Bid

The word "bid" carries meaningfully different definitions depending on where you are in the world — and in U.S. construction specifically, it applies to a narrower slice of the competitive process than most international practitioners expect.
Bid in U.S. Construction
In the United States, a bid is a fixed-price offer submitted by a general contractor in response to 100% complete construction documents. It is a price-driven exercise owned by the estimating department, not the marketing or business development function. The GC reviews drawings and specifications, quantifies scope, and submits a lump-sum or unit-price number by a defined deadline.
On public work, this process is tightly regulated. The Federal Acquisition Regulation (FAR) Part 36 governs federal construction procurement, and individual state procurement codes govern state and municipal projects. The award goes to the lowest responsive and responsible bidder. There is limited room for qualitative differentiation; the number is the submission.
Design services operate under an entirely separate framework. The Brooks Act (1972) prohibits the federal government from competitively bidding architect and engineer services on price. Selection must follow Qualifications-Based Selection (QBS), initiated through an RFQ or RFP evaluated on qualifications, experience, and approach. Most states have adopted parallel statutes. The practical consequence: calling an RFP response for design services a "bid" is technically incorrect under U.S. law, even though the term is used casually in the industry. For AEC marketing and BD professionals pursuing design work, the hard-bid process is largely not their domain.
How "Bid" Is Used Outside the U.S.
In the United Kingdom, Australia, Canada, and much of continental Europe, "bid" functions as the umbrella term for any formal competitive submission. What Americans call a proposal, an RFP response, or a pursuit is simply a bid in these markets, regardless of whether it is price-driven or qualifications-driven.
The terminology cascade follows accordingly. A bid manager in the UK holds a role equivalent to a proposal manager or pursuit lead in the U.S. Bid writing means proposal writing. A bid library is a content library. The Association of Proposal Management Professionals (APMP) is widely recognized in international markets as the professional body for bid and proposal management, and its certifications are common credentials for practitioners working under the broader definition.
This creates real friction when firms operate across borders or bring on internationally trained staff. A UK bid manager hired into a U.S. firm may find that the role they were recruited for does not map to the title they held, because the scope, the deliverable, and the internal ownership are structured differently.
Why the Distinction Matters for AEC Teams
Firms expanding internationally, acquiring UK or Australian practices, or integrating global talent encounter organizational structures and workflows built around the broader definition of bid. Team titles, reporting lines, and process documentation will reflect that framing, and reconciling them with U.S.-based structures requires deliberate alignment.
The distinction also shapes tool selection in a direct way. Hard-bid construction work requires estimating software built for quantity takeoff and cost modeling. QBS design pursuits require a different infrastructure: pursuit tracking, content management, institutional knowledge capture, and interview preparation. Kantiv is built for that second environment, supporting the qualifications-based pursuit process that governs design services in the U.S. and its equivalents in international markets.
