The Project consists of repairs and improvements to the underground utilidor tunnel network connecting various buildings at College’s campus. The utilidor network contains active and decommissioned steam piping, electrical power distribution, communications cabling, and other utilities. At several locations, underground water and sewer lines pass perpendicularly through the utilidor. The utilidor network suffers from water intrusion caused by the internal steam distribution system, severe condensation on the cast-in-place concrete lids and associated steel decking, chronic leaks at the joint between the utilidor walls and lids, cracks and utility (active and abandoned) penetrations at tunnel walls, and other sources. The primary purpose of this Project is the reduce the quantity of water entering the utilidor network, to replace materials damaged by prior water intrusion, and to protect basement utility spaces served by the utilidor system from flooding.
