Why Proposal Comparison Is Harder Than It Looks

Contractor proposals for the same project are rarely apples-to-apples comparisons. Different contractors make different assumptions about scope, materials, methods, and inclusions. A proposal that appears to be lower in price may simply be excluding items that the other proposals include — items that will need to be added back through change orders once the project is underway.

The challenge is compounded by the fact that proposals are often written in contractor-friendly language — clear about what is included, vague about what is not. An owner who does not know what to look for may not realize that a proposal excludes permit fees, disposal costs, or specific materials until those items appear as change orders.

Effective proposal comparison requires a systematic approach — not just a comparison of bottom-line numbers, but a line-by-line review of what each proposal includes, what it excludes, and what assumptions it makes.

Scope Alignment: Are You Comparing the Same Thing?

Before comparing prices, confirm that all proposals are responding to the same scope of work. If the scope was not clearly defined in the request for proposals, different contractors may have made different assumptions about what the project includes.

Scope alignment requires reviewing each proposal against the project scope and identifying any differences. Common scope differences include: the extent of demolition or removal work; the specification of materials (grade, brand, or type); the inclusion or exclusion of site preparation, cleanup, and disposal; the treatment of existing conditions that may require remediation; and the handling of permit applications and inspections.

If proposals are based on different scope assumptions, they cannot be meaningfully compared until the scope differences are resolved. This may require going back to each contractor with clarifying questions and asking for revised proposals based on a consistent scope.

What Is Included and What Is Not

Every proposal has exclusions — items that are not included in the price. Some exclusions are standard and reasonable; others are significant and should be flagged.

Common exclusions to watch for include: permit fees (which can be substantial on larger projects); utility connection fees; testing and inspection fees; hazardous material remediation (if existing conditions are unknown); landscaping and site restoration after construction; and temporary facilities such as fencing, portable toilets, and dumpsters.

Exclusions are not necessarily a problem — they may reflect a reasonable allocation of responsibility between the owner and the contractor. But they must be identified and accounted for in the total project cost estimate. A proposal that excludes permit fees is not cheaper than one that includes them; it is simply presenting the cost differently.

Ask each contractor to provide a written list of exclusions and clarifications. This forces the contractor to be explicit about what is not included and gives the owner a basis for comparison.

Price vs. Value: What the Number Does Not Tell You

The price in a contractor proposal is one data point. It does not tell you about the contractor's experience with similar projects, their track record for completing projects on schedule, their financial stability, their approach to change orders, or the quality of their work.

A contractor who consistently delivers projects on time and within budget — even at a higher initial price — may represent better value than a contractor who bids low and then makes up the difference through change orders, delays, and disputes.

Evaluating value requires information beyond the proposal itself. References from owners of similar projects are the most reliable source of information about a contractor's performance. Ask for references specifically from projects similar in type and scale to yours, and call them. Ask about schedule performance, change order frequency and reasonableness, communication, and whether the owner would hire the contractor again.

Licensing and insurance verification is essential. In Florida, contractors performing work above certain thresholds must be licensed by the Florida Department of Business and Professional Regulation. Verify that each contractor holds the appropriate license for the work being proposed, and confirm that their insurance coverage — general liability and workers' compensation — is current and adequate.

Questions to Ask Before Deciding

Before making a final decision, ask each contractor a consistent set of questions. The answers — and the manner in which they are given — provide important information about the contractor's approach and reliability.

Key questions include: What is your experience with projects similar to this one? Who will be the project superintendent, and how much of their time will be dedicated to this project? What is your current workload, and how does this project fit into your schedule? How do you handle unforeseen conditions that arise during construction? What is your process for change orders — how are they identified, priced, and approved? What is your payment schedule, and what are the conditions for each payment?

The answers to these questions should be consistent with the proposal and with the contractor's references. Inconsistencies — a contractor who claims extensive experience but cannot provide references, or who describes a rigorous change-order process but whose contract contains broad allowances for additional charges — are warning signs.

Documentation and Contract Terms

The proposal is not the contract. Before work begins, the scope, price, schedule, payment terms, and change-order process should be documented in a written contract that both parties sign.

A well-drafted contract protects both the owner and the contractor by clearly defining what each party is responsible for. Key contract provisions include: a detailed scope of work that incorporates the proposal and any clarifications; a project schedule with milestones and a completion date; a payment schedule tied to project milestones rather than calendar dates; a change-order process that requires written authorization before additional work is performed; provisions for dispute resolution; and insurance and indemnification requirements.

For significant projects, having the contract reviewed by legal counsel before signing is advisable. The cost of a contract review is small relative to the cost of a dispute over a poorly drafted contract.

Documentation does not end at contract signing. Throughout the project, maintain records of all communications, change orders, payment requests, and inspection reports. These records are essential if a dispute arises.
