| Referral History: |
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 worked with the FAA to secure two grants totaling $12,999,000 with the FAA to move this project to construction. The Board of Supervisors approved a contract with W.E. Lyons Construction Company (Lyons) at their April 27, 2021 meeting.
A modular building was delivered on May 3, 2021, to temporarily house JSX during the project construction. Lyons received a Notice to Proceed for the project on June 7, 2021.
Lyons has completed all portions needed for the relocation of the watermain that was within the new building’s footprint. Additionally, they have completed installing storm drain pipes and relocating the sewer main that was also in conflict with the new building’s footprint. 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. |
| Referral Update: |
Lyons has completed the steel erection, made good progress on interior rough framing, electrical, plumbing, and HVAC.
The September 2022 update to the Airports Committee reported that the building would require a private sewer lift station, which was not part of the original bid set of plans. Since that time, staff worked with its design team along with Contra Costa Central Sanitation District (Central San) to develop a plan that eliminated the need for a lift station. In terms of construction costs, along with ongoing operations and maintenance costs, this change was a significant benefit to the Airport. Such a change this late in the project was only possible through Central San’s responsiveness and technical acuity.
While progress continues on the project, the delays that occurred during the initial phases of the project have significantly pushed the completion date of the building. The contractor’s original base schedule showed the building being completed in December of 2022. The most current schedule shows the project being completed in August of 2023, at least eight months behind schedule. Such schedule impacts will also result in increased soft costs (i.e., facility rentals, construction management services, architectural services, etc.) that the Airport budget must cover.
Beyond Lyons’ change order requests related to delay impacts, numerous other change orders have been submitted that are requiring Airports staff’s time to evaluate and negotiate with Lyons’ ownership.
While progress has been made on the project since the last update, the rate at which work is being done, along with the number of rain days, the August 2023 completion date may be in jeopardy. Because of a significant delay in the delivery of the building’s windows, getting the structure completely dried-in has yet to happen.

|
| Recommendation(s)/Next Step(s): |
| Lyons will continue to move forward with constructing the building. The construction management/ownership team will continue to work diligently with Lyons’ ownership to resolve the lackluster progress and subsequently deal with the various change orders received by the County. |
| Fiscal Impact (if any): |
There is no impact to the General Fund, all project costs will be paid through the Airports Enterprise Fund, inclusive of bond money and reserve amounts. The FAA has provided two grants for a total of approximately $12,990,000.
Through January of this year, the contract value remains at approximately $14.4M, and to date, Lyons has submitted approximately $1.2M in change orders, that the County has yet to agree to. Additionally, because the project will take 7-8 months longer than anticipated, the Airports budget must cover increased costs for construction management and architectural oversight. To that end, the Board approved approximately $925,000 this past December to cover the necessary contract amendments. |
