How to bid on Seattle’s On-Call Solid Waste Data Analysis and Economic Services

What Seattle is seeking

The City of Seattle is seeking proposals for on-call solid waste data analysis and economic services. The notice does not describe the detailed scope or quantities, so review the project materials in the procurement portal before deciding whether to bid.

This may interest firms that provide professional data analysis or economic services relevant to solid waste.

Deadline and questions

Proposals are due November 13, 2026, at 4:00 PM ET. The notice does not provide a separate question deadline or question-submission time.

The full description says questions must be submitted through the e-procurement portal, but its question deadline fields are not filled in. Check the project page for the current question instructions and any addenda.

Who may be a good fit

Consider this opportunity if your firm offers professional solid waste data analysis or economic services and can provide on-call support. Since the notice does not give a detailed scope, use the project materials to confirm that your capabilities match the City’s needs.

How to access and respond

Open the opportunity through “View original source” to reach it on OpenGov Procurement. A brief security check may appear the first time; let it finish so the project page can load.

Sign in or create a free vendor account to download plans, ask questions, join the planholders list, and submit your response. OpenGov also provides addenda notices.

Prepare a clear, competitive proposal

Read the project materials and addenda carefully before preparing your response. Follow the stated submission instructions and organize the proposal so evaluators can readily see how your firm’s experience and methods relate to the requested services.

Submit through the portal well before the deadline, and check that the response is complete and successfully submitted. Use the portal’s question process to clarify anything important that the project materials leave unclear.
