Attachment_1_-_As-Constructed_Drawings-Utility_Rehabilitation_plumbing_sheet.pdf

This document contains as-constructed plumbing drawings for the Utility Rehabilitation of the Second Bank building at Independence National Historical Park in Philadelphia, Pennsylvania. The drawings were prepared by the National Park Service and are dated July 16, 2002, with drawing number 1433C450002091O.

The plumbing design includes comprehensive systems for basement, first floor, second floor, and attic levels. Key systems specified include domestic water supply and distribution with new piping routed throughout the building, sanitary and storm sewer lines with connection to existing municipal systems, fire protection water supply with 120-gallon hydropneumatic storage tank and booster pumps, and hot water circulation systems. Equipment schedules detail electric water heaters (models DWH-1 and DWH-2), packaged water booster systems (Duplex vertical pump rated at 30 GPM), and elevator sump pumps. Fixture schedules specify lavatories, service sinks, drinking fountains, water closets, urinals, and shower equipment from manufacturers including American Standard, Elkay, Sloan, and Waterless Co. The drawings emphasize disconnection and removal of existing plumbing systems, with coordination notes for work involving slab cutting and patching. General plumbing notes address verification of existing line locations, proper slope requirements, cleanout placement, and coordination with other trades. Multiple detail sheets provide specifications for pipe sleeves, interior wall penetrations, floor drains, water heater installations, and domestic water service diagrams. The construction documents are indexed across 162 sheets total, with plumbing work represented on sheets P0 through P14 covering symbols, abbreviations, notes, demolition plans, new installation plans, equipment schedules, and site coordination details.
