BACKGROUND
The Orange County Sanitation District (OC San) Plant No. 2 is protected by an existing chain link fence along the south side of the plant, adjacent to the Talbert Marsh. The 2019 Climate Resiliency Plan identified a need for a new perimeter wall to protect the plant from future flooding, tsunami, and sea level rise threats. In addition, in 2019 the Seismic Evaluation of Structures at Plant Nos. 1 and 2 identified lateral spread as a concern, where soil can slide into the Talbert Marsh during a seismic event. Finally, to better secure our facilities, OC San developed new security standards that includes perimeter wall lighting and camera upgrades.
RELEVANT STANDARDS
• Comply with California Public Contract Code Section 20103.8, award construction contract to lowest responsive, responsible bidder
• Protect OC San assets
PROBLEM
The existing fence along the south side of Plant No. 2 will not protect the facilities from lateral spread or climate threats and does not meet OC San’s security requirements.
PROPOSED SOLUTION
Award a Construction Contract Agreement to replace the perimeter chain link fence along the Talbert Marsh with a cast-in-place concrete wall and engineered footing system.
TIMING CONCERNS
The construction area of this wall overlaps with the construction area of the future Digester Replacement, Project No. P2-128. The digester replacement may be delayed if the construction of this wall is not finished.
RAMIFICATIONS OF NOT TAKING ACTION
The wall will not provide the protection required by OC San’s Climate Resilience plan and will not provide the required site security. The area will also remain subject to lateral spread in a seismic event.

On September 5, 2024, the apparent low bidder, Steve P. Rados, Inc. (Rados) submitted a letter requesting to withdraw its bid and return of its bid security due to clerical error, pursuant to Public Contract Code section 5100 et seq. After consultation with OC San Counsel, Rados was informed that a recommendation would be made to the Board of Directors to approve Rados’ request to withdraw its Bid and for the return of its Bid Bond.
The next two low bidders were evaluated in accordance with the OC San’s policies and procedures. A notice was sent to all bidders informing them of the intent of OC San staff to recommend award of the Construction Contract Agreement to Ames Construction, Inc.
Staff recommends awarding a Construction Contract Agreement to the lowest responsive and responsible bidder, Ames Construction, Inc., for a total amount not to exceed $25,270,000.
