Statement of Work

2023 PPW Piping Repair Project

USDA, Ames

3-1-2023

Project Requirements:

This project will include repair work to 3 separate sections of pumped pretreatment waste (PPW) piping buried in the ground in 3 separate areas on the USDA campus in Ames, Iowa.

The first section is the PPW piping that runs from Building 155 to PPW101A. This piping has been determined to have a leak somewhere in its secondary containment allowing ground water to infiltrate the interstitial space of the dual wall piping.

The second section is inside the vault on the east side of Building 156. This secondary piping in this vault has a leak around the secondary containment of an existing wye fitting. Details on the drawings.

The third section is the PPW piping that runs between PPW vault 104 and PPW 103.

The newly installed redundant, dual wall PPW piping has a leak in the secondary containment allowing ground water to infiltrate the interstitial space of the dual wall piping.

SECTION 1: PPW piping between old wastewater treatment plant (Bldg. 155) and PPW vault 101A.

Contractor shall excavate by HydroVac-ing and completely uncovering the existing PPW lines noted in this section (and noted on attached drawings) from building 155 to PPW vault 101A. Once the PPW lines are exposed completely, the USDA will pressure test the section of PPW piping to locate the leak in the outer, secondary containment piping.

Once the leak location has been determined, the Contractor will be responsible for making one patch on the exterior pipe, approximately one foot of piping length entirely around the pipe within the bounds of this section. After the repairs to the dual wall PPW piping is complete, the contractor and USDA personnel will work together to pressure test the piping to verify the integrity of the repairs to the outer wall of the dual wall piping.

Once the piping passes the pressure tests, the Contractor will then be responsible for backfilling the trench and repairing/restoring any disturbed portions of the surrounding area back to its original condition.

Contractor shall be responsible for removing and replacing any of the concrete/asphalt driveway that is removed to expose these PPW pipes back to its original or better condition.

SECTION 2: Buildings 3 and 4 PPW piping repair

Contractor shall be responsible for repairing leak inside vault on the east side of Building

156. The leak is located on the wye fitting and is around one of the joints. Contractor shall be responsible for any excavating that may need done for accessibility to the fitting inside the vault. See drawings for more details. After the repairs to the dual wall PPW piping is complete, the contractor and USDA personnel will work together to pressure test the piping to verify the integrity of the repairs to the outer wall of the dual wall piping.

Once the piping passes the pressure tests, the Contractor will then be responsible for backfilling the trench and repairing/restoring any disturbed portions of the surrounding area back to its original condition. This includes placing sand back inside the vault.

SECTION 3: PPW vault 104 to PPW 103 piping repair

Contractor shall excavate by HydroVac-ing and completely uncovering the existing PPW lines noted in this section (and noted on attached drawings) from PPW 103 to PPW 104 located on the west side of Building 9. Once the PPW lines are exposed completely, the USDA will pressure test the exterior wall of the dual wall piping and locate leak in outer piping. Contractor will be responsible for making one repair to the exterior pipe, approximately one foot of piping length within the bounds of this section. After the repairs to the dual wall PPW piping is complete, the contractor and USDA personnel will work together to pressure test the piping to verify the integrity of the repairs to the outer wall of the dual wall piping. Once the piping passes the pressure tests, the Contractor will then be responsible for backfilling the trench and repairing/restoring any disturbed portions of the surrounding area back to its original condition.

Contractor shall be responsible for removing and replacing any of the fencing that needs to be removed to expose these PPW pipes back to original condition.

Contractor shall be responsible for removing and replacing any of the concrete driveway that is removed to expose these PPW pipes back to its original condition.

Additional Notes for work noted above:

In all areas noted above, the contractor MUST TAKE extreme caution while excavating to not disturb any of the other existing PPW piping and/or any other existing utilities in the area of work. As noted below, the contractor will be responsible for performing or subcontracting the work for utility locates in the area of work prior to any work happening, however, the USDA Personnel will assist in any way possible to help identify potential hazards and their locations. These systems are critical in nature to NCAH operations and must not be disturbed in their operation unless it is a scheduled activity.

For all piping materials (in the ground and in the vaults), the contractor shall match the existing construction, finish, and installation requirements as the existing piping.

Specifications and drawings for the existing installations have been included.

All fencing material needing to be removed to perform piping work must be replaced by contractor with like material and construction once the piping work and groundwork is complete.

Any grounds disturbed (grass, gravel, paving, etc..) in order to expose piping to be worked on, must be returned to original or better conditions after piping work has been completed. Contractor will be responsible for replacing any pavement work that has been removed, reseeding any grassy areas, etc.

Any ground that is disturbed and returned to better or normal conditions due to excavating, equipment access, refilling, etc. must be free of debris, large rocks, construction materials etc.
