PWS for HDD Kaiser Well 08-25-09

Performance Work Statement for Relocate Kaiser Well Line Using Horizontal Directional Drilling (HDD)

BACKGROUND

This project involves using horizontal directional drilling to relocate approximately 500 linear feet (LF) of a 4 inch diameter PVC pipeline used to supply water from the Kaiser Well to the recently completed Brood Fish Facility at the National Center for Cool and Cold Water Aquaculture (NCCCWA) located in Leetown, WV. A direct buried cable supplies power for the well pump and is adjacent to the existing PVC pipe. This cable shall be relocated along with the PVC pipeline. The purpose of this project is to use horizontal directional drilling to relocate a portion of the pipeline that was installed on private property.

SUBMITTALS

The Contractor shall submit four copies of the submittals to the Contracting Officer for review 30 days after contract award. Corrections or comments made during this review will not relieve the Contractor from compliance with requirements of the drawings and specifications. This check is only for review of general conformance with the design concept of the project and general compliance with the information given in the contract documents. The following shall be submitted:

4 inch PVC pipe, shutoff valves, fittings Utility manholes/boxes Power cable As-built drawing

DESCRIPTION OF SERVICES

The contractor shall furnish all labor, supervision, equipment, and material to perform the following services necessary for relocation of the Kaiser Well pipeline:

1. The contractor shall field verify the property lines between Government land and the Sagers property in the vicinity of the existing pipeline. This task shall be completed before any horizontal directional drilling is performed.

2. Perform horizontal directional drilling for the new 4 inch PVC pipe and well pump power cable between the connection points annotated on RMF Engineering, Inc. drawings C2.04 and C2.05, approximately 500 LF. The location and direction of the new tunnel(s) shall lie on Government owned land with minimum practical length. Expect hard rock in the soil in this area.

3. Install new 4 inch diameter PVC pipe and power cable for well pump, approximately 500 LF. New power cable shall match existing. Electric power is 240V, single phase. Existing Kaiser Well pump motor is 10 Hp.

4. Provide and install utility manholes at the connection points located on RMF Engineering, Inc. drawings C2.04 and C2.05. The manholes will be used to tie in the new 4 inch PVC pipe to existing PVC.

5. Provide and install a 4 inch diameter PVC “Y” fitting on the new PVC pipe at the connection point located on RMF Engineering, Inc. drawing C2.05. This “Y” fitting will be utilized for future use to tie in another well.

6. Provide and install a shut-off valve and drain blowoff for each leg of the “Y” fitting. Drain blowoff shall be per RMF Engineering, Inc. drawing C5.02 detail 11. The drain blowoff is used to drain pipe installed above the frost line when not in use.

7. Perform hydrostatic test on newly installed PVC pipe. Pressure test to 60 psi.

8. Provide and install utility boxes at the connection points located on RMF Engineering, Inc. drawings C2.04 and C2.05.

9. Splice the new electrical cable to existing cable sections at the utility boxes.

10. Connect new PVC pipe to existing Kaiser Well pipe sections. Downtime of the Kaiser Well shall be limited to 5 hours to complete pipe and electrical connections.

11. Remove and dispose of existing 4 inch diameter PVC pipe between connection points located on RMF Engineering, Inc. drawings C2.04 and C2.05.

12. Provide as-built drawing showing property lines, utility boxes and location of new PVC pipeline.
