Pillar 01 · qualitative & RFP bidding
Win the scored bid.
When the award is decided on quality and approach, the proposal is the product. This pillar covers how scored bids are evaluated — and how to write to the criteria that actually move the decision.
The short answer
What does it mean to win a scored bid?
A scored bid is won on the page, not the price. Evaluators rate your methodology, team, and approach against published criteria and weightings. Winning means answering what those criteria reward — in the evaluator's own language and order — while staying fully compliant. The bid that mirrors the scoring sheet, and reads like it was written for the evaluator, wins.
The authority behind it
Why the scoring sheet is binding on the owner
Scored bidding in Canada is not a matter of the owner's goodwill — it rests on settled law and standard documents. These are the sources the discipline comes from.
- The Contract A / Contract B doctrine — established by the Supreme Court of Canada in R. v. Ron Engineering & Construction (Eastern) Ltd. (1981). Submitting a compliant bid forms "Contract A," a preliminary contract binding both sides to the rules published in the tender. The construction contract itself is "Contract B," formed on award. This is why an evaluator cannot quietly depart from the criteria once they are published.
- The owner's duty on compliance — in M.J.B. Enterprises Ltd. v. Defence Construction (1951) Ltd. (1999), the Supreme Court of Canada held that a tender call carries an implied obligation to accept only a compliant bid. A privilege clause reserving the right not to accept the lowest bid does not extend to accepting a materially non-compliant one. Scored evaluation and strict compliance operate together, not as alternatives.
- CCDC standard documents — the Canadian Construction Documents Committee publishes the standard forms most Canadian tenders are built on, including the bid bond (CCDC 220) and the performance and labour-and-material payment bonds (CCDC 221 and 222). Knowing which CCDC form a solicitation invokes tells you what a compliant submission must contain.
- Trade-agreement obligations — the Canadian Free Trade Agreement (CFTA) sets out open-tendering and non-discrimination obligations for covered public procurement above stated dollar thresholds, which is why many public opportunities must be posted openly rather than sourced directly. Confirm the current thresholds and coverage in the CFTA text itself, as they are periodically adjusted.
These are general references to Canadian procurement law and standard documents, not legal advice. Case law and its application vary by jurisdiction and by the specific solicitation; confirm anything contract-related with a Canadian construction lawyer.

How-to
How to write to RFP evaluation criteria
The single highest-leverage move in scored bidding: answering in the evaluator's language and order, weighted to what scores.
Q&A
Why do strong bids get disqualified?
Most strong bids lose on compliance, not price — set aside before they're read. How Canada's Contract A rules work, and how to prevent it.
Q&A
How do you beat the presumed favourite?
The incumbent wins on points, not reputation. How a smaller firm outscores the favourite on the published evaluation criteria.
Q&A
When should a bid actually be finished?
Three days before the deadline — not the night it's due. Why the 11pm scramble is where winnable bids quietly die.
