G.H. Forbes Associates Architects Amendment #0006 11/19/2020

The following questions were emailed to the project team. Answers are indicated below in red:

1. Sheet M 2 00 calls out 1-1/2" sanitary drain piping. Piping specifications call for all sanitary drain piping to be cast-iron hub and spigot construction. Cast-iron hub and spigot pipe and fittings are not manufactured in 1-1/2" diameter, 2" is the smallest diameter available. We suggest revising the piping specifications or changing the size of the pipes. GSA’s 2018 P100 allows hubless cast iron pipe and fittings with fittings conforming to ASTM A 888 with heavy duty couplings complying with ASTM C1277 and ASTM C1540. Provide 1-1/2” hubless piping, conforming with these requirements. Refer to attached Peter Basso Associates write-up, revised drawing M-701 and specification 22 13 16.

2. Plumbing Plan Note # 14 calls for 3/4" Condensate Drains for AC units. M 6 02 Trap Dimension Table Note B says 1" Minimum for condensate drains. Please clarify intention regarding condensate drain sizes. Provide ¾” condensate piping to all AC units.

FOR OFFICIAL USE ONLY

Do not remove this notice Properly destroy documents when no longer needed

3.9 FIELD QUALITY CONTROL

A. During installation, notify authorities having jurisdiction at least 24 hours before inspection must be made. Perform tests specified below in presence of authorities having jurisdiction.

1. Roughing-in Inspection: Arrange for inspection of piping before concealing or closing-in after roughing-in and before setting fixtures.

2. Final Inspection: Arrange for final inspection by authorities having jurisdiction to observe tests specified below and to ensure compliance with requirements.

B. Reinspection: If authorities having jurisdiction find that piping will not pass test or inspection, make required corrections and arrange for reinspection.

C. Reports: Prepare inspection reports and have them signed by authorities having jurisdiction.

D. Test sanitary drainage and vent piping according to procedures of authorities having jurisdiction or, in absence of published procedures, as follows:

1. Test for leaks and defects in new piping and parts of existing piping that have been altered, extended, or repaired. If testing is performed in segments, submit separate report for each test, complete with diagram of portion of piping tested.

2. Leave uncovered and unconcealed new, altered, extended, or replaced drainage and vent piping until it has been tested and approved. Expose work that was covered or concealed before it was tested.

3. Roughing-in Plumbing Test Procedure: Test drainage and vent piping, except outside leaders, on completion of roughing-in. Close openings in piping system and fill with water to point of overflow, but not less than 10-foot head of water.

From 15 minutes before inspection starts to completion of inspection, water level must not drop. Inspect joints for leaks.

4. Finished Plumbing Test Procedure: After plumbing fixtures have been set and traps filled with water, test connections and prove they are gastight and watertight. Plug vent-stack openings on roof and building drains where they leave building. Introduce air into piping system equal to pressure of 1-inch wg. Use U-tube or manometer inserted in trap of water closet to measure this pressure. Air pressure must remain constant without introducing additional air throughout period of inspection. Inspect plumbing fixture connections for gas and water leaks.

5. Repair leaks and defects with new materials and retest piping, or portion thereof, until satisfactory results are obtained.

6. Prepare reports for tests and required corrective action.

E. Test force-main piping according to procedures of authorities having jurisdiction or, in absence of published procedures, as follows:

SANITARY WASTE AND VENT PIPING 22 13 16 - 9

FOR OFFICIAL USE ONLY

Do not remove this notice Properly destroy documents when no longer needed

1. Leave uncovered and unconcealed new, altered, extended, or replaced force-main piping until it has been tested and approved. Expose work that was covered or concealed before it was tested.

2. Cap and subject piping to static-water pressure of 150 psig, without exceeding pressure rating of piping system materials. Isolate test source and allow to stand for four hours. Leaks and loss in test pressure constitute defects that must be repaired.

3. Repair leaks and defects with new materials and retest piping, or portion thereof, until satisfactory results are obtained.

4. Prepare reports for tests and required corrective action.
