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 last progress 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 due to the lack of building permits, has significantly pushed the completion date of the building. The contractor’s original base schedule showed the building being completed in December of this year. 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. Given the number of challenges to work through on this project, Airports and Lyons staff have initiated formal partnering sessions through a professional facilitator.

|
| 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 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 October of this year, the contract value is approximately $14.4M, and to date, Lyons has submitted approximately $1.2M in change orders, with an estimated final contract amount as high as $18M. 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, staff will be bringing two contract amendments to the Board in December to cover these costs, anticipated to total approximately $925,000. |
