A summary of the contract cost is as follows: Original bid amount: $248,741.00 Actual cost of bid items constructed: $245,141.00 Total change orders: Final contract cost: $30,139.00 $275,280.00 The work necessary for completion of this contract consisted of replacing the Central Library's former outdated HVAC controller system with a new and more energy efficient system; cleaning and pressure testing the existing system; replacing air control dampers; air balancing; sealing the existing air ducts; retro- commissioning the new HVAC controller system; and training for City Staff on operations and maintenance. The final construction contract cost was approximately 10.7 percent above the original bid amount. The actual cost of bid items constructed was less than the original bid amount due to the flexibility and efficiency of the new HVAC controller system where additional temperature sensors were not needed. Nevertheless, the old system needed repair to various components resulting in two change orders which totaled $30,139. The change orders included replacing damaged sensors, repairing insulation, replacing valves, and adding zones to the controller system for more efficient operation and energy savings.
