RESPONSES TO CONTRACTOR QUESTIONS AS OF 7 AUG 08

SOLICITATION NBR FA6656-08-R-0004

Modify/Upgrade Industrial Wastewater Pretreatment Facility, Bldg 309

1. On Drawing P-1 they are asking for 4” Power Vent Category III Stainless Steel Pipe that connects to the Gas Fired Water Heater. I didn’t find any spec on that pipe. Response: any 4” Category III stainless steel pipe for venting applications is acceptable. No minimum thiickness or schedule is required. PVC is not allowed.

2. Also, on Drawing M-2, the top of the page they have heavy outlines three (3) valves but they are not marked as to be removed and replace. Response: The three valves with heavy outlines designated SV-22, MV-5 and MV-6 will not be removed or replaced and are not involved in this project.

3. I would like to know what the specifications are for the Lavatory (Lav-1). There is nothing mentioned under Section 22 40 00. On the drawing (P1) it is listed as a wall hung and nothing more. Please advise. Response: The lavatory is integral with the countertop and is specified as an architectural product in Section 06 61 17, and it is shown on drawing A-1. The wall hung note on P1 is incorrect, as there is not a lavatory plumbing fixture. The faucet to be field mounted in the counter top should be equal to the following: Faucet shall be chrome plated combination supply fitting with grid strainer, 0.5 GPM flow device, aerator, loose key supplies, single lever handle, chrome plated 17 gauge brass P-trap with cleanout plug and arm with escutcheon. American Standard 2385.009 with grid strainer or equal. Amendment forthcoming changing the Plumbing Fixtue Schedule on Dwg P1 from “wall hung” to “counter mounted’ and adding the faucet description to Specification Section 22 40 00.
