RFP Solid Waste Collection Contract

The City of Sammamish, Washington is requesting proposals for citywide solid waste collection services, with first-round questions due December 11, 2026 and proposals due February 17, 2027 at 3:00 p.m. Pacific Standard Time. Proposers must register with City Contact Gen Rubinelli before submitting, and all communications must run through BidNet and the designated City Contact.

The scope covers residential and commercial garbage collection, recycling and organics collection, and processing and marketing of collected recyclables and organics within the City Service Area in King County. The City seeks continuation of most existing collection components under one contract, with substantial upgrades to contract language and service standards per the attached draft Base Contract. Proposers must post a $15,000 proposal security bond with their submission. The City does not require financial statements but reserves the right to request supplemental materials to verify proposer capability.

The contract term is 10.5 years, with a commencement date of January 1, 2029. Pricing covers the base contract and five alternatives: multifamily embedded organics collection, commercial subsidized organics collection, a low-income discount program, electric collection vehicles, and inclement weather credits. Proposers may also submit variations that could reduce costs or improve services. Rates must be stated in 2027 dollars, are subject to Consumer Price Index adjustment before service commencement, and must include labor, equipment, overhead, and profit. The incumbent is Republic Services, whose contract was extended to December 31, 2028 following a 2023 amendment that added the Klahanie neighborhood.

The City will evaluate proposals using a 60-point rate component and a 40-point qualitative review. Second-round questions are due January 15, 2027. Evaluation, interviews, and selection run February through March 2027, contract finalization April through May 2027, and City Council review June through July 2027.
