P-101 Building 18B Plumbing Sanitary Line Upgrades..pdf

This document is a construction drawing for building plumbing system upgrades. The drawing depicts the replacement of a 4-inch sanitary pipe serving toilet rooms 18-138 and 18-118 in Building 18B, along with associated demolition, piping installation, concrete work, and flooring restoration. The work areas encompass toilet rooms 18-138 and 18-118, corridor 18-101, and either storage room 18-122A or 18-122.

The document provides detailed specifications for work in three distinct areas: Toilet Room 18-138, which requires existing tile flooring demolition, removal of existing sanitary piping and connections, installation of new sanitary piping, pouring new concrete, and tile flooring restoration; Corridor 18-101 and Storage Rooms 18-122A or 18-122, which involves similar demolition and restoration procedures; and Toilet Room 18-118, which requires existing tile flooring demolition, old piping removal and TC-in to TC-main line replacement, fixture connection adjustments, new concrete pouring, and tile flooring restoration to match existing materials. The drawing indicates that the 4-inch sanitary pipe location shown is approximate only and that the contractor bears full responsibility for field verification and identifying the actual pipe location before commencing related work, with required clarification to the Office of Construction and Facilities Management before proceeding.
