OPUS was the Prime Contractor working directley for GWL on this chilled water upgrade project. Our scope included the demo and removal of the existing Chiller, Cooling Tower, Pumps, Heat Exchanger. We then replaced all with new and coordinated chemical treatment. Opus self-performed all demo and new piping, duct-work modifications, all power and mechanical wiring, as well as a very detailed one-day crane lift to remove, dispose and hoist all new. This required a City Street Closure Permit, police and traffic control. Subcontractors to Opus included BAS Controls, insulation, civil, hydronic balancing, and chemical treatment. The challenge was met to replace all in a timely manner while maintaining minimal disruption to the Building Operation.
