Estimating & Biddingaka: RFP

Request for Proposal

In Plain English

An owner's request for contractors to submit full proposals including approach and qualifications, not just a price.

Definition

A request for proposal (RFP) is a procurement document issued by an owner soliciting detailed proposals from contractors or service providers that include technical approach, qualifications, schedule, and pricing. Unlike an invitation to bid, an RFP evaluates factors beyond just price. RFPs are common for design-build, construction management, and specialty services.

Why It Matters in Bidding

An RFP shifts the competition from lowest price to best overall value, so winning means investing real preconstruction effort into approach, staffing, and schedule rather than just sharpening pencils on cost. For estimators and business-development teams, understanding the RFP's evaluation criteria and weighting is critical, because a technically strong but mispriced proposal, or a cheap but weak narrative, can both lose.

Example

Responding to the city's RFP for a design-build fire station, the contractor's proposal detailed its design approach, key personnel, and a guaranteed maximum price rather than a single lump-sum number.

Frequently Asked Questions

An invitation to bid is price-driven and usually awards to the lowest responsive, responsible bidder on a fully designed project. An RFP solicits proposals evaluated on multiple weighted factors, including technical approach, qualifications, schedule, and price. RFPs suit design-build, construction management, and complex projects where best value, not lowest cost, matters.
A strong response typically covers the technical and design approach, project understanding, key personnel and their experience, relevant past projects, a realistic schedule, a safety and quality plan, and pricing in the requested format. Many owners weight non-price factors heavily, so a compelling narrative backed by evidence often outweighs being the cheapest.
Owners often run a two-step process: an RFQ first screens firms on qualifications to build a shortlist, then an RFP invites those shortlisted firms to submit full priced proposals. The RFQ filters who is capable; the RFP determines who offers the best overall value among the qualified competitors.
