About this file
This is a technical drawing for a chiller support concrete pad installation at Building A69 of the Naval Research Laboratory. The document contains both a plan view and cross-sectional details for the concrete pad construction, drawn at scales of 1/2" = 1'-0" for the plan and 1" = 1'-3" for the section view.
The design specifications indicate an 11'-0" x 14'-0" concrete pad with specific reinforcement requirements, including steel welded wire fabric mesh conforming to ASTM A185. The pad features an 6"x4" x 2.5/2.5 welded reinforcement detail centered to scale, with designated top of grading and wire positioning. Key notes reference coordination with mechanical drawings (M-101) for precise pad location, confirmation of top of pad elevation based on site conditions, concrete specifications requiring 65 air entrainment for exterior exposure, and compliance with ASTM standards for steel reinforcement. The document is marked as controlled unclassified information and includes reference number PW 6860 for Building A69 chiller pad work at the Naval Research Laboratory.
