All diameters Steel Water Pipe (AWWA C200). PART 3 EXECMON 3.01 TRENCH EXCAVATION A. Trench excavation shall include material of every description and of whatever substance encountered. Pavement shall be out with a saw, wbeel or pneumatic chisel along straight lines before excavating. B, Strip and stockpile topsoil from grassed areas crossed by trenches. At the Contractor's option, I topsoil may be otherwise disposed of and replaced, when required, with approved topsoil of equal duality. 02221-2 G C. While excavating and backfillutg is in progress, traffic shall ba maintained, and all utilities and other property protected as provided in the General Conditions and General Requirements. D. Trenches small be excavated to the depth indicated on the Drawings and in widths sufficient for laying the pipe, bracing and for pumping and drainage facilities. The bottoin of the excavations shall be, fain and dry and in all respects acceptable to the Engineer. Trench width shall be Practical. minimum. E. Excavation and dewatering shall be accomplished by methods, which preserve the undisturbed state of subgrade soils. The trench may be, excavated by machinery to, ar just behove the designated subgrade, provided that material remaining in the bottom of the trench is no more than Subgrade soils which become soft, loose, "quick", or otherwise unsatisfactory slightly disturbed as a result of inadequate excavation, dewatering or other construction methods shall be removed and replaced by screened gravel fill as required by the Engineer at the Cont"ractor*s expense. F. Clay and organic silt soils are particularly susceptible to disturbance due to construction operations. When exdavation is to'end in such soils, use a smooth -edge bucket to excavate the last 1-ft of depth. G. Where pipe is to be laid in screened gravel bedding, the trench may be excavated by machinery to the normal depth of the pipe provided that the material remaining in the bottom of the trench is no more than slightly disturbed. a Where pipe is to be. laid directly on the trench bottom, final excavation at the bottom of the trench a fiat bottom true to grade upon undisturbed material. shall be performed manually, Providing Bell holes shall be trade as required• 3.02 DISPOSAL OF MATERIALS A. Excavated maierW shall be stacked without excessive surcharge on the trench bank or obstruatiug free access to hydrants and gate valves. Inconvenience to traffic and abutters shall be avoided as mach as possible. Excavated material shall be segregated for use in backFtlling as specified below. $. It is expressly understood that no excavated material shall be removed from the site of the work or disposed o% except as directed by the Engineer. When removal of surplus materials has been approved by the Engineer, dispose of such surplus material in approved designated areas. C. Should conditions maize it impracticable or unsafe to stack material adjacent to the trench, the material shall be hauled and stored at a location designated by the Owner. When required, it shall be re -handled and used in backhlling the trench. 3.03 SHEETING AND BRACING place and maintain sheeting and bracing required by Federal, State or local safety A. Furnish, put in requirements to support the sides of the excavation and prevent loss of ground which could endanger personnel, damage or delay the work or endanger adjacent structures. If the Bagirieer is ' of the opinion that at any point sufficient or proper supports have not been provided, he/she may order additional supports placed at the expense of the Contractor. Compliance with such order shah not relieve the Contractor from his/her responsibility for the sufficiency of such supports. 02221-3 Care shall be take11 to prevent voids outside of the sbeeting, but if voids are formed, they shall be immediately filled and rammed- $. Where sheeting and bracing is required to support the sides of trenches, engage a professional engineer, registered in the State of Texas, to design the sheeting and bracing. The sheeting and bracing ineWIDd shall be in conformity with the design and certification of this shall be provided by the professional engineer. C. When moveable trench bracing such as trench boxes, moveable sheeting, shoring or plates are used to support the sides of the trench, care shall be taken in placing and moving the boxes or supporting bracing to prevent movement of the pipe, or disturbance of the pipe bedding and the screened gravel ba-ckfitll. L. When installing rigid pipe, any portion of the box extending below mid diameter shall be raised above this point prior to moving the box ahead to instaIl the next pipe. This is to prevent the separation of installed pipe joints due to movement of the box 2. When installing semi -rigid pipe trench boxes, moveable sheeting, shoring or plates shall not be. allowed to extend below mid -diameter of the pipe. As trench boxes, moveable sheeting, shoring or plates are moved, screened gravel shall be placed to fill any voids created and the screened gravel and ba-cldill shall be recompacted to provide uniform side support for the pipe. D. perrnissiD-n will be given to use steel sheeting in lieu of Food sheeting for the entire job wherever the use of sh,:ethng is necessary. The cast for use of sheeting will be included in the bid items for pipe and shall, include full compensation for driving, bracing and later removal of sheeting. E- All sheeting and bracing shall be carefully removed in such manner as not to endanger the - consfructian of other structures, utilities, or property, whoiher public or private. All voids left after withdrawal of sheeting shall be immediately refilled with sand by ramming with tools especially adapted to that propose, by watering or otherwise as directed. F. No payment will be given for sheeting, bracing, etc., during the progress of the work. No payment will be, given for sheeting, which has actually been left in the trench for the convenieace of the Contractor. G. Sheeting driven below mid, -diameter of any pipe shall remain in place from the driven elevation. to at least l-ft above the top of the pipe. 3.04 TEST PITS A. Excavation of test pits maybe be required for the purpose of locating underground utilities. or structures as an aid in establishing the precise location of new work. B. Test pits shall be backfilled as soon as the desired information has beeri obtained_ The. backElled surface shall be maintained in a satisfactory condition for travel until resurfaced as specified. 02221-4 i t 3.05 EXCAVATION BELDW GRADE AND REFILL A_ Whatever the nature of unstable material encountered or the groundwater conditions, trench drainage shall be complete and effective. B _ if the Contractor excavates below grade through error or for the Contractor's Dorn convenience, or through failure to properly dewater the trench, or disturbs the sabgrade before dewatering is sufficiently complete, he/she may be directed by the Engineer to excavate below grade as set forth in the following paragraph, in which case the work of excavating below grade and furnishing and placing the refill shall be performed at his/her own expense. G If the material at the level of trench bottom consists -of fine sand, sand and silt or soft earth which may work into the screened gravel notwithstanding effective drainage, the subgrade material shall be removed to the extent directed and the excavation refilled with a 6-in layer of coarse sand, or a mixture graded from coarse sand to the fine peastone, as approved by the Engineer, to form a filter layer preserving the voids in the gravel bed of the pipe. The composition and gradation of gravel shall be approved by the Engineer prior to placement Gravel bacldlI shall thfm be placed in 6-in layers thoroughly compacted up to the normal grade of the pipe. D. GeotexdIe filter fabric may be substituted for filter layer if approved by the Engineer. Filter fabric shall be, Mimfi 140N; Supac equivalent, or equal. 3.06 BACIU L IKO ' A. As soon as practicable after the pipe has been laid and jointed, bacldillig shaIl begin and thereafter be prosecuted expeditiously. Bedding gravel, as specified for the type of pipe installed, shall be placed up to 1-ft over the pipe. B. Where the pipes are laid in the yard, the remainder of the trench shall be Mod with common fill material in layers not to exceed 3-ft and mounded 6-in above the existing grade or as directed Where a loam or gravel surface exists prior to excavations in the yard, it shall be removed, conserved and replaced to the full original depth as part of the work under the pipe items. In some areas it may be, necessary to remove excess material during the clean-up process, so that the ground may be restored to its original Ievel and condition. C. Where the pipes am laid in paved areas, the remainder of th6 trench tip to a depth of 1-ft below the bottom of the specified permanent paving shall be backfiiled with common fill material in layers not to exceed 1-ft and thoroughly compacted. The subbase layer for paving shall be of bank -run gravel thoroughly compacted in 6. in Layers. D. To prevent longitudinal movement of the pipe, dumping backf ll material into the trench and then i spreading will not be permitted until selected material or screened gravel has been placed and { compacted to a level 1-ft over the pipe. E. Backfill shall be, brought up evenly on all sides. Each layer of backfill material shall be thoroughly compacted by rolling, tamping, or vibrating with mechanical compacting equipment } or hand tamping, to 95 percent compaction. If rolling is employed, it shall be by use of a suitable } ` roller or tractor, being careful to compact the fill throughout the full width of the trench_ I- 02221-5 F. Compaction shall be by use of Band or pneumatic ramming with tools weighing at least 20 lbs. The, material being spread and compacted in layers not over 8-in loose thiclt. If necessary, sprinkling shall be employed in conjunction with rolling or rang. G. Subject to the approval of the Engineer, fragments of ledge and boulders smauar than 6-in may be used in trench backfill providing that the quantity in the opinion of the Engineer, is not excessive.

TEXAS _ FOR DUCTILE IRON PIPE PART 3 EXECUTION 3.01 PREPARATION A. Remove lumps of clay, mud, and cinders from pipe surface prior to installation of polyethylene encasement. Prevent soil or embedment material from becoming trapped between pipe and polyethylene. B. Fit polyethylene film to contour of pipe to effect a snug, but not tight fit; encase with minimum space between polyethylene and pipe. Allow sufficient slack in contouring to prevent stretching polyethylene where it bridges irregular surfaces, such as bell -spigot interfaces, bolted joints, or fittings, and to prevent damage to polyethylene due to backfilling operations. Secure overlaps and ends with approved adhesive tape or approved plastic tie straps to hold polyethylene encasement in place until backfilling operations are complete. C. For installations below water table or in areas subject to tidal actions, seal both ends of polyethylene tube with adhesive tape at joint overlap. Circumferentially wrap with tape or plastic tie straps every two feet along the barrel. 3.02 INSTALLATION A. 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. Lower pipe into trench and make up pipe joint with preceding section of pipe. Make shallow bell hole at joints to facilitate installation of polyethylene tube. 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. 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. 4. 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.

The proposed 36" diameter water main right-of-way has an approximate length of 14,403 feet. In addition, a corrosivity evaluation was conducted along the proposed right-of-way of the 16" diameter waterline to be installed along Tarrant Main, from the Trinity Rail Express right-of-way to South Pipeline Road. The approximate length of the proposed 16" diameter waterline is 3,010 feet. The proposed 36" and 16" diameter pipelines will be offered for bid with the following material alternatives: l s Bar -wrapped concrete cylinder pipe (AWWA — C303). Dielectrically coated carbon steel pipe. o Ductile iron pipe. Upon completion of the corrosion 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 corrosion evaluation and corrosion protection design. 2..0 EXECUTIVE SUMMARY 2.1. A soil resistivity survey conducted along the proposed water main alignment indicates the soil may be corrosive to the three metallic pipe material options being considered - concrete cylinder pipe, dielectrically coated steel and ductile iron — from Euless South to the Trinity Boulevard. Corrosion protection measures are recommended for all of these materials along the indicated pipe section to preserve the physical integrity of the pipe. 2.2. The mortar coating on the concrete cylinder pipe (CCP) option provides corrosion protection for the embedded steel components. However, areas of low soil resistivity 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 from pipe station 192+00 to station 286+00. The remaining sections of the 36"/16" diameter pipe do not require additional corrosion control measures. 2.3. The installation of a galvanic anode cathodic protection system along the full length of the water main is recommended for the dielectrically coated steel pipe option to minimize the probability of corrosion at coating holidays. 2.4. The annealing oxide and asphaltic shop coating typically present on the ductile iron pipe should be supplemented with the installation of polyethylene encasement along the full length of the pipe to protect its external integrity from the corrosive effects of the soil. In addition, cathodic protection shall be provided from pipe station 192+00 to station 286+00. 2.5. Joint bonding of the concrete cylinder pipe and the ductile iron pipe options is required to maintain the electrical continuity along the entire pipe. Electrical continuity is a necessary condition to apply cathodic protection. For the dielectrically coated steel pipe option, joint bonding at mechanical connections is also required. 2.6. Regardless of the pipe material, the water main must be electrically isolated at its connection to the existing 36" water main Contract 1 and at laterals. For the CCP and DIP options, the water main must also be electrically isolated at the gate valve located at station 195+40. 2.7. Test stations should be installed at foreign line crossings, cased crossings, major road crossings, and at the location of all in -line isolators to monitor the effectiveness of the proposed cathodic protection system and to allow for DC interference testing. 3.0 CORROSIVITY EVALUATION A laboratory soil electrochemical analysis was not conducted since soil samples were not available for a corrosivity investigation. Therefore, the soil corrosivity analysis and corrosion control recommendations presented in this report are based on the results of the field soil resistivity survey only. During the field evaluation, Corrpro also investigated the possible influences of stray DC currents and overhead high -voltage AC power lines on the proposed waterline. OA The evaluation performed is the basis for determining the corrosion protection requirements for the bar -wrapped concrete cylinder pipe (CCP), dielectrically coated carbon steel pipe, and ductile iron pipe (DIP) options. 3.1 RESULTS AND ANALYSIS Field testing was performed to collect electrical data pertaining to the corrosivity of the proposed pipeline alignment with respect to CCP, carbon steel and DIP. Soil resistivity measurements were recorded from grade to depths of five, ten and fifteen feet at fifteen (17) locations along the proposed alignment_ This data is recorded in Appendix A. 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 pipe is to be installed, is summarized as follows: Trinity Railway Express Water Main Extension Project Soil Resistive Statistics From F.M. 157 to S.H. 360 5'-10, 10'-15' Minimum 2,011 1,022 Maximum 58,393 40,705 Average 16,231 12,693 <1,000 0.0% 0.0% % < 2,000 0.0% 14.3% % < 3,000 28.6% 28.6% % > 3,000 71.4% 71.4% % > 5,000 50.0% 50.0% Trine Railway Express Water Main Extension Project Soil Resistivity Statistics Along Tarrant Main 5'-10' 10'-15' Minimum 3,074 4,148 Maximum 9,163 13,340 Average 5,768 7,830 %<1,000 0.0% 0.0% % < 2,000 0.0% 0.0% % < 3,000 0.0% 0.0% % > 3,000 100.0% 100.0% % > 5,000 66.7% 66.7% 3 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. Metallic foreign pipeline crossings that may cause interference due to stray currents were identified at the following pipe stations_ 167+50 (gas), 194+60 (gas), and 285+75. DC interference conditions, which may lead to accelerated corrosion of the waterline, are possible at cathodically protected foreign line crossings. High voltage power transmission lines were observed parallel to the proposed waterline from pipe station 252+00 to station 265+00. Therefore, AC interference may be of a concern during the installation and operation of the proposed 36" waterline. 3.2 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 corrosion control requirements that could be considered for the proposed 36" Diameter Trinity Railway Express Water Main Expansion. Areas of low soil resistivity along the proposed pipeline alignment and the presence of potential sources of DC interference (i.e., cathodically protected foreign pipelines crossing the waterline alignment) indicate that ferrous materials will probably be subject to electrochemical corrosion between pipe stations 192+00 and 286+00. The high pH of the mortar coating on the CCP provides corrosion protection for the embedded steel components. Nevertheless, low soil resistivity, particularly if caused by high moisture content and high concentrations of salts, may compromise the level of corrosion protection in the long run, making the steel susceptible to corrosion. Therefore, cathodic protection is recommended from pipe station 192+00 to station 286+00. The remaining sections of the CCP option do not require the implementation of corrosion control measures. The dielectric coating on the steel pipe will be the primary corrosion control mechanism. Corrosion will occur, however, at those areas where there are breaks in the coating. Therefore, the coating must be supplemented with cathodic protection throughout the full length of the pipe. rd 4.0 Polyethylene encasement for the full length of the pipe and cathodic protection from pipe stations 192+00 to station 286+00 are the recommended corrosion control methods for external corrosion protection of the ductile iron pipe option. No additional corrosion control measures are required for the remaining sections of the ductile iron pipe option. Electrical continuity is necessary to apply cathodic protection. The CCP option and the ductile iron pipe option are electrically discontinuous because of the dielectric sealing materials used at each pipe joint. Joint bonding will therefore be required to maintain electrical continuity for the CCP and for the ductile iron pipe options. The same requirement applies to the dielectrically coated steel pipe at non -welded joints. It is necessary to electrically isolate the proposed 36" diameter water pipeline at all tie-ins to other buried metallic pipelines regardless of the pipe material. In addition, for the CCP and DIP options, the pipe must be electrically isolated at the gate valve at Euless South Main Roadway (Station 195+40) to separate the cathodically protected pipe section from the non-cathodically protected pipe section. The water pipe must also be electrically isolated from steel casings where the pipe passes through casings. Monitoring test stations should be installed for the pipeline at foreign line crossings, cased crossings, major road crossings and at the location of all in -line isolators. CORROSION PROTECTION DESIGN REPORT 41 SUMMARY The proposed water pipeline will be offered for competitive bidding based on the following alternative configurations: e 36" diameter bar -wrapped concrete corrosion control joint continuity connections to configuration. system consisting c bonds, monitoring existing pipelines cylinder pipe (AWWA C303): A f galvanic anode cathodic protection, test stations and joint isolation at is recommended for this pipeline ® 36" diameter 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. 5 e 36" diameter ductile iron pipe: A corrosion control system consisting of polyethylene encasement, galvanic anode cathodic protection, joint continuity bonds, 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 AWWA 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, in accordance with the ANSI/AWWA C222 Standard, is recommended for the external surfaces of the steel pipe option. 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. Installation of a polyethylene encasement is recommended. The polyethylene encasement for the external surfaces of the ductile iron pipe material should be in accordance with the AWWA C-I05/A21.5 Standard. The high -density, cross - laminated polyethylene film is recommended for this application. Appendix E presents the recommended specification for polyethylene encasement for ductile iron pipes. 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 consists of seventeen (17) anode groundbeds, each consisting of ten, 20-pound prepackaged high potential magnesium anodes installed vertically at 10-foot spacing. The anode groundbeds are to be installed between pipe stations 195+40 and 286+04. This translates to an average spacing of approximately 533 feet between anode groundbeds- in, The recommended galvanic anode cathodic protection system for the dielectrically coated steel pipe option consists of nine (9) anode groundbeds to be installed between pipe stations 142+10 and 195+40, and eight (8) anode groundbeds to be installed between pipe stations 195+40 and 286+04. One anode groundbed is recommended for protection of the 16" diameter waterline along Tarrant Main. Each anode groundbed shall consist of ten, 20-pound prepackaged high potential magnesium anodes installed vertically at 10-foot spacing. This translates to an average groundbed spacing of approximately 533 feet from pipe station 142+10 to pipe station 195+40, and an average groundbed spacing of 1,135 feet from pipe station 195+40 to pipe station 286+04. The recommended anode groundbed for the 16" diameter waterline along Tarrant Main shall be installed close to the Iongitudinal center of the alignment (i.e., station 15+50). The recommended galvanic anode cathodic protection system for the ductile iron pipe option consists of eight (8) anode groundbeds, each consisting of ten, 20- pound prepackaged high potential magnesium anodes to be installed vertically between pipe stations 195+40 and 286+04. This translates to an average spacing of 1,135 feet between anode groundbeds. The CCP option will require, in addition, three bonding clips welded across each joint to ensure electrical continuity of the pipeline, while the ductile iron pipe option will require two bonding wires welded across each joint to ensure electrical continuity of the pipeline. For the dielectrically, coated pipe, joint bonding shall be performed at all mechanical connections. No joint bonding is necessary at welded connections. Refer to Appendix D, Specification for galvanic anode cathodic protection systems. 4.5 JOINT BONDING AND ELECTRICAL ISOLATION The 36" diameter Trinity Railway Express Water Main Extension shall be electrically isolated from existing metallic transmission mains and laterals. For the CCP and DIP options, the waterline shall also be electrically isolated at the gate valve at Euless South Main Roadway (Station 195+40) to separate the cathodically protected pipe section from the non -catholically protected pipe section. Bonding of non -welded joints is required for the CCP, the ductile iron pipe and the dielectrically coated carbon steel pipe material options. Bond cables should be thermite welded across non -welded steel pipe joints and across all ductile iron pipe joints. Steel clips should be welded across CCP joints except when the joints are restrained by welding. Refer to Appendix B, Joint Bonding and Electrical Isolation. VA 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 crossing, all tie-ins from laterals and spur lines, and isolation joints. Cathodic protection monitoring test stations should also be installed so as to limit the maximum distance between two test stations to one mile. 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. CP - Test station installed at the ends of metallic pipeline casings with lead wires to the pipeline and lead wires to the casing (see CP type test station 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 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_ 4. IF -Test station installed across insulating joints. (see IF type test station on the cathodic protection drawings). Note: Lead wires and bond wires are to be installed on the foreign pipelines by the foreign pipeline owners. The City of Fort Worth will make arrangements with the foreign pipeline owners for installation of lead wires and bond wires on the foreign pipelines. Contractor SHALL NOT install lead wires or bond wires on foreign pipelines. k- 4 Trinity Railway Express Water Main Extension Project Fort Worth, Texas CCP Option Test Station Schedule Station No. Description Type 142+11 Connection to Existing 36" Waterline IF 163+50 Cased Crossing at RR spur CP 165+50 Cased Crossing at RR spur CP 167+55 Gas line crossing (if metallic) FL 170+00 Cased Crossing at RR spur CP 170+90 Cased Crossing at RR spur CP 191+50 Cased Crossing at Euless South Main Roadway CP e 195+00 Cased Crossing at.Euless South Main Roadway CP 198+10 i Anode Groundbed TS 203+45 Anode Groundbed TS 208+80 Anode Groundbed TS 213+75 Anode Groundbed TS 219+10 Anode Groundbed TS 224+45 Anode Groundbed TS 229+80 I Anode Groundbed TS 235-+-15 Anode Groundbed TS j 240+50 Anode Groundbed TS 245+00 i Anode Groundbed TS 6 S Trinity Railway Express Water Main Extension Project Fort Worth, Texas CCP Option Test Station Schedule Station No. Description Tyne 248+95 Cased Crossing CP 250+10 Cased Crossing CP 252+50 Anode Groundbed TS 257+85 Anode Groundbed TS 263+20 Anode Groundbed TS 268+55 Anode Groundbed TS 275+60 Anode Groundbed TS 279+25 Anode Groundbed TS 278+00 Cased Crossing at S.H. 360 CP 281+70 Cased Crossing at S.H. 360 CP 284+60 Anode Groundbed TS 284+05 Cased Crossing at Trinity Blvd. CP 285+95 Cased Crossing at Trinity Blvd. CP 286+13 Connection to existing 24" pipeline 1F On 16" Diameter Waterline along Tarrant Main Station No. Description Tyne 21+75 Koch HP Gas Line Crossing FL 10 s.

The installation of galvanic anodes at corrosive areas of the waterline alignment will provide the means for external corrosion control of the waterline. 4.7.2 The proposed 36" diameter Trinity Boulevard Water Main should be electrically isolated from the existing metallic transmission mains and laterals. For the CCP and DIP options, the waterline shall also be electrically isolated at the gate valve at Euless South Main Roadway (Station 195+40) to separate the cathodically protected pipe section from the non-cathodically protected pipe section. 4.7.3 Joint bonding of the concrete cylinder pipe and the ductile iron pipe options is required to maintain the electrical continuity throughout the pipe section that needs to be cathodically protected. For the dielectrically coated steel pipe option, joint bonding at mechanical connections is also required at the pipe sections that require cathodic protection. 4.7.4 Proper monitoring of the cathodic protection system will be achieved through test stations installed- at foreign pipeline crossings, cased crossings and buried isolation fittings. In addition, permanent reference cells will allow monitoring at groundbed locations and at buried isolation fittings.
