Question 3: Contract Administration — the bid package, competitive bidding, and unbalanced bids (20 marks)

Part (a) — the components of a bid package. The bid (tender) package is the complete set of documents the owner issues to bidders, and every document in it becomes a contract document on award, so its assembly is a contract-administration act rather than a clerical one. It opens with the Invitation to Bid and the Instructions to Bidders, which fix the closing time and place, the bid irrevocability period, the format of the submission, the addenda procedure and the owner's privilege clause. The Form of Tender follows: a stipulated (lump) sum for building work, or a schedule of unit prices against estimated quantities for civil and municipal work, together with separate prices, alternative prices and the list of proposed subcontractors and suppliers. Bid security is next — normally a bid bond of ten percent of the tender sum or a certified cheque, plus a consent of surety undertaking to issue a fifty percent performance bond and a fifty percent labour and material payment bond on the CCDC 220 and 221 forms. The package then carries the substantive documents: the proposed Agreement (CCDC 2 stipulated price in Canada, or the MMCD form for municipal servicing), the General Conditions and any Supplementary Conditions, the Specifications organised by MasterFormat division, the Drawings, and all Addenda issued during the bid period. Finally it includes the information a bidder needs to price risk: the geotechnical report and existing-conditions data (usually furnished "for information only", with the interpretation risk expressly allocated), the milestone dates and liquidated-damages clause, insurance and WorkSafeBC clearance requirements, and any prequalification, safety-record or local-content submissions.

Part (b) — the competitive bidding process. Public work is advertised openly — on BC Bid, MERX or the agency's own portal — or, where the agency has prequalified a list, issued by invitation to that list. A mandatory or optional site meeting follows, and from that point every bidder question is answered in writing by addendum issued to all bidders, so that no bidder holds information the others do not. Bids close at the stated hour, are opened publicly and the totals are read aloud. Canadian law then treats the process itself as contractual: under the Contract A / Contract B doctrine established in R. v. Ron Engineering (1981) and refined in M.J.B. Enterprises (1999) and Martel Building (2000), submitting a compliant bid forms Contract A, which binds the bidder not to withdraw during the irrevocability period and binds the owner to treat all bidders fairly and to accept only compliant bids — a privilege clause lets the owner reject all bids but does not license it to accept a non-compliant one. Evaluation therefore proceeds in a defensible order: check bid security and signatures, check compliance with the mandatory requirements, verify the arithmetic and reconcile extensions against unit prices, then assess the low bidder's responsibility — bonding capacity, licensing, safety record, past performance, key personnel and current workload. Award is by notice to the successful bidder, followed by execution of the Agreement, delivery of performance and payment bonds and insurance certificates, and release of the other bidders' security.

Part (c) — screening unbalanced bids and selecting the winner. A bid is unbalanced when its total is competitive but its unit prices do not reflect the actual distribution of cost. Two forms matter. A front-end loaded bid prices early items — mobilisation, clearing, excavation — above cost and late items below cost; the total is unchanged but the contractor is financed by the owner, and if the contractor defaults at mid-contract the owner has already overpaid for the work in place. A mathematically unbalanced bid exploits suspected errors in the tendered quantities, pricing high the items the bidder expects to overrun and low those expected to underrun; the bid is lowest at the tendered quantities and dearest at the real ones. Public agencies screen for both with a standard set of tests: compare each unit price against the engineer's estimate and against the average of the other bids, flagging any item outside a stated band (commonly ±25 percent, or more than one standard deviation from the spread); re-total each bid at the engineer's quantities and at a range of plausible final quantities to see whether the ranking survives; discount each bid over its expected payment schedule, since a front-loaded bid has a higher present value to the contractor than its face total; cap mobilisation as a percentage of contract value and pay it over several progress certificates; and require the bidder to justify outlier items in writing. An imbalance that is merely arithmetic may be accepted; a bid that is materially unbalanced — one where the imbalance means the agency can no longer be confident of the lowest ultimate cost, or exposes it to a defaulting-contractor loss — is rejected. The winner is then the lowest compliant, responsible and balanced bidder, or, where a request for proposals with published weighted criteria was used, the highest-scoring proponent on those published criteria and no others.
