About this file
This document package includes construction drawings and specifications for concrete and joint repairs to the Second High Reservoir in Washington, DC. The U.S. Army Corps of Engineers, Baltimore District is soliciting fixed-price bids to implement upgrades and improvements including replacement of the brick Sample Building, replacement of the 24-inch drain line, installation of mechanical mixers and communication antennas, addition of a roof drainage system, and replacement of the perimeter fence. The work must be completed during a restricted outage period to minimize disruption to the water supply system serving over one million people. Drawings S-09 provide repair details for concrete spalls, expansion joints, and construction joints between walls and slabs. Replacement of deteriorated materials, sawcutting, doweling, and application of waterproof membranes, epoxy, and injection grout are specified.
