those areas where hand-operated compactors are required. The backfill surface shall slope away from the structures on a gradient of 1.5 to 3 percent, such that surface water does not pond adjacent to the structure within the backfill zone . Topsoil and seeding shall be accomplished to help prevent drying and cracking of the backfill surface. The slope shall be maintained on a 1.5 to 3 percent gradient after topsoil is placed . 3.09 TRENCH BACKFILL Trench backfill for pipelines or other utilities shall be properly placed and compacted. Overly dense or dry backfill can swell and create a mound along the completed trench line. Loose or wet backfill can settle and form a depression along the completed trench line . Distress to overlying structures, pavements , etc. is likely if heaving or settlement occurs . Non-expansive earth fill or flowable fill shall for trench backfill in all areas adjacent to structures. Care shall be taken not to use free draining granular material, to prevent the backfilled trench from becoming a French drain, which might allow intrusion of surface or subsurface water beneath structures , pipelines , or pavements . If a higher class of bedding material is required for the pipelines near or beneath structures or pavements , flowable fill that will limit water intrusion into the trench and will not require compaction after placement shall be used. The non-expansive earth fill shall be placed in approximate 4-to 6-inch loose lifts . The density and moisture content shall be as required for non-expansive fill in section 3.04 of this specification, except all non- expansive backfill above the spring line of the pipes, in sections of the trench underneath pavements , shall be compacted to a minimum of 100 percent of maximum dry density (ASTM D 698). Class 2 Aggregate fill, as defined in STS-004 AGGREGATE FILL CLASSIFICATIONS may be used for pipelines completely outside the area of structures and pavements or beneath pavements when the top of the aggregate fill zone is a minimum of 10 feet deep below the pavement subgrade . Class 2 Aggregate Fill shall be compacted with a vibratory compactor, to a minimum of 95 percent of Maximum Index Density as determined by ASTM D4253 (or a manual procedure approved by the geotechnical engineer which produces similar results to the ASTM D 4253 procedure), at a moisture content that will facilitate compaction . A minimum of STS-003 -12 one field density test shall be taken per lift for each 150 linear feet of trench, with a minimum of two tests per lift. In restricted areas where compaction of non -expansive earth fill is not practical, flowable fill shall be used . Where flowable fill is used, each lift or section shall be allowed to reach initial set as required to provide the intended support , prior to the next lift or section being placed . This specification does not address trenching, embedment, and backfill for cross-country utilities or pipelines which are not beneath or immediately adjacent to the pavements . 3.10 AGGREGATE FILL PLACEMENT FOR STRUCTURE BACKFILL Aggregate Fill, if specified for any zones of structure backfill, shall be compacted in maximum 6-inch lifts with a steel -wheeled vibratory compactor of sufficient weight to achieve full consolidation of the aggregate fill . Aggregate fill shall be compacted to a minimum of 95 percent of Maximum Index Density as determined by ASTM D 4253 (or a manual procedure approved by the geotechnical engineer which produces similar results to the ASTM D 4253 procedure), at a moisture content that will facilitate consistent compaction . A minimum of 4 passes of the compactor shall be provided , even if density tests indicate that the recommended density is achieved with fewer passes. A hand-operated vibratory plate compactor of the ''walk behind " type shall be used in the 5-foot areas adjacent to structures to reduce potential for damage or excessive pressure on the structure . In areas where the hand-operated vibratory plate compactor is used, the lift thickness shall be reduced to 4-inches . Care shall be taken during compaction of aggregate fill to prevent damage to any geosynthetics used in conjunction with the fill . 3.11 EROSION AND SEDIMENT CONTROL All disturbed areas shall be protected from erosion and sedimentation during construction, and all permanent slopes and other areas subject to erosion or sedimentation shall be provided with permanent erosion and sediment control facilities . All applicable ordinances and codes regarding erosion and sediment control shall be followed . 4.00 MEASUREMENT AND PAYMENT Measurement and payment for EARTHWORK shall be as specified in the contract documents for each specific pavement project.

Storage and Heating of Materials. Do not h eat th e asphalt binder above the temperatures sp ec ifi ed in Item 300, "Asphalts, Oils, and Emulsions" or outside the manufacturer's recommended valu es. On a daily basis, provide the E ng ineer with the records of asphalt binder and hot-mix asphalt discharge tempe ratures in acco rdan ce with Item 320, "E quipm ent for As ph a lt Concrete Pavement." U nl es s oth erwi se approved, do not store mixture for a peri od long enou gh to affect the quality of the mixture, nor in any case lon ger than 12 hr. 3. Mixing and Discharge of Materials. Notify the Engineer of the target discharge temperature and produce the mixture within 25 °F of the target. Monitor the temperature of the material in the truck before shipping to ensure that it does not exceed 350°F . The Department will not pay for or allow placement of any mixture produced at more than 350°F . Control the mixing time and temperature so that substantially all moisture is remo ved from the mixture before discharging from the plant. E. Hauling Operations . Before use, cl ean all truck b eds to ensure mixture is not contaminated. When a releas e age nt is necessary to coat truck beds, use a release agent on the approved li st maintained by the Constructio n Division . F. Placement Operations. Prepare the surface by removing raised pavement markers and obj ectionable material such as moisture, dirt, sand, leaves , and other loose impediments from the surface before placing mixture. Remove vegetation from pavement edges. Place the mixture to meet the typical section requirements and produce a smooth, fini shed surface with a uniform appearance and texture. Offset longitudinal joints of successive courses of hot mix by at least 6 in . Place mixture so longitudinal joints on the surface course coincide with lane lines, or as directed. Ensure that all finished surfaces will drain properly. Place mixture within the compacted lift thickne ss shown in Table 8, unless otherwise shown on the plans or allowed. J Table 8 C ompacte d L"f Th. kn d R I t IC ess an . dC eauire ore H. h CU! t Mu:turc Type Comnacted Lift Thickness Minimum (in.) Maximum (in.)

Measure the roadway su rface temperature with a handheld infrared thermometer. Unless otherwise s hown on the plans, place mixtures only when weather conditi o ns and moisture conditions of the roadway surface are suitable in the opinion of the Engineer. 2. Tack Coat. Clean the surface before placing the tack coat. Unless otherwise approved, apply tack coat uniformly at the rate directed by the Engineer. The Engineer will set the rate between 0 .04 and 0 .10 gal. of residual asphalt per square yard of surface area Apply a thin, uniform tack coat to all contact surfaces of curbs, structures, and all joints. Prev ent splattering of tack coat when placed adjacent to curb, gutter, and structures. Roll the tack coat with a pneumatic-tire roller when directed. The Engineer may use Tex-243-F to verify that the tack coat has adequate adhesive properties. The Engineer may suspend paving operations until there is adequate adhesion. G. Lay-Down Operations. I. Minimum Mixture Placement Temperatures. Use Table 9 for suggested minimum mixture placement temperatures. 2. Windrow Operations. When hot mix is placed in windrows, operate windrow pickup equipment so that substantially all the mixture deposited on th e roadbed is picked up and loaded into the paver. Table 9 s t dM".

Compaction. Use air void control unle ss ordinary compaction control is specified on the plans. Avoid di splacement of the mixture. If displacement occurs, correct to the satisfaction of the Engineer. Ensure pavement is fully compacted before allowing rollers to stand on the pavement. Unless otherwise directed, use only water or an approved release agent on rollers, tamps , and other compaction equipment. Keep diesel, gasoline, oil, grease, and other foreign matter off the mixture . Unless otherwise directed, operate vibratory rollers in static mode when not compacting, when changing directions, or when the plan depth of the pavement mat is less than 1-1/2 in. Use tamps to thoroughly compact the edges of the pavement along curbs, headers, and similar structures and in locations that will not allow thorough compaction with the rollers. The Engineer may require rolling with a trench roller on widened areas, in trenches, and in other limited areas. Allow the compacted pavement to cool to l 60 °F or lower before opening to traffic unless otherwise directed. When directed, sprinkle the finished mat with water or limewater to expedite opening the roadway to traffic. I. Air Void Control. Compact dense-graded hot-mix asphalt to contain from 5% to 9% in-place air voids. Do not increase the asphalt content of the mixture to reduce pavement air voids. a. Rollers. Furnish the type, size, and number or rollers required for compaction, as approved. Use a pneumatic-tire roller to seal the surface, unless otherwise shown on the plans . Use additional rollers as required to remove any roller marks. b. Air Void Determination. Unless otherwise shown on the plans, obtain 2 roadway specimens at each location selected by the Engineer for in-place air void determination. The Engineer will measure air voids in accordance with Tex-207-F and Tex-227-F. Before drying to a constant weight, cores may be predried using a Corelok or similar vacuum device to remove excess moisture. The Engineer will use the average air void content of the 2 cores to calculate the in-place air voids at the selected location. c. Air Voids Out of Range. If the in-place air void content in the compacted mixture is below 5% or greater than 9%, change the production and placement operations to bring the in-place air void content within requirements. The Engineer may suspend production tU1til the in-place air void content is brought to the required level, and may require a test section as described in Section 340.4.H.l.d, "Test Section." d. Test Section. Construct a test section of l lane-width and at most 0.2 mi. in length to demonstrate that compaction to between 5% and 9% in-place air voids can be obtained. Continue this procedure until a test section with 5% to 9% in-place air voids can be produced. The Engineer will allow only 2 test sections per day. When a test section producing satisfactory in-place air void content is placed, resume full production. 2. Ordinary Compaction Control. Furnish the type, size, and number or rollers required for compaction, as approved. Furnish at least l medium pneumatic-tire roller (minimum 12-ton weight). Use the control strip method given in Tex-207-F, Part rv, to establish rolling patterns that achieve maximum compaction. Follow the selected rolling pattern unless changes that affect compaction occur in the mixture or placement conditions. When such changes occur, establish a new rolling pattern. Compact the pavement to meet the requirements of the plans and specifications. When rolling with the 3-wheel, tandem or vibratory rollers, start by first rolling the joint with the adjacent pavement and then continue by rolling longitudinally at the sides. Proceed toward the center of the pavement, overlapping on successive trips by at least l ft., unless otherwise directed. Make alternate trips of the roller slightly different in length. On superelevated curves, begin rolling at the low side and progress toward the high side unless otherwise directed. I. Irregularities. Immediately take corrective action if surface irregularities, including but not limited to segregation, rutting, raveling, flushing, fat spots, mat slippage, color, texture, roller marks, tears, gouges, streaks, or uncoated aggregate particles, are detected. The Engineer may suspend production or placement operations until the problem is corrected. At the expense of the Contractor and to the satisfaction of the Engineer, remove and replace any mixture that does not bond to the existing pavement or that has other surface irregularities identified above. J. Ride Quality. Use Surface Test Type A to evaluate ride quality in accordance with Item 585, "Ride Quality for Pavement Surfaces," unless otherwise shown on the plans. 340.5. Measurement. Hot mix will be measured by the ton of composite hot mix, which includes asphalt, aggregate, and additives. Measure the weight on scales in accordance with Item 520, "Weighing and Measuring Equipment." 340.6. Payment The work performed and materials furnished in accordance with this Item and measured as provided tU1der "Measurement'' will be paid for at the unit price bid for "Dense-Graded Hot-Mix Asphalt (Method)" of the type, surface aggregate classification, and binder specified. These prices are full compensation for surface preparation, materials including tack coat, placement, equipment, labor, tools, and incidentals. Trial batches will not be paid for unless they are incorporated into pavement work approved by the Department. Pay adjustment for ride quality, when required, will be determined in accordance with Item 585, "Ride Quality for Pavement Surfaces."

Do not use rakes or vibrators to distribute concrete. 1. Pavement. Consolidate all concrete by approved mechanical vibrators operated on the front of the paving equipment. Use immersion-type vibrators that simultaneously consolida_te the full width of the placement when machine finishing . Keep vibrators from dislodging reinforcement. Use hand-operated . .I, J vibrators to consolidate concrete in areas not access ible to the machine-mounted vibrators . Do not operate machine-mounted vibrators while the paving equipment is stationary. 2. Temperature Restrictions. Place concrete that is between 40 °F and 95 °F at the time of discharge, except that concrete may be used if it was already in transit when the temperature was found to exceed the a llowable maximum . Take immediate corrective action or cease concrete production when the concrete temperature exceeds 95 °F. Do not place concrete when the ambient temperature in the shade is below 40 °F and falling unless approved. Concrete may be placed when the ambient temperature in the shade is above 35°F and rising or above 40 °F. When temperatures warrant prote ction against fre ez irig , protect the pavement w ith an approved insulating material capable of protecting the concrete for the specified curing period. Submit for approval proposed measures to protect the concrete from anticipated freezing weather for the first 72 hr. after placement. Repair or replace all concrete damaged by freezing. F. Spreading and Finishing. Finish all concrete pavem e nt with approved self- propelled equipment. Use power-driven spread e rs, powe r-driven vibrators , power- driven strike-off, and screed , or approved alternate equ ipment. Use the transverse fin ishing equipment to compact and strike off the concrete to the required section and grade without surface voids. Use float equ ipment for final finishing . Use concrete with a consistency that allows completion of all finishing operations without addition of water to the surface. Use the minimal amount of water fog mist necessary to maintain a moist surface. Reduce fogging if float or straightedge operations result in ex cess slurry. 1. Finished Surface. Perform sufficient checks with long-handled 10-ft. and 15-ft. straightedges on the plastic concrete to ensure that t he final su rface is within the tolerances specified in the contract documents. Check with the straightedge parallel to the centerline. 2. Maintenance of Surface Moisture. Prevent surface drying of the pavement before application of the curing system . Accomplish this by fog applications of evaporation retardant on the pavement surface. Apply evaporation retardant at the rate recommended by the manufacturer. Reapply the evaporation retardant as needed to mainta in the concrete surface in a moist condition until curing system is applied. Do not use evaporation retardant as a finishing aid . 3. Surface Texturing. Perform surface texturing us ing a combination of a carpet drag and metal tining, if required by the contract documents. Complete final texturing before the concrete has attained its initial set. Draw the ·carpet drag longitudinally along the pavement surface with the carpet contact surface area adjusted to provide a satisfactory coarsely textured surface. Operate the metal-tine device to obtain grooves spaced at 1 in ., approximately 3/16 in . deep, with a minimum depth of 1/8 in ., and approximately 1/12 in . wide. Do not overlap a previously tined area . Use manual methods for achieving similar results on ramps and other irregular sections of pavements. Repair damage to the edge of the slab and joints immediately after texturing . Do not tine pavement that will be overlaid . 4. Small or Irregular Placements. Where mach ine placements and finishing of concrete pavement are not practical, use hand equipment and procedures that produce a consolidated and finished pavement se ction to the line and grade . 5. Emergency Procedures. Use hand-operated equipment for applying texture, evaporation retardant, and cure in the event of equipment breakdown. G. Curing. Keep the concrete pavement surface from drying by water fogging until the curing material has been applied . Maintain and promptly repair damage to curing materials on exposed surfaces of concrete pavement continuously for at least 3 curing days. A curing day is defined as a 24 -hr. period when either the temperature taken in the shade away from artificial heat is above 50 °F for at least 19 hr. or when the surface temperature of the concrete is maintained above 40 °F for 24 hr. Curing begins when the concrete curing system has been applied . Stop concrete paving if curing compound is not being applied promptly and maintained adequately. Other methods of curing in accordance with Item 420 , "Concrete Structures," may be used when specified or approved . 1. Membrane Curing. After texturing and immediately after the free surface moisture has disappeared, spray the concrete surface uniformly with 2 coats of membrane curing compound at an individual application rate of not more than 180 sq . ft. per gallon . Apply the first coat within 10 min . after completing texturing operations . Apply the second coat within 30 min. after completing texturing operations. Before and during application, maintain curing compounds in a uniformly agitated condition, free of settlement. Do not thin or dilute the curing compound . Where the coating shows discontinuities or other defects or if rain falls on the newly coated surface before the film has dried enough to resist damage, apply additional compound at the same rate of coverage to correct the damage. Ensure that the curing compound coats the sides of the tining grooves . H. Sawing Joints. Saw joints to the dep t h shown on the plans as soon as sawing can be accomplished without damage to the pavement regardless of time of day or weather conditions . Some minor raveling of the saw cut is acceptable. Use a chalk line, string line, sawing template, or other approved method to provide a true joint alignment. Provide enough saws to match the paving production rate to ensure sawing completion at the earliest possible time to avoid uncontrolled cracking . Reduce paving production if necessary to ensure timely sawing of joints. Promptly restore membrane cure damaged within the first 72 hr. of curing . I. Protection of Pavement and Opening to Traffic. Testing for early opening is the responsibility of the Contractor regardless of job-control testing responsibilities unless otherwise shown in the plans or directed. Testing result interpretation for opening to traffic is subject to the approval of the Engineer. 1. Protection of Pavement. Erect and maintain barricades and other standard and approved devices that will exclude all vehicles and equipment from the newly placed pavement for the periods specified. Before opening to traffic, protect the pavement from damage due to crossings using approved methods. Maintain an adequate supply of sheeting or other material to cover and protect fresh concrete surface from weather damage. Apply as needed to protect the pavement surface from weather. 2. Opening Pavement to Traffic. Before opening to traffic, clean pavement, place stable material against the pavement edges, seal joints , and perform all other traffic safety related work. ,, i .

APPLICATION AND FINAL DETERMINATION OF POLICY It is not the intention of this policy that the Contractor is required to remove and replace at his own expense any concrete that cracks due primarily to causes other than his own materials and/or workmanship . While cracks may be caused by a combination of factors , a primary cause can be determined . It is the policy that if a deficiency of materials and/or workmanship be found to be the primary cause of a crack or cracks, then the contractor shall remove and replace the panels that contain the structural crack or cracks at no expense to the City. If cracks exist in the project , the City Engineer or his/her designee will make the determination if the crack is minor or structural. If the crack is structural , the Contractor and the City will attempt to agree on the cause or causes of the crack . If the Contractor and City agree that the cause of a structural crack requiring removal and replacement is due primarily to Contractor's deficient material or workmanship, the concrete pavement will be removed and replaced at Contractor's entire expense .

A-2 1.1 General GEOTECHNICAL INVESTIGATION STREETPAVEMENTIMPROVMENTS 2007 CRITICAL CAPITAL PROJECT CONTRACT 2007 CO 6A, 68 AND 6C FORT WORTH, TEXAS INTRODUCTION This report presents the results of a geotechnical engineer study for total pavement reconstruction of (9) nine streets in Fort Worth , Texas. More specifically , the designated streets are Glenmont Drive between West Creek Drive and Calousa Drive; Green Avenue between SW Loop 820 and Rutland Avenue ; Odessa Avenue between Wosley Drive and Southgate Drive ; Wharton Drive between Wedgmont Circle and Walton Avenue ; Wonder Drive between Winifred Drive and Walton Avenue ; Indio Street between Fargo Court and SW Dead End; Jenifer Drive between Peggy Drive and Duringer Road ; Natchez Trace between Rockdale Road and Trimble Drive ; and Garrick Avenue between SW Loop 820 and Wooten Drive . This report confirms to the City of Fort Worth Pavement Design Standards Manual , 2005 Edition . 1.2 Purpose and Scope of Work The purpose of this geotechnical engineering study has been to determine the general subsurface conditions , evaluate the engineering characteristics of the subsurface materials encountered , develop recommendations for the types of pavement subgrade preparation and modification . Provide pavement design guidelines and provide earthwork recommendations. To accomplish its intended purposes, the study has been conducted in the following phases : 1) drilling sample borings to determine the general subsurface conditions and to obtain samples for testing; 2) performing laboratory tests on selected samples to determine pertinent engineering properties of the subsurface materials ; and 3) performing engineering analyses, using the field and laboratory data to develop geotechnical recommendations for the proposed construction . It is recommended that Syntec Engineering Group , Inc. be retained to review the construction documents pertaining to the geotechnical recommendations in order to determine that our recommendations have been interpreted as intended. SEG # 0109 -307 Page 2 The scope of the explorations , tests, and analyses for this study , and the recommendations in this report were selected or developed based on our understanding of the project , as described above and in later sections of this report . If pertinent details of the project have changed or otherwise differ from our description , we request that we be notified and engaged to review the changes and to modify our recommendations , if needed . The conclusions and recommendations presented in this report may not apply to different locations at the site. This report should be made available to prospective contractors for information only, and not as a warranty of subsurface conditions . 1.3 Report Format The first sections of the report describe the field and laboratory phases of the study. The remaining sections present our geotechnical recommendations for the design and construction of the new pavement sections . Boring logs and laboratory test results are presented in the report Illustrations . 2.0 FIELD INVESTIGATION AND LABORATORY TESTING 2.1 Field Exploration A total of 9 test borings were drilled and sampled to explore the subsurface conditions at the referenced site. The borings were advanced to a depth of 10 feet or 2 feet into rock, whichever is shallower. The following table summarizes the boring locations: Table 1: Boring Locations Boring Location Boring Location No. No. B-1 Across from 3412 Glenmont Ct. B-2 Across from 5220 Greene Avenue B-3 Across from 5509 Odessa Avenue B-4 Across from 5521 Wharton Drive B-5 Across from 5517 Wonder Drive B-6 Across from 3217 Ind io Street B-7 Across from 5924 Peggy Drive B-8 Across from 328 Natchez Trace SEG # 0109-307 p 3 aQe Boring Location Boring Location No. No . B-9 Across from 5216 Garrick Drive The locations of the borings are shown on Figure 1. Logs of the borings with descriptions of the soils sampled are presented on Figure 2 through 9 . Keys to the terms and symbols used on the boring logs are presented on Figure 10 . The borings were advanced using continuous flight augers and continuous sampling techniques . Undisturbed cohesive soil samples were obtained using 3-inch diameter thin-walled tube samplers that were pushed into the soil. The undrained compressive strength of cohesive soils was estimated in the field using a calibrated pocket penetrometer. Texas Department of Transportation (TxDOT) cone penetration tests were performed in the limestone bedrock . This test consists of driving a 3-inch diameter, 60-degree , steel cone with the energy equivalent of a 170-pound hammer dropped 24 inches . Depending on the resistance of the materials , either the number of hammer blows required to provide 12 inches of penetration or the inches of penetration for 100 blows of the hammer are recorded and are reported on the boring logs at the depths corresponding to where these tests were performed. The borings were drilled using dry auger procedures to observe water levels at the time of the exploration. These water level observations are recorded on the boring logs . 2.2 Laboratory Testing Laboratory tests were performed to define pertinent engineering characteristics of the soils encountered . The laboratory tests included moisture content , dry density determination , visual classification, liquid and plastic limit , unconfined compression, triaxial shear tests, Free Swell tests, Lime series tests and Soluble Sulfate tests . 2.2.1 Classification Tests The results of the natural moisture , density , and Atterberg limit determinations were used to classify the soils . These tests were performed in accordance with the current American Society SEG # 0109 -307 Page 4 for Testing and Materials (ASTM) Procedures . The results of these determinations are presented at their respective sample depths on the boring logs . 2.2.2 Strength Tests Unconfined compression tests were performed on selected samples of the cohesive soils and the limestone . In the unconfined compression test, a cylindrical specimen is subjected to an axial load applied at a constant rate of strain until failure or a large strain occurs . Strengths determined by this test are tabulated at their respective sample depths on the boring logs. Six Triaxial shear tests were performed on specimens from selected samples of near surface soils to evaluate shear strength properties of the subgrade soils. The Triaxial shear tests included Unconsolidated-Undrained (UU) tests . These tests were performed by ML Testing, LLC. The results of these tests are presented on Figures 11 through 16 . 2.2.3 Free Swell Tests Selected samples of the near-surface cohesive soils were subjected to Free Swell tests. In the Free Swell test, a sample is placed in a consolidometer and subjected to the estimated overburden pressure . The sample is then inundated with water and allowed to swell. Moisture contents are determined both before and after completion of the test. Test results are recorded as the percent swell , with initial and final moisture content. The Free Swell test results are shown on Figure 17 . These test results are used to estimate the post-construction vertical swell of the subgrade . 2.2.4 Lime Series The Eades and Grim lime series test is a test where the optimum percentage of hydrated lime required to stabilize and increase the strength of a clayey soil is determined . When hydrated lime is mixed with a clayey soil, a pozzalanic reaction and a calcium substitution occur, and the resulting soil-lime mix becomes more granular in texture and its strength increases . In the Eades and Grim lime series test , several specimens form a soil sample are mixed with varying percentages of hydrated lime and the pH of the resulting soil-lime mixtures is determined. The optimum percentage of hydrated lime required to stabilize the soil is the combination of the minimum percentage of hydrated lime required to produce a pH of about 12.42 for the soil lime SEG # 0109-307 Page 5 mixture and the min imum percentage of hydrated lime added to the soil sample beyond which the pH of the soil -lime mixture does not increase significantly. For construct ion purposes , an addit ional 1 to 2 percent is added to the previously determ ined optimum amount of hydrated lime. The results of the Eades and Grim lime series test are presented on Figure 18 . 2.2.5 Soluble Sulfate Soluble sulfate tests were conducted on selected soil samples recovered from the test borings . The sulfate testing was conducted to identify sulfate-induced heaving potential of the soils which can cause detrimental volumetric changes to the lime modified subgrade. Selected samples of the subgrade soils were shipped to Xenco Laboratories for testing . The tests were conducted in accordance with TXDOT 145 E. The full Xenco report is available on file . The results of the sulfate tests are summarized on Figure 19 . Generally , elevated risk of sulfate induced heave occurs at concentration levels ranging from 2,000 to 3,000 ppm . Based on the analytical test results , the samples sulfate concentrations ranged from 200 to 300 ppm indicating low risk of sulfate induced heave . It should be noted that the limited amount of risk always exist due to the inherit limi tations of the testing techniques . However, the res idual soil of the Paw Paw formation is not known to be a concern of sulfate induced heave . 2.3 Review The site soil and rock stratigraphy was described in the fie ld by our dri llers. These descriptions were later modified in accordance with the results of the laboratory tests and visual examinations of the samples performed in the labo ratory. All recovered soil samples were examined , classified , and described in general accordance with the appropriate ASTM and Un ified Soil Classification System (USCS) procedures . Classifications of the subsurface materials and finalized descriptions of soil and rock strata are shown on the attached boring logs. 3.0 GENERAL SUBSURFACE CONDITIONS 3.1 Site Geology Accord ing to the Dallas Sheet of the Geological Atlas of Texas , the project site is located in an undivided mapping unit which includes the Pawpaw Formation , Weno Limestone and Denton SEG # 0109-307 Page 6 Clay of the lower Cretaceous age . The predominant formation based on the results of the test borings appears to be the Weno Formation . The Weno Formation is approximately 70 feet thick and is composed of interbedded clays , shales , marls and limestone . The Pawpaw, Weno and Denton formations typically weathers to form residual deposits of moderately to highly active clay soils . 3.2 Stratigraphy Details concerning the subsurface materials and conditions encountered are shown on the boring log . The stratification lines shown on the boring log represent approximate locations of changes between soil types; in-situ, the transition between materials may be gradual. Generally, subsurface materials within the 10-ft maximum depths explored can be summarized in the following table : Table 2: Summary of Subsurface Conditions Stratum Description First Bottom of Encountered (ft) Stratum (ft) !

Advancing the borings using dry, continuous flight auger drilling methods allows us to observe of the initial and subsequent zones of seepage and record their levels. At the time the borings were advanced , groundwater seepage levels were not encountered in any of the test borings during or at completion of the drilling activities. Typically , shallow groundwater in the Pawpaw geologica l formation flows horizontally through the porous , tan, weathered limestone below the plastic clays and above the less permeable gray limestone. The quantity of the groundwater flows depends on several factors including local permeabil ity , depth to gray limestone , seasonal precipitation , etc. It is not possible to accurately predict the magnitude of subsurface water fluctuations that might occur based upon short-term observations. Future construction activities may also alter the surface and subsurface drainage characteristics of this site . If a noticeable change from the conditions is observed prior to construction , then this office should be notified immediately to review its effect on the des ign recommendat ions . 4 .0 ANALYSIS AND RECOMMENDATIONS SEG # 0109-307 Page 8 The following design recommendations have been developed on the basis of the previously described project characteristics and subsurface conditions encountered . If there are any changes in the project criteria , such as relocating the building on the site or the amount of cutting and filling , a review should be made by the geotechnical engineer to evaluate if any further field exp loration and/or modifications in our recommendations contained herein will be requ ired. The geotechnical engineer should be retained to rev iew final project plans and specifications for compliance with the recommendations of this study . 4.1 General Considerations Typically, the traffic in residential subdivisions consists of light automob iles , pickup trucks , panel vans, buses, construction vehicles , trash haulers and dumpsters , and 18-wheel trucks that can be partially .or fully-loaded to a 80-kip capacity. All the different traffic types are converted into equivalent 18-kip single axle loads (ESAL) and the thickness of the pavements becomes a funct ion of the ESAL applications. For the driveways and alleyways we have assumed that the design traffic is on the order of 5,000 ESAL repetitions. For the 2 lane res idential streets , the design traffic is assumed to be 35 ,000 ESAL repetitions for 25 years service life . Based on the visual observations , we estimate that the exposed subgrade is w ithin +/-1-ft of the finished subgrade elevations. The surficial soils encountered at the test borings consisted of diverse materials ranging from moderately to highly plastic ~lay soils. 4.2 Potential Vertical Movements The near-surface clay are considered to be moderately highly expansive and are capable of vertical and horizontal ground movements due to soil swell and shrinkage which occurs with changes in soil moisture content. The magnitude of the movements experienced by the pavement will depend on the moisture content and the thickness of clays at the time of construction, so il plasticity, rainfall moisture index , the local dra inage characteristics, and other rela ted factors . Based on the soil conditions and the clay depth , the magnitude of the soil swelling have been estimated using TxDOT Method Tex 124-E. Potent ial vertical movements on the order of 2 to 4 inches are estimated in most SEG # 0109-307 Page 9 years . Significantly more movements (in excess of 2 to 4 inches) can occur if poor drainage , excess ive water collections , leaking pipelines , etc. occur. In order to minimize rainwater infiltration through the pavement surface , and thereby minimize future upward movement of the pavement slabs , all cracks and joints in the pavement should be sealed on routine basis after construction . Swell ratios were ana lyzed based on the current moisture conditions and the percent swell obta ined from the test borings . The swell ratios for all the test borings were 1.0 or greater. Therefore lime stabilization was considered in accordance with the City of Fort Worth Pavement Design Manual. 4.3 Sulfate-Induced Heaving Soluble su lfate testing was conducted to check for sulfate-induced heaving potential. Sulfate induced heaving is caused when hydrated lime is added to a soil with high sulfate concentration . The lime reacts with the sulfates caus ing large volumetric changes in the soil. Portland cement can also produce such large heave as a byproduct of hydration . Generally , elevated risk of sulfate induced heave occurs at concentration levels rang ing from 2 ,000 to 3 ,000 ppm . Based on the analytical test results , the samples sulfate concentrations ranged from 200 to 300 ppm indicating low risk of sulfate induced heave. It should be noted that the lim ited amount of risk always ex ist due to the inherit limitations of the testing techniques . However, the residual soil of the Weno geological format ion is not known to be a concern of sulfate induced heave. These test results suggest that the potential for sulfate attack w ith in the near-surface soils is negligible . Therefore , we recommend using Type I cement concrete mix with a water-cement ratio limited to 0.45 or less . 4.4 Pavement Analysis Unconsolidated-undrained triaxial (UU) strength tests were performed on selected clay samples retrievea from the test borings. The (UU) test results were correlated to the California Bearing Ratios (CBR), and the residual modulus of the subgrade reaction as presented in Plate B.1 of the City of Fort Worth Pavement Design Manual. SEG # 0109-307 Page 10 The rigid pavement design for each street was then performed using 1993 AASHTO manual and DARWIN 3.0 software developed by AASHTO . · The design was based on the following assumptions : Pavement Type-Jointed Reinforced Concrete Pavement 18 Kips-ESAL is 35 ,000 for high volume residential street Design Life is 25 years with no growth . In itial Serviceability -4.5 and Terminal Serviceability -2.0 28-day Mean PCC Modulus of Rupture-600 psi 28-Day mean elastic modulus of slab-4 ,040 ,000 Reliability -80%, Standard Deviation -.35 , Load Transfer Coefficient (J)-3 .0 Over all dra inage Coefficient Cd of 0 . 7 The computer program calculates the Mean Effective K-Values based on the input of the resilient modulus of both the raw subgrade and the base materials . The pavement thickness at the location of each test boring is shown in the following section. 5 .0 PAVEMENT RECOMMENDATIONS 5 .1 Lime Treated Subgrade Preparation Surficial clays present at this site are moderately active , and are subject to losses in shear strength with the increases in moisture content which normally occur beneath area paving. They typically react with hydrated lime, which serves to improve their support value at higher mo isture levels , and provide a firm , uniform subgrade beneath the paving. Based on the Atterberg Limits tests , 6 percent hydrated lime by dry weight (27 pounds per square yard per 6 inch depth) should be adequate to stabilize the existing clay subgrade soils . The lime should be thoroughly mixed and blended with the top 6 inches of the subgrade (TxDOT Item 260) and the mixture compacted to a minimum of 95 percent of maximum dry density as determined in accordance with ASTM D 698 , within 3 percentage points of the soil's opt imum moisture content. SEG # 0109-307 Page 11 We recommend that this lime stabilization extend 2 feet beyond exposed pavement edges, if possible , in order to reduce the effects of shrinkage during extended dry periods . After blue top stakes are set in preparation for grading the lime stabilized subgrade , depth checks should be performed to verify that the specified depth of stabilization is present after final grading of the stabilized subgrade. Sand should be specifically prohibited beneath pavement areas during final grading (after stabilization), since these more porous soils can allow water inflow, resulting in heave and strength loss of subgrade soils. It should be specified that only lime-stabilized soil would be allowed for fine grading. After fine grading each area in preparation for paving, the subgrade surface should be lightly moistened , as needed, and recompacted to obtain a tight non-yielding subgrade . Therefore, in areas where sand is exposed at the surface, it should be over excavated and replaced with on-site clayey materials prior to stabilization for optimum results . Project specifications should allow a curing period between initial and final mixing of the lime/soil mixture. After initial mixing , the lime treated subgrade should be lightly rolled and maintained at or within 5 percentage points above the soil's optimum moisture content until final mixing and compaction. We recommend a 3-day curing period for these soils . The following gradation requirements are recommended for the stabilized materials prior to final compaction: Minimum Passing 1 3/4" Sieve Minimum Passing No. 4 Sieve Percent 100 60 All nonslaking aggregates retained on the No . 4 sieve should be removed prior to testing. The prepared subgrade should be protected and moist cured or sealed with a bituminous material for a minimum of 7 days or until the pavement materials are placed. Pavement areas should be graded at all times to prevent ponding and infiltration of excessive moisture on or adjacent to the pavement areas . Due to the presence of expansive clay soils, some pavement movements should be anticipated, even if our recommendations are strictly followed. Inspection during construction is particularly important to insure proper construction procedures are followed. 5.2 Pavement Sections SEG # 0109-307 Page 12 The pavement design was performed using DARWIN 3.0 computer program which was developed in accordance with 1993 AASHTO Guide for Design of Pavements Structures. The following table summarizes the pavement depth at each boring location : Boring No. Street Name Subgrade Preparation PCC Thickness (inches) B-1 Glenmont Ct. 6 inches lime (27 lb/sy) 7 .5 B-2 Greene Avenue 6 inches lime (27 lb/sy) 7 .5 B-3 Odessa Avenue 6 inches lime (27 lb/sy) 7 .5 B-4 Wharton Drive 6 inches lime (27 lb/sy) 7.5 B-5 Wonder Drive 6 inches lime (27 lb/sy) 7.5 B-6 Indio Drive 6 inches lime (27 lb/sy) 7 .5 B-7 Peggy Drive 6 inches lime (27 lb/sy) 7.5 B-8 Natchez Trace 6 inches lime (27 lb/sy) 7 .5 B-9 Garrick Drive 6 inches lime (27 lb/sy) 7 .5 SEG # 0109-307 Page 13 Concrete quality will be important in order to produce the desired flexural strength and long-term durability. Assuming a nominal maximum aggregate size of 1 to 1 3/8 inches , we recommend that the concrete have entrained air of 5 percent (±1 % ) with a maximum water cement ratio of 0 .50. Proper joint placement and design is critical to pavement performance. Load transfer at all longitudinal joints and maintenance of water-tight joints should be accomplished by use of tie bars . Control joints should be sawed within 5 to 12 hours after placing concrete . Joints should also be properly cleaned and sealed as soon as possible to avoid infiltration of water, small gravel, etc. We have found that joint spacing on 12 to 15 foot centers have generally performed satisfactorily . Expansion joints should be on a 45-foot spacing and be sealed with an elastomeric joint sealant. It is our recommendation that the concrete pavement be reinforced with No . 3 bars on approximately 18-inch centers in each direction or equivalent reinforcing steel. In loading dock areas we recommend that the perimeter of the pavement area have a stiffen ing curb section to prevent possible distress due to heavy wheel loads near the edge of the pavement and also to provide canalized drainage. 5.3 Special Pavement Considerations It is recommended that provisions be made in the contract to provide for proofrolling in entire pavement areas . It is also recommended that an item be included for removal and replacement of soft materials, which are identified by this procedure . Proofrolling can generally be accomplished using a heavy (25 ton or greater total weight) pneumatic tired roller making several passes over the areas. Where soft or compressible zones are encountered, these areas should be removed to a firm subgrade. Wet or very moist surficial materials may need to be undercut and either dried or replaced with proper compaction or replaced with a material, which can be properly compacted. Any resulting void areas should be backfilled to finished subgrade in 6 inch compacted lifts compacted to 95 percent of maximum dry density as determined by ASTM D 698 . SEG # 0109-307 Page 14 Achieving the required field density is dependent upon the adequate pulverization of the clay fill materials , the magnitude of compaction energy and the maintenance of field moisture near optimum . All joints and pavements shou ld be inspected at regular intervals to ensure proper performance and to prevent crack propagation . 6.0 EARTHWORK GUIDELINES It is possible that variations in subsurface conditions will be encountered during construction . Construction problems , particularly as to degree or magnitude, cannot be anticipated until the course of construction . Recommendations offered in the following paragraphs are not intended to limit or preclude other conceivable solutions but rather to provide the client with our observations based on our experience and our understanding of the project characteristics and subsurface conditions . To ensure that the recommendations conta ined in this study are adhered to , the geotechnical engineer should be retained by the client to review tests and observations performed during construction. 6.1 Site Preparation Prior to fill placement , if any , we recommend that the exposed subgrade be carefully inspected by proofrolling to compact pockets of loose soil and expose additional areas of weak , soft , or wet soils . The proofrolling operation must be performed under the observation of a qualified geotechnical engineer. Proofrolling consists of rolling the entire subgrade with a heavi ly loaded tandem axle dump truck or other approved equipment capable of applying similar wheel loads . Any soft, wet or weak fill or natural soils observed during proofrolling should be removed and replaced with well - compacted material as outlined in Section 6.2. Care should be exercised during the grading operations at the site. The traffic of heavy equipment, including heavy compaction equipment, may create a general deterioration of the shallower soils . Therefore , it should be anticipated that some construction difficulties could be encountered during periods when these soils are saturated and that it may be necessary to improve , remove or simply stay off of the saturated soils. 6.2 Fill Composition/Compaction SEG # 0109-307 Page 15 All soil materials used as fill should be free of deleterious material. All clayey soils should be compacted to a dry density of at least 95 percent, but not exceeding 98 percent , of the Standard maximum dry density (ASTM 0-698 Method A). The compacted moisture content of the clays during placement should be at optimum and not exceeding 4 percentage points above the optimum moisture content. Select fill brought in from off-site , if needed , should consist of a uniform , homogeneous , non- expansive silty clay , sandy clay or clayey sand soil with a liquid limit (LL) between 20 and 35 and have a plasticity index (Pl) of not less than 5 or greater than 15 . All select fill should be moisture processed within -3 to +3 percentage points of the materials optimum moisture content and compacted to a dry dens ity of at least 95 percent of the Standard max imum dry density . Compaction should be accomplished by placing the fill in 6 to 8 inch thick loose lifts and compacting each lift to at least the specified min imum dry density. It is imperative that the fill materials not exceed four inches in maximum size . If larger fragments or clods are encountered during grading , they must be broken down prior to final placement and compaction in the fill. In order for the fill materials to perform as intended , the fi ll material must be placed in a manner which produces a good uniform fill compacted within the density and moisture ranges outlined in the preceding paragraphs . Density testing must be performed on fill so ils to confirm this performance as construction progresses. In the building area fills , we recommend that each lift be tested at a frequency of no less than 1 test per lift. 6.3 Groundwater We don 't anticipate groundwater seepage in the shallow excavation . If groundwater seepage is encountered during the building pad excavation , we recommend grading the subgrade toward the corners of the excavations and pump the water out to a suitab le drainage system . 7.0 GENERAL COMMENTS SEG # 0109-307 Page 16 The analysis and recommendations presented in this study are based upon the data obtained from the test borings at the indicated locations and from any other information discussed herein .

Figure 10 Application LIME STABILIZATION RECOMMENDATIONS FOR PAVEMENT SUBGRADE SOILS PROPOSED STREETS FORT WORTH, TEXAS The hydrated lime should be applied only in the area where the first mixing operations can be completed during the same working day. The hydrated lime should be placed by the slurry method. The hydrated lime should be mixed with water in trucks or in tanks and applied as a thin water suspension or slurry . The distributor truck or tank should be equipped with an agitator, which will keep the lime and water in a uniform mixture . Approximately 32 pounds of hydrated lime per square yard will give the 7 percent required for a 6-inch thick stabilized subgrade . By calculating the number of square yards in each area and by knowing the amounts per truck load , the rate of application can be checked very closely . Mixing The material and hydrated lime should be thoroughly mixed by a rotary mixer or other device to obtain a homogeneous, friable mixture of material and lime free from all clods or lumps and left to cure from one to four days . From our experience, we have found that a curing period of 48 to 72 hours is adequate. During the curing period, the material should be kept moist. Final Mixing After the required curing time , the material should be uniformly mixed with a rotary mixer capable of reducing the size of the particles so that when all non-slaking aggregates (asphalt particles) retained on the No. 4 sieve are removed, the remainder of the material shall meet the following requirements when tested dry by laboratory sieves : Minimum passing 1-3/4" sieve -100% Minimum passing No. 4 sieve -60% During the interval of time between applications and mixing, the hydrated lime should not be exposed to the open air for a period of over six hours. A-1 Compaction Compaction of the mixture should begin immediately after final mixing , and no later than three calendar days after final mixing . The material should be aerated or sprinkled as necessary to provide the optimum moisture . Compaction should begin at the bottom and continue until the entire depth of mixture is uniformly compacted . All irregularities , depressions, or weak spots which develop must be corrected immediately by scarifying the areas affected, adding or removing material, and reshaping and recompacting by sprinkling and rolling . The surface should be maintained in a smooth condition -free from undulations and ruts . The subgrade should be compacted to a minimum of 95 percent of Standard Proctor density (ASTM D 698), at a moisture content within 3 percentage points of optimum moisture content. Compaction and moisture checks should be taken within all paving areas at the rate of one field density test per lift, per each 5,000 square feet. These tests are necessary to determine if the recommended moisture and compaction requirements have been attained. After the required compaction is reached, the subgrade should be brought to the required lines and grades and finished by rolling with a pneumatic tire or other suitable roller sufficiently light to prevent hair cracking.

MS/MSD recoveries were found to be outside of the laboratory control limits due to possible matrix /chemical interference, or a concentration of target analyte high enough to effect the recovery of the spike concentration. This condition could also effect the relati ve percent differenc e in the MS/MSD . 8 A target analyte or common laboratory contaminant was identified in the method blank . Its prese nc e indicates possible field or laboratory contamination. D The sample(s) were diluted due to targets detected over the highest point of the calibration curve, or du e to matrix interference . Dilution factors are included in the final re s ults . The re s ult is from a diluted sample. E The data exceeds the upp er calibration limit ; therefore , the concentration is reported as estimated. F RPD exceeded lab control limits. J The target analyte was positively identified below the MQL and above th e SQL. U Analyte was not detected. L The LCS data for this analytical batch was reported below the laboratory control limits for thi s analyte. The department supervisor and QA Director reviewed data. The samples were either reanaly ze d or flagged as estimated concentrations. H The LCS data for this analytical batch was reported above the laboratory control limits. Supporting QC Data were reviewed by the Department Supervisor and QA Director. Data were determined to be valid for reporting . K Sample analyzed outside of recommended hold time. JN A combination of the "N" and the "J" qualifier.
