In the world of construction, bidding isn’t just paperwork—it’s strategy, survival, and success. Whether you’re building duplexes in Sydney or townhouses in Brisbane, mastering the construction bidding process is essential for delivering profitable, well-managed projects.
At OwnerDeveloper, we’ve worked with developers, builders, and contractors across Australia to deliver residential projects that don’t just break ground—but break industry benchmarks. Today, we’re lifting the lid on the construction bidding process: what it really looks like, where people get it wrong, and how to do it right.
🔁 The 5 Key Stages of a Construction Bid
Bid Solicitation
This is where it all begins. The project owner (or developer) sends out an Invitation to Tender—often via RFQ, RFP, or IFB. These documents outline the project’s specs, budget, scope, and expectations.
📌 Top Tip: For developers, this is your chance to prequalify contractors. Review their safety records, licenses, relevant experience, and financial stability before you even receive a price.
Bid Submission
Contractors prepare detailed bids covering material takeoffs, labour estimates, subcontractor pricing, and overheads. Many submit a bid bond—a security measure to ensure they can deliver what they’ve promised.
📌 Top Tip: A clear, concise, well-documented bid speaks volumes. At OwnerDeveloper, we often advise homeowners and JV partners to look beyond the price—reviewing bid structure, timelines, and team credentials.
Bid Selection
It’s not always the lowest price that wins—it’s the best value. Developers often weigh price, timeline, relevant experience, and methodology. The selection process may include bid leveling—a structured comparison of proposals to ensure “apples-to-apples” evaluation.
📌 Top Tip: Track all your bids—even the ones you don’t win. Analysing losses is just as valuable as celebrating wins.
Contract Formation
Once a bid is accepted, the contract is drafted and negotiated. This includes delivery methods (Design-Bid-Build, Design-Build, etc.), payment schedules, performance clauses, and risk allocation.
📌 Top Tip: Never sign a boilerplate contract without reviewing it in detail. We’ve seen even seasoned builders overlook clauses that later caused legal and financial headaches.
Project Delivery
Although technically post-bid, the agreed project delivery method influences the entire process. Whether it’s lump-sum, GMP, or cost-plus, the chosen model shapes risk-sharing and accountability.
📌 Top Tip: Align your project delivery method with your development goals—fast turnaround? Consider Design-Build. Cost certainty? Explore fixed-price or GMP models.
📊 Types of Construction Tenders: Which Is Right for You?
Understanding tender types can drastically impact project risk, transparency, and cost control:
Open Tendering – Competitive, public, ideal for government work.
Selective Tendering – Invite-only. Balances quality with efficiency.
Negotiated Tendering – One-on-one. Best for specialist or ongoing work.
Serial Tendering – For repeated projects, e.g., developers rolling out 10+ townhouses over 2 years.
💡 At OwnerDeveloper, we often use selective and negotiated tenders with our internal teams and vetted builder partners to maintain control, quality, and speed.
💥 The Hidden Risks of Rushed Bids
Many first-time developers or homeowner-builders fall into the trap of accepting the cheapest bid—or rushing their own submissions without accurate site assessments, documentation, or cost breakdowns.
Some common pitfalls we’ve seen include:
Underestimating escalation in material costs.
Missing hidden site constraints due to no pre-bid site visit.
Submitting incomplete documentation that gets bids disqualified.
✅ The fix? Preparation, systems, and strategy. We often work with developers to guide them through every stage—from tender prep to contractor onboarding—to reduce risk and improve outcomes.
🧠 Final Word: Bidding Is Both Science and Strategy
Bidding isn’t just about submitting numbers. It’s about presenting a case for why your team, method, and approach offer the most value—not just the lowest cost. The developers who win projects (and profit from them) understand this.
At OwnerDeveloper, we assist our clients through the full lifecycle—from feasibility to handover—and that starts with smart, data-driven bidding.
