Construction Engineer / CONT' By •/"/ e", Title Title / ��/ Rev. 8-19-85 SPECIFICATIONS FOR CHANGE ORDER NO. 1 RELOCATION OF CITY OF CORPUS CHRISTI PIPE LINES (PROJECT "A") FOR IMPROVEMENTS TO INTERSTATE HIGHWAY 37 AT SHARPSBURG ROAD RELOCATION OF 12" MUD LINE GENERAL: These specifications govern the work required in connection with the relocation of a 12" aebestoa-cement "mud line" along the south side of Up River Road, also known ae the South Frontage Road of Interstate 37, easterly from the Missouri Pacific Railroad. "Relocation" here means the conetrudtion of a new line and the abandonment of the old line. The new line will conaiet of approximately 60 linear feet of 12" ductile iron pipe and 795 linear feet of 12" asbestos -cement pipe, with ductile iron fittings. WORK ITEMS, The work to be done includee the following items: 1. Shift the propoeed location of the 36" drain line 1.5 feet to the south, so that it is 11.5 feet south of the right of way line all the way. (This eliminates the. deflection originally planned et the easterly end.) 2. Special measures will be required in constructing the 36" line where it paeeea a power pole structure at approximately Sta. 3 + 10. A length of 6 feet at the surface (3 feet each side) at the power pole shall be undisturbed, and a minimum of 12 feet of 48" steel pipe casing or tunnel liner shall be installed by boring, jacking, or tunneling, set at the proper line and grade for the 36" line. The casing or liner shall conform to the existing plane and specifications as to materials and installation. 3. The excavation for and backfilling of the 36" drain line shall be performed in a manner that will prevent settlement of the proposed new 12" mud line, and will permit trenching for it without caving. See Item 4. The new 12" line is to be placed 5 feet south of the right of way line, so that the 12" and the 36" linea will be 6.5 feet center to center horizontal distance. The 12" line will be shallower than the 36" line, as shown an the profile. (No change of the grade of the 36° line is proposed herein.) The 12" line shall not be placed until the backfill for the 36" line has aged for a minimum of 3 weeks. The scheduling of the 36" line shell be moved forward to allow for this. 4. The 36" drain line, when installed, shall be wrapped in polyethy- lene and encased in sand as described in Par. F-3 of the specifica- tions, then backfill shall be placed to the surface, using a vibratory compactor and placing the material in lifts not exceeding 8" loose • Rev. 8-19-B5 thickness. The material ahall be wetted sufficiently to secure near - optimum compaction. Upon completion, the backfill shall be further compacted by rolling the eurface with a pneumatic roller with at least 10 passes. At any stege and on completion, the fill shall be quite resistant to penetration by a probe rod, to the satisfaction of the Engineer. 5. On the existing 12" mud line on the east side of the railroad, in lieu of removing and reinstalling a section of the 12" line (Contract Item 12) for the installation of the 20" casing for the relocated rail- road embankment, es shown on Sheet 10 of the plana, the Contractor will be allowed to leave the 12" line in place and use a longitudinally- eplit casing, Fully welded after installation. The edges ahall be shop -cut and shop beveled for welding. The length of casing shall be increased by 10 feet, making a total of 48 feat. The existing 12" line shell be excavated and cleaned off, and shall be firmly supported and kept in service while the work is going on. Wooden skids shell be pro- vided on each pipe joint, strapped to the pipe. The end of the new casing shall be plugged ae specified. The earth under the 12" line shall be removed to a sufficient depth to allow accurate shaping for the underside of the steel casing for about 90°. Where shaping is in- accurate, the Engineer may require lean concrete bedding at the Con- tractor's cost. Backfill shall be tamped tightly around the casing. 6. The east end of the existing 12" line, where it turns to go north- ward across the highway, shall be exposed et an early time for confir- mation of the depth, alignment, and fittinga required for the reloca- tion. 7. The main run of new 12" line shall be asbestos -cement pipe. At the east end, beginning with the 22-1/2° bend just before the 12" line will cross over the 36" line, and extending to the connection point, the line shall be ductile iron. 8. Where the 12" line pasties near the anchorage of the north power pole, at approx. Sta. 3 + 45, the Contractor shall investigate the de- gree of conflict if any. The Engineer may authorize a slight deviation of alignment of the 12" line at this location. The Contractor shall install not lees than 8 linear feet of 20" steel casing at the anchor- age, to prevent disturbing the integrity of the anchorage. If a great- er length is necessary, it shell be installed at the Contractor's cost. The casing shall conform to the original contract specifications, ex- cept it ahall.be installed by jacking or boring. In lieu of sealing the ends, the casing shell be "flooded" with sand. Skids shall be used if necessary for the installation of the 12" pipe. 9. After the new 12" line hes been constructed to points near each proposed end tie-in, the Contractor shell arrange with the City Water Division to take the mud line out of service for the purpose of making the tie-ins. This period shall not exceed 48 hours. The Contractor shall arrange to handle any leakage or accidental drainage coming down the line. The Contractor shall have on hand an adequate selection of • Rev. 8-19-85 alternate materials end fittings for contingencies in making the connections. The existing pipe shall be cut, fittings removed where necessary, and the new line connected es quickly es possible. Benda shall be blocked without delay. The ends of the abandoned line ehall be plugged with concrete. 10. Aabeatoe cement pipe shell be Claes 150, conforming to AWWA C 400. The pipe, couplings, and gaskets shell be approved by The Underwriters Laboratoriee, Inc. Joints shall be of the push -on type, with synthetic rubber gaskets, conforming to ASTM D 1869. Fittings shall be ductile iron, either push -on or mechanical joint. 11. Ductile iron pipe shall be in accordance with AWWA C 151 end the specifications, and shall have restrained joints, U.S. Pipe "TR Flex" or equal. Pipe shall be Class 51 (0.34" wall). Fittings shall have restrained joints compatible with the pipe. 12. Benda shall be blocked with concrete, as specified in Par. F-8, whether or not a "restrained" fitting. Two special blocking details are shown on the plan. 13. The 12" line shall be pressure -tested for leakage prior to making the end connections. 14. The concrete 'lining of the drainage ditch shall be restored where cut. This work is subsidiary to all other items. 15. Where these supplemental specifications are silent as to materials or method° of installation, the original plana and specifications shall govern. MEASUREMENT AND PAYMENT: 1. The realignment of the 36" drain line results in an increase of ap- proximately 3 linear feet, under Bid Item 9, 36" Drain Line Claes 51. 2. Bid Item 12 of the Contract (Relay 12" Drain Line) is eliminated and will be zero in the final measurement. 3. Bid Item 16 of the Contract will be increased to 48 linear feet, an increase of 10 feet. This covers the extension near the railroad. 4.

If longer casing is installed, no additional payment is author- ized. 5. A Bid Item 19 will be created, covering "12" A -C Mud Line," mese- ured ea installed, by the horizontal linear foot, and paid et the rate agreed to in the change order. • Rev. B-19-85 6.
