Solicitation 12639524Q0191, Attachment 1 Statement of Work Aquaculture Redundancy Project USDA, NCAH, Ames, IA 5/23/24

Background:

The National Centers for Animal Health at 1920 Dayton Ave, Ames, Iowa, accommodates an aquaculture facility located in the basement of building 20. The water service for the aquaculture facility is connected at the most hydraulically remote point of the water service for building 20. In the event of a failure of the building or campus water supply, there is not sufficient pressure and flow to keep aquaculture operating within specified parameters.

Scope:

The objectives of this project are to add redundancy to the aquaculture water supply by connecting the aquaculture system service earlier in the building’s domestic water entrance. The awarded contractor shall add a new, 8” pressure reducing valve along with a dedicated 4” water service to directly supply the aquaculture system from the main water service. Additional valves and a low flow bypass around the new pressure reducing valve (PRV) shall be added throughout the system, as indicated in the drawings. Hot tapping will be required for new piping connections to existing systems. To complete this, the contractor shall:

(REFER TO DRAWING SET FOR LOCATIONS OF NEW AND EXISTING EQUIPMENT)

(See attached specification sheet for valving, insulation, etc.)

1) Hot tap into the existing 8” water service supplying building 20.

a. Install an 8” hot tap saddle (HT-1) and 8” gate valve onto the existing 8” water service downstream of the existing 8” gate valve on the existing water service for building 20.

b. Install an 8” hot tap saddle (HT-2) and 8” gate valve on the downstream side of the existing PRV for connection of new 8” water line.

2) Install a new 8” pressure reducing valve in parallel with the existing 8” PRV.

a. Copper shall be used for all new 8” piping for the new PRV.

b. From the newly installed 8” saddle (HT-1) upstream on the existing water service, install a new 8” copper line and connect it to the downstream hot tapped saddle (HT-2).

c. Install a new Watts® ACV, 150#, pressure reducing valve (or approved equivalent) in the new 8” copper line. This new PRV shall be installed in the open space next to the existing PRV and mounted and supported in such a way as to allow servicing and maintenance of both PRVs and other nearby equipment.

d. Install painted steel structure of sufficient strength to support the new PRV when in operation. Structure shall be approved prior to purchasing/manufacturing and installation.

e. New PRV shall have the same set up and configuration as the existing PRV.

f. Install 2 new 8” gate valves (NV-3, NV-4)on each side of the new PRV to allow for isolation and a third 8” gate valve (NV-5) as indicated in the drawing to facilitate isolation of the 4” water line.

g. New 8” copper water line shall be insulated using the same type of material used on the existing 8” water line.

3) Install a 2” low flow bypass around the new PRV.

a. The 2” low flow bypass shall be copper, and configuration shall match existing PRV low flow bypass.

b. Install (2) new copper 2” ball valves for isolation.

c. Install a new 25-75psi pressure regulator in between the (2) 2” isolation valves.

d. Install (2) new mechanical pressure gauges on each side of the pressure regulator.

e. New 2” low flow bypass shall be insulated using the same make and type of material used on the existing low flow bypass on the existing PRV set up.

4) Install a new 4” Schedule 80 CPVC water service line for aquaculture.

a. The 4” water service to aquaculture shall be 4” Schedule 80 CPVC.

b. From the new 8” water service, downstream of the new PRV (as indicated in the drawings), install a 4” CPVC water service to the existing 2” copper aquaculture water service.

c. Install a new 4” ball valve (BV-1) on the 4” CPVC water line close to the 8” to 4” tee fitting.

d. The service line layout shall be reviewed and approved by the COR. New 4” aquaculture water line shall slope towards aquaculture.

e. Pressure test this new 4” CPVC water service to ensure there are no leaks before placing in service.

5) Install two new 8” valves to allow isolation of either PRV for maintenance or repair.

a. Insta-Valve® 250 by Hydra-Stop® (or approved equivalent valve) shall be used to allow for continuing water service to building 20.

b. Install one new 8” (NV-1) Insta-Valve® 250 by Hydra-Stop® (or approved equivalent) valve into the existing 8” water service line on the upstream side of the existing PRV using the hot tap method.

c. Install one new 8” valve (NV-2) Insta-Valve® 250 by Hydra-Stop® (or approved equivalent) valve into the existing 8” water service line on the downstream side of the existing PRV using the hot tap method.

d. Both valves shall be positioned and installed to allow for isolation of the existing PRV.
