Title: Description: Calusa ES HVAC Replacement Project No. 1911-8222 This project modification contains the following items: § CCD #3R in the amount of $4,502.00. § Description: Provide additional temporary air conditioning. § Cause: Design Omission § Justification: The engineering estimate for temporary air conditioning capacity (Tons) was not adequate for cooling the main office during the construction. One additional month of temporary air conditioning was required. Item #2 § CCD #20R in the amount of $7,025.00 § Description: Install four additional heat detectors, Rooms 212, 207,106, and 110. § Cause: School District Requested. § Justification: Requested by the Building Department inspector upon final review of the facility. § CCD #21M in the amount of $1,301.00. § Description: Install a double layer of drywall at roof truss and rated wall. § Cause: Unforeseen Condition. § Justification: The roof truss was placed directly over a wall that required a 4-hour fire rating. The concrete wall encased the roof truss and therefore did not comply with the 4 hour fire rating criteria. The engineered solution was the installation of drywall on either side of the wall. § CCD #22 in the amount of $12,805.00. § Description: Correct above ceiling electrical code violations and firewall penetrations. § Cause: School District Requested. § Justification: Corrections required prior to acoustical ceiling installation and Building Department inspections and approvals. § CCD #23 in the amount of $2,133.00 § Description: Remove and replace PVC roof vent line and 3” copper water main. Drain, re-fill and bleed water system. § Cause: Unforeseen Condition. § Justification: Existing vent stack was located too close to the make up air intake. The 3” copper main conflicted with the installation of ductwork. Item #6 § Description: On Calusa Elementary School, the Contractor, Hill York Services, achieved Substantial Completion on January 26, 2004, and requested a Reduction of Retainage from 5% to 1%; the Architect and District staff recommends this reduction. Recommendation: I recommend the School Board ratify Project Modifications in the amount of $27,766.00 and approve Reduction of Retainage from 5% to 1%, for Calusa Elementary School, HVAC Replacement Project, and authorize the Chairman and Superintendent to execute all related contract documents.
