BACKGROUND INFORMATION: The contract was awarded to Diede Construction, Inc., of Woodbridge, in the amount of $2,492,000, on February 18, 2015. The contract has been completed in substantial conformance with the plans and specifications approved by City Council on November 6, 2013. The Phase 2 project included office space renovation to relocate Parks, Recreation and Cultural Services and Fire Administration to the City Hall Annex building. The project included new public lobbies, public counters, ADA access, ADA staff bathroom facilities, lighting, communications, space conditioning, and associated staff support areas (Exhibit A). The renovated area is approximately 6,000 square feet. The project also included several items to improve services to the City Hall Annex building, as well as the Civic Center complex. These improvements include a new emergency generator, installation of new main electrical switchgear, relocating the data server and telephone rooms from the basement to the first floor, infrastructure supporting future relocation of the radio room to the first floor, and installation of a new chiller unit to serve the City Hall Annex, Finance Department, Fire Station 1 (first floor), Carnegie Forum and City Hall. The contract duration was 180 calendar days and the contract was completed within 180 calendar days. Fire Administration occupied their space on November 25, 2015 and the Parks, Recreation and Cultural Services Department occupied their new space on December 7, 2015. The final cost of the project was $2,866,433. The difference between the original contract amount and final contract was due to six change orders totaling $374,433, or 15 percent of the original contract amount, to address mostly unknown conditions associated with a building constructed decades ago. The changes included: Change Order No. 1: included demolition of existing heating, ventilating, and air conditioning (HVAC) ducting to permit installation of new sewer, water, and electrical pipelines, re-routing of existing first floor and basement plumbing lines, and various other items ($41,842). Change Order No. 2: included installation of steel angle at block openings, re-routing existing second floor plumbing lines, and various other items to coordinate the installation of new work items with existing building utilities. The work also included the grouting of existing wall voids and enlarging wall openings for HVAC equipment and exhaust fans ($64,319).
