This project involves the demolition and replacement of key electrical and control system components to support four new pump motors and updated system functionality. The work includes disconnecting, removing, and disposing of all existing cable, conduit, and electrical equipment associated with the project, as well as installing new power distribution equipment for the four new pump motors and a new control cabinet provided by others. Temporary power will be maintained for all HVAC equipment throughout demolition and installation to keep critical systems operational. The project also includes installation of new control wiring for all sensors. Because much of the existing system was undocumented, OS Engineering provided substantial engineering and design support, including extensive research and documentation, to develop a complete and well-defined final solution.
