Renovation of an educational facility in Grand Junction, Colorado. Working plans call for the renovation of a educational facility.

Estimated Construction Cost: $1,378,677 Reference Number 0000335781 Colorado Mesa University (CMU) is seeking bids from qualified mechanical, electrical and plumbing contractors to remove the existing HVAC system in the Fine Arts building and replace with a new heat pump system. The Fine Arts building was constructed over 19 years ago and has been occupied for 12-17 hours each day ever since. Because of its age, many building components are either at or very near the end of their useful life. One such building system includes the heating, ventilating, and air conditioning system, which have reached the end of their useful life and must be replaced. The existing system includes 2 hydronic boilers, pumps, and motors, a large roof top unit (RTU's) and hot water re-heat V.A.V.'s in the interior spaces, and a large gas water heater that provides domestic hot water for the entire building. CMU installed geo exchange piping adjacent to the building during the renovation / expansion of Dominguez Hall in 2007. The existing piping provides the geo exchange resource to Dominguez Hall and will be extended to serve the Fine Arts building with this project. Removing and replacing heat pumps will require existing ceiling grid, speakers, fire alarm strobes, annunciators, and fire suppression systems that interfere with removal and re-installation to be removed/disconnected, stored and re-installed. The contractor chosen to perform the work will have access to the building beginning on Saturday, May 18, 2024, and must complete the work on or before Monday, August 5, 2024. Liquidated damages in an amount equal to $1,500/day will be assessed for each day of delayed completion after August 5th,2024.
