BACKGROUND
The Engineering Division supports delivery of Capital Improvement Projects (CIP) and ongoing Public Works operations. CIP projects consist of several phases that require diverse engineering expertise from initial planning to construction completion.
Previous on-call agreements for the subject services solicited in 2021 have been extended to allow completion of previously assigned projects and related tasks, but no additional projects are being issued. The remaining work is limited to previously authorized assignments. Currently, some of the in-progress projects may not continue to the next phase without further amendments to existing contracts due to contractual amount limitations.
The City has issued other on-call solicitations for specialized services; however, many contracts are now outdated or are discipline-specific:
Inspection services – last solicited in 2021
Construction/project management – last solicited in 2022 To support efficient project delivery, staff released a new Request for Proposal (RFP) to establish an updated and expanded list of qualified consultants across multiple engineering disciplines, including, but not limited to: street improvements, stormwater, wastewater, water systems, structural engineering, and other fields of expertise such as, environmental compliance, permitting, construction management, and inspections. Furthermore, at any given time, there may be several projects with critical deadlines or other specific obligations and time-sensitive requirements necessitating expertise.
ISSUES/ANALYSIS
An RFP was released on July 3, 2025, through Public Purchase, with proposals due August 5, 2025. Nineteen (19) firms submitted proposals, which were reviewed and scored based on understanding of the scope, proposed approach, and relevant experience and qualifications. Proposals were received from the following firms:

Staff recommends awarding contracts to the six (6) highest ranked firms.
AnGenious Engineering Service, Inc
ERSC
GHD, Inc.
Michael Baker International
Psomas
Transtech Engineers, Inc
Awarding multiple agreements to the highest-ranked consultants provides multiple benefits:
Flexibility & availability: Ensures support when firms are occupied or specialized expertise is needed.
Competition: Encourages responsive and cost-effective services.
Timelier project delivery: Reduces delays in implementing capital and operating projects.
Administrative efficiency: Pre-qualified consultants can be issued task orders quickly without additional lengthy solicitation processes.
Mitigates limited options: If the City is not satisfied with a consultant’s services, a consultant is not available for a project, or contractual limits will not allow for a consultant’s participation, there are still consultants that can be utilized without additional solicitation.
Agreements will have an initial three-year term with two optional one-year extensions. Awarding a PSA does not guarantee task order issuance, or full or partial use of the contract amount. Cost proposals will be requested from firms on the on-call list. Each task order will be issued as needed and negotiated individually. Payments will then be processed based on the actual work performed. Consultants are aware of these terms. On-call contracts are a standard procurement method used by local, regional, and state government agencies including San Bernardino County and California Department of Transportation (Caltrans), allowing efficient access to professional services under pre-established terms.
The subject services are commonly referred to as soft costs and can vary widely from approximately 20%-50% of construction costs dependent upon the project complexity, size, specialized technical expertise, special studies needed (such as environmental studies or traffic studies), right of way, and grant requirements. Typically, the engineering and design services range from approximately 25%-35% of the total project cost. Normally, the more complex the project is, the higher the cost of said services will be. Using 30% for demonstration purposes, a project costing $4.0 million to construct, the subject services would be approximately $1.2 million. These baseline PSA amounts may not be sufficient to see certain projects through the construction phase. Should the need to increase the PSA amounts arise as the projects progress, staff will return to Council.
Presently, there are projects in the current fiscal year’s CIP requiring all or a portion of these services that cannot start until PSAs are in place.
CITY GOAL SUPPORTED BY THIS ITEM
Public Safety - Ensure public safety resources adequately protect our community.
Future Development - Facilitate balanced growth to ensure cohesive community development and pursue economic development.
Capital Improvement - Continually evaluate capital improvement priorities.
FISCAL IMPACT
If approved, each agreement will be for a not-to-exceed amount of $500,000 over the initial three-year term. Actual costs will depend on the issuance of task orders. Funding is available in the adopted FY 2025–26 CIP and Operating Budgets and may include Measure I, Local Transportation Funds, Development Impact Fees, enterprise funds, grants, and other special revenue sources.
ALTERNATIVE(S)
If the on-call agreements are not approved, it would require separate solicitations for each project, causing delays and reduced efficiency.
Provide alternative direction to staff.
