AGENDA TITLE: Accept Improvements Under Contract for City Hall Annex First Floor Phase 2
Interior Remodel Project
MEETING DATE: February 3, 2016
PREPARED BY: Interim Public Works Director
RECOMMENDED ACTION: Accept improvements under contract for City Hall Annex First Floor
Phase 2 Interior Remodel Project.
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).

network room, and other various items requested by City staff ($67,642).
Following acceptance by the City Council, as required by law, the City Engineer will file a Notice of
Completion with the County Recorder's office. The notice serves to inform vendors and subcontractors
that the project is complete and to initiate the 30 -day period to file a stop notice requiring the City to
withhold payments from the prime contractor in the event of a payment dispute.
FISCAL IMPACT: There will be a decrease in facility maintenance costs.
FUNDING AVAILABLE: This project was funded through a combination of funds from CDBG, Public
Benefits, General Fund Capital Outlay, Water Utility, Wastewater Utility and
Electric Utility.
