About this file

This document is a construction drawing for plumbing work at Fleet Readiness Center East, Building 4035 basement. The drawing is identified as Plumbing Plan - Construction (P-101), dated 31 AUG 2026, issued for bid, with drawing number 12939831. The project involves two primary tasks: replacing mechanical seals per Detail A1 and repairing pipe penetration seals per Detail A3.

The work requires installation of a new modular pipe sealing system for 4-inch ductile iron and gray PVC pipes that penetrate the sump concrete wall. The mechanical seal replacement specifies removal of existing sealing elements, cleaning of sleeve and pipe surfaces, and installation of a new system with nitrile green rubber seal elements, reinforced nylon polymer pressure plates, and 316 stainless steel hardware, installed per manufacturer's instructions. The pipe penetration seal repair requires removal of existing sealing materials, enlargement of clearance around pipes, surface preparation including filing concrete to a smooth finish, and application of a chemical resistant fluoroelastomeric sealant suitable for chromate and cyanide waste compatibility. A 3/4-inch diameter backer rod is specified for the cavity around pipes. The plumbing floor plan identifies three waste tanks (Acid Waste T-401, Chromate Waste T-402, and Cyanide Waste T-403) with corresponding pipe runs requiring seal work. All dimensions shown are approximate, and field verification is required prior to ordering materials and commencing work. This drawing forms part of Work Order #7516334.
