The on-call construction management services shall include, at a minimum: project management, safety management, contract administration, document control, change management, inspection services, quality assurance, quality control, schedule management, materials testing, labor compliance, constructability reviews, and cost estimating. 

On-Call Construction Management Services.

Background

West Basin utilizes on-call construction management services to deliver Capital Improvement, Rehabilitation and Replacement, Customer Development and Operations Support projects in a cost efficient and effective manner. The existing On-Call Construction Management Services Agreements will expire on mid-2026; therefore, new professional services agreements will be needed.  West Basin’s mission is providing a safe and reliable supply of high-quality water to its customers, and to fulfill its mission, West Basin has identified numerous Capital Improvement and R&R projects scheduled for completion in the next three years. It is estimated that the total value of Construction Management services rendered under the on-call agreements will be approximately $3,000,000.

It is anticipated that up to five (5) Firms will be awarded with a contract to provide on-call construction management services on a task order basis to help implement these various projects. The term of this on-call contract will be three years, ending in June 2029.

Each project shall be negotiated separately and be awarded as a task order, complete with a scope of work, fee estimate, schedule, and project team organization chart, on an as-needed basis.  The Consultant must provide a proposal in response to each solicitation from the West Basin project manager. Failure to provide proposals may result in the Consultant being found to be in breach of the Agreement. Details of this provision can be found in Exhibit A.

Task orders under the on-call agreements will be issued as follows:  
•    West Basin will provide a scope of work for the task order to each Consultant. 
•    Consultants will submit abbreviated proposals for each task order to identify the fee estimate, construction management approach, construction management team members, Consultant qualifications, design/project schedule, and electronic document control system. 
•    Fee estimates shall include hourly labor rates for each proposed team member, subtotals and totals for labor, other direct costs (ODCs), and sub-consultant costs by task as well as total costs for each project. 
•    Task orders will be awarded to a Consultant based on evaluations of proposals for completeness, qualifications, and best value. 
•    Consultant shall not proceed with the task order until West Basin issues a Contract Release or Task Order Release. 
•    West Basin reserves the right to negotiate the fee for each task order with the Consultant.  
•    With respect to construction management task(s) and depending on the size of a specific project, West Basin reserves the right to waive certain tasks mentioned in the Scope of Work (Exhibit A).
•    Consultant’s fee schedule shall be in effect upon execution of contract and limited to maximum increases of 3% per calendar year for continuation of the contract for subsequent years.  The Consultant shall include a rate schedule for calendar years 2026, 2027, 2028 and 2029 in its proposal.  These rate schedules shall be incorporated into the contract documents and remain in effect for the contract term. The rate schedules included in the Respondent’s proposal shall be used as the basis for fee estimates included in each task order proposal.
