This document is a design and construction specification package for chilled water repairs at the Mississippi River Basin Clock Tower & Annex Complex in Rock Island, Illinois, issued by the US Army Corps of Engineers, Rock Island District.

The project scope encompasses mechanical demolition and installation of new chilled water system components. Demolition work includes removal of existing shut-off valves, buffer tank, cooling coil, and associated piping from the Clock Tower building. New work involves installation of a new chilled water piping system with integrated components including an air separator, glycol fill tank with high-capacity air vent, strainer, shut-off valves, balancing valve, three-way valve, buffer tank, AHU cooling coil, and brazed plate heat exchanger. The mechanical drawings (sheets MD101, M-101, and M-601) detail specific demolition sequences, new component placement in mechanical rooms, proper piping connections and sizing, valve locations, and system flow direction. Key specifications require providing new chilled water piping from existing sump and associated piping, labeling all piping with content and flow direction, ensuring all shutoff valves and components integrate into a complete system, filling the system at project end to operating levels, and connecting new piping to existing pumps. All work must be performed with proper isolation around existing buffer tank, drain provisions, and installation of insulation around new piping and equipment as specified.
