RFPs, RFQs & RFIs. Pick the right instrument — get the right bid.
RFPs, RFQs and RFIs are the three construction procurement requests. An RFP compares how vendors will solve a complex scope, an RFQ compares price on a well-defined scope, and an RFI gathers market intelligence before formal solicitation. If you have a firm, fully specified scope, send an RFQ; if you do not, send an RFP.
Three instruments.Three distinct purposes.
Choosing the right procurement request determines the quality and relevance of responses you receive. Use the wrong one and you get either unresponsive bids or no bids at all.
Should you send an RFP or an RFQ?
Reach for an RFP when the scope is complex or still taking shape and you need vendors to propose an approach, a team, and a methodology alongside price — design-build, CM/GC selection, or a specialty subcontractor. Reach for an RFQ when the scope is already well defined and you mainly need competitive pricing on known quantities or materials. Put simply, an RFP compares how vendors will solve the problem, while an RFQ compares how much for a fixed scope. If you are unsure, ask whether you have a firm, fully specified scope yet: if you do, send an RFQ; if you do not, send an RFP.
| Attribute | RFP — Request for Proposal | RFQ — Request for Quote | RFI — Request for Information |
|---|---|---|---|
| Purpose | Solicit detailed proposals including approach, methodology, and pricing for complex scopes | Obtain competitive pricing for well-defined materials, quantities, or simple scopes | Gather market intelligence, capabilities, and preliminary information before formal solicitation |
| When to Use | Complex services, design-build, CM/GC selection, specialty subcontractor procurement | Material procurement, commodity purchases, trades with clear specs and quantities | Pre-procurement research, market sounding, identifying potential vendors and solutions |
| Response Time | 2–6 weeks | 3–10 business days | 1–3 weeks |
| Level of Detail | High — scope, approach, team qualifications, schedule, pricing breakdown | Medium — unit pricing, delivery terms, lead times, payment terms | Low — capabilities overview, past projects, general pricing ranges |
| Best For | Complex services & scopes | Materials & simple scope | Information gathering |
| Evaluation | Multi-criteria weighted scoring (qualitative + quantitative) | Primarily price-based with delivery and terms comparison | Qualitative review; no binding commitment |
| Binding? | Proposals typically binding for stated validity period | Quotes binding per stated terms (often 30–60 days) | Not binding — informational only |
What goes into a construction RFP?
A construction RFP has eight sections: project overview, scope of work, technical specifications, timeline and milestones, budget range, evaluation criteria, submission requirements, and terms and conditions. A well-structured RFP ensures you get comparable, complete proposals. Every section serves a purpose — skip one and you invite scope gaps, inflated pricing, or non-responsive bids.
What goes into a material RFQ?
A construction material RFQ has six sections: material specifications, quantities, delivery requirements, Incoterms and freight, insurance requirements, and payment terms. RFQs are simpler than RFPs — the scope is defined, and you need competitive pricing to check against your own cost estimate. Here are the essential sections for a construction material RFQ.

Reach them through your existing vendor database, industry directories, trade associations, online bid platforms, and referrals and networking. The best-written RFP is worthless if it doesn't reach qualified bidders. Use multiple channels to maximize competitive tension and response quality.
Existing Vendor Database
Your prequalified vendor list is the first stop. These are firms you have vetted, worked with, or pre-approved. They produce the most reliable responses because they already understand your standards and expectations.
Industry Directories
Blue Book, Dodge Data, ABC member directories, and local AGC chapter rosters. These sources help you identify specialty contractors and suppliers outside your immediate network, especially for niche scopes.
Trade Associations
Reach trade-specific organizations: SMACNA for sheet metal, NECA for electrical, MCA for mechanical. Many associations offer bid boards or member distribution services that reach qualified specialty firms.
Online Bid Platforms
Bid exchange platforms (iSqFt, BuildingConnected, PlanHub) give you access to thousands of subcontractors and suppliers. Effective for casting a wide net, especially on public or large commercial projects.
Referrals & Networking
Ask project owners, architects, and trusted trade partners for referrals. Word-of-mouth recommendations often surface the best-fit contractors — firms that won't respond to cold solicitations but will bid when referred.
Weighted scoringturns opinions into defensible decisions.
Define criteria and weights before opening any proposals — then score consistently. The highest total represents the best-value proposal, not necessarily the lowest price — provided you score leveled bid totals rather than raw headline numbers. Run each bid through Bid Scope Compliance first to flag missing items, exclusions, and substitutions against the spec, so a scoring gap doesn't turn out to be a scope gap in disguise.
| Criteria | Weight | Description | Bidder ARaw (1–10) | Bidder AWeighted | Bidder BRaw (1–10) | Bidder BWeighted |
|---|---|---|---|---|---|---|
| Price | 30% | Total bid price, unit rates, cost completeness, and reasonableness | 8 | 2.40 | 9 | 2.70 |
| Technical Capability | 25% | Approach, methodology, understanding of scope, innovation, and technical resources | 9 | 2.25 | 7 | 1.75 |
| Schedule | 15% | Proposed timeline, milestones feasibility, and resource loading | 7 | 1.05 | 8 | 1.20 |
| Experience | 15% | Similar project history, team qualifications, and relevant certifications | 8 | 1.20 | 6 | 0.90 |
| Safety | 10% | EMR, OSHA recordable rates, safety program, and incident history | 9 | 0.90 | 8 | 0.80 |
| References | 5% | Client references, repeat client ratio, and reference feedback quality | 7 | 0.35 | 7 | 0.35 |
| Total | 100% | 8.15 | 7.70 |
How to calculate: Multiply raw score by weight percentage. Example: Bidder A scores 8 on Price (30% weight) = 8 × 0.30 = 2.40 weighted points.
Sum all weighted scores for the total. The highest total represents the best-value proposal — not necessarily the lowest price.
Which mistakes inflate your next bid?
Six mistakes inflate bids or reduce proposal quality: a vague scope of work, too short a response time, missing evaluation criteria, no mandatory site visit, overly restrictive specs, and no pre-bid Q&A process. Each of these mistakes directly increases your project cost or reduces the quality of proposals you receive. Recognize them before they end up in your next solicitation.
Vague Scope of Work
When bidders can't clearly define what's included, they add contingency to protect themselves. A vague scope inflates bids across the board. Trueleveler's Scope Builder turns your spec text into trade-by-trade inclusions and exclusions before you issue the RFQ, so bidders price the same scope instead of guessing.
Result · Inflated bids & scope disputesToo Short Response Time
Compressing the response window eliminates bidders who need time to coordinate with sub-tier suppliers and develop thoughtful proposals. You end up with fewer bids and less competition.
Result · Limited competition & rushed proposalsMissing Evaluation Criteria
Without published criteria and weights, evaluators fall back on gut feelings and internal biases. This creates protest risk on public jobs and inconsistent decisions on private ones.
Result · Subjective & indefensible decisionsNo Mandatory Site Visit
Bidders who haven't seen the site can't account for access constraints, staging limitations, existing conditions, or logistical challenges. Expect change orders and claims after award.
Result · Inaccurate pricing & change ordersOverly Restrictive Specs
Specifying a single manufacturer without “or equal” language eliminates competitive pricing. If only one vendor can bid, you've created a sole-source situation with no price tension.
Result · Sole-source pricing & no leverageNo Pre-Bid Q&A Process
Without a formal RFI period, bidders make assumptions that diverge. One bidder includes an item, another excludes it. Proposals become impossible to compare on an apples-to-apples basis — the gap bid leveling is designed to close.
Result · Non-comparable proposalsPublic procurementadds compliance layers.
Missing any of these requirements can disqualify a bid or expose the awarding agency to legal challenge. If you're bidding or issuing public work, these are table stakes.
Sealed Bid Requirements
Public agencies typically require sealed bids opened at a specific date, time, and location. Late submissions are rejected regardless of content. Many jurisdictions now accept electronic sealed bids through certified platforms.
Prevailing Wage & Davis-Bacon
Federally funded projects require Davis-Bacon Act compliance with prevailing wage rates. State-funded projects may have their own prevailing wage laws. Bidders must certify compliance and maintain certified payroll records.
M/DBE & Small Business Goals
Most public projects set Minority/Disadvantaged Business Enterprise (M/DBE) participation goals, typically 10–30%. Bidders must demonstrate good faith efforts to meet these targets, even if goals are aspirational rather than mandatory.
Lowest Responsible Bidder
Public agencies must generally award to the “lowest responsible bidder” — not just the lowest price. “Responsible” means the bidder has the capacity, resources, and track record to perform. Agencies can reject unreasonably low bids.
Bid Bonds & Performance Bonds
Public projects typically require a 5–10% bid bond guaranteeing the bidder will enter into a contract if selected. After award, 100% performance and payment bonds are standard on projects above threshold amounts.
Protest & Appeal Procedures
Unsuccessful bidders on public projects can formally protest award decisions. Agencies must document their evaluation process, maintain records, and follow established protest resolution procedures to withstand legal challenge.
What happens from award to contract?
Four steps lead from award to contract: award notification, a pre-award meeting, contract negotiation, and the Notice to Proceed. Selecting a bidder is only half the process. The path from award notification to Notice to Proceed involves critical steps that set the tone for the entire project.
Award Notification
Notify the selected bidder in writing. Simultaneously notify unsuccessful bidders and offer debriefs. Include any conditions of award and required response timeline.
Pre-Award Meeting
Review scope, clarify assumptions, align on key personnel, discuss schedule constraints, and confirm pricing. Resolve any outstanding questions before contract execution.
Contract Negotiation
Finalize contract terms: insurance certificates, bonds, retainage, change order procedures, and dispute resolution. Ensure all proposal representations are incorporated into the agreement.
Notice to Proceed
Issue the formal NTP with the contract start date. This triggers mobilization, submittals, scheduling, and procurement activities. The project clock starts here.
