About this file
This document is a technical drawing for a chiller support concrete pad at the U.S. Naval Research Laboratory Building A69. The plan illustrates the structural design and installation specifications for an 11'-0" × 11'-0" concrete pad intended to support chiller equipment. The drawing includes both a plan view (Detail 1) showing the pad layout with dimensions and a cross-sectional view (Detail 2) at a scale of 1" = 1'-8", depicting the pad's depth, reinforcement configuration, and grading details.
Key specifications include a 6"×6"-#20.5 welded wire fabric mesh centered within the concrete pad, with steel wire reinforcement conforming to ASTM A185 standards. The pad sits on a prepared base with top-of-grading and associated drainage provisions. The document notes reference coordination with mechanical drawings (M-101) for precise pad location, confirmation of final pad elevation based on site conditions, concrete finishing requirements per ACI standards, and exterior concrete protection specifications. The project is designated as PW 6860 and is marked as "Controlled Unclassified Information."
