J. Louis Construction of Texas Ltd., for Walnut Creek Sanitary Sewer, Phase I (City Project No. 00343) RECOMMENDATION: It is recommended that the City Council authorize the City Manager to execute a contract with S. J. Louis Construction of Texas Ltd., in the amount of$2,386,560.89 for Walnut Creek Sanitary Sewer, Phase I. DISCUSSION: On March 11, 2004, (M&C C-19993) the City Council authorized an Interlocal Agreement with the City of Benbrook for the extension of the Walnut Creek Sanitary Sewer Interceptor to provide sewer service to future developments in both cities. On August 10, 2004, (M&C C-20200) the City Council authorized an engineering agreement with Carter& Burgess, Inc., for design of the interceptor. On December 20, 2005, (M&C C-21227) the City Council authorized Amendment No. 1 to the Interlocal Agreement with Benbrook. The amendment updated the original cost responsibility of each City due to increased project cost as a result of increased sewer main footage and material costs. As part of the amendment, the estimated construction cost was revised to $2,471,189.00 with Fort Worth being responsible for $1,280,171.00 and Benbrook for$1,191,018.00. Benbrook subsequently deposited a check with the City for its cost share of the estimated construction cost along with $23,820.00 (2% of its share) for inspection costs. The project consists of the installation of approximately 7,200 linear feet of primarily 36-inch sanitary sewer pipe. The project was advertised for bid on December 8 and 15, 2005.

PART 3 -EXECUTION 3.1 PROCESSING AND MOISTURE-DENSITY CONTROL A. Following the spreading and mixing of the soil on the embankment, it shall be processed by discing 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 disc plow or three passes of a fully penetrating roto-till pulverize. Additional passes of the processing equipment shall be performed as necessary to accomplish breaking up, reduction of clod size, 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 recommended loose lift thickness prior to compaction is eight (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 content shall be applied evenly through each layer. B. Any layers which become damaged by weather conditions shall be reprocessed - to meet recommended requirements. The compacted surface of a layer of fill shall be lightly loosened by discing before the succeeding layer is placed. C. 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 are recommended for compacting sandier fill materials: D.

Provide manufacturers or producers test reports indicating compliance with these specifications. Make trial mixtures having proportions, consistencies, and air content suitable for the work based on methodology described in ACI 211.1, using at least three different water-cement ratios for each type of mixture, which will produce a range of strength encompassing those required for each class and type of concrete required on the project. The maximum water-cement ratios will be the equivalent water-cement ratio as determined by conversion from the weight ratio of water to cement plus pozzolan. Design laboratory trial mixtures for maximum permitted slump and air content. Make separate sets of trial mixture studies for each combination of cementitious materials and each combination of admixtures proposed for use.

In addition, plot a curve showing the relationship between 7 day and 28 day strengths. Design each mixture to promote easy and suitable concrete placement, consolidation and finishing, and to prevent segregation and excessive bleeding. D. Average Compressive Strength Required for Mixtures: Select the mixture proportions during mixture design studies to produce a required average compressive strength (fcr) exceeding the specified compressive strength (fc) by the amount indicated below. This required average compressive strength, fcr, will not be a required acceptance criteria during concrete production. However, whenever the daily average compressive strength at 28 days drops below fcr during concrete production, or daily average 7-day strength drops below a strength correlated with the 28-day fcr, adjust the mixture, as approved, to bring the daily average back up to fcr. During production, adjust the required fcr, as - appropriate, based on the standard deviation being attained on the job. E. Computations from Test Records: Where a concrete production facility has test records, establish a standard deviation in accordance with the applicable provisions of ACI 214.3R. Provide test records from which a standard deviation is calculated, which represents materials, quality control procedures, and w conditions similar to those expected; represents concrete produced to meet a specified strength or strengths (fc)within 1,000 psi of that specified for proposed work; and consists of at least 30 consecutive tests and be current to within the past 12 months. A strength test is the average of the strengths of two cylinders made from the same sample of concrete and tested at 28 days. For the required average compressive strength fcr used as the basis for selection of concrete proportions use the larger of the equations that follow based on the standard deviation determined above: fcr=fc+ 1.34S where units are in psi fcr= fc+2.33S- 500 where units are in psi Where S = standard deviation Where a concrete production facility does not have test records meeting the requirements above but does have a record based on 15 to 29 consecutive tests, establish a standard deviation as the product of the calculated standard deviation and a modification factor from the following table: NUMBER OF TESTS MODIFICATION FACTOR FOR STANDARD DEVIATION 15 1.16 03300 - 5 20 1.08 25 1.03 30 or more 1.00 F. Computations without Previous Test Records: When a concrete production facility does not have sufficient field strength test records for calculation of the standard deviation, determine the required average strength fcr as follows: 1. If the specified compressive strength fc is less than 3,000 psi: fcr=fc+ 1000 psi 2. If the specified compressive strength fc is 3,000 to 5,000 psi: fcr-fc+ 1,200 psi G.

This project will include multiple bore crossings as described in Section 5.1. Invert depths will generally be less than 15 feet except as noted below. The majority of the project will consist of open cuts. See plan of Borings (Figure 1) for site configuration and location. A; 1.2 PURPOSE AND SCOPE .ir The purposes of this geotechnical investigation were to: 1) explore the subsurface conditions at the site; 2) evaluate the pertinent engineering properties of the subsurface materials; 3) provide recommendations for the proposed improvements described above. This report was prepared in general accordance with our proposal -number PO4-0509E dated May 12, 2004. 2.0 FIELD INVESTIGATION The field investigation consisted of drilling five (5) test borings along the proposed alignment. The boring locations were located at the approximate locations shown on the Plan of Borings (Figure 1). A truck mounted auger drill rig was used to advance these borings and to obtain samples for laboratory evaluation. Undisturbed samples of cohesive soils were obtained at intermittent intervals with standard, thin-walled, seamless tube samplers. These samples were extruded MAS-TEK ENGINEERING & ASSOCIATES E04-1004 PAGE 1 in the field, logged, sealed, and packaged to protect them from disturbance and maintain their in-situ moisture content during transportation to our laboratory. 1 , The limestone strata encountered in the test borings were evaluated by the Texas Department of Transportation (TxDOT) Cone Penetration Test. The TxDOT Cone is driven with the resulting penetration in inches recorded for 100 blows. The results-of the TxDOT Cone Penetration Tests are recorded at the respective testing depths on the Logs of Borings. The results of the boring program are presented on the Logs of Borings, Figures 2 through 6. A key to the descriptive terms and symbols used on the logs is presented on Figure 7. 3.0 LABORATORY TESTING Laboratory tests were performed on representative samples of the soil to aid in classification of the soil materials. These tests included Atterberg Limits tests, -200 sieve tests, moisture content tests, and dry unit weight determinations. Hand penetrometer tests were performed on the soil samples to provide indications of the swell potential and the foundation bearing properties of the subsurface strata. Unconfined compressive strength tests were performed on soil samples to provide indications-of their bearing properties. The results of our testing program are presented on the Logs of Borings (Figures 2 through 6). The results of a laboratory sieve analysis is shown on Figure 8. 4.0 SITE AND SUBSURFACE CONDITIONS 4.1 GENERAL SITE CONDITIONS This project consists of approximately 6,000 lineal feet of sanitary sewer line to be constructed near the UPRR R.O.W. from Winscott Boulevard to Loop 820 in Benbrook, Texas. This project will include multiple bore crossings as described in Section 5.1. Invert depths will generally be less than 15 feet except as noted below. The majority of the project will consist of open cuts. See plan of Borings (Figure 1) for site configuration and location. MAS-TEK ENGINEERING & ASSOCIATES E04-1004 PAGE 2 4.2 SITE GEOLOGY As shown on the Dallas sheet of the Geologic Atlas of Texas, the proposed,alignment is located in an area underlain by the Goodland Limestone Formation. The Formation typically consists of hard to very hard limestone with some interbeds of clay, calcareous clay and weathered clay shale. This unit weathers to a tan color and is typically overlain by a layer or residual, dark colored clay. At this site, the limestone formation is overlain by alluvial overburden soils and fill soils as indicated on the boring logs.. 4.3 SUBSURFACE CONDITIONS Subsurface conditions encountered in the borings, including descriptions of the various strata and their depths and thicknesses, are presented on the Logs of Boring. Note that depth on all borings refers to the depth from the existing grade or ground surface. present at the time of the investigation. Boundaries between the various soil types are approximate. 4.4 GROUNDWATER CONDITIONS The borings were advanced using auger-drilling methods. Advancement of the borings using auger-drilling methods allows observation of the initial zones of seepage. Groundwater was MM encountered in all of the test borings. Water level measurements indicate groundwater levels at depths ranging from 11 to 16 feet below the existing ground surface. Shallow groundwater levels should be anticipated after periods of heavy rainfall. Results of the water level measurements are shown on the Logs of Borings (Figure 2 thru 6). It should be noted that groundwater was present at or above the proposed invert elevation at most of the test boring locations. It is not possible to accurately. predict the magnitude of subsurface water fluctuations that might occur based upon short-term observations. The subsurface water conditions are subject to change with variations in climatic conditions and are functions of subsurface soil conditions, rainfall, and water levels within nearby creeks. MAS-TEK ENGINEERING & ASSOCIATES E04-1004 PAGE 3 r t . 5.0 WATER LINE CONSTRUCTION 5.1 BORE CROSSINGS , ' Bore crossings are anticipated beneath the UP RR, Walnut Creek, US. 377, Vickery r Boulevard and Loop 820.. It is understood that the approximate invert depths for the bore crossings will range from 12 to 15 feet below the existing ground surface. As indicated on the Boring Logs, soil and rock conditions will vary considerably at the invert depths. Subsurface conditions will vary from water bearing clayey sand and gravel, to calcareous clay to very hard tan and gray limestone (with clay seams in some areas). Groundwater is present at varying depths as indicated on the boring logs and as indicated in Section 4.4 of this report. Based on the,highly variable soil and rock conditions along the proposed alignment, mixed face conditions ranging from hard rock to clay to water bearing sand and gravel will be encountered in horizontal bores. Conditions will vary from predominant hard rock to predominant clay and water bearing sand and gravel. These stratified conditions must be :t considered in evaluating means and methods of accomplishing horizontal bore excavations. ' 5.2 TRENCH EXCAVATIONS It is understood that open cut trench excavations will be performed along the majority of the alignment. It is understood that trench depths will be in the range of 10 to 15 feet deep. See Section 5.3.1 for considerations related to open cuts near active railroad tracks. As indicated on the boring logs, soil conditions will vary significantly. The soil conditions will vary and will include fill soil, calcareous clay, sandy clay, water bearing granular soils and hard to very hard limestone. Groundwater is present at varying depths as indicated on the boring logs. For trench excavations less than five feet in depth, and in stable clay soils, trench excavation may be cut near vertical in accordance with OSHA regulations, For excavations to any depth in sand, gravel, soft clay, fill materials, submerged soil, or unstable rock (fractured weathered MAS-TEK ENGINEERING &ASSOCIATES E04-1004 PAGE 4 limestone), or where seepage, or sloughing is observed, it will be necessary to employ either sloped excavations or temporary bracing. For excavation to depths in excess of five feet, it will be necessary to employ either sloped excavations or temporary bracing, regardless of the soil conditions encountered, General guidelines for the design of these two alternatives are discussed in the following sections. 5.3 OPEN CUTS Recommended slope ratios for the respective soil conditions are presented graphically on Figure 9. Trench excavation to depths of less than five feet in unstable soil or in weathered or fractured rock conditions should be cut back in a similar manner as described above. It should be recognized that free standing slopes will be less stable when influenced by groundwater or saturated by rain. Surcharge loads, such as those resulting from excavation spoil, or equipment, should be placed no closer than two feet from the crest of the slope, or in accordance with OSHA regulations. Vehicle traffic should be maintained at least five feet from the edge of the crest. Excavation may encounter non-compact fill soils placed during .previous construction of underground utilities. If encountered, these fill soils should be sheeted, shored, and braced, or laid back on slopes no steeper than 1.5 (H): 1(V). ®• 5.3.1 OPEN CUTS NEAR ACTIVE RAILROAD TRACKS Open cuts near active railroad tracks should be planned during time periods in which the railroad will not be active, if possible, whereby trench cuts, utility installations, backfilling and compaction can be completed prior to the next train activity. Active train movements induce �- surcharge dynamic loads and vibration into adjacent shored excavations. If it is not possible to. schedule utility construction during periods when train activity is not in progress, hydraulic ,�. shoring should be used to support the trench excavation during train activity. , The hydraulic jacks between the shored sheeting should be adequate to pre-stress the shored trench sidewalis so that no lateral embankment movement occurs during train activity. If -shored open cuts are planned near active rail, the earth pressure coefficients indicated on Figure 10 should be increased to 0.40 for all soil and rock conditions. Dynamic loads and MAS-TEK ENGINEERING & ASSOCIATES E04-1004 PAGE 5 vibrations from active rail lines should be included in design. Where the clear s acin between the trench sidewalls and the bottom of the railroad embankment and/gr the ballast shoulder is greater than 3H, where H is the trench depth, impacts to.short.term trench excavations are anticipated to be minor with respect to train activity. 5.4 TRENCH BRACING/BORE PIT SHORING Where site limitations require excavations to have .vertical side walls, an internal bracing system will be necessary. Bracing may consist of timber or steel shoring or manufactured steel trench braces. The lateral pressure distribution to be used in the design of trench bracing may be determined as presented on Figure 10. It should be recognized that pressures are not included from hydrostatic pressures, surcharge loads, or traffic live loads at trench side walls, dynamic loads, and vibration, which if present, must be included in bracing design. In lieu of a '- shoring system, a trench shield consisting of a prefabricated rigid steel unit adequate to withstand anticipated lateral pressures may be used. 5.5 DEWATERING' It should be anticipated that groundwater will be encountered in the propose excavations. Groundwater levels will be encountered at relatively shallow depths in some areas, particularly after periods of heavy rain (See Boring Logs). In areas where groundwater is encountered, a system of ditches, sumps and/or well points, and pumping will be required to provide groundwater control. The design of the actual dewatering system required is the contractor's responsibility. This includes the control of tail-water flow through previous backfilled sections. 5.6 CONSTRUCTION CONSIDERATIONS The following guidelines are presented to aid in the development of the excavation plans: Surface areas behind the crest of the excavations should be graded so that surface water does not pond within 15 feet of the crest, nor drain into the excavation. Heavy material stockpiles should not be placed near the crest of slopes per OSHA requirements. Similarly, heavy construction equipment should not pass over or be parked within 5 feet of the crest. MAS-TEK ENGINEERING & ASSOCIATES E04-1004 PAGE 6 The crest of slopes should be continually monitored for evidence of movement or potential problems. Freestanding slopes will become less stable when influenced by groundwater or saturation by rain. �mn 6.0 EARTHWORK GUIDELINES 6.1 TRENCH BACKFILL The excavated soils can be used for trench backfill. Use of rock fragments greater than six (6) inches in any dimension should be prohibited, since attaining uniform moisture and density without voids would be difficult. The backfill should be placed in thin compacted lifts as specified below. The fill materials should be free of surficial vegetation or debris. Clay and calcareous clay fill soils having a PI over 25 should be placed in 8 inch horizontal loose lifts and compacted to at least 95 percent of the maximum dry density as determined by ASTM D-698 test method. The clay and calcareous clay should be compacted at optimum to +3 above the optimum moisture content. Sand and sandy clay fill soils having a PI of less than 25 should be placed in 8 inch-horizontal loose lifts and compacted to at least 95 percent of the maximum dry density as determined by ASTM D-698 test method. These lower PI soils should be compacted at -2 to +2 of optimum moisture. 11 Broken limestone should be place in loose lifts of 8 inches and should be adequately crushed to where individual rock fragments have a diameter of less than 6 inches. The crushed limestone should be compacted at optimum to +4 percentage points above optimum moisture to a minimum of 95% Standard Proctor density (ASTM D-698). The limestone materials should be crushed and compacted using a compactor of sufficient size and weight to crush the rock. For fill depths below 15 feet and.25 feet depths respectively, the compaction level should be increased to 98% and 100% ASTM D698, respectively, where it is desired t reducepost- construction settlements. µ MAS-TEK ENGINEERING & ASSOCIATES E04-1004 PAGE 7 6.2 FIELD SUPERVISION AND DENSITY TESTING Field density and moisture content determinations should be made on each lift:of fill with a minimum of one test per lift per 150 linear feet of trench backfill. Many problems can be avoided or solved in the field if proper inspection and testing services are provided. It is recommended that site preparation, concrete placement, and fill compaction be monitored by a qualified engineering technician. Density tests should be performed to verify compaction and moisture content of any earthwork.
