Construction RFP Guide: What to Include and What to Avoid
Construction RFPs have unique requirements that generic templates miss. This guide covers scope, bonding, safety, subcontractors, and how to evaluate bids beyond price.
A generic RFP template will get you into trouble on a construction project.
The language that works for software procurement does not work for site work. The evaluation criteria that make sense for professional services create the wrong incentives when you are selecting a general contractor. And the questions you skip because they seem obvious are often the ones that generate the most expensive disputes.
This construction RFP guide covers what to include, what to avoid, and how to run a bid evaluation that produces a defensible selection.
Scope of work: specificity is not optional
Vague scope of work language is the primary driver of construction change orders. Every ambiguity in the RFP becomes a negotiation during the project. Contractors who price aggressively on a loose scope know they will recover margin through change orders once the contract is signed.
A good construction scope of work specifies:
- Exact site boundaries and access constraints
- Demolition requirements, including what stays and what goes
- Materials specifications by category, with acceptable substitutions defined
- Phasing requirements and sequence dependencies
- Temporary facility needs (power, water, site office, staging area)
- Coordination requirements with adjacent operations or other contractors
- Owner-furnished materials or equipment, with delivery timing
If your scope has phrases like "contractor to provide all necessary," pause. That language shifts ambiguity to the contractor, who will price for the worst case or price low and negotiate later. Be specific about what you need.
Bonding and insurance requirements
State your bonding requirements in the construction RFP, not after you have selected a contractor. Performance bonds and payment bonds are standard on public projects and many private ones. Requiring bidders to confirm bonding capacity in their response filters out contractors who cannot actually execute the work at the scale you need.
Insurance minimums should be stated as dollar amounts, not as "adequate insurance." Define:
- General liability minimums
- Workers' compensation coverage
- Umbrella policy requirements
- Certificates of insurance timing (before work begins, not before contract signing)
- Additional insured requirements
Some contractors carry lower insurance limits as a cost management strategy. You want to know that before award, not when an incident occurs.
Safety record documentation
Safety record documentation separates compliant bidders from contractors who actually have a safety culture.
Request:
- OSHA 300 logs for the past three years
- Experience Modification Rate (EMR), also called the MOD rate
- A summary of any OSHA citations in the past five years with disposition
- The contractor's written safety program
An EMR above 1.0 means the contractor has had more incidents than the industry average. An EMR above 1.2 should prompt a direct conversation before award. Some owners set a hard cutoff at 1.0 for projects where safety risk is elevated.
Safety documentation requests in your RFP set a tone. Contractors who balk at providing OSHA logs are telling you something.
Subcontractor disclosure
Many general contractors perform a fraction of the actual site work with their own crews. The rest goes to subcontractors, who may or may not meet the standards you evaluated the GC against.
Require subcontractor disclosure in your construction RFP:
- Which trades will be subcontracted
- Whether the GC has existing relationships with proposed subs, or whether they will bid the work out
- Any subcontractors already identified, with their relevant qualifications
- The GC's process for vetting subcontractors on safety and quality
On public projects, subcontractor substitution after award often requires owner approval. Define that requirement in the RFP so it is not a surprise during project execution.
Prevailing wage and union requirements
If your project is subject to prevailing wage laws, say so explicitly in the RFP and provide the applicable wage determinations. Bidders need this information to price accurately. If they miss it and you catch it at contract negotiation, you are either renegotiating or re-bidding.
Union requirements vary by project type, owner type, and geography. If you have project labor agreement (PLA) requirements, state them in the RFP. Contractors who cannot comply with a PLA should self-select out of the bidding process early, not after you have invested weeks in evaluation.
Site visit logistics in the RFP process
Construction RFPs should include a mandatory or strongly recommended site visit. Bidders who have not seen the site will make assumptions. Some of those assumptions will be wrong, and you will pay for the difference.
In the RFP, specify:
- Site visit date and time (one session minimizes advantage to early arrivals)
- Whether questions from the site visit will be answered in a formal addendum
- Photo documentation policy (most owners allow it)
- Contact for site access coordination
A mandatory site visit also reduces the likelihood of bids based on the drawings alone from contractors who have not verified site conditions.
How to evaluate construction bids beyond lowest price
Lowest price does not mean lowest cost. A contractor who prices low and performs poorly will cost more than a contractor who bid higher and delivered on schedule.
Structure your evaluation across these dimensions:
Price: Total bid amount, including allowances and unit prices. Normalize bids to account for scope interpretation differences before comparing.
Schedule: Does the proposed schedule match your requirements? Are the milestone dates realistic given the scope?
Relevant experience: Projects of similar type, scale, and complexity, completed in the past five years. References who can speak to the quality and reliability of execution.
Team qualifications: The superintendent assigned to your project matters as much as the company's overall reputation. Ask who will actually be on site.
Financial stability: For large projects, request financial statements or a bank reference. A contractor who cannot finance the early phases of a project will ask you to accelerate payment or will slow the work.
Safety record: Per the EMR and OSHA documentation described above.
Weight these criteria explicitly in your RFP, and score them before price is revealed if your process allows it. This reduces the anchoring effect that lowest price creates when evaluators see cost first.
What to leave out of a construction RFP
Generic questions that do not help you evaluate: "Describe your project management philosophy." "What makes you different from other contractors?" These produce boilerplate answers you cannot score.
Overly prescriptive means specifications when performance specifications are appropriate. If you specify every detail of how the work is to be done, you own the method. If the method fails, the contractor has a change order argument.
Page limits that are so tight bidders cannot provide the documentation you actually need. If you want OSHA logs, safety programs, and subcontractor lists, give bidders enough space to include them.
A well-structured construction RFP takes more time to write than a template fill-in. It saves that time many times over during the project.
