Body
SUMMARY:
In March 2017, Walbridge was selected under Request for Qualifications 10-17 (Construction Management at Risk Services) to provide Pre-Construction services, in the amount of $94,923, to include design review and construction cost estimating. Final construction documents are complete and Walbridge has now provided a GMP to construct new facilities at the Clearwater Gas System (CGS) complex located at 400 N Myrtle Ave, Clearwater. Engineering will manage the CM at Risk construction contract for this project.
The current CGS buildings are over 35 years old and no longer meet the needs of the department and have surpassed their lifespan. The proposed redevelopment will include a two-phase construction schedule. The first phase will include a Propane office/storage facility on the south end of the property, Welding shop and a three-story Main building housing Administration, Operations, Sales, Warehouse and records storage. The main building will be hardened to withstand a category 5 hurricane (i.e., withstand 3-second wind gusts of up to 223 mph along with enhanced impact resistance for windborne debris). The second phase will include storage/support facilities and parking lots.
Overall, the CGS redevelopment project will consists of seven new buildings:
#1 - Propane facility (small office and tank storage/refurbishment)
#2 - Propane truck parking structure
#3 - Gas pipe (coil type) storage garage
#4 - Gas pipe (40ft stick type) storage garage
#5 - Welding Shop
#6 - Energy Plant (Natural Gas Air conditioners/Chillers and standby generator)
#7 - Main building (Administration, Operations, Sales and Warehouse)
The Energy Plant will consist of three natural gas powered chillers, one standby generator and a 65kW electric generator that will provide continuous baseload power for the CGS complex, in lieu of using Duke Energy electric. The differential costs association with using natural gas technologies will be funded by our Energy Conservation Allowance budget.
Construction is scheduled to begin in January 2018 and completed in April 2020. Current administrative and operation facilities will remain in place during Phase I construction.
