Requests for Proposals (RFPs) are a core document for construction procurement in Australia. When done correctly, they align expectations, establish clear evaluation criteria, and create accountability between owners and contractors.

However, poorly structured RFPs create significant business risks, introducing ambiguity into scope definitions, attracting unqualified contractors, and leading to potential disputes and budget overruns. The difference between a properly executed and problematic RFP often comes down to structure, clarity, and strategic distribution.

This guide breaks down what to include in an RFP, how the process works, and how to avoid common issues faced by both project owners and contractors.

What is an RFP in Construction?

A RFP is a formal procurement document used to source qualified contractors for a specific construction project. Issued by the project owner, it invites detailed proposals that outline how each contractor would approach delivery. 

RFPs are common in both public and private sector projects across Australia and are used in many contract types including design-bid-build and design-build delivery models. In multi-stage procurement processes, they are often preceded by a request for qualifications (RFQ).

RFPs play an important role in construction procurement. They provide a structured, accountable way to evaluate capabilities, compare methodologies, and assess costs before awarding contracts. 

By standardising the scope, technical requirements, timeline, and budget expectations, RFPs ensure all bidders are working from the same baseline. 

What to Include in an RFP?

Project Description

Provide a high-level overview of the project and who is issuing the RFP. Include:

• The purpose of the work and the outcomes the project is expected to achieve
• Relevant background about the project, site, or organisation
• Key dates such as submission deadlines, project launch targets, or approval timelines
• Contact details for clarification, including a designated point of contact for queries

Scope of Work

Clarify exactly what the contractor will be responsible for. Detail:

• The main tasks and deliverables expected under the contract
• Technical specifications such as plans, materials, design criteria, or workmanship standards
• Site-specific conditions that could affect delivery, such as access constraints, staging limitations, or weather risks
• What is and isn’t included in the contractor’s scope, to prevent misguided assumptions

Project Schedule

Set clear expectations for timing and sequencing. Specify:

• The target commencement and completion dates
• Any major milestones or staged handover points
• Critical deadlines or time-sensitive components that could affect sequencing or coordination

Submission Guidelines

Make it easy for contractors to respond correctly and completely. Outline:

• The preferred proposal structure and formatting requirements
• How submissions should be delivered (e.g., online portal, email, or hard copy)
• File type preferences, naming conventions, or number of copies required
• Mandatory attachments or declarations that must be included with the submission

Evaluation Criteria

Give contractors a clear understanding of how their proposal will be judged. Define:

• The specific criteria being assessed, such as relevant experience, delivery methodology, team capability, pricing, or timeline
• Any weightings, minimum thresholds, or non-negotiable requirements
• Whether interviews, presentations, or clarifications may be part of the evaluation process

Contract Terms and Conditions

Help bidders assess commercial fit before they commit resources to a response. Provide:

• A draft contract or a clear summary of proposed terms
• Key commercial terms, including payment schedule, retention clauses, and insurance levels
• Information about dispute resolution processes and escalation pathways
• Details on warranties, liabilities, and performance requirements
• An open channel for bidders to raise questions or flag potential issues during the tender period

The Construction RFP Process

While every project differs in complexity, most construction RFPs follow a structured process that supports transparency and accountability. Understanding each stage helps both owners and contractors navigate procurement more effectively, reducing misalignment and improving project outcomes from the outset.

The Owner Defines Project Details

The owner confirms the scope, objectives, and constraints, selects the delivery method (design-bid-build or design-build), and sets the key parameters: budget, timeline, and performance requirements.

The Owner Writes and Issues the RFP

Next, the RFP is drafted to reflect the delivery model and complexity of the work. 

It outlines the scope of work, technical requirements, submission guidelines, evaluation criteria, and proposed contract terms, providing a complete and accurate picture for potential bidders.

The Owner Publishes and Distributes the RFP

In private projects, the RFP is sent to a shortlist of prequalified contractors. In the public sector, it’s published through open tender portals or government procurement platforms (like ) to meet compliance requirements.

Contractors Prepare Their Proposals

Contractors review the RFP and prepare a tailored response covering scope, methodology, pricing, and risks. This typically involves site visits, cost estimation, and coordination with consultants and subcontractors.

Contractors Submit Proposals

Submissions must meet all formatting and deadline requirements. Non-compliant or late bids are usually disqualified, so accuracy and completeness are critical.

The Owner Evaluates the Proposals and Selects a Contractor

Owners assess submissions against the evaluation criteria, which may include shortlisting, scoring, interviews, or clarification rounds. The chosen contractor offers the best combination of capability, methodology, pricing, and value.

The Owner and Contractor Negotiate the Contract

The parties finalise scope, pricing, milestones, and commercial terms. Once agreed, the contract is signed and formally awarded.

Challenges with RFPs and How to Solve Them

Time-Intensive Process

Preparing and responding to RFPs requires significant coordination. Contractors often rely on input from estimators, engineers, and commercial teams to build a compliant submission. On the owner's side, approvals can stall if responsibilities aren’t clearly defined.

Build speed and consistency by:

• Developing standardised templates
• Setting up pre-approved content libraries
• Assigning clear ownership for each task in the RFP workflow
• Using shared calendars and digital tools to coordinate inputs across teams

Ambiguity in RFP Documents

Vague scope or missing details can result in inconsistent bids, excessive RFIs, or pricing gaps. Misalignment at this stage increases the chance of change orders or disputes once the project begins.

Improve accuracy by using a standard checklist to validate key content across scope, specs, timelines, and site conditions. Have an experienced contractor or consultant review the RFP before publishing to spot gaps that owners might miss internally.

Complexity of the Process

Each stage of the RFP lifecycle brings new stakeholders and risks. Without a clear framework, critical steps can be rushed or skipped.

Resource and Fit Challenges for Contractors

Contractors need to determine if an opportunity fits their pipeline, risk appetite, and delivery capacity. Submitting on poor-fit tenders leads to lost time, lower margins, and underperformance if awarded.

Contractors can sharpen bid discipline by applying a go/no-go framework that assesses project fit based on resource availability, risk profile, margin thresholds, and strategic alignment. Regularly review win-loss data to refine criteria.

Unworkable Proposals

Unclear or unrealistic expectations lead to proposals that overlook key constraints, causing problems later during delivery.

Improve proposal quality by holding early market engagement sessions or issuing a draft RFP for feedback. Use the insights gathered to adjust delivery timeframes, clarify scope boundaries, and confirm commercial viability before final release.

Difficulties in Evaluating Proposals

Without clear, structured evaluation criteria, reviews become inconsistent and subjective, putting contract awards at risk.

Contract Risks

Tenderers often encounter amended contract terms that increase their risk exposure. Without early visibility, contractors may submit pricing that does not account for key liabilities.

Ensure transparency by including a summary of key contract terms in the RFP. Clearly flag non-negotiables, outline retention and insurance requirements, and offer a structured Q&A period so contractors can raise concerns early.

Limited Competition

If the RFP is poorly structured or not widely distributed, it may fail to attract quality submissions. A limited pool reduces the ability to compare value or negotiate improvements.

Boost competition by distributing RFPs via reputable industry platforms, maintaining a vetted prequalification list, and keeping the documentation clear, accessible, and well-structured. Provide enough lead time for quality submissions.

A clear and complete construction RFP improves cost control, contractor selection, and project outcomes.

Well-structured RFPs help owners compare proposals on equal terms, reduce early-stage risk, and set clear delivery expectations. The result is stronger alignment, fewer disputes, and better project performance from day one.
