EXECUTIVE SUMMARY Item 1. Contract Change Order No. 4 provides for the replacement of two (2) of the existing air handlers. This equipment and associated work was not identified in the original contract documents and replacement is necessary to make the system fully functional. Item 2. Contract Change Order No. 5 provides for the replacement of duct fire damper equipment that has failed. As a requirement of the Unform Building & Safety Codes, testing was performed on the existing HVAC ductwork and the fire dampers incorporated inside of the ductwork. The results of this testing indicated that four (4) of the existing dampers failed to operate as designed and will require full replacement of these units to comply with current codes. BACKGROUND On September 30, 2021, Council awarded a construction contract in the amount of $549,994.92 to Strategic Mechanical, Inc. for the Replacement of the HVAC System at the FAX Administration Building. The Notice to Proceed was issued with a start date of April 20, 2022, and completion date of October 16, 2022. There have been three (3) Contract Change Orders approved to date totaling $12,649.15, resulting in a revised Contract Price of $656,542.50. There have also been sixty two (62) suspension days granted to allow for the hot weather temperatures to pass prior to switching out HVAC equipment resulting in a revised Contract Completion Date of December 18, 2022. The original scope was determined to be substantially complete on December 18, 2022, and ready for its intended use. During construction it was discovered that the existing air handlers were in need of extensive repairs and had outlived their functional life expectancy and the most cost effective remedy is the replacement of this equipment. This work was not identified in the original contract documents. The Building Code required testing was performed on the existing HVAC ductwork and the fire dampers incorporated inside of the ductwork. It was determined that four (4) of the existing dampers failed to operate as designed and will require removal and replacement of these units to comply with current Code. This work was also not identified in the original contract documents.
