efficiency and prevent future work on the roof. The cost to install new gable end <br /> windows is anticipated to be $251,783. An additional week of library closure (for <br /> a total of four weeks) is required to install the windows. The work will be <br /> expedited by additional overtime hours. <br /> 8. HVAC Relocation for Maintenance Access <br /> The existing HVAC equipment needs to be relocated to install a maintenance <br /> access. The plans only identified duct work relocation, but a heating element <br /> within the ductwork needs to be relocated which requires the entire system to be <br /> drained and new wiring to be installed. <br /> 9. Re-mobilization and Weather Protection <br /> The windows have temporary weather protections in place and the roof tiles can <br /> not be installed until the windows and stucco are installed. Protective measures <br /> for the windows and roof membrane need to be installed to ensure there is no <br /> damage to the roofing membrane or water intrusion into the building. The change <br /> in the window frames for the seismic bracing and supply chain issues have <br /> caused a delay in the delivery of the contract windows. A further delay is <br /> associated with the delivery of the gable end windows which will take 12 to 16 <br /> weeks after they are ordered. Other areas of the roof also need weather <br /> protection as additional stucco was removed. <br /> Staff recommends retaining $85,000 to cover any additional unforeseen conditions for <br /> the remaining portion of work, which includes the window and maintenance ladder <br /> installations. <br /> The anticipated project contingency and allowance expenditures total $707,000, and the <br /> authorized contingency and allowances total $432,000, leaving a shortfall of$275,000. <br /> Staff recommends increasing the project contingency to $612,000, plus the $95,000 in <br /> contract allowances to cover the anticipated expenditures.
