On-call Water Quality Consulting Services

The City of Gresham, Oregon is soliciting proposals for on-call water quality consulting services, with proposals due November 18, 2026. The City intends to select one or two firms under a non-exclusive on-call contract, and the opportunity is listed under Multnomah County, Oregon (FIPS 41051). No set-aside or local-vendor preference appears in the source.

Proposers must submit an executed Request for Proposal certification statement signed by an authorized official, with the firm's Federal Taxpayer Identification number. The certification also requires proposers to certify non-discrimination against minority, women, or emerging small business enterprise subcontractors in subcontract awards, and to certify that the proposal was developed without collusion. Proposals and cost schedules remain valid for sixty days after the due date or any revised submission date, whichever is later, and become part of the negotiated contract.

The scope follows the statement of work in the RFP. The contract template states that the City issues work only by written Authorization to Commence Services, and the City has no obligation to issue purchase orders or use the contract if no requirement exists. Compensation is capped at a maximum amount, with payment structures negotiable among lump-sum completion, monthly time-and-materials progress payments, or deliverables-based payments. The City pays contractors by ACH.

Required insurance includes Workers' Compensation under Oregon Revised Statutes 656.017, Commercial General Liability at a combined single limit of not less than $1,000,000 per occurrence, Commercial Automobile Liability at not less than $1,000,000 per accident, and Professional Liability at not less than $1,000,000 per claim if required. The City and its officials must be named as Additional Insureds, and proof of coverage is due before work begins. The contract term is flexible and renewable for additional one-year terms. The contract incorporates the City's Standard Terms and Conditions and Oregon Statutory Provisions, which supersede conflicting language.
