1600103 - BID SET - DRAWINGS - VOL 2_signed.pdf

This file is a signed bid set containing drawings for Volume 2 of the Sanitary and Storm Systems upgrade project at the National Museum of Natural History (SF Project No. 1600103). The drawings represent the technical design documentation dated December 5, 2025, that form the basis for the construction contract, which the Smithsonian Institution estimates will exceed $10 Million as a fixed-price award. The drawings detail the installation requirements for new sanitary and stormwater piping systems throughout the Museum Main Building, East Wing, and West Wing, including routing specifications designed to protect sensitive areas such as exhibit halls and collection storage spaces by avoiding ceiling passages where possible.

The technical drawings provide the construction specifications and detailed layouts necessary for contractors to execute the infrastructure replacement work while maintaining extreme care for the museum's collections, exhibits, and historic architectural features. The project scope includes piping installation and rerouting, abandonment procedures for existing infrastructure, selective removal and disposal of old piping in compliance with environmental and structural safety standards, and lead and asbestos abatement in affected demolition areas. This bid set represents the contractual design baseline against which all offerors must prepare their technical and cost proposals for the Smithsonian Institution's evaluation and selection of the successful contractor.
