A motion to approve a Resolution approving Amendment No. 2 with Harris and Associates for environmental consulting services to amend the scope of work, increasing the compensation by $29,720 for a revised not to exceed amount of $393,538, and extending the term to December 31, 2025.
EXECUTIVE SUMMARY:
On January 18, 2022, the City executed an agreement for $261,736 with Harris and Associates to perform design services for the Industrial Wastewater Pump Station Improvements (Resolution No. 22290). On August 8, 2023, through Resolution 22760 Council approved Amendment 1 to the professional services agreement for additional services and to extend the terms of the agreement.
As the design was being finalized, additional staff reviewed and provided comments to the design which required additional scope of work changes. The consultant continued work and provided construction documents. The project was bid on July 16, 2024, and additional assistance will be required from the consultant for construction. An amendment is required to extend the original contract time and to increase the total compensation to $393,538.
BACKGROUND:
The City of Salinas owns and operates an Industrial Wastewater Collection and Conveyance System (IWCCS) which takes agricultural process water from twenty-six (26) industrial users. The system is comprised of network of piping, an industrial wastewater pump station (IWWPS), and the industrial waste treatment facility (IWTF). The IWWPS is located on Airport Boulevard in southeast Salinas and consists of a wet well and three underground pumps which convey industrial wastewater to the IWTF for processing. The City is conducting structural evaluation and facility upgrades that will ensure not only structural longevity of the pump station but also allow for increased flow capacity and redundancy.
On January 18, 2022, the City Council authorized an agreement for $261,736 with Harris and Associates to perform design services for the Industrial Wastewater Pump Station Improvements (Resolution No. 22290).
Over the course of preparing the preliminary design documents staff was made aware of certain tasks that are required that were not in the original scope of work. These included additional design of a proposed permanent standby generator, generator pad and vault structure; additional flow monitoring; additional hydraulic analysis; site surveying to identify existing easements; corrosion protection assessment; and costs associated with time extensions. On August 8, 2023, through Resolution 22760, Council approved Amendment 1 to the professional services agreement. The additional scope represented a net increase of $102,082 to the original agreement resulting it a total amount of compensation to be paid under the contract of $363,818.
As the plans were being finalized, new City staff assigned to the division reviewed and provided comments to the design that required additional changes to the construction documents. These changes required modification of the plans, cost estimate and specifications. Changes were made by the consultant but required additional effort. The additional scope for Amendment No. 2 represents a net increase of $29,720.
The project was bid on July 16, 2024, and additional assistance will be required during construction. The original contract expired on December 31, 2023. An amendment is required to amend and restate the agreement to increase the contract time to December 31, 2025, and to increase the total amount of compensation to $393,538.
