This document consists of architectural and engineering drawings for campus infrastructure projects involving underground water piping systems and mechanical nodes.

The drawings depict three primary components: (1) a Central Campus Underground Water Piping Vault showing an existing node distribution pit with enlarged renovation plans, including connections to Buildings B102, B108, B101, B100, B104, and B105, with annotations identifying faulty valves requiring replacement and core bore locations for new pipes; (2) the B104 Library Lower Mechanical Node schematic showing heating and water distribution connections between the heating plant (B110) and the central campus vault, with isolated hot water return (HWR) and hot water supply (HWS) valves; and (3) the B105 Business South Lower Mechanical Node diagram illustrating similar mechanical systems and piping connections between the central campus vault and Building B103. The drawings are technical in nature and appear to serve as reference documents for capital improvement work involving plumbing system renovations, valve replacements, and infrastructure modernization across multiple campus buildings. Key deficiencies identified include faulty valves in the central piping vault requiring corrective action.
