The Contra Costa County Board of Supervisors approved the project plan set and specifications and authorized staff to solicit for construction bids. The County received seven construction bids on March 11, 2021 which ranged in cost from $12,990,000 to $15,975,000. County staff reviewed the bids and found that the lowest responsive bidder was W.E. Lyons Co. at $12,990,000. The bid amount, however, was much higher than the engineer’s estimate of $11,700,000. As a result, Airports staff has been working with the FAA to secure additional funding to move this project to construction. The Board of Supervisors approved a contract with W.E. Lyons Co. at their April 27, 2021 meeting.
The FAA offered two grants for a total of approximately 12,990,000 million dollars for the construction portion of the project. These grants were accepted by the Board on April 27, 2021.
A modular building was delivered on May 3, 2021, to temporarily house JSX during the project construction. W.E. Lyons received a Notice to Proceed for the project on June 7, 2021. The Contractor set up power to the modular temporary terminal. They have installed construction fencing, a contractor trailer, coordinated moving with JSX and AT&T. JSX moved out of the building to the temporary terminal August 24-25, 2021. After solicitation KSA and Hill replaced WSP as the permanent Construction Manager for the project.
W.E.Lyons has completed demolition of the old building, relocation of the sewer main, elimination of the water main under the footprint of the new Terminal, and poured approximately 95% of the footings. Remaining footings were blocked by an AT&T communication line that serves the Tower that is scheduled to be relocated during the night of February 23, 2022. Contractor is proceeding with utility line installation, final grading, steel fabrication, and slab pour in the next few months.
W.E. Lyons has completed all footings for the building. Interior underground plumbing, electrical and other utilities were installed. The slab on grade was poured in two parts on May 11 and May 14. Steel erection started on May 16 and is expected to be completed by the end of May. Some interior items have been identified as long lead times (up to 55 weeks) due to supply chain issues. Project team continues to work together to identify solutions.
