In many construction projects, an RFQ for contractors is issued with what appears to be a clear scope, yet the owner is surprised by major price differences between bids.

In most cases, the issue is not contractor capability — it is unclear requirements or missing information that allows each bidder to interpret the scope differently.

A professional construction RFQ does not simply request a price.
It standardizes the pricing approach so comparisons become fair, transparent, and technically meaningful.

1. Define the Scope of Work Clearly and Precisely

The first requirement in any RFQ for construction projects is a scope that cannot be easily misinterpreted.

This should include:

• Clear boundaries of work (what is included and excluded)
• Reference drawings and specifications
• Estimated quantities or BOQ documents where available

Most importantly, the RFQ should require contractors to confirm their understanding of the scope and clearly state any assumptions used in pricing.

Expected Outcome

Reducing hidden assumptions that later create unexpected price gaps or disputes.

2. Ask Direct Questions About Technical Assumptions

Instead of allowing contractors to build pricing around undeclared assumptions, the RFQ should ask targeted technical questions such as:

• What site levels or soil conditions were assumed?
• Does the pricing include night work or work within an operating facility?
• What quality standards or testing requirements are included?

These questions force bidders to reveal the basis of pricing, making technical comparison easier — not just numerical comparison.

3. Standardize the Pricing Structure

One major reason bids vary significantly is because contractors allocate costs differently.

A professional RFQ should therefore include a standardized pricing template requesting:

• Detailed pricing for major work sections
• Separation of material and labor costs where necessary
• Clear identification of overheads and profit margins

When financial formatting is standardized, the real pricing differences become visible instead of hidden within lump-sum values.

4. Request Schedule and Resource Information

Price should never be evaluated independently from project duration.

The RFQ should require contractors to provide:

• Proposed execution duration
• Planned manpower and equipment resources
• Procurement plans for critical materials

A contractor with a lower price but a much longer schedule may ultimately cost the project far more through delays.

5. Address Risks and Variation Procedures Early

A professional RFQ should explicitly ask contractors to identify:

• High-risk items within the scope
• Excluded works
• Pricing methodology for future variation orders

This level of transparency reduces future disputes and reveals the true differences between proposals.

6. Clarify Quality and Approval Requirements

To avoid price differences caused by inconsistent quality expectations, the RFQ should clearly define:

• Applicable standards and specifications
• Testing requirements
• Required supervision and inspection levels

Without these details, some contractors may price based on minimum acceptable quality while others price according to higher standards — creating misleading cost gaps.

Frequently Asked Questions About Construction RFQs

What is the difference between an RFQ and an RFP in construction?

An RFQ focuses primarily on obtaining pricing for a defined scope, while an RFP evaluates broader technical approaches, methodologies, and proposed solutions.

Why do contractor prices vary so much for the same project?

Because contractors may use different assumptions, pricing methods, or interpretations of the scope.

Is sending drawings alone enough for a quotation request?

No. The scope boundaries and pricing assumptions should also be clarified to minimize inconsistencies between bids.

How can bids be compared fairly?

By using a standardized pricing format and requesting detailed information about schedule, resources, and risks.

What is the most important factor in reducing disputes after award?

Transparency in assumptions and early documentation of exclusions within the submitted quotation.
