EXCAVATION AND BACKFILL OF ACCESS PITS 1) Do not allow excavation over the limits of the bore or tunnel as specified . Trench walls of access pits adjacent to the bore or tunnel face shall be truly vertical. Shore the trench walls as necessary to protect workmen, the public, structures , roadways, and other improvements. 2) Excavations within the right-of-way and not under surfacing shall be backfilled , with type B backfill, and consolidated by tamping in 6" horizontal layers to 95% of maximum density as measured by ASTM D-698 . Surplus material shall be removed from the right-of- way and the excavation finished to original grades . Backfill pits immediately after the installation of the carrier pipe is completed . If carrier pipe is not installed immediately after casing pipe installation , the Right-of-Way Owner may require the access pits be temporarily backfilled until installation of carrier pipe. b . INSTALLING CARRIER PIPE IN CASINGS 1) Pipe to be installed within the casing or tunnel liner shall meet the requirements for this type of pipe as specified . Where indicated , place, align , and anchor guide rails and/or casing insulators inside the casing . If guide rails are used, place cement mortar on both sides of the rails . PART DA -ADDITIONAL SPECIAL CONDITIONS 2) Pull or skid pipe into place inside the casing . Lubricants such as flax soap or drilling mud may be used to ease pipe installation . Do not use petroleum products , oil or grease for th is purpose . If guide rails are used, install pipe and hold down jacks after installation of carrier pipe. 3) After installation of the carrier pipe , mortar inside and outside of the joints as applicable. Verify electrical discontinuity between the carrier pipe and tunnel liner. If continuity exists, remedy the short prior to applying cellular grout. 4) After carrier pipe installation is complete , if hold down jacks or casing spacers are used , seal or plug the ends of the casing . 5) After carrier pipe installation is complete , the annular space between the carrier pipe and tunnel liner or casing shall be completely filled with cellular grout. The Contractor shall take precautions to prevent flotation of the carrier pipe . Exterior joint coating (heat shrink sleeves) is required for polyurethane coated pipe. Provide necessary bulkheads as recommended by the cellular grout supplier. If pressure is used to apply grout , verify the maximum allowable pressure with the carrier pipe manufacturer, and do not exceed this pressure . c . FREE-AIR SYSTEM If required by OSHA standards, free-air systems shall be installed and maintained . d. INSTALLATION OF PRESSURE GROUT MIX 1) Install pressure grout mix in the void space between the outside of the casing pipe or tunnel liner and the excavation . For bore or jacks with casing pipe, install pressure grout mix immediately upon completion of setting casing pipe . For tunnel liner plate , install pressure grout mix at the end of each work day or more often as conditions warrant. 2) Unless specified otherwise , install pressure grouting through grout fitt i ngs for the casing pipe or tunnel liner plate 48" in diameter or larger. Grout fittings shall be fabricated into casing pipe and tunnel liner plate at a maximum spacing of 6'. Remove and plug grout fittings after pressure grouting . 3) Install pressure grout from the low end for all crossings where grout fittings are not used . Seal the low end and pressure grout until grout is extruded from the opposite end . 3. CROSSINGS INSTALLED BY BORING PART DA -ADDITIONAL SPECIAL CONDITIONS a . Perform the boring from the low or downstream end unless specified otherwise . Bore the holes mechanically and use a pilot hole . By this method , an approximate 2" pilot hole shall be bored the entire length of the crossing and shall be checked for line and grade. This pilot hole shall serve as the centerline of the larger diameter hole to be bored . Place excavated material near the top of the working pit and dispose of material as required . The use of water or other fluids in connection with the boring operation will be permitted only to the extent to lubricate cuttings. Jetting shall not be permitted . b. In unconsolidated soil formations , a gel-forming colloidal drilling fluid cons isting of at least 10% of high grade carefully processed bentonite may be used to consolidate cuttings of the bit , seal the walls of the hole , and furnish lubrication for subsequent removal of cuttings and installation of the pipe immediately thereafter. c . In locations where the so il formation is other than consolidated rock , insert the casing pipe simultaneously with the boring operation . This requirement applies to all bored holes of 18" or greater in diameter. For smaller diameter bored holes , it is desirable that the casing be installed as the boring progresses, but because of differences in soil formations , the time for inserting the casing shall be the Contractor's responsibility . In the event that caving sand or water bearing materials are encountered, insert the casing pipe simultaneously with the boring operation regardless of the diameter of the bored hole. In all cases , the security and integrity of the roadway is the primary concern. The Contractor shall be held fully responsible for the continued integrity of the structure of the roadway being crossed, whether or not a casing pipe is inserted simultaneously with the boring operation . 4 . CROSSINGS INSTALLED BY TUNNELING AND JACKING a . Jack the pipe from the low or downstream end, unless specified otherwise. Provide heavy duty jacks suitable for forcing the pipe through the embankment. In operating jacks , apply even pressure to the jacks used. Provide a suitable jacking head and bracing between jacks so that pressure will be applied to the pipe uniformly around the ring of the pipe . Provide a suitable jacking frame or back stop . Set the pipe to be jacked on guides, properly braced together , to support the section of the pipe and to direct it in the proper line and grade . Place the whole jacking assembly so as to line up with the direction and grade of the pipe . In general , excavate embankment material just ahead of the pipe and material removed through the pipe. Force the pipe through the embankment with jacks into the space provided . b . The excavation for the underside of the pipe , for at least 1/3 of the circumference of the pipe, shall conform to the contour and grade of the pi pe . Provide a clearance of not more than 2" for the upper half of the pipe . This clearance shall be tapered off to zero at the point where the excavation conforms to the contour of the pipe . Extend the distance of the excavation beyond the end of the pipe depending on the character of PART DA -ADDITIONAL SPECIAL CONDITIONS the material, but do not exceed 2' in any case. Decrease the distance if the character of the material being excavated makes it desirable to keep the advance excavation closer to the end of the pipe . c . If desired, use a c;;utting edge of steel plate around the head end of the pipe extending a short distance beyond the end of the pipe with inside angles or lugs to keep the cutting edge from slipping back onto pipe . d . When jacking of pipe has begun, carry on the operation without interruption to prevent the pipe from becoming firmly set in the embankment. Remove and replace any pipe damaged in the jacking operations . The Contractor shall absorb the entire expense . 5. CROSSINGS INSTALLED WITH TUNNEL LINER PLATE [Not Used] 6 . CROSSINGS WITH CASING INSTALLED BY OPEN CUT a . This article covers the requirements for the construction of crossings where pipe casing is required for installation by the open cut method . Excavation, backfill, and embedment of casing pipe shall be as specified in the construction plans . All other requirements shall be as specified herein.

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 responsible to employ those means, methods, techniques and sequences to ensure this result. 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 project involves installation of new water and sanitary sewer lines in Fort Worth, Texas. A site vicinity map is presented on Plate 1. The purpose of this geotechnical investigation is to provide geotechnical information at the proposed water and sanitary sewer locations. 2.2 Geotechnical Investigation Program The primary objectives of this study were to gather information on subsurface conditions at the site and to provide recommendations for the proposed utilities. The objectives were accomplished by: 1. Drilling five borings to determine soil stratigraphy and to obtain samples for laboratory testing; 2. Performing laboratory tests to determine physical and epgineering characteristics of the soils. Subsequent sections of this report contain descriptions of the field exploration, laboratory-testing program and general subsurface conditions . 3 FIELD INVESTIGATION 3.1 Geotechnica) Borings The field exploration program undertaken at the project site was performed on March 25, 2008. Subsurface conditions were investigated by drilling five 20-foot borings below the existing ground surface . All boreholes were backfilled with soil cuttings. A site plan showing the approximate boring locations is presented on the Plan of Borings, Plate 3. 3.2 Sampling Methods Soil samples were obtained continuously in the upper 10 feet and at 5-foot intervals thereafter. Cohesive soil samples were obtained with a three-inch thin-walled (Shelby) tube sampler in general accordance with ASTM D-1587 standard. Granular cohesionless soils were sampled with the Standard Penetration Test (SPT) sampler in accordance with ASTM D1586 standard. Each sample was removed from the sampler in the field, carefully examined and then classified. The shear strength of the cohesive soils was estimated by a hand penetrometer in the field. Suitable portions of each sample were sealed and packaged for transportation to our laboratory. Augering was performed when rock was encountered and TxDOT cone peiletrometer test was performed at approximately 5-foot intervals in the rock. The TxDOT cone test is used to determine the relative density or consistency of a soil material. The test consists of driving a 3-inch diameter cone with a 170-pound hammer, which is dropped for a distance of two feet. The cone is seated and driven to 12 blows or 6 inches whichever comes first. Then it is driven for two consecutive 6- inch increments, and the blow counts for each increment are noted. In hard materials, the cone is driven with the resulting penetration in inches recorded for the SO blows. The number of blows for 1 conclusions and recommendations. Significant variations at areas not explored by the project boring may require reevaluation of our findings and conclusions. . . Boring P. The subsurface soils at the site generally consist of stiff low plasticity clays at the top 4 feet, followed by weathered limestone to a depth of about 15 feet, followed by limestone to the maximum termination depth of 20 feet below ground surface. Boring Q. The subsurface soils at the site generally consist of very stiff high plasticity clays at the top 3.5 feet, followed by weathered limestone to a depth of about 14 feet, followed by limestone to the maximum termination depth of 20 feet below the ground surface. Boring R. The subsurface soils at the site generally consist of firm to stiff high plasticity clays at the top 4 feet, followed by weathered limestone to a depth of about 7 feet, followed by limestone to the maximum termination depth of 20 feet below ground surface. Boring $. The subsurface soils at the site generally consist of stiff to very stiff high to low plasticity clays at the top 9 feet, followed by weathered limestone to a depth of about 17 feet, followed by limestone to the maximum termination depth of 20 feet below ground surface. Boring T. The subsurface soils at the site generally consist of very stiff high to low plasticity clays at the top 8 feet, followed by weathered limestone to a depth of about 15 feet, followed by limestone to the maximum termination depth of 20 feet below ground surface. Medium dense clayey sands were encountered at the depth of 4 to 6 feet below ground surface. Details of the subsurface stratigraphy encountered in the borings are shown on the boring logs presented on the Plates 4 through 8. 5 .3 Groundwater Conditions Groundwater was encountered in borings R and S at the depth of 9 and 17 feet, respectively, below the existing ground surface during the drilling operations and at a depth of 11 feet immediately prior to borehole backfilling in boring S. It should be noted that groundwater levels determined during and after drilling may not accurately reflect the true groundwater conditions, and therefore should only be considered as approximate. Also these readings will fluctuate seasonally and in response to rainfall. Other factors that might impact groundwater levels include leakage from existing sewers and/ or sanitary sewers. 6 LIMITATIONS This investigation was performed for the exclusive use of Kimley-Horn and Associates, Inc. for the proposed Water and Sanitary Sewer Relocations for SH 121 T, Part II (South of Dirks Rd.) in Fort Worth, Texas. HVJ Associates, Inc. has endeavored to comply with generally accepted geotechnical engineering practice common in the local area. HVJ Associates , Inc. makes no warranty, express or implied. The analyses and recommendations contained in this report are based on data obtained from subsurface exploration, laboratory testing, the project information provided to us and our experience with similar soils and site conditions. The methods used indicate subsurface conditions only at the specific locations where samples were obtained, only at the time they were obtained, and only to the depths penetrated.

The proposed pipeline alignment has an approximate length of 2,400 feet. The 24" diameter waterline will be offered for bid with the following pipe material alternatives: • Bar-wrapped concrete cylinder pipe (CCP) (A WWA -C303). • Ductile iron pipe. • Dielectrically coated steel pipe. Upon completion of the corrosivity evaluation, a corrosion protection design was prepared including the requirements for joint bonding, electrical isolation, stray current control, corrosion control test stations and cathodic protection. This report presents the results of the corrosivity evaluation and corrosion protection design. 2.0 EXECUTIVE SUMMARY 2.1. Soils along the pipeline route are considered moderately corrosive to the concrete cylinder pipe (CCP), the ductile iron pipe (DIP) and the steel pipe material options. Corrosion protection measures are recommended for all three pipe alternatives to help preserve the physical integrity of the waterline. 2.2. The mortar coating on the CCP provides corrosion protection for the embedded steel components. Nevertheless, areas of low soil resistivity and high moisture content may compromise the level of corrosion protection in the long run, making the steel susceptible to corrosion. Therefore, it is recommended that the CCP option be cathodically protected. 2.3 . The annealing oxide and asphaltic ·shop coating typically present on the DIP option should be supplemented with the installation ofa polyethylene encasement and a cathodic protection system. 2.4. The dielectric coating on the carbon steel pipe option provides corrosion protection for this option. Nevertheless, low soil resistivity and high moisture content may compromise the level of corrosion protection in the long run, making the steel susceptible to corrosion. Therefore, it is recommended that the carbon steel pipe option be cathodically . protected to minimize the probability of corrosion at coating holidays. 2.5. Joint bonding of the CCP and DIP option is required to maintain the electrical continuity throughout the length of these piping options. Joint bonding of mechanical joints is also necessary for the steel pipe option. 2.6 . The evaluation indicates that AC or DC interference is not a concern for the waterline at this time. Nevertheless , re-evaluation of DC interference conditions will be necessary after installation of the proposed neighboring gas pipelines (if cathodically protected). 2.7. Test stations should be installed at galvanic anode ground bed locations, at cased crossings and at all buried underground in-line isolators to monitor the effectiveness of the cathodic protection system. 3.0 CORROSIVITY EVALUATION The soil corrosivity analysis and corrosion control recommendations presented in this report are based on the field soil resistivity survey and laboratory soil analysis conducted by Corrpro Companies, Inc. During the field evaluation Corrpro also investigated the possibility of interference due to stray DC currents and overhead high-voltage AC power lines which might affect the physical integrity of the planned water pipeline. The evaluation performed is the basis for determining the corrosion protection requirements for the concrete cylinder pipe (CCP), dielectrically coated steel pipe and ductile iron pipe (DIP) options. 3.1 RESULTS AND ANALYSIS Field and laboratory testing were performed to collect chemical and electrical data pertaining to the corrosivity of the proposed pipeline alignment with respect to the CCP, steel pipe and DIP options. Soil resistivity measurements were recorded from grade to depths of five , ten and fifteen feet at three (3) locations along the proposed pipe alignment. This data is recorded in Appendix A. 2 Using the Barnes Layer procedure, soil resistivities were calculated for the 5 to 10 feet and 10 to 15 feet layers. Statistical distribution of the soil resistivity for the layers of interest, where the water line is to be installed, is summarized as follows: 24" Diameter Waterline-Phase 2 Water and Sanitary Sewer Main Relocations for SH-121T Fort Worth, Texas Soil Resistivity 5-10 Feet 10-15 Feet Minimum 3,084 ohm-cm 1,875 ohm-cm Maximum 5,383 ohm-cm 4,522 ohm-cm Percent < 1,000 0% 0% Percent< 2,000 0% 33.3% Percent< 3,000 0% 66.7% Percent 2'.: 3,000 100% 33.3% Percent> 5,000 33.3% 0% Three (3) soil samples collected by geotechnical firm personnel along the pipeline right-of-way were tested in the laboratory for moisture content, pH, chloride, ion concentration, sulfide ion concentration, conductivity and resistivity. Laboratory test results are tabulated in Appendix B. With respect to the chemical properties of the soil, the test results of the samples indicate: • Moisture content from 8.20% to 19.0%. • A pH from 8.1 to 8.4. • Chloride ion concentrations from 1 ppm to 7ppm. • No detectable sulfide ions. • Conductivities from 170 to 780 microhmos. • Resistivities from 2,200 to 8,000 ohm-cm. Considering each of the chemical and electrical soil properties that are tested in the field and the laboratory, general guidelines for interpreting the results are as follows: • Soil Moisture -The higher the soil moisture content, the greater the anticipated rate of corrosion. Moisture contents can range from 1 % (very dry sands) to 40% ( clays holding a great deal of moisture). Typical values are 10 3 3.2 to 15% with over 20% moisture considered high. • pH -Acidic soils and groundwater are more conducive to galvanic corrosion of ferrous materials than alkaline soils and· groundwater. • Conductivity -For a giv·en corrosion cell wit:p a fixed potential difference between the anode and cathode, the · higher the conductivity, the greater the metal loss. Conductivities over 350 microhmos/cm ( equivalent to a resistivity of2850 ohm-cm) are considered high. • Sulfide Concentration -Any detectable concentrations of sulfide ions are indicative of anaerobic conditions that may support high rates of metal dissolution due to microbiologically influenced corrosion. • Chloride Concentrations -Chloride ions are cathode depolarizers, which enhance the rate of corrosion. The higher the concentration, the greater the rate of corrosion. Many soils have chloride concentrations less than 10 ppm. Concentrations over 50 ppm are significant from a corrosion standpoint. • Soil Resistivity -Resistivity is " a common parameter for evaluating the corrosiveness of the soil. Resistivity is the inverse of conductivity and is measured in units of ohm-centimeters. Corrosivity is often an inverse function of resistivity with low resistivity soils usually more corrosive than high resistivity soils. Resistivity is also related to the concentration of salts with low resistivity indicating high levels of salt. No sources of AC or DC interference were observed during the field survey. Project drawings show, however, that gas lines will be installed in the vicinity of the proposed waterline. DC interference is possible at cathodically protected pipeline crossings. Re-evaluation of DC interference is recommended after gas lines are installed. CORROSION PROTECTION REQUIREMENTS An analysis of the field data obtained during the survey and of the types of proposed pipe materials was made to determine the requirements for and types of cathodic protection that could be considered for the 24" diameter waterline. The CCP and the DIP options are electrically discontinuous along their length because of the dielectric sealing materials used at each pipe joint. Joint bonding is, therefore, required to establish and maintain electrical continuity. Joint bonding is also required for the dielectrically coated steel pipe option at all non- welded (mechanical) joint locations. The high pH of the mortar coating on the CCP option · provides corrosion protection for the embedded steel components. However, low soil resistivity and 4 moisture may compromise the level of corrosion protection making the steel susceptible to corrosion. Therefore, it is recommended that the CCP option be cathodically protected. The dielectric coating on the carbon steel pipe option is the primary corrosion control mechanism. Corrosion will occur, however, at those areas where there are breaks in the dielectric coating. Therefore, the corrosion protection provided by the dielectric coating must be supplemented with cathodic protection. The annealing oxide and asphaltic shop coating typically present on the ductile iron pipe surface are the primary barriers against corrosion. Polyethylene encasement should be used to supplement the corrosion protection provided by the annealing oxide and asphaltic shop coat throughout the length of the DIP option. Additional recommendations include joint bonding and the installation of a galvanic anode cathodic protection system to increase the effective service life of this pipe option. In summary, it is recommended that cathodic protection be installed on the entire length of the proposed waterline alignment regardless of the selected pipe material. In addition to the installation of cathodic protection, electrical continuity bonds must be installed on all buried mechanical joints for the CCP, the steel pipe and the DIP .options. A polyethylene encasement should also be installed on the entire length of the DIP option. It is necessary to electrically isolate the waterline at all tie-ins to other buried metallic pipelines. In addition, where the pipe may pass through casings the carrier pipe in the casings must be electrically isolated from the steel casing. Monitoring test stations should be installed at galvanic anode ground bed locations, cased crossings and at all buried underground in-line pipeline isolation fittings. 4.0 CORROSION PROTECTION DESIGN REPORT 4.1 SUMMARY The proposed water pipeline will be offered based with the following alternative configurations: • Bar-wrapped concrete cylinder pipe (A WW A C303): A corrosion control system consisting galvanic anode cathodic protection, joint continuity bonds and monitoring test stations with joint isolation at connections to existing pipelines is recommended for this pipeline configuration. 5 • . Dielectrically coated carbon steel pipe: A corrosion control system consisting of galvanic anode cathodic protection, joint continuity bonds for all non- welded mechanical joints, monitoring test stations, joint isolation at connections to existing pipelines and electrical isolation at cased crossings is recommended for this pipeline configuration. • Ductile iron pipe: A corrosion control system consisting of polyethylene encasement throughout the pipe length, electrical continuity joint bonds, cathodic protection, monitoring test stations, joint isolation at connections to existing pipelines and electrical isolation at cased crossings is recommended for this pipeline configuration. 4.2 PROTECTIVE COATINGS The mortar coating on the CCP option provides a high pH environment, which is protective of the steel embeddments . The mortar coating should be applied in accordance with A WW A Standards to make certain that it is of low porosity and low permeability. The pipe should be handled without cracking the mortar and the joints must be properly diapered. It is recommended that a polyurethane coating system be used to prevent corrosion of the external surfaces of the · carbon steel pipe option. The polyurethane coating shall be in accordance with the ANSI/ A WW A C222 Standard. All welded and/or mechanical joints should be coated with heat shrink sleeves. Proper installation of the heat shrink sleeve must be assured to prevent any delamination between the coated pipe and the sleeve. The ductile iron pipe option shall be protected with polyethylene encasement throughout it length in accordance with the AWWA C-105/A21.5 standard. A high-density, cross-laminated polyethylene film is recommended for this application. 4.3 PIPE BEDDING & BACKFILL There may be places along the pipeline right-of-way where the pipe will be installed in rocky areas. It is essential that the pipe be provided with proper bedding to prevent physical damage to the pipe, mortar and/or dielectric coating. It is recommended that bedding materials such as clean river sand be used for this purpose. Backfill material should also be finely graded to prevent damage to . either the dielectric or mortar coating. 4.4 CATHODIC PROTECTION The recommended galvanic anode cathodic protection system for any of the pipe material options shall include three (3) groundbeds, each consisting of twelve 20- pound prepackaged magnesium anodes, installed vertically at a depth of 15 feet, 6 and spaced 12 feet (center-to-center). The anode groundbeds shall be installed at pipe stations 3+75, 11+00, and 21+66. The CCP option requires two (2) welded steel clips across all mechanical pipeline joints to establish and maintain electrical continuity. The DIP option requires two bonding cables welded across each joint to ensure electrical continuity. The dielectrically coated steel pipe option requires two bonding wires across all non- welded mechanical joints. Refer to Appendix E, Specification for galvanic anode cathodic protection systems. 4.5 JOINT BONDING AND ELECTRICAL ISOLATION The 24" diameter waterline should be electrically isolated from existing mains and laterals. Installation of bonding clips or bonding cables across all mechanical joints is r~quired for the CCP and DIP options. The dielectrically coated steel pipe option requires two bonding wires across all non-welded mechanical joints. Refer to Appendix C, Joint Bonding and Electrical Isolation. 4.6 TEST STATIONS Test stations will allow periodic monitoring of the effectiveness of the cathodic protection system on the CCP, carbon steel and DIP options. They will also allow future monitoring of possible DC interference voltages on the three pipe alternatives. Test stations are required for all pipe materials at cathodically protected foreign line crossings, galvanic anode ground bed locations and buried underground electrical pipeline isolation joints. Test Station types are as follows: 1. TS -Standard pipe-to-soil potential measurement test station at groundbed locations. See details on the cathodic protection drawings. 2. CP -Test station installed at the ends of metallic pipeline casings with lead wires to the pipeline and lead wires to the casing (see Tunnel or Cased Crossing Test Station detail on the cathodic protection drawings). CP test stations shall be installed at both ends of all metallic casings. 3. FL -Test station installed at crossing of underground steel piping systems owned by others (foreign pipelines). See FL type test station on 7 the cathodic protection drawings. In addition to the lead wires to be installed for the pipeline and the foreign pipelines, bond wires shall also be installe,d, one to the water transmission pipeline and one to the foreign pipeline: The bond wires shall be No. 8 AWG, single conductor, stranded, . . copper. wire with TW or THHN insulation. The insulation shall be white in color for bond wires installed on the water transmission pipeline and red in color for bond Wires installed on foreign pipelines. 4. IF -Test station installed across buried isolation joints. See IF type test ·station on the cathodic protection drawings.

The installation of galvanic anodes for any of the pipe material options will provide the means for external corrosion control. . . . 4.7.2 The waterline should be electrically isolated from existing metallic transmission mains and laterals. · 4.7.3 Installation of bonding clips or bonding cables across all joints is required for the CCP and DIP options. The dielectrically coated steel pipe option requires two bonding wires across all mechanical (non-welded) joints. 4.7.4 Installation of a polyethylene encasement is recommended for the DIP option. 4.7.5 Proper monitoring of the cathodic protection system will be achieved through test stations installed at cased crossings, foreign pipeline crossings, galvanic anode ground beds locations and buried underground electrical isolation fittings. In addition, permanent reference cells will assist in monitoring of pipe-to-soil potential measurements at ground bed locations. Monitoring test stations are recommended for all three pipe material alternatives. 10 ..

Circulate current through pipe using DC power supply. Calculate resistance through known length of pipe. Resistance must not exceed 150% of theoretical resistance for pipe and bonds. 2. Measure resistance through select bonded joints with a digital fow resistance ohmmeter (DLRO). Resistance of 0.001 ohms or less is acceptable. 3. Position a copper sulfate electrode (CSE) at a stationary location adjacent to bonded pipeline. Impress a temporary current on pipe. Record the stati~, current- applied, and "instant off' pipe-to-soil potential measurements along the pipe relative to a stationary CSE. a. Static potential measurements referenced to a stationary CSE must be nearly identical along the pipe to indicate electrical continuity. b. "Instant off' potentials referenced to a stationary CSE must be nearly identical along pipe to indicate electrical continuity. c. The difference between the "instant off' and the static potential referenced to stationary CSE must be equal at each point of contact to pipe to indicate electrical continuity. 4.

A DC current shall be impressed on the pipe on one side of the joint under test using a portable 12-volt battery and a driven ground rod. The battery shall be connected such that the positive terminal is connected to the ground rod and the negative terminal is connected to the pipe section under test. The magnitude of test current is not important as long as it causes a change in pipe-to-soil potential on the section of pipe that is in the test current circuit. C. The pipe-to soil potential shall be measured on each side of the isolation joint using a high impedance voltmeter and portable copper/copper sulfate reference electrode with the test current "on" and "off'. · D. A joint is considered electrically continuous if the "on" and "off' potentials are the same on either side of the joint under test. E. This same procedure shall be used to test individual isolation joints except that the joint is considered effective if the pipe-to-soil potential is not the same when measured on each side of the joint when the test current is "on". 3.04 INSTALLATION OF CASING SPACERS A. Assemble and securely fasten casing spacers to the pipeline to be installed in casings or tunnels. B. A void inadvertent metallic contact between casing and carrier pipe.

The end spacer must be within 6 inches of the end of the casing pipe, regarµless of size of casing and pipe or type of spacer used . Install spacers on PVC pipe at the insertion line to prevent over-insertion of the spigot into the bell. C . Grade the bottom of the trench adjacent to each end of the casing to provide a firm, uniform and continuous support for the pipe. If the trench requires some backfill to establish the final trench bottom grade, place the backfill material in 6-inch lifts and compact each layer. May,2008 15640 Page 8 of9 WATER AND SANITARY SEWER MAIN RELOCATIONS JOINT BONDING AND FOR SH-121T (SOUTHWEST PARKWAY) ELECTRICAL ISOLATION D.

Tubular Type (Method A): 1. Cut polyethylene tube to a length approximately 2 feet longer than pipe section. Slip tube around pipe, centering tube to provide 1-foot overlap on each adjacent pipe section. Bunch accordion-fashion lengthwise until it clears pipe ends. 2. Make shallow bell hole at joints to facilitate installation of polyethylene tube completely around pipe. Lower pipe into trench and make up pipe joint with preceding section of pipe. Methods other than bell holes shall be allowed, provided the polyethylene tube completely encases the pipe joints, including a minimum overlap of I-foot. 3. After assembling pipe joint, make overlap of polyethylene tube. Pull bunched polyethylene from preceding length of pipe, slip it over end of adjoining length of pipe, and secure in place. Then slip end of polyethylene from adjoining pipe section over end of first wrap until it overlaps joint at end of preceding length of pipe. Secure overlap in place. 4. For each pipe length, take up slack width at top of pipe to make a snug, but not tight, fit along barrel of pipe, securing fold with tape at quarter points. A void a tight fit to prevent stretching the polyethylene where it bridges irregular surfaces, such _ as bell and spigot joints, restrained and bolted joints, and fittings; and to prevent damage to film during backfilling. The length of tape to secure wrap shall be no less than 1-foot. 5. Repair cuts, tears, punctures, or other damage to polyethylene. Proceed with installation of next section of pipe in same manner.

Cut polyethylene tube to a length approximately 1 foot shorter than pipe section. Slip tube around pipe, centering it to provide 6 inches of bare pipe at each end. Take up slack width at top of pipe to make a snug, but not tight, fit along barrel of pipe, securing fold at quarter points; secure ends. 2. Make shallow bell hole at joints to facilitate installation of polyethylene tube completely around pipe. Lower pipe into trench. and make up pipe joint with preceding section of pipe. Methods other than bell holes shall be allowed, provided the polyethylene tube completely encases the pipe joints, including a minimum overlap of 1-foot. 3. Take up slack width at top of pipe to make a snug, but not tight, fit along barrel of pipe, securing fold with tape at quarter points. A void a tight fit to prevent stretching the polyethylene where it bridges irregular surfaces, such as bell and spigot joints, restrained and bolted joints, and fittings; and to prevent damage to film during backfilling. The length of tape to secure wrap shall be no less than 1-foot. 4. Before making up joint, slip 4-foot length of polyethylene tube over end of preceding pipe section, bunching in accordion-fashion lengthwise. After completing joint, pull 4-foot length of polyethylene over joint, overlapping polyethylene previously placed on each adjacent section of pipe by _at least 1 foot; make each end snug and secure. 5. Repair cuts, tears, punctures, or other damage to polyethylene. Proceed with installation of next section of pipe in same manner. C. Sheet Type (Method C)-Applicable to Valves, Tees, Elbows and Other Fittings Only: 1. Cut polyethylene sheet to a length approximately 2 feet longer than pipe section. Center length to provide 1-foot overlap on each adjacent pipe section, bunching sheet until it c~ears pipe ends. Wrap polyethylene around pipe so that sheet circumferentially overlaps top quadrant of pipe. Secure cut edge of polyethylene sheet at intervals of approximately 3 feet. 2. Lower wrapped pipe into trench and make up pipe joint with preceding section of pipe. Make shallow bell hole at joints to facilitate installation of polyethylene . After completing joint, make overlap and secure ends. 3. Repair cuts, tears, punctures, or other damage to polyethylene. Proceed with installation of next section of pipe in same manner. ~ay,2008 15643 Page 6 of8 WATE~ AND SANITARY SEWER MAIN RELOC. POLYETHYLENE ENCASEMENT FOR SH-121 T (SOUTHWEST PARKWAY) FOR DUCTILE IRON PIPE D. Installation in Directional Drilled Bore: 1. Install as described in 3.02A. Tubular Type (Method A) with the exception that the polyethylene encasement overlap must face away from the pull direction to avoid the under film accumulation of drilling mud and other foreign matter. 2. Attach pulling head to spigot end of the leading pipe length. 3. Securely anchor the polyethylene tube to the end of the barrel of the leading pipe length by continuously taping the leading two feet of the barrel with overlapping tape wrap. Anchor the first wraps of tape directly on to the barrel of the pipe and extend the continuous taping on to the polyethylene encasement. For the remainder of the leading pipe length, overlap circumferential wraps of tape every one foot. . 4. The drilling fluid and cuttings shall not enter under the polyethylene tube during the pull back or other operations. At assembled joints, the polyethylene overlap shall always have the forward pipe's polyethylene tube overlap the next following pipe's tube. The polyethylene on both sides of the joint shall be secured with circumferential wraps of tape or plastic tie straps. 5. Continue process by wrapping tape on each side of successive joints and every two feet along barrel. E. Pipe-shaped Appurtenances: Cover bends, reducers, offsets, and other pipe-shaped appurtenances with polyethylene in same manner as pipe. F. Odd-shaped Appurtenances: When it is not practical to wrap valves, tees, crosses, and other odd-shaped pieces in tube, wrap with flat sheet or split length of polyethylene tube by passing sheet around appurtenance and encasing it. Make seams by bringing edges together, folding over twice, and taping down. Tape the polyethylene encasement securely in place at valve stem and other penetrations. G. Openings in Encasement: Create openings for branches, saddles, service taps, blowoffs, air valves, and similar appurtenances by making an X-shaped cut in polyethylene and temporarily folding back film. After appurtenance is installed, tape slack securely to appurtenance and repair cut, as well as other damaged area in polyethylene, with tape. H. Hydrant Drain Relief: For hydrant relief holes and similar orifices, apply 3 wraps of tape completely around the polyethylene encased pipe, then, with a utility knife, cut a hole in the tape and polyethylene that is I-inch larger in diameter than the orifice/opening. I. Direct Service Taps: For direct service taps, apply 3 wraps of tape completely around the polyethylene encased pipe to cover the area where the tapping machine and chain will be mounted. After the tapping machine is mounted, install the corporation stop directly May, 2008 15643 Page 7 of8 WATER AND SANITARY SEWER MAIN RELOC.
