The best way to avoid construction disputes isn’t to manage claims better—it’s to create fewer claims in the first place.
Introduction
By the time a project becomes consumed by variation claims, extension of time requests and contractual disputes, the underlying problem has usually existed for months.
The claim itself is rarely the cause of the dispute.
Across Queensland, we continue to see projects where significant time and money is spent administering claims that could largely have been avoided through better project definition, more thoughtful contract drafting and stronger contract administration.
As infrastructure programs accelerate towards 2032, councils are understandably focused on delivering projects quickly. However, as we have observed before, in compressing procurement and design timeframes, there is a growing risk that projects proceed to market before the scope, documentation and allocation of responsibilities have been properly settled.
The consequence is more variations, more claims and more disputes.
Variations Are Usually a Symptom, Not the Problem
Variations are an inevitable feature of construction projects. Site conditions change, stakeholder requirements evolve and unforeseen issues arise.
The problem is not that variations occur. The problem is when projects are structured in a way that almost guarantees them.
In our experience, recurring causes include:
- incomplete or evolving design documentation;
- poorly defined scopes of work;
- unrealistic project budgets or programs;
- inconsistent tender documentation;
- assumptions that are not clearly documented; and
- responsibilities that are implied rather than expressly allocated.
Each uncertainty creates an opportunity for disagreement later.
Once construction has commenced, resolving those uncertainties becomes considerably more expensive.
The Cost of Poor Scope Definition
The single greatest contributor to avoidable claims is an unclear scope of work.
Where documents leave room for interpretation, contractors must price uncertainty. If that uncertainty later materialises, it frequently becomes the subject of a variation or contractual claim.
Examples include:
- incomplete specifications;
- conflicting drawings;
- undefined interfaces between contractors;
- provisional design information; and
- assumptions regarding existing services or site conditions.
Every unresolved issue at procurement stage becomes a commercial issue during delivery.
Investing additional effort before tender is almost always significantly cheaper than attempting to resolve disputes after construction begins.
Procurement Decisions Shape Contract Outcomes
Many variation disputes originate before a contract is even signed.
Compressed procurement programs can lead to:
- incomplete project documentation;
- insufficient market engagement;
- unrealistic pricing expectations;
- inadequate risk assessment; and
- contract amendments prepared without fully considering their practical consequences.
Under delivery pressure, there is often a temptation to “get the project to market” and resolve outstanding issues later. Unfortunately, “later” usually becomes a variation claim.
Procurement is therefore not simply about selecting a contractor. It is about establishing the commercial framework within which the project will be delivered.
Risk Allocation Still Matters
Article 4 of this series discussed the growing shift away from simply transferring risk to contractors. Article 5 builds on that theme.
Even where risk allocation is generally appropriate, uncertainty about who carries a particular risk frequently becomes fertile ground for disputes.
Examples include:
- latent site conditions;
- utility relocations;
- third-party approvals;
- authority requirements;
- existing asset information; and
- design development responsibilities.
A well-drafted contract does not eliminate risk. It clearly allocates responsibility for managing that risk before issues arise.
Contract Administration Can Prevent Escalation
Even well-prepared contracts require disciplined administration.
Some of the most common issues we observe include:
- delayed responses to contractor notices;
- inadequate assessment of variation requests;
- inconsistent superintendent decisions;
- poor project record keeping;
- verbal instructions not formally documented; and
- uncertainty regarding delegated authority.
Small administrative issues often compound over time. By the time formal claims emerge, positions have become entrenched and commercial relationships have deteriorated.
Effective contract administration is therefore not merely a compliance exercise. It is a risk management function.
Five Practical Ways to Reduce Claims
Councils can significantly reduce variation and claim exposure by focusing on five practical areas.
1. Invest More Time Before Tender – Ensure the scope is sufficiently developed before approaching the market. Additional planning time often reduces months of dispute later.
2. Clearly Allocate Risk – Avoid assumptions. If responsibility for an issue is important, expressly identify who bears the risk and under what circumstances.
3. Select the Right Contract Model – Different projects require different delivery models. A contract that works well for straightforward construction may not suit complex infrastructure involving design development, staging or operational interfaces.
4. Maintain Disciplined Contract Administration – Respond to notices promptly. Document decisions. Maintain complete project records. Consistency throughout the project significantly improves outcomes if disagreements later arise.
5. Focus on Collaboration Before Positions Harden – Many claims can be resolved through early commercial discussions before parties become committed to contractual positions. Early engagement often preserves both relationships and project momentum.
What This Means for Councils
As infrastructure delivery accelerates over the coming decade, contract certainty will become increasingly valuable. Councils should view contracts not simply as legal documents, but as delivery tools.
Well-prepared contracts:
- reduce uncertainty;
- encourage competitive pricing;
- improve project relationships;
- minimise claims; and
- support successful delivery outcomes.
Conversely, poorly prepared contracts transfer uncertainty into the construction phase—where resolving it is invariably more costly.
Conclusion
Claims management should never be the primary strategy for delivering successful infrastructure. The better strategy is to reduce the circumstances in which claims arise. That requires investment before procurement, disciplined contract drafting, appropriate risk allocation and consistent contract administration.
In today’s constrained infrastructure market, certainty has become one of the most valuable project outcomes a council can achieve.
Projects with greater certainty attract stronger market interest, achieve better pricing and are significantly more likely to be delivered on time and within budget.
