D-25 TRENCH PAVEMENT(PERMANENT) REPAIR (E2-19) FOR UTILITY CUTS The unit price bid under the appropriate bid item of the proposal shall cover all cost for providing pavement repair equal to or superior in composition, thickness, etc., to existing pavement as detailed in the Public Works Department typical sections for Pavement and Trench Repair for Utility Cuts, Figures 2000-1 through 2000-3. The results of the street cores that were conducted on the project streets, to determine HMAC depths on existing streets, are provided in these specifications and contract documents. All required paving cuts shall be made with a concrete saw in a true and straight line on both sides of the trench, a minimum of twelve(12)inches outside the trench walls. The trench shall be backfilled and the top nine (9) inches shall be filled with required materials as shown on paving details, compacted and level with the finished street surface. This finished grade shall be maintained in a serviceable condition until the paving has been replaced. All residential driveways shall be accessible at night and over weekends. *W It has been determined by the Transportation and Public Works Department that the strip of existing HMAC pavement between the existing gutter and the edge of the trench pavement repair will not hold up if such strip of existing pavement is two(2)feet or less in width. Therefore, at the locations in the project where the trench wall is three (3) feet or less from the lip of the existing gutter, the Contractor shall be required to remove the existing paving to such gutter. The pavement repair shall then be made from a minimum distance of twelve (12) inches outside the trench wall nearest the center of the street to the gutter line. The pavement shall be replaced within a maximum of five (5) working days, providing job placement conditions will permit repaving. If paving conditions are not suitable for repaving, in the opinion of the Owner, the repaving shall be done at the earliest possible date. A permit must be obtained from the Department of Engineering Construction Services Section by the Contractor in conformance with Ordinance No. 3449 and/or Ordinance No. 792 to make utility cuts in the street. The Department of Engineering will inspect the paving repair after construction. This permit requirement may be waived if work is being done under a Performance Bond and inspected by the Department of Engineering. 11129104 SC-14 PART D - SPECIAL CONDITIONS D-26 SITE SPECIFIC TRENCH SAFETY SYSTEM (COVERS ALL PROJECTS) A.

ACP is defined under NESHAP as a Category II, non-friable material in its intact state but which may become friable upon removal, demolition and/or disposal. Consequently, if the removal/ disposal process renders the ACP friable, it is regulated under the disposal requirements of 40 CFR 61.150. A NESHAP notification must be filed with the Texas •• Department of Health. The notification must be filed at least ten days prior to removal of the material. If it remains in its non - friable state, as defined by the NESHAP, it can be disposed as a conventional construction waste. The Environmental Protection Agency (EPA) defines friable as material, when dry, which may be crumbled, pulverized or reduced to powder by hand pressures. .. C. The Generator of the hazardous material is responsible for the identification and proper handling, transportation, and disposal of the material. Therefore, it is the policy of the City of Fort Worth that the Excavator is the Generator regardless of whether the pipe is friable or not. ' D. It is the intent of the City of Fort Worth that all ACP shall be removed in such careful and prudent manner that it remains intact and does not become friable. The Excavator is Im responsible to employ those means, methods, techniques and sequences to ensure this result. Im E. Compliance with all aspects of worker safety and health regulations including but not limited to the OSHA Asbestos Standard is the responsibility of the Excavator. The City of Fort Worth assumes no responsibility for compliance programs, which are the responsibility of the Excavator. (Copy of forms attached) F. The removal and disposal of ACP shall be subsidiary to the cost of installing the new pipe unless otherwise stated or indicated on the project plans or contract documents. D-68 STORM WATER POLLUTION PREVENTION (FOR DISTURBED AREAS GREATER " THAN 1 ACRE) PERMIT: As defined by Texas Commission on Environmental Quality(TCEQ) regulations, a Texas Pollutant Discharge Elimination System (TPDES) General Construction Permit is required for all construction activities that result in the disturbance of one to five acres (Small Construction Activity)or five or more acres of total land (Large Construction Activity). The contractor is defined as an "operator" by state regulations and is required to obtain a permit. Information concerning the permit can be obtained through the Internet at http://www.tnrcc.state.tx.us/permitting/water .r perm/wwperm/construct.html. Soil stabilization and structural practices have been selected and designed in accordance with North Central Texas Council of Governments Best Management Practices and Erosion Control Manual for Construction Activities (BMP Manual). This manual can be obtained through the Internet at www.dfwstormwater.com/runoff.html. Not all of the structural controls discussed in the BMP Manual will necessarily apply to this project. Best Management Practices are construction management techniques that, if properly utilized, can minimize the need for physical controls and possible reduce costs. The methods of control shall result in • minimum sediment retention of not less than 70%. 11129104 SC-50 PART D - SPECIAL CONDITIONS NOTICE OF INTENT(NOI): If the project will result in a total land disturbance equal to or greater than 5 acres, the contractor shall sign at the pre-construction meeting a TCEQ Notice of Intent (NOI)form prepared by the engineer.

WORK TO BE DONE: The work to be done under this contract consists of rehabilitation of existing, sewer lines by the Cure-in-Place Pipe Method or approved equal. Cured-in- place pipe consists of a resin impregnated flexible tube, coated with an elastomeric coating, when inverted into an existing sewer pipe through existing access manholes, and which, under proper hydrostatic and thermal conditions, is cured-in-place, becoming a structurally sound cured-in-place pipe. The thickness of the pipe will be dictated by the structural requirements of the sewer pipe with no loss of cross sectional area other than the thickness of the resin-impregnated tube. The pipe will be impermeable to water, provide corrosion resistance, and an optimum friction factor for the sewer flow. Branch .. connections shall be reinstated by a remote controlled cutting device. The work consists of providing all labor, equipment, transportation, materials, and supervision necessary to : 1. Thoroughly clean sewers as required for the installation of the resin-impregnated ! tube. 2. Inspect sewers by closed circuit color television (CCTV), including identifying and marking the location of each service connection. Cost subsidiary to Pre- Construction TV Inspection. 3. Notify residents at least 48 hours prior to service interruption. ! 4. Install the resin-impregnated tube of the correct thickness as specified. 5. Cut out all service connections by remote cutters and restore service within 18 hours. 6. Re-inspect by CCTV to verify satisfactory completion of work at time of lateral reinstatement. Cost subsidiary to Post-Construction TV Inspection. 7. Pump around all dry and wet weather flows to accommodate the process at each separate installation, as required. 8. Comply with all appropriate governmental agencies' regulations regarding traffic, safety procedures and permits, the cost of which is the responsibility of the Contractor. B. MATERIALS: The fiber felt tube shall be fabricated to a size that when installed will tightly fit the internal circumference of the conduit specified by the Owner.

MATERIALS- Not specified. ' C. EXECUTION Infiltration Testing_ All interior coated manholes and all partial replacement manholes shall be observed (tested)by the Contractor in the presence of the Engineer for sources of infiltration. Observations will be made during high groundwater conditions, wherever possible. rt. Manholes shall be tested after installation with all connections (existing and/or proposed)in place. Drop-connections and gas sealing connections shall be installed prior to testing. The lines entering the manhole shall be temporarily plugged with the plugs braced to prevent them from being drawn r• into the manhole. The plugs shall be installed in the lines beyond drop-connections, gas sealing connections,etc. The test head shall be placed inside the frame at the top of the manhole(so that the manhole frame seal is tested)and inflated in accordance with the manufacturer's recommendations. A vacuum of 10 inches of mercury shall be drawn,and the vacuum pump will be turned off. With the valve closed, the level of vacuum shall be read after the required test time. If the drop in the level is less than 14nch of mercury(final vacuum greater than 9-inches of mercury), the manhole will have passed the vacuum test. After a successful test, the temporary plugs will be removed. The required test time is determined from Table 1.

[Example: 'Pit A 30(thirty)foot deep, 48(forty-eight)inch Manhole Total Test Time would be 75.0 seconds. 45.0+6(5.0)=75.0 seconds](Values listed above are extrapolated from ASTM 0924-85). Manhole vacuum levels observed to drop greater than 1-inch of mercury(Final vacuum less than 9- .. inches of mercury)will have failed the test and will require additional rehabilitation. The Contractor shall make the necessary repairs to the already completed rehabilitation work at no additional compensation. If the failure of the vacuum test is determined to be due to preexisting conditions not on the manhole rehabilitation schedule for that manhole,this additional work may be authorized by the Owner's Representative. After completion of the additional rehabilitation the manhole shall then be re-tested as described above until a successful test is made. Only one payment for manhole vacuum testing will be made on each manhole. Vacuum testing is required on all manholes having interior rehabilitation. >1/02AN ASC-34 PART DA - ADDITIONAL SPECIAL CONDITIONS Inflow Testing: All partially rehabilitated manholes shall be dyed water tested unless the manhole has successfully passed the vacuum test. Manholes shall be dyed water tested in the presence of the Engineer. The dye test shall consist of applying a concentrated dye solution around the manhole frame. Dyed water shall be applied for at least ten minutes. Manholes observed to be actively leaking greater than one drip per five seconds will have failed the test and will not be acceptable. Manholes failing the test will require additional rehabilitation by the Contractor at no additional compensation. .. Other Testing: One(1) rehabilitated manhole will be randomly selected for further testing. A laboratory selected by the City will take core samples of wall sections of manholes with wall coatings. Testing of the core samples will be done to evaluate material thickness, compressive strength, flexural strength and slant shear bond strength. The following are the minimum required strength_s for cementitious and non-cementitious wall coatings: Compressive Strength. Compressive strength shall conform to ASTM C 495 and C 109 and shall meet or exceed a minimum 28-day break of 4,000 psi.

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 to 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.

We understand that the sanitary sewers will be installed by either open- cut or deep tunneling techniques. The maximum invert depth will be 15 feet for open cut option. The maximum invert depth for the water line installation is 10 feet below existing grade. Based on the subsurface condition revealed by the soil borings, the findings and recommendations of this report are summarized below: 1. The subsurface soils at the site generally consist of stiff to hard medium plastic sandy clays and silty clays to depths of 6 feet, 10 feet and 12 feet at the locations of borings B- 1, B-2 and B-3, respectively followed by tan and gray limestone and shale to the termination depth of the borings. 2. Groundwater was not encountered during drilling operations at the three boring locations. However, it should be noted that groundwater levels might fluctuate seasonally and with climatic conditions. 3. The results of our soil borings indicate that, depending on the pipe depth, generally stable cohesive soils will be encountered while tunneling at most of the boring locations. 4. The core data revealed that the existing pavement generally consists of 6 to 7 inches of asphalt over 5 to 17 inches of concrete. Please note that this executive summary does not fully relate our findings and opinions. Those findings and opinions are only presented through our full report. i 2 INTRODUCTION 2.1 Project Description HVJ Associates, Inc. was retained by Parsons to provide geotechnical services for the proposed 15- inch diameter sanitary sewer replacement along Throckmorton Street and, 121h street and Houston Street;and install a 12-inch water line along 141h Street from Throckmorton to Houston Street in the City of Forth Worth,Texas. We understand that the sanitary sewers will be installed by either open- cut or deep tunneling techniques. The maximum invert depth will be 15 feet for open cut option. The maximum invert depth for the water line installation is 10 feet below existing grade. A site vicinity map is presented on Plate 1. The purpose of this geotechnical investigation is to provide geotechnical design recommendations for the proposed sanitary sewer and water line installation. 2.2 Geotechnical InvesjUtion Progm The primary objectives of this study were to gather information on subsurface conditions at the site and to provide recommendations for the proposed sanitary sewer and water line installation. The objectives were accomplished by: 1. Drilling three (3) soil borings to determine soil stratigraphy and to obtain samples for laboratory testing; 2. Performing laboratory tests to determine physical and engineering characteristics of the soils;and 3. Performing engineering analyses to develop design guidelines and recommendations. Subsequent sections of this report contain descriptions of the field exploration, laboratory-testing program,general subsurface conditions,design recommendations,and construction considerations. 3 FIELD INVESTIGATION 3.1 Geotechnical Boring The field exploration program undertaken for the project was performed in October 26 &27,2005. Subsurface conditions along the project alignment were evaluated by drilling and sampling three soil borings. Soil borings B-1 and B-2 were drilled to 45 feet below existing grade and soil boring B-3 was drilled to 15 feet below existing grade. The boring logs are presented on Plates 6 through 8. Key to terms and symbols are shown on Plates 9 and 10. Borings were drilled using dry drilling techniques with truck-mounted drilling equipment. Drilling fluids were used during rock coring operations. A site plan showing the approximate boring locations is presented on the Plan of Borings,Plate 2. 3.2 Sampling Methods Cohesive soil samples were obtained using a 3-inch diameter thin-walled tube,which is pushed into the soil in general accordance with the ASTM D1587 standard. Split spoon samplers were used in cohesionless soils and where sample recovery in cohesive soils using the thin-walled tube was not possible. Samples were extruded in the field,visually classified,and an estimate of the undrained shear strength was obtained by means of the pocket penetrometer in cohesive soils. Samples were 1 subsequently wrapped and sealed for transport to our laboratory. All SPT tests and pocket penetrometers are recorded in the boring logs and included on Plates 6 through 8. Rock coring was performed with an NX core barrel,which was 2-inches in diameter and 5-foot in length. The rock cores obtained were measured in the field to obtain percent recovery and Rock Quality Designation (RQD). Percent recovery and RQD values are shown in percentages on the boring logs in Plates 3 through 5.Key to terms and symbols are shown on Plates 9 and 10. The pavement at each boring location was cored prior to advancing the borings. Soil samples were obtained continuously to the maximum termination depth of the borings. All project borings were backfilled with soil cuttings, bentonite, and cold-mix asphalt, where applicable,upon completion of drilling. 3.3 Water Level Measurements Groundwater levels in the borings were observed during and after completion of drilling. The water levels measured during drilling are reported on the boring logs, which are included in plates 6 through 8. 4 LABORATORY TESTING 4.1 Geotechnical Laboratory Testing Selected soil samples were tested in the laboratory to determine applicable physical and engineering properties. All tests were performed according to the relevant ASTM Standards. These tests consisted of moisture content measurements, pocket penetrometer, Atterberg Limits, unconfined compression,and dry unit weight. The Atterberg limit tests were utilized to verify field classification by the Unified Soils Classification System. The hand penetrometer and unconfined compression tests were performed to obtain the undrained shear strength of the soil. The type and number of tests performed for this investigation are summarized below: Type of Test Number of Tests Moisture Content (ASTM D2216) 19 Atterberg Limits (ASTM D4318) 4 Hand Penetrometer 11 Unconfined Compression(UC) 11 Dry Unit Weight(ASTM D 2166) 11 The laboratory test results are presented on the boring logs on Plates 6 through 8. 5 SITE CHARACTERIZATION 5.1 General Geol-ga A review of the University of Texas at Austin, Bureau of Economic Geology 1988 Geologic Atlas of Texas, Dallas Sheet indicates that the uppermost geologic formation underlying the study area is the"Pawpaw Formation"(map symbol Kfd, Fort Worth Limestone and Duck Creek 'u � Formation). This formation primarily comprise of Limestone and Clay. Limestone formation is light to medium gray, aphanitic to biosparite, burrowed, beds 0.2-2 feet becoming thicker and more massive southward. Clays are generally calcareous, in units 0.1-5 feet thick, medium gray to yellowish brown, and forms low rolling hills of thickness 25 to 35 feet. 5.2 Soil Strati MW Our interpretation of soil and groundwater conditions at the project site is based on information obtained at the boring locations only. This information has been used as the basis for our conclusions and recommendations. Significant variations at areas not explored by the project borings may require reevaluation of our findings and conclusions. Subsurface soils encountered along the project alignment are discussed below. The subsurface soils at the site generally consist of stiff to hard medium plastic sandy clays and silty clays to depths of 6 feet, 10 feet and 12 feet at the locations of borings B-1, B-2 and B-3, respectively followed by tan and gray limestone and shale to the termination depth of the borings. Details of the subsurface stratigraphy encountered in the borings are shown on the boring logs presented on plates 6 through 8. 5.3 Existing Pavement Thickness The existing pavement was cored at all the boring locations prior to the drilling operations. The existing pavement structure and thickness are presented in the following table. Boring Total Thickness Asphalt Thickness Concrete Thickness No. (inch) (inch) (inch) B-1 11 6 5 B-2 24 7 17 B-3 11 6 5 The core data revealed that the existing pavement.generally consists of 6 to 7 inches of asphalt over 5 to 17 inches of concrete. - 5.4 Groundwater Conditions Groundwater was not encountered during drilling operations at the three boring locations. However, it should be noted that groundwater levels might fluctuate seasonally and with climatic conditions. 6 DESIGN AND CONSTRUCTION RECOMMENDATIONS 6.1 General We understand that the project includes the installation of 15-inch diameter sanitary sewer replacement along Throckmorton Street and, 121h street and Houston Street; and install a 12-inch water line along 141h Street from Throckmorton to Houston Street. We also understand that the sanitary sewers will be installed by either open-cut or deep tunneling techniques. The maximum invert depth will be 15 feet for open cut option. The maximum invert depth for the water line installation is 10 feet below existing grade 3 a�� 6.2 Geotechnical Parameters Geotechnical design parameters are presented in the following table. Design parameters given in the table are based on field and laboratory test data obtained at boring locations only and at the approximate invert depth. It must be noted that because of the nature of the soil stratigraphy at this site, parameters at locations away from the borings may vary substantially from values reported in the table. Approx.

Use of the soil and rock properties shown above may or may not be appropriate for a particular analysis, since choice of design parameters often depends on whether total or effective stress analysis is used, rate of loading, duration of loading, geometry of loaded area, and other factors: The total unit weight values shown above represent our interpretation of soil and rock unit weight at natural moisture content. The undrained shear strength and allowable bearing pressure values represent our interpretation of the shear strength based primarily on the results of unconfined compression tests. Pipe Design. The loads imposed on underground pipes depend principally upon the method of installation, the weight of overburden soils, roadway traffic load, and loads due to existing surface structures. The traffic load applied to the pipe can be calculated using 85% of wheel load with an impact factor of 1.5 for one foot of soil cover, 50% of wheel load with an impact factor of 1.35 for 2 feet of cover, and 30% of wheel load with an impact factor of 1.15 for 3 feet of cover. This results in a total design traffic load on the pipe of about 1.28, 0.68 and 0.35 times the wheel load for 1, 2 and 3 feet of cover,respectively. For pipes with four or more feet of cover,the traffic loads may be taken as a surcharge equivalent to 250 psf. The design of flexible pipes requires the modulus of soil reaction of the native soil (En) in the trench wall as input. The En' values are based on empirical relationships to the soil consistency as defined by unconfined compression tests for cohesive soils. E„' values for the native soils are presented in the following table. The En'values for short-term conditions in cohesive soils may be assumed to be 1.5 times the long-term values. These values are based on the soil data obtained at the boring locations only and may be used for the noted invert depth zone.

A permanent liner is then placed some time after the installation of the primary liner. The annular space between the liners is then filled with grout. The tunnel liners should be designed to support not only the ground loads but also the construction loads. Pressures on the liner with an example calculation of liner load due to earth and traffic load are presented on Plate 3. Deformation of the liner in the horizontal and vertical diameters can be expected due to soil-liner interaction. Experience with liner distortion in the area suggest values in the range of 0.75 percent difference in length of the vertical and horizontal diameters;with shortening of the vertical diameter in most cases. To the extent that the tunnel liner reduces the soil deformation due to the rigidity of the liner, bending moments will be developed in the liner. The lining will be adequate with respect to bending if it can be deformed,without overstress,by an amount equal to the expected change in diameter. Buckling of the liner can be a problem if non-uniform support of the liner occurs. This sometimes happens if a local overcut situation occurs during tunneling which is not properly backfilled. Buckling can also occur if the liner is used as reaction for the tunneling equipment, and the tunneling equipment unevenly applies thrust loads. 6.4 Thrust Force Design Recommendations Ewing System Thrust Restraint Unbalanced thrust forces will be developed in water lines due to changes in direction, cross-sectional areas, or when the pipe is terminated. These forces may cause joints to disengage if not adequately restrained. There will be a slight loss of head due to turbulence in bends in the pipes. This loss will cause a pressure change across the bend, but it is usually small enough to be neglected. The thrust force may require more reaction than is available just from the pipe beating against the backfill. In order to prevent intolerable movement and overstressing of the pipe, suitable buttressing should be provided. In general, thrust blocks, concrete encasement, restrained joints and tie rods are common methods of providing reaction for the thrust restraint design. The thrust restraint design provisions described in this section are based on the American Water Works Association Manual M9 (1979) Concrete Pressure Pipe. Various types of thrust restraint systems are used depending on type of pipes and installation conditions. The force diagram shown on Plate 4 illustrates the thrust force generated by flow in a bend in the pipe. The equations for computing this thrust force are also given on this figure. An example computation of a thrust force generated by flow at a bend in a pipe for a surge pressure of 150 psi and a bend angle of 90 degrees is also presented on Plate 4. In a horizontal bend, the thrust restraint develops capacity through passive resistance. The capacity can be calculated by multiplying the beating area by the allowable passive resistance. If pipe can 5 tolerate some joint extension, an allowable passive pressure of 900 psf for clays may be used for design,which includes a factor of safety of 3. In order for the block to be effective, it must be cast against undisturbed soil and the face of the block must be perpendicular to the direction of and centered on the line of action of the thrust. A properly designed thrust block can fail if the soil behind the block is disturbed by subsequent excavation or if an adjacent utility line,which is not capable of supporting the thrust loads collapses. In a vertical bend, the thrust restraint develops capacity through a gravity thrust block. In addition, the thrust restraint available for upward oriented thrust forces is limited to the weight of the thrust block and soil above the thrust block. The minimum size of the block base can be determined by an allowable soil bearing pressure. We recommend using allowable bearing pressures as shown in the previous table in Section 6.2 of this report We believe that a factor of safety of three is appropriate for piping systems,which are sensitive to extensions at the pipe joints. Frictional Resistance. The unbalanced force produced by grade and alignment changes can also be resisted by friction on the pipe. The length of pipe will be formed by tying or welding joints together for the distance required to develop adequate capacity or by encasing the pipe in concrete. The resisting frictional force,FR is computed as FR = f(2We+Wa,+Wp) Where: f = Coefficient of friction between pipe and soil We =Weight of soil over pipe in lb/ft Wa =Weight of contained water in lb/ft Wp =Weight of pipe in lb/ft The friction value depends on the material in contact with the pipe and the soil used in the backfill around the pipe. For pipe surrounded by compacted sand or crushed stone, the friction between the pipe and soil may be based on a friction angle of 20 degrees. The allowable coefficient of friction, f, of 0.23 and 0.15 may be used for ductile iron and PVC pipe, respectively. These values may be after checking the manufacturing recommendation values and should include a factor of safety of 2.0. The weight of soil above the pipe will depend on the soil unit weight and the pipe depth. For compacted soils used for backfill,a total unit weight of 125 pcf can be used. Tied joints are used to transmit thrust across joints. These ties may be welded or harnessed joints. Joints may be welded in the field in order to transmit the thrust involved. Information concerning types of harnessed joints available and size and pressure limitations can be obtained from the pipe manufacturers. 6.5 Boring,Tacking. or Tunneling Construction Considerations It is planned to place the sewer along Throckmorton and Houston Streets by boring,jacking,or tunneling techniques. Three basic criteria exist for satisfactory construction. First,construction must be feasible which means that it is possible to advance the bore safely and to maintain the integrity of the bore opening at least temporarily. Second,the construction should not result in excessive damage to adjacent or overlying structures,streets, or utilities. Third, the long-term design objectives of the facility must be achieved. A summary of the construction conditions for the project is given below. 6 Pipe Design. For pipes to be installed by tunneling techniques,whereby sections of pipe are jacked forward against the surrounding soil, pipes should be designed to resist significant bending moments, along with the jacking forces exerted on the pipe during installation. These loads generally exceed the overburden pressures that are typically determined based on the prism earth load to the ground surface, plus hydrostatic pressure and surcharge loads as shown on Plate 3. Therefore, pipes designed to resist construction loads during tunneling operations should have adequate strength for most long-term overburden and traffic loads. During design, allowance should be made for any external loads, other than soil and rock loads, which may be exerted on the pipe. These include loads from foundations for structures located near the water line and any possible future excavation to be performed near the water line. Much of the stability of the waterlines is due to the presence of relatively uniform stress conditions in the soil around the pipe. Relief of the earth loads on one side of the waterline due to subsequent adjacent excavation could cause an overstress of the pipe. Alignment Constructability is determined to a large extent by the type of.soil or rock. The best conditions are full-faced conditions. Situations that are more difficult are mixed face conditions where two different types of soil and rock, or two different types of rock are encountered in the tunnel face simultaneously. These tunneling conditions should be avoided whenever possible. We do anticipate full-face conditions at the bores located at the proposed invert depth of 30 feet below existing grade. Where mixed face conditions are encountered control of the grade of the bore is more difficult to control,and local instability of the bore is more likely at and near locations where the boundary between two strata is exposed in the bore. Face Stability. The stability of the face is a function of the shear strength and stress-strain characteristics of the soil or rock,the overburden pressure,the geometry of the cross section,the time-dependent loss of strength,the delayed deformation of some soils,and the construction procedures. When the face consists of more than one kind of soil or rock,the stability of such a face may be assessed by analyzing the different materials independently. For the cohesive soil materials that may be encountered the stability of a face is determined by its existing undrained shear strength. The stability of the unsupported face of the tunnel may be evaluated by a ratio of the overburden pressure divided by the undrained shear strength of the soil assuming atmospheric air pressure in the tunnel. This ratio is referred to as the Overload Factor, OF. Based on the measured soil properties,OF values were 3.0 or less. Generally,a design value for the overload factor of 4 or less is desirable in cohesive soils. A value of 4 represents a practical limit below which tunneling may be carried out without difficulties. Higher OF values will frequently lead to large deformations of the soil around and ahead of the tunnel opening,with the associated problem of increased subsidence and possible deformations. It should be noted;however,that exposure time of the face is most important. At the moment of excavation, negative pore pressures are generated. If the soil is left under the same conditions,the pore pressures will dissipate resulting in a reduction of shear strength. Thus,if a slow rate of advance is expected,a higher value of the OF must be used (or a reduced corrected value for the undrained shear strength). Fill material from road grading or in old utility trenches may be encountered. A potential for face instability exists where weak fill soils are encountered. The contractor should be aware of these conditions and make provisions to avoid loss of ground where fill is encountered. Loss of Ground. A properly designed and controlled operation can eliminate or reduce immediate soil movement and subsidence to a tolerable leveL Nevertheless, some ground loss should be expected during boring or jacking construction operation. With good construction techniques, ground loss can be held to acceptable levels. Generally,sewers bored or jacked beneath pavement and buried utilities can be expected to create a loosened subgrade or bedding condition which may lead to subsequent deformations. The borings did not indicate the presence of groundwater. However,we recommend that equipment providing positive support to the face,such as earth pressure balance equipment,be used when constructing this segment of the project. Large ground loss can result from uncontrolled flowing ground. The potential for such ground loss exists wherever water-bearing sands or silts are encountered along the alignment. Careful dewatering of such layers will reduce the potential for development of flowing conditions. These soils were not encountered,however,if they are encountered during construction tunneling should be halted and measures need to be taken to dewater the area. Ground Surface Movements. The zone of influence of a bored or jacked crossing extends a distance equal to the invert depth on each side of the centerline of the alignment. No building structures are anticipated to be in the zone of influence. The utility lines located adjacent to or crossing the alignment may experience movement caused by boring or jacking. Settlement of the utility lines should be within acceptable limits provided good construction practices are followed. Long-term vertical movements caused by consolidation of the ground above the tunnel will occur if leakage into the liner or the sewer pipes impacts groundwater levels in the project area. 6.6 Manhole Designs The following sections discuss bearing capacity,uplift,and lateral earth pressure design criteria for the manholes,which may be constructed by open-cut excavation methods. Bearing Capacity:We understand that manholes will be approximately 15 feet deep from the ground surface,therefore;the base of the manholes will be founded on and in the shale. Therefore, the bearing capacity of the rock encountered at the proposed invert depth is at least 2500 psf and adequate to support the manhole. Uplift:, Buoyant uplift pressures will act on the portions of the manholes located below the water table. Groundwater was not encountered during the completion of the field borings, however a discussion is included. Buoyant uplift pressure is a function of the depth to groundwater. The largest uplift pressure will occur when groundwater is at the ground surface.We recommend that the manholes constructed by open-cut excavation method be designed to resist buoyant uplift based on the dead weight of the structure and the weight of any soil backfilled above the structure. If weight of the structure alone is inadequate to resist uplift forces,a toe may be constructed into the soil and rock at the base of the structure. Construction of a toe is appropriate when open-cut excavation methods are used. The toe may consist of a bottom slab that extends into adjacent backfill. The weight of the material above the extension can then be relied upon to resist the uplift forces. The unit weight of soils above and below the water table for a compacted backfill can be approximated as 125 and 65 pcf,respectively. The unit weight of the rock above and below the water table for a compacted backfill can be approximated as 135 pcf and 75 pcf respectively. Backfilling for manholes shall conform to the density requirements by the specifications. Lateral Earth Pressures: The pressures which a soil can be expected to exert on the exterior walls of an underground structure depend on the type of soil and the construction technique. If the construction method encompasses backfilling along the exterior walls of the underground structure, then the lateral earth pressures become a function of the type of backfill and its method of 8 placement. If construction were performed by incorporating temporary excavation sheeting as part of the permanent structure, then the lateral earth pressures would vary with the type of existing soil. For a backfill type of soil, the following considerations should be taken into account when estimating lateral earth pressure acting on the walls of a permanent underground structure. Over-compaction of backfill and utilization of highly plastic, expansive clay backfill are practices, which generally produce the highest wall pressures. In these cases, horizontal earth pressures exceeding the vertical pressure can be expected. Backfill selection and method of placement are critical. 1. Bank sand and select cohesive soil are some types of fill material that can be considered for this project. Bank sand is silty fine sand,which contains no more than 15 percent material by weight passing the number 200 sieve,clay lumps or balls not exceeding 2 percent,and is free of debris. Select cohesive soil should have a plasticity index between 7 and 20. Most of the excavated soils from this site are expected to be a mixture of cohesive materials with limestone,and shale. The backfill to be used should be tested prior to use as explained in the following section. The backfill around the underground structures will impose active to at rest earth pressures against the embedded walls. Design lateral pressures may be calculated for each backfill type using the following equivalent fluid densities for drained,level backfill. These pressures are for a restrained structure that is not free to rotate: Fill Type Equivalent Fluid Density (pcf) Excavated Limestone and shale 40 On-Site or Select Fill (PI <_20) 70 Bank Sand, Gravel 40 On-Site Cohesive Soil(PI>20) 90 The above pressures represent drained soil pressures only;an allowance for hydrostatic loads, due to groundwater and lateral loads due to surcharge, must be considered. We recommend a minimum surcharge load of 250 psf be included in the design. 6.7 Qpen Cut Construction Considerations The topics addressed in this section include construction considerations for trench excavation and manhole excavations. Prospective contractors for the project must evaluate potential construction problems on the basis of their review of the contract documents,their own knowledge of and experience in the local area,and on the basis of similar projects in other localities, taking into account their own proposed methods and procedures. Excavations should satisfy two requirements. First,the soil above final grade must be removed without disturbing the soil below excavation grade,which will support constructed facilities. Second,the sides and base of the excavation must be stable to prevent damage to adjacent streets and facilities as a result of either vertical or lateral movements of the soil. In addition, a satisfactory excavation procedure must include an adequate construction dewatering system to lower and maintain the water level below the lowest excavation grade. 9 Trench Excavation Considerations: The excavation and trenching operations shall be performed in accordance with 29 CFR Part 1926, subpart P, as amended; including rules published in the Federal Register, Vol. 54, No. 209, dated October 31, 1989, at a minimum. Soil types for use with OSHA tables are presented in the below table. Soil Tvpes for use with OSHA Tables from 29CFR Part 1926 OSHA'S SOIL TYPE Depth of Trench(ft) Boring No. 0-5 5-10 10-15 15-20 B-1 B B/Stable Rock Stable Rock Stable Rock B-2 B C Stable Rock Stable Rock B-3 B B B/Stable Rock - The planned trench excavation construction may be performed along alignments near existing utility installation (either crossing or paralleling the new alignments). We wish to caution that potential unstable fill material(trench backfill)may be encountered at these locations. The contractors should be aware of potential excavation stability problems while working in the vicinity of old trenches and the excavation system should be designed to accommodate this weak material(trench backfill). Excavation Stability: Besides the issue of worker safety in the excavations,there is the issue of damage to surrounding structures due to movement of the sides of an excavation. Shoring should not only provide worker safety,but also provide trench wall support. The contractor is responsible for having the shoring system designed by a licensed Professional Engineer. Manhole Construction: The proposed manholes may be constructed by open-cut excavations in accordance with the plans and specifications. For vertical-sided excavations, the principal problem related to satisfactory excavation procedures is the design and installation of sheeting and bracing to form vertical sides of the excavation. In addition, a satisfactory excavation procedure must include an adequate construction dewatering system to lower and maintain the water level below the lowest excavation grade. Groundwater was not encountered in the borings during drilling and the contractor should be prepared to dewater such that the groundwater table is lowered below the bottom of the invert depth and provide dry bedding conditions. 6.8 Groundwater Control Assessment of the need for groundwater control and installation of appropriate dewatering equipment is the contractor's responsibility. Groundwater was not encountered during the completion of the borings. The following comments are intended to represent common solutions to groundwater control problems encountered in similar soil conditions and may not be construed as dewatering system design recommendations. A conventional pump and sump arrangement may be adequate if water bearing cohesive soils are encountered during trench excavations. Well points or eductors may be utilized to lower the groundwater level to at least three feet below the excavation level where water bearing cohesionless soils are encountered. Well points are generally not effective below about 15 feet beneath the top of the well point, and deeper dewatering requires deep wells with submersible pumps and eductors. Based on the subsurface soils encountered,we anticipate groundwater to be controlled using deep wells with submersible pumps and eductors. In any case, the groundwater control system used must provide a relatively dry, stable base for construction. However,it should be noted that groundwater conditions will change due to rainfall and seasonal changes. Control of groundwater should be accomplished in a manner that will preserve the strength of the foundation soils;will not cause instability of the excavation;and will not result in damage to existing structures. Where necessary to this purpose, the water will be lowered in advance of excavation by pump and sump arrangement,wells,well points, or similar methods. Open pumping should not be permitted if it results in boils, loss of fines, softening of the subgrade, or excavation instability. Discharge should be arranged to facilitate sampling by the owner's representative or engineer. 7 LIMITATIONS This investigation was performed for the exclusive use of Parsons for the proposed Throckmorton sanitary sewer and water line in Fort Worth,Texas.
