The construction bid evaluation process is where many developers make an expensive mistake: selecting the lowest bid without adequate analysis of what that bid actually covers, who is submitting it, and whether the apparent savings will survive contact with construction. The GC who wins on price and then recovers through change orders delivers neither the value nor the budget certainty the low bid implied.
This guide covers what a rigorous bid evaluation actually involves, how to compare bids on a like-for-like basis, what to look for in the bidder beyond their number, and how to make a GC selection that holds up through construction.
Prepare the Bid Package Correctly
Bid quality is a function of bid package quality. A bid package that is ambiguous about scope, that leaves significant items to GC discretion, or that is based on incomplete construction documents will produce bids that are not comparable, each GC will make different assumptions about what is included, and the apparent spread between bids will reflect those assumptions more than actual cost differences.
Before soliciting bids, ensure the construction documents are sufficiently complete to support accurate pricing. For most multifamily and commercial projects, this means construction documents at or near 100%, not design development, not schematic. Bids based on incomplete documents carry scope risk that is difficult to quantify and expensive to resolve through change orders.
The bid package should include a clear schedule of values structure, the line-item breakdown that the GC will use to price and draw against, so that bids come back in a comparable format. GCs who are allowed to define their own schedule of values will organize costs in ways that front-load draws, obscure their subcontractor allocations, or make line-by-line comparison difficult.
Scope the Bids Against Each Other
Before comparing prices, compare scope. GCs sometimes win bids by omitting line items that competitors have included, by applying allowances where competitors have included actual pricing, or by excluding scope that the construction documents clearly require but that the bid instructions left ambiguous.
Innergy Integral conducts bid leveling on behalf of developers, a systematic review that identifies, for each line item in the schedule of values, what each GC has included and at what amount. Scope gaps and allowance substitutions are identified and quantified, so the developer can evaluate bids on a like-for-like basis. A bid that appears 8% lower than the next competitor may be 3% lower once missing scope is added back.
Common scope items that bidders omit or underprice: utility connections and service upgrades; civil and site work that is described in the specifications but not carried explicitly in the budget; accessibility compliance and code items that are present in the drawings but easily missed in estimating; MEP systems where the specifications are performance-based and the GC has applied a low allowance rather than actual pricing; and temporary conditions, site security, winter protection, temporary utilities, that add up over a long construction schedule.
Evaluate the Bidder, Not Just the Bid
Price is one data point. The GC’s qualifications, financial stability, subcontractor relationships, and track record on comparable projects are the context in which that price should be evaluated.
Relevant project experience. Ask for a list of comparable completed projects, similar type, scale, and structural system, with references. A GC with a strong track record in wood-frame low-rise multifamily may not be the right firm for a concrete mid-rise. A GC whose experience is in commercial construction may not have the subcontractor relationships required for a 200-unit residential project. Match the GC’s experience to the project’s requirements, not to construction generally.
Subcontractor relationships. The GC’s ability to field a complete, qualified subcontractor team on your project is as important as the GC’s own qualifications. Ask which subcontractors they are planning to use for the major trades, mechanical, electrical, plumbing, framing, concrete, and verify that those firms have relevant experience. A GC who wins on a thin budget by using lower-tier subcontractors creates quality and schedule problems that cost more than the bid savings.
Financial stability. A GC under financial stress will struggle to pay subcontractors on time, maintain adequate insurance, and absorb the cash flow gaps that construction projects routinely create. Request financial references from their bonding company and from subcontractors who have worked with them recently. Bonding capacity, the GC’s ability to obtain a performance and payment bond, is a useful proxy for financial health.
Communication and reporting. The GC you select will be your primary construction partner for the duration of the project. Their approach to communication, reporting, and problem resolution matters as much as their price. Ask how they handle change orders, how frequently they report schedule and budget status, and how they have managed situations where their performance has fallen short. The answers reveal a great deal about what working with them will be like.
Structure the Contract Before You Select
The construction contract negotiation should inform the selection, not follow it. When you are evaluating two GCs with similar qualifications and a meaningful price difference, understanding what each is willing to accept in the contract, change order markup, retainage terms, schedule milestones and consequences, closeout provisions, helps you evaluate the true cost of each option.
A GC who bids 5% lower but insists on a 15% overhead-and-profit markup on all change orders and no retainage through project completion may deliver a higher total cost than the GC who bid higher with a 10% change order markup and standard retainage terms. The contract terms determine how budget risk is allocated for the duration of the project.
Innergy Integral negotiates construction contracts on behalf of developers, reviewing the GC’s standard form, identifying provisions that disadvantage the owner, and negotiating terms that protect the owner’s budget and timeline. Common negotiation points: change order markup caps, retainage terms and reduction triggers, schedule incentive and disincentive provisions, notice requirements for change order claims, and the scope of the GC’s warranty obligation.
Making the Selection
The GC selection recommendation Innergy Integral provides to developers combines the bid analysis, the bidder evaluation, and the contract negotiation findings into a clear recommendation with supporting rationale. The lowest bid is sometimes the right selection. It is not always, and the analysis required to know which situation applies is the work of the bid evaluation process.
