When the date of completion is based on a calendar day bid, a request for extension of time because of inclement weather will not be considered. A request for extension of time due to inability to obtain supplies and materials will be considered only when a review of the Contractor's purchase order dates and other pertinent data as requested by the Engineer indicates that tbe Contractor has made a bonafide attempt to secure delivery on schedule. This shall include efforts to obtain the supplies and materials from alternate sources in case the first source cannot make delivery. If satisfactory execution and completion of the contract should require work and materials in greater amounts o r quantities than those set forth in the approved Contract Documents, then the contract time may be increased by Change Order. C7-7.9 DELAYS: The Contractor shall receive no compensation for delays or hindrances to the work, except when direct and unavoidable extra cost to the Contractor is caused by the failure cif the City to provide information or material, if C7-7 (4) any, which is to be furnished b y the City. When such extra compensation is claimed a written statement thereof shall be presented by the Contractor _ to the Engineer and if by him found correct shall be approved and referred by him to the Council for final approval or disapproval; and the action thereon by the Council shall be final and binding. If delay is caused by specific orders given by the Engineers to stop work, or by the performance of extra work, or by the failure of the City to provide material or necessary instructions for carrying on the work, then such delay will entitle the Contractor to an equivalent extension of time , his application for which shall, however, be subject to the approval of the City Council; and no such extension of time shall release the contractor or the surety on his performance bond from all his obligations hereunder which shall remain in full force until the discharge of the contract.

The number of days indicated shall be a realistic est i mate of the time required to complete the work covered by the specific contract being bid upon. The amount of t i me so stated by the successful bidder or the City will become the time of completion specified in the Contract Documents. For each calendar day that any work shall remain uncompleted after the time specified in the Contract Documents , or the increased time granted b j the Owner, or as automatically increased by additional work or materials ordered after the contract is signed, the sum per day given in the following schedule, unless ot h erwise specified in o ther parts of the Contract Docu ments , will be ded u cted f rom monies due the Co n tractor , not as a penalty , b u t as li qui da t ed d amages s u ffered b y th e Owne r .

Such reimbursement shall be based on actual cost to the Contractor of moving the equipment and no profit will be allowed. No reimbu r sement shall be allowed if the equipment is moved to another construction project for the City of Fort Worth. The Contractor shall not suspend work without written notice from the Enginee r and shall proceed with the work operations promptly when notified by the Engi~eer to so resume operations.

This specification will establish procedures to be used by all Excavators in the removal and disposal of asbestos cement pipe (ACP) in compliance with NESHAP. Nothing in this specification shall be construed to void any provision of a contract or other law, ordinance, regulation or policy whose requirements are more stringent. B. 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 responsible to employ those means, methods , techn iques 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 .

By this method an approximate 2-inch hale shall be bored the entire length of the crossing and shall be checked for line and grade on the opposite end of the bore from the work pit. This pilot hole shall serve as the centerline of the larger diameter hole to be bored. Other methods of maintaining line and grade on the casing may be approved if acceptable to the Engineer. Excavated material shall be placed near the top of the working pit and disposed of as required. The use of water or other fluids in connection with the boring operation will be permitted only to the extent required to lubricate cuttings. Jetting or sluicing will not be permitted. b. In unconsolidated sofl formations. a gel-forming colloidal drilling fluid consisting of at least 10 percent 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, Allowable variation from the line and grade shall be as specified under paragraph A.2. All voids between bore and outside of casing shall be pressure grouted. 4 . Installation of Carrier Pipe in Casing : a. Sanitary sewer pipe located within the encasement pipe shall be supported by "skids" or "bands" to prevent the pipe and bells from snagging on the inside of the casing, and to keep the installed line from resting on the bells. ASC-5 10115107 PART DA -ADDITIONAL SPECIAL CONDITIONS b. All skids shall be treated with a woad preservative. Skids should extend for the full length of the pipe with the exception of the bell area and spigot area necessary for assembly unless otherwise specified. c. The Contractor shall prevent over-belling the pipe while installing it through the casing . A method of restricting the movement between the assembled bell and spigot where applicable shall be provided. d. At all bared, jacked, or tunneled installations, the annular space between the carrier pipe and casing shall be filled with grout. Care must be taken that not too much water is forced into the casing so as not to float the pipe. The backfill material will not be required unless specified on the plans and specified by the Engineer. e. Closure of the casing after the pipe has been installed shall be plugged at the ends of the casing as shown on the drawings or as required by the Engineer. 5. Boring and Jacking Ductile Iron Pipe without Casing Pipe: a. As indicated an drawings and as required and directed by the Engineer sewer shall be constructed of bore and jacked ductile iron pipe. b. When a casing pipe is not designated on the drawings, the contractor shall provide a casing pipe if necessary to achieve line and grade. Casing pipe shall be provided at no additional cast and shall be subsidiary to the cost bid for installation By Other than Open Cut. c. Bore and jack in accordance with paragraph C.3. above. d. Short length of sewer consisting of a single pipe section may be installed by jacking without a bore hale if permitted by the Engineer and in soft soil layer. All voids outside of installed pipe shall be pressure grouted. 6 . Tunneling: Where the characteristics of the soil , the size of the proposed pipe, or the use of monolithic sewer would make the use of tunneling more satisfactory than jacking or boring, or when shown on the plans , a tunneling method may be used, with the approval of the Engineer or railroadlhighway officials. a. b. When tunneling is permitted, the lining of the tunnel shall be of sufficient strength of support the overburden. The Contracto r shall submit the proposed liner method to the Engineer far approva l. The tunnel liner design shall bear the seal of a licensed professional engineer in the State of Texas. Approval by the Engineer shall not relieve the Contractor of the responsibility for the adequacy of the liner method. Th e space between the tunnel liner and the limits of excavation shall be pressure grouted or mud-jacked. ASC-6 - - - - D. PART DA -ADDITIONAL SPECIAL CONDITIONS c. Access holes for placing concrete shall be space at maximum intervals of 10 feet. MEASUREMENT AND PAYMENT: Installation of pipe by other than open cut will be measured by the linear foot of pipe, complete in place.

The borings were drilled to total depths of 60 f eet utilizing hollow stem augers and wet rotary drilling methods. Continuous coring w as performed at selected interva ls within the rock and rock-like materials using an NW (formerly NX) size, double-tube core barrel. The attached boring logs presented herein contai n the results of th e field investigation and laboratory testing f or the project. Additiona l information concerning subsurface exploration and laboratory methods and procedures are available upon request. Elevations of each boring were estimated from TranSystems Corporation drawing "Sh eet W1 " dated November 2006 . Phone (817) 284 -9400 Fax (817) 589-9993 Metro (817) 589-9992 CMJ ENGINEERING, I N C. TranSystems Corporation CMJ Project 123-06-05 December 21 , 2006 Page 2 of 3 Overburden materials encountered within the borings consist of various dark brown , brown, and light brown silty clays , sandy clays , silty sandy clays , shaly sandy clays , and clays . Below depths of 18.5 to 19 feet , sands , sandy clays , and clayey sands were encountered in the borings at selected depths, and contained gravel and other alluvia l materials . The sands were medium dense, with Standard Penetrat ion (N) value of 13 to 25 blows per foot of penetration. Gray limestone was next present in the borings at depths of 23 to 42 feet. The correspond ing elevation of the gray limestone is approximately El. 551 and 531 in Borings B-1 and B-2, respectively. The gray limestone contains shale seams and layers up to 1.5 feet in thickness, and was hard to very hard , with exhibited Texas Cone Penetrometer (THO) values ranging from 1 to 1.5 inches per 100 blows . Dark gray shale was present w it hin t he gray limestone in Boring B-1 from 37 to 44 feet below existing grade. Rock quality designation (RQD) measurements of recovered core samples range from 35 to 73 percent with an average RQD value of approxi mately 50 percent , indicat ing fair rock qual ity or generally moderately fractured in-situ rock . Laboratory testing of gray limestone samples in unconfined compression testing resulted in strength values of 265 ,500 and 297 ,500 psf . These values are considered moderately high strength values from the viewpoi nt of rock strength. Unconfined compress ion test ing of the dark gray shale st rata and layers resu lted in a tested strength value of 49,200 psf, ind icating low to moderate strength value (sedimentary rock basis ). The proposed tunnel bore crossing beneath the river should be situated a sufficient depth beneath the tha lweg of the Trinity River to provide adequate tunnel support , rock cover , and excavation stability during construction . The hard to very hard gray li mestone was enco untered in Bo rin gs 8-1 and 8-2 at Elevat ion 53 1 to 55 1.

CMJ ENGINEERING, INC. TranSystems Corporation CMJ Project 123-06-05 December 21, 2006 Page 3 of 3 Readers should understand that the Trinity River has carved out original ground and caused the top of gray hard to very hard limestone to occur at varying elevations . The above recommendations call for a minimum 10-foot cover of this limestone above tunnel bores . No guarantee exists that the top of gray hard to very hard limestone does not dip downward below Elevation 522 due to eroded , isolated shale zones. This recommendation, in our opinion , provides a reasonable probability, assuming a 10-foot cover of limestone is maintained.

The proposed 48" diameter pipeline has an approximate length of 2 ,328 feet. The proposed 42" diameter pipeline has an approximate length of 1,432 feet. The proposed 36" diameter pipeline has an approximate length of 139 feet. All sections of the proposed Hulen to Como water pipeline will be offered for bid with the following material alternatives: • Bar-wrapped concrete cylinder pipe (A WW A-C303). • Coated carbon steel pipe. • Ductile iron 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 corrosive to the three metallic pipe materials being considered -concrete cylinder pipe (CCP), dielectrically coated steel pipe and ductile iron pipe (DIP). Corrosion protection measures are recommended for all of these materials to preserve the physical integrity of the pipe. 2.2. The mortar coating on the CCP provides corrosion protection for the embedded steel components. 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 CCP option be cathodically protected. 2.3. The installation of a cathodic protection system is recommended for the dielectrically coated steel option to minimize the probability of corrosion at coating holidays. In summary, it is recommended that cathodic protection be installed on the entire length of the CCP and the carbon steel pipe material options. For the DIP option it is also recommended that cathodic protection be installed on the Line A section only. In addition to the installation of cathodic protection, electrical continuity bonds must be installed on all buried mechanical joints on the CCP option. A polyethylene encasement should be installed on the entire length of the DIP option with electrical continuity bonds and cathodic protection for the Line A section only. It is necessary to electrically isolate the City of Fort Worth Hulen to Como CCP and carbon steel pipe and DIP options at all tie -ins to other buried metallic pipelines regardless of the type of metallic pipe material. In addition, for all three pipe material options, where the pipe passes through casings, the carrier pipe in the casings must be electrically isolated from the steel casing. Monitoring test stations should be installed for the pipeline at foreign line crossings, cased crossings, major road crossings, galvanic anode ground bed locations, corrosion probe locations and at all underground in-line pipeline isolators. 4.0 CORROSION PROTECTION DESIGN REPORT 4.1 SUMMARY The proposed water pipeline will be offered based on the following alternative configurations: • Bar-wrapped concrete cylinder pipe (A WW A C303): A corrosion control system consisting of galvanic anode cathodic protection, joint continuity bonds, monitoring test stations and joint isolation at connections to existing pipelines is recommended for this pipeline configuration. • Dielectrically coated carbon steel pipe: A corrosion control system consisting of galvanic anode cathodic protection, joint continuity bonds for all non-welded 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 its length with electrical continuity joint bonds and cathodic protection to be installed on the Line A section only. Monitoring test stations and joint isolation at connections to existing pipelines, with electrical isolation of the Line A section . Electrical isolation at cased crossings is also 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. A polyurethane coating system shall be used to prevent corrosion of the external surfaces of the steel pipe. 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 external surfaces of 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 the CCP option considered for this project shall include ten (10) galvanic anode groundbeds each consisting of ten, 20-pound prepackaged elongated magnesium anodes. Refer to enclosed drawings for locations . The recommended galvanic anode cathodic protection system for the Dielectrically Coated Steel Pipe option considered for this project shall include eight (8) galvanic anode ground beds each consisting of ten, 20- pound prepackaged elongated magnesium anodes. Refer to enclosed drawings for locations. 2 The recommended galvanic anode cathodic protection system for the Line A section of the DIP option considered for this project shall include two (2) galvanic anode ground beds each consisting of ten, 20-pound prepackage elongated magnesium anodes. Refer to enclosed drawings for locations. In addition, the CCP option will require two bonding clips welded across each joint to ensure electrical continuity of this pipeline option. The DIP option requires two bonding cables welded across each joint of the Line A section to ensure electrical continuity of this section of the pipeline. 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 City of Fort Worth Hulen to Como Water Line CCP and carbon steel options should be electrically isolated from existing metallic transmission mains and laterals. Bonding of non-welded joints is required for the three pipe material alternates being considered. Bond cables should be thermite welded across all non-welded steel pipe joints and across ductile iron pipe joints for the Line A section only. Steel clips should be welded across all CCP joints except when the joints are restrained by welding. 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. Test stations are required for all pipe materials at cased crossings, foreign line crossings, major highway crossings, galvanic anode ground bed locations, corrosion rate probe locations and 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 TS type test station on the cathodic protection drawings. 2. CC -Test station installed at the ends of metallic pipeline casings with 2 lead wires to the pipeline and 2 lead wires to the casing . See CC type test station on the cathodic protection drawings. CC 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 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 installed, one to the water transmission pipeline and one to the foreign pipeline. The bond wires shall be No. 8 A WG, single conductor, stranded, copper wire with TW or TIDIN 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. 5. CP -Test station installed at corrosion rate probe locations. See CP type test station on the cathodic protection drawings. Note: Lead wires and bond wires are to be installed on foreign pipelines (if any) by the foreign pipeline owners. The City of Fort Worth will make arrangements with the foreign pipeline owners (if any) for installation of lead wires and bond wires on the foreign pipelines. Contractor SHALL NOT install lead wires or bond wires on foreign pipelines. 4.7 CONCLUSIONS AND RECOMMENDATIONS 4.7.1. The installation of galvanic anodes for the CCP, carbon steel and the DIP Line A options along the pipeline alignment will provide the means for external corrosion control of these waterline options. 4.7.2 The CCP and carbon steel and DIP options should be electrically isolated from existing metallic transmission mains and laterals . 4.7.3 Joint bonding of the CCP option is required to maintain the electrical continuity throughout this pipe option. Joint bonding of the Line A section of the DIP option is required for this pipe option. For the dielectrically coated steel pipe option joint bonding is also required at all non-welded mechanical connections. 4. 7.4 Proper monitoring of the cathodic protection system will be achieved through test stations installed at cased crossings and buried isolation fittings. In addition, permanent reference cells will assist monitoring of pipe-to-soil potential measurements at ground bed locations and corrosion probe locations.

C. Thermite Welding Methods: Perform thermite welding of bond wires and bond straps to piping in the following manner: 1. Clean and dry pipe to which wires or straps are to be attached. 2. Use grinding wheel to remove all coating, mill scale, oxide, grease, and dirt from an area approximately 3 inches square. Grind surface to bright metal. 3. Remove approximately 1 inch of insulation from each end of wire to be thermite welded to pipe, exposing clean, oxide-free copper for welding. 4. Select proper size thermite weld mold as recommended by manufacturer. Place wire or strap between graphite mold and the prepared metal surface. 5. Place metal disk in bottom of mold. 6. Pour thermite weld charge into the mold. Squeeze bottom of cartridge to spread ignition powder over charge. 7. Close mold cover and ignite starting powder with flint gun. 8. After exothermic reaction, remove thermite weld mold and gently strike weld with a hammer to remove weld slag. Pull on wire or strap to assure a secure connection. If weld is not secure or the bond breaks, repeat procedure with new wire or strap. 9. If weld is secure, coat all bare metal and weld metal with Kop-Coat. Cover coated weld with a plastic weld cap. October, 2006 15640 Page 6 of9 CITY OF FORT WORTH JOINT BONDING AND ELECTRICAL ISOLATION HULEN TO COMO WATERLINE D. Post-Installation Inspection: Post-installation inspection of all electrical continuity bonds shall be made through a visual examination of each thermite weld connection for strength and suitable coating prior to backfilling. In addition, perform one or more of the following tests: 1. 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 Jomts with a digital low resistance ohmmeter (DLRO). Resistance of 0 .001 ohms or less is acceptable. 3. Position a CSE at a stationary location adjacent to bonded pipeline. Impress a temporary current on pipe . Record static, current-applied, and "instant off' pipe-to-soil potential measurements along the pipe relative to the stationary CSE. a. Static potential measurements referenced to stationary CSE must be nearly identical along the pipe to indicate electrical continuity. b. "Instant off' potentials referenced to 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. If any of the above procedures indicates a poor quality bond connection, reinstall the bond. 5. Record results and submit to the owner or its designated representative for approval prior to backfilling. E. Backfilling of Bonded Joints: 1. Perform backfilling of bonded piping in manner that prevents damage to the bonds and all connections to the metallic structures. a. Use appropriate backfill material to completely cov er the electrical bond. b . Prov ide protection so that future construction ac tiv ities in the area will not destroy the bonded connections. 2. If construction activity damages a bonded connection, install new bond wire. October, 2006 15640 Page 7 of9 CITY OF FORT WORTH HULEN TO COMO WATERLINE JOINT BONDING AND ELECTRICAL ISOLATION 3.02 INSTALLATION OF PIPELINE FLANGE ISOLATION DEVICES A.

Painting: Do not use metal base paints on insulating fittings. E. Encapsulation: Encapsulate below-grade isolation joints with the Carboline Densyl tape system, or approved equal, after the isolation joint has been tested for effectiveness. 3.03 TESTING OF JOINT CONTINUITY BONDS AND ISOLATION JOINTS A. General: After the completion of the continuity bonding of individual joints but before the pipe is backfilled, each bonded joint shall be tested for electrical continuity. B. 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 inst alled in casings or tunnels. October, 2006 15640 Page 8 of9 CITY OF FORT WORTH HULEN TO COMO WATERLINE JOINT BONDING AND ELECTRICAL ISOLATION B. A void inadvertent metallic contact between casing and ca.mer pipe. Place spacers close enough to ensure that the pipe is adequately supported throughout its length, particularly at the ends, to offset settling and possible electrical shorting. The end spacer must be within 6 inches of the end of the casing pipe, regardless 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. D. After the casing or tunnel liner has been placed, pump dry and maintain dry until the casing spacers and end seals are installed. E. Install casing spacers in accordance with the manufacturer's instructions. Correctly assemble, evenly tighten, and prevent damage during tightening of the insulators and pipe insertion . F. Insulator Spacing: 1. Maximum distance between spacers to be 10 feet for pipe sizes 6 inches and smaller, and 6 feet for pipe sizes greater than 6 inches. 2. For ductile-iron pipe, flanged pipe, or bell and spigot pipe, install spacers within one foot on each side of the bell or flange, and one in the center of the joint where 18 foot or 20 foot long joints are used. 3. If the casing or pipe is angled or bent, reduce the spacing. 3.05 INSTALLATION OF END SEALS A. Assemble hard rubber Link-Seals around the pipe and slide into the annular space between the pipe and casing. Evenly tighten the bolts to provide a positive seal. B . Place pull -on synthetic rubber end seals on the pipe and pull over the end of the casing. Securely fasten stainless steel bands. 3.06 CASED CROSSING IS OLATION TESTS A. Immediately after the pipe has been installed in the casing, but prior to connecting the line, perform an electrical continuity test to determine that the casing is electrically isolated from the pipeline. The continuity check shall be fully documented and approv ed by the owner or its designated representative prior to backfilling. B. If the electrical isolation between pipe and casing is not effectiv e, the cause shall be immediately investigat ed , and the situation remedied. Under no circumstances shall a shorted casing be b ackfilled.

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 1-foot. 3. After assembling pipe joint, make overlap of polyethylene tube. Pull bunched polyethylene from preceding length of pipe, slip it ov er 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 v oid a tight fit to prevent stretching the polyethylene where it bridges irregular surfaces, such as bell October, 2006 15643 Page 5 of8 CITY OF FORT WORTH HULEN TO COMO WATERLINE POLYETHYLENE ENCASEMENT FOR DUCTILE IRON PIPE 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. B. Tubular Type (Method B) 1. 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. Avoid 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.

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 polyethylene 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.

END OF SECTION October, 2006 15643 Page 8 of8 Pamphlet No.1150-2-1 DEPARTMENT OF THE ARMY U.S Army Corps of Engineers, Fort Worth District P.O. Box 17300 Fort Worth, Texas 76102-0300 Local Cooperation CRITERIA FOR CONSTRUCTION WITHIN THE LIMITS OF EXISTING FEDERAL FLOOD PROTECTION PROJECTS SWFP 1150-2-1 31 October 2003 1. Pamphlet Purpose. This pamphlet provides guidance to individuals , developers, architect-engineering firms, local project sponsors, and local governmental agencies for the construction of new facilities or the modification of existing facilities within the limits of an existing Federal flood protection project constructed by the U.S . Army Corps of Engineers, Fort Worth District (CESWF) and for which local project sponsors and/or local governmental agencies have the responsibilities for operation and maintenance. The CESWF, in accordance with Title 33 CFR, Section 208.10, retains the right of review and approval on all proposed improvements and/or modifications that are passed over, under, or through the walls, levees, improved channels, or floodways of such projects. The guidance contained in this pamphlet applies to the activities described herein in most cases; however CESWF reserves the right to reconsider this guidance at any time due to unknown or unforeseen circumstances, technological advances, additional information, etc . 2 . Applicability. This pamphlet applies to all Federal flood protection projects constructed by CESWF, and for which a letter of assurance agreeing to the operation and maintenance of the flood protection project has been furnished CESWF by the project 's local sponsor. 3. Project Purpose. A Federal flood control project is designed to safely carry floodwater within the project and through a developed area. As such , any proposed developments within the project must keep the safe passage of floodwater as the first priority . The roles of the CESWF and the project local sponsor are to maintain the integrity of the project while preventing negative impacts to the passage of the project design flood. The CESWF will not allow the safety of the project to be compromised or the required design carrying capacity of the project reduced . 4. General Criteria for Construction Within a Floodway. a . As early as possible during the planning process , discuss preliminary proposals with the CESWF and the local sponsor to avoid major revisions or project delay. The local sponsor may make any requirements of this Pamphlet more stringent than those contained herein. Concept proposals may be submitted for review. Submit the proposed construction starting date and the detailed project construction schedule, including sequence of construction prior to initiation of work. b. Construction may not start until final written contract drawings and plans have been reviewed and approved in writing by both the CESWF and the local sponsor. c. Furnish five (5) sets of plans and specifications for the proposed work to the CESWF, Operations Division, ATTN: CESWF-OD-M, via the local sponsor sufficiently in advance of proposed construction to a llo w adequate time for review and approval. A vicinity map shall be included in the plans showing the right-of-way boundaries of the flood protection project with specific levee toe and channel slope limits in the portion of the project being crossed, if applicable. This pamphlet supersedes SWFP 1150-2-1 dated 15 October 1985 . d. If boring, jacking, or tunneling operations are planned; detailed designs, calculations, and construction procedures must be provided for review. See subsequent paragraphs for additional details and required procedures. e. Practice approved construction methods and best management practices to minimize erosion at the construction site. All work shall be performed in such a manner as to be as environmentally friendly as possible. This includes making every effort to reduce the turbidity of the water at the site, such as by limiting the amount of time construction equipment is in the water. A storm water pollution prevention plan (SWPPP) must be included in the final project submittal. f. When construction work is in progress in a project located downstream of a Federal dam, a request from the contractor for changes in regulated releases will be considered on individual cases only. Normally, regulated releases from upstream lakes for evacuation of floodwaters, water supply, recreation, or other purposes considered to be in the best interest of the public will have first consideration. A flood event could occur at any time during construction activities and could affect these activities. g . Construction equipment, spoil material, supplies, forms, buildings for inspectors, labs, or equipment and supply storage buildings, etc., shall not be placed or stored in the floodway during construction activities. Any item that may be transported by flood flows shall not be stored within the project. Locations of construction trailers and stockpile areas shall be included on project plans and approved by the CESWF and the local sponsor. h. In addition to other requirements set forth in this Pamphlet, permits may be required under Section 10 and Section 404 for the desired work. These permits require a minimum of 90 days to process. It is recommended that contact with the CESWF Regulatory Branch be initiated in the early planning stages to prevent delays. i. Repair or replace any maintenance and operation roads disturbed during construction to a condition equal to or better than their condition before construction. All roads must be inspected by the local sponsor prior to completion of the project. j. Compact all fill and backfill in 6-inch lifts as specified in job specifications approved by the CESWF. Compaction shall be to at least 95 percent of modified density as specified in ASTM D-1557 . All backfill shall consist of impervious materials. Reestablish vegetation to its original condition or better. Remove all excess material from the limits of the floodway. k. Provide scour protection consisting of articulating revetment system protection capable of being re- vegetated at the outfall of stilling basins designed according to the issuing jet velocity. If approved by the local sponsor, riprap, gabions, or concrete paving may be substituted for the revetments. I. The crown or crest of the levee referred to in this pamphlet is the original or design levee crest elevation. This may or may not be the same as the current levee crest elevation. All modifications shall be based on the higher of the two elevations. m. Upon request, the CESWF Hydrology and Hydraulics Section may provide applicable hydraulic models to be used for design . n. Any permanent disturbance of existing recreation facilities must be mitigated. o. Sump areas adjacent to federa l projects are considered an integral part of the federal project and any modifications to them will be reviewed and approved in accordance with this Pamphlet. SWFP 1150-2-1 2 5. Crossing Over Existing Levees At Grade. a . The local sponsor may decide to not allow any proposed crossing over existing levees at grade. b. No excavation or notching will be performed into or on the levee, or within the levee template. c. Strip topsoil from the levee and place the line up and over the levee template slopes at grade. This will require rather abrupt line grade changes at the levee crest. Cover the new line by placing new fill uniformly on the slopes and top of the levee to slope away from the line and parallel to the longitudinal axis of the levee. Provide a minimum of 2 feet of cover over the new line . The slope of the fill shall be 1 vertical on 20 horizontal or flatter. Replace the topsoil , reestablish grass on all disturbed areas, and restore any roadways . d. All valves located within 15 feet of either side of the projected toe of the levee shall be provided in a concrete box enclosure with a manhole type cover. Valve boxes located within the floodway shall be underground and flush with the surface. If the valve box is placed in the levee crest, the bottom of the excavation shall be not lower than one foot above the design water surface elevation. Fill shall be uniformly placed to slope away from the top of the v alve box. If possible all valves shall be placed on the landside of levees a minimum of 15 feet from the projected levee toe. e. Provide water-tight sealed manhole covers for all manholes w ithin the floodway having tops below design water surface elevation. Fasten manhole covers to the manhole structures. 6. Crossing Under Levees with Open Excavation. a. Provide a temporary ring levee (cofferdam) on the riverside of the existing levee at the location of the subject crossing to the same top elevation as the existing levee . This ring levee shall have a minimum crest width of 10 feet and sides slopes of 1 vertical on 3 horizontal or flatter. Construct the levee of impervious materials according to the provisions specified in Paragraph 4j. b . When the temporary ring levee is complete, excavate through the existing levee using one vertical on three horizontal cut slopes. The toe of the levee and ring levee shall be a minimum of 20 feet (measured horizontally) from the top edge of the excavation . c . Generally, sources for borrow materials shall not be located within the limits of the floodway right-of-ways. In addition, depending on the type of soil and whether or not pervious materials or unstable materials exist in the foundation of the existing levee , it may be desirable to limit the depth of excavation or specify a minimum distance from the land-s ide toe of the levee. All excavated slopes shall be properly designed and the drawings sealed by a registered professional engineer. d. After the line has been placed , the open excavation will be compacted in accordance with Paragraph 4j. When backfill operations are completed, the entire foundation area to be occupied by the replaced levee fill shall be scarified, plowed, and/or harrowed to a depth of 6 inches, and then compacted by at least 16 complete passes of the tamping roller or 95 percent modified density, whichever is more rigorous. e. Accomplish levee replacement by placing fill in 6-inch lifts and compacting by not less than eight complete passes of a tamping roller or at least 95 percent modified density. After compaction, the moisture content shall be within the limits of 3 percentage points abo ve optimum to 2 percentage points below optimum moisture content. SWFP 1150-2-1 3 f. Determine the in-place moisture content and density of the levee fill on a frequency of about one sample for each 2500 cubic yards of backfill placed in the levee. g. When the breached levee has been reconstructed to its original grade, remove the temporary ring levee and dress and turf the surface areas of the plugged section. h. Provide water-tight sealed manhole covers for all manholes within the flood protection project having tops below design water surface elevation. Fasten manhole covers to the manhole structures. i. For pipelines, install a positive cut-off structure to prevent water from the riverside flowing through the pipeline to the landside. If located on the riverside of a levee, extend the cut-off structure to the levee crown elevation by bridge. This structure must be accessible no matter what flood condition may exist. The closure device must be operational by manpower, if necessary. j. Provide gravity storm drains discharging into the floodway with automatic flap gate(s) at the discharge end of the line and energy dissipaters, as required. The owner or local sponsor, as per written agreement, shall be responsible for inspection and maintenance to ensure proper operation of the flap gates. k. Use monolithic conduits or conduits with water-ti ght joints under the levee and levee template. 7. Crossing Under Levees with Boring or Jacking of Sleeves. The sequence of work shall be as follows: a. Excavate the boring and jacking pit (must be on the land side outside the projected toe of the levee template slope). · b. Bore and jack the sleeve to a point beyond the projected riverside toe of the levee template slope. c. If the difference in the diameters of the bore and sleeve exceeds 3 inches, the annular space shall be pressure grouted with bentonite slurry. d. Place the product line in the sleeve. e. Pressure grout the product line in sleeve with bentonite slurry. f. Excavate the pit on the riverside and construct a manhole with gate valve placed on inside face of manhole away from channel. Tie line from sleeve under levee into manhole with gate valve . g. Tie line from sleeve under levee into a manhole on landside. h. During work on items a through h, a plug will be required to be placed and braced at the open end of the sleeve and pipe located in the jacking pit at the close of work each day. This plug must remain in place until the gate valve is installed and connections made to ensure protection from flooding from the river. 8. Horizontal Directional Drilling Under Levees and Channels. a . Detailed contractual drawings , plans , procedures, and engineering calculations shall be pro v ided to CESWF for review. These must include all the requirements of Paragraph 4 above and the following additional items: (I ) Inside diameter of the final bore hole and outside diameter of the product casing. SWFP 1150 -2 -1 4 (2) Detailed description of construction and horizontal boring methods to be utilized. (3) If the difference in the diameters of the final bore and product casing exceeds 3 inches, provide the method of pressure grouting the annular space between the outside of the product casing and the inside of the bore to prevent seepage under the levee template during maximum river stages . (4) A profile of the proposed line showing alignment (including location of the river and levees). (5) Location of entry and exit points, location, elevations and proposed clearances for all utility crossings and structures (6) Right-of-way lines, property, and other utility right-of-way or easement lines (7) Depth under the base of the levee, depth of the line under the river channel, and location of both ends of the string . If the proposed depth of the string directly below the base of the levee is less than 30 feet, then detailed engineering calculations sealed by a registered professional engineer shall be provided for review. These calculations must show a minimum 1.5 factor of safety against hydro -fracturing to be acceptable. b. Develop and provide a quality control plan for the project that includes the maximum allowable drilling pressure, gage calibration method, and responsibility for assuring that the pressure is not exceeded. c. The minimum clearance distance from the top of the pipe encasement to the original design river bottom elevation shall be 7 feet. Should the existing channel bottom elevation be lower than original design grade, the new line shall be the discussed depth below the existing bottom elevation. d. Develop and provide a quality control plan for the project that includes the maximum allowable drilling pressure, gage calibration method, and specific responsibility for assuring that the pressure is not exceeded. During the drilling process, the pressure in the borehole must be monitored to ensure that the operational drilling pressures remain within the safe limits to prevent soil fracturing. The name of the party responsible for monitoring the work must be specified. 9 . Bridges Crossing Levees. a. The bottom of low steel of the bridge shall be above the design crest elevation of the levee. No notching into the levee will be allowed. b. All bents should be located to minimize the number of bents located within the template of the levee. Driving of piles within the template of the levee will not be allowed . Bents at these locations should only be designed as drilled piers. c. Bridges will not be located where their construction will block maintenance access roads presently located within the flood way. d. All storm water runoff from bridge decks must be piped to grade to prevent erosion within the floodway . e . Re-vegetated mat type slope protection must be provided from the top of the levee to the floodway bottom under the shadow line of the bridge. SWFP 1150-2-1 5 f. The bridge must be designed to minimize the number of pier bents. If the new bridge is within 500 feet of an existing bridge the new pier bents must be in alignment with the adjacent bridge. 10. Buried Lines Parallel to Levees and Channels. a. Buried lines parallel with a levee ( either on the river side or land side) will not be allowed where the buried lines final location will be within the extended template of the levee. For example, a line buried 5 feet deep must be at least 15 feet away from the toe of a levee with a I vertical on 3 horizontal slope. b. Sumps, ditches, swales, or other project features crossed by the buried line shall be restored to their pre construction condition. c. Buried lines parallel with the channel bank must be at least 25 feet from the projected river channel slope template. d. When a buried line crosses a discharge channel, place the line on piers with the piers aligned so as to provide minimal obstruction to flow in the discharge channel and designed so as to catch minimal debris. The preferred alternative would be to place the line under the discharge channel and encase it with concrete. Extend the encasement a minimum of 5 feet beyond the top of the channel side slopes. 11. River and Channel Crossing Criteria. a. Crossings Under Rivers and Channels by Open Excavation: (I) Bury the line a minimum of 7 feet below the original design river bottom elevation . Should the existing channel bottom elevation be lower than original design grade, the new line shall be the discussed depth below the existing bottom elevation. (2) Sufficiently anchor or encase the line to prevent floatation. (3) Backfill the excavation with material similar to that excavated . If soil is excavated, backfill with compacted impervious fill material and if rock is excavated, backfill with concrete . (4) No cofferdam fill type crossings shall be allowed in water greater than six (6) feet in depth, and will then only be allowed if geotechnical and structural designs prove that sheet piling would not be a viable method. b. Crossings Over Rivers and Channels. (I) Provide a minimum freeboard between the low point of the crossing and the design water surface elevation of three feet or to the top of any levee , whichever is higher. (2) The obstruction caused by the supporting bridge and its piers shall not significantly reduce the carrying capacity of the floodway . No longitudinal cross bracing will be used. (3) Submit final plans and hydraulic computations to ind icate that the proposed project would not reduce the floodway capacity. (4) Projects crossing navigable waterways (Trinity River downstream from Riverside Dri ve in Fort Worth , Texas) shall require a U nited States Coast Guard permit. Clearances and requirements shall be as directed by the Coast Guard. SWFP 1150-2-1 6 12. Roadway or Railroad Crossings. a. The low steel of a bridge shall have an elevation not lower than the crown of the le vee or top of bank or 3 feet above the design water surface , whichever is higher. Contact CESWF for the current des ign water surface at the location of the proposed roadway crossing . Additional clearances shall be required for fixed spans over navigable waterways. b . Submit final plans and hydraulic computations to indicate the proposed roadway or bridge would not reduce flows or project capacity. Projects will not be approved that reduce the carrying capacity of the project. c. Any roadway over a navigable waterway will require a permit from the United States Coast Guard. d. See Paragraph 9 for special requirements for crossing levees. e. Hold temporary roadway fill to a minimum to prevent increasing the water surface elevat ion should a flood occur during the construction period. Construct all temporary ramps from levees gomg m a downstream direction . This will prevent flows from being directed into the face of the levees. 13. Headwall, Chutes, Gate Valves, Flap (Automatic) Gates, etc. a. Install headwall , gate valve structures, flap (automatic) gates , and other types of outfall structures in such a manner to prevent obstruction of flow or creation of scouring conditions within the project. All headwalls must transition with the slope and flow discharge points must be at an elevation equal to the bottom of the slope or at the normal water surface . Chutes will not be allowed unless they are the only viable alternative. b. All structures shall be installed in such a manner so as to not create maintenance problems. 14. Pump D ischarge Pipelines Over Levees. a. The invert of the discharge shall be at the toe of the protective works (levee) and shall be free -vented at the highest point. For very large lines deviation from this criteria may be considered, but under no condition shall excavation be permitted into the levee. See Paragraph 5 for requirements for crossing over a levee on grade. b. Flap (automatic) gates are not required atthe outfall of the discharge li nes. 15. Electrical and Telephone Criteria for Overhead Wire Crossings. a. The local sponsor may require directional boring under the levee as opposed to an overhead crossmg. b. No structure (poles or otherwise) shall be located closer than 15 feet from the toe of any levee. c.

SWFP 1150-2-1 7 e. Provide a minimum vertical clearance of 28 feet between the natural ground and the low wire at the low point of the sag in the area of the project channel , or three feet above the project design water surface level, whichever is higher. (Check Electrical Code for minimum clearance of high voltage lines .) f. Locate guy wires and anchors in such a manner that they do not interfere w ith the operation and/or maintenance of the channel, levees , or re lated structures . No anchors may be placed on the levee . 16. Low Dams or Diversion of Flows. a . Submit plans , hydraulic and structural computations, and specifications for low dams or other obstructions fo r review and comments prior to the construction of any type dam structure in a project area . These plans wi ll be reviewed to determine if adverse hydraulic or structural effects would occur within the project as a result of the proposed construction. Prior to an extensive engineering stud y for an y type of water barrier in a project, the CESWF and the local sponsor will review the concept plan , proposed location , and purpose . b. Diversion of flows into or out of a project area shall be reviewed as to possible adverse hydraulic or structural effects . 17 . Process fo r Abandoning Existing Pipelines. a. Requests to abandon exi sting buried pipelines within a project shall be submitted in writing to CESWF an d the local sponsor. No buried line within a floodway may be abandoned without the review and approval of CESWF and the local sponsor. b. As a minimum, the portion of the abandoned pipeline under a levee shall be completely filled with concrete or grout to prevent seepage through the abandoned line during flood conditions. c . Abandoned buried pipelines that are located on floodwa y property, but are not located under a levee shall be plugged at each end with concrete or grout. d. Any structures associated with abandoned buried pipelines, for example, manholes , shall be removed and the resulting hole filled and compacted in accordance with the provisions in paragraph 4j. e . Above -ground abandoned pipelines shall be removed from floodway right-of-way, including any associ ated structures. 18. Construction of Recreation Facilities. Submit plans to th e CESWF fo r revi ew and approva l on any proposed recreation type facilitie s to be con stru cted in an existing or approved Federa l proj ect ar ea. E ach plan shall include hydraulic computat ions and will be rev iewed fo r indi vidual and cumul at iv e effect s to determine if the propo sed con struct io n wou ld produce adve rse effects on an exist ing or approve d project area . If adverse effects on the carrying capacity of t he project are determ ined, th e proj ect will be d isapproved. The lo cal sp on sor may construct mino r rec re ati on im provements as needed so long as fi nal as - bu ilt plans are prov id ed to CESWF. 19. Planting of Trees W ith in a Fl oodw ay . a. The purpose of a Fed eral flood protection project is to carry fl oodwater through an urban area . Anythi ng in the · flood way that re stricts flow or can catch fl oat ing debris wi ll re duce the carrying ca pacity below its de si gn lim its and will not be allowed. The loc al sponsor is directed to remove all trees on the SWFP 11 50 -2 -1 8 levees or adjacent to the channel and also as many other trees and obstructions within the floodway as reasonably possible. b. Planting of trees on the levees will not be allowed nor approved. c . Planting of additional trees within existing flood protection projects or adjacent to channels is not encouraged and will be evaluated only on a case-by -case basis. Only trees with deep -type root systems and high canopies may be planted in selected areas of existing flood protection projects. The plantings shall be a minimum of 50 feet away from the toe of the levee or the top of the channel bank. Trees may be placed no closer than at an average spacing of 100 feet, center-to -center. Prune trees to permit mowing immediately adjacent with tractor type mowers. No bush or vine type p lants will be permitted. Minimum application of ground cover plants for slope protection will be allowed, subject to approval by the local sponsor. d . Submit a coordinated planting plan with hydraulic computations for review and approval. This plan must also show all existing trees within 1000 feet of the proposed new trees.
