In construction dispute resolution, the most common observation I make is this: the dispute was avoidable. Not always — construction projects are complex, multi-party undertakings with inherent risk. But a significant proportion of the instructions I receive arise from contractual and commercial practices that, with better advice earlier, would never have reached formal proceedings.
For legal teams and solicitors advising clients at the outset of a project — or during early-stage disagreements — understanding the upstream causes of construction disputes offers a practical framework for both prevention and, where disputes do arise, stronger case preparation.
1. Treat the Contract as a Live Document
The single most consistent root cause of construction disputes is a contract that was signed and filed. In practice, many construction contracts — particularly on SME projects — are executed without either party reading them carefully, and then referenced only when something goes wrong.
The JCT, NEC and FIDIC suites each impose specific procedural obligations: notice periods, early warning requirements, time bars for claims. Missing these steps doesn’t just affect quantum — it can extinguish entitlement entirely. Clients who understand their contract as a living operational document, not a legal formality, are substantially better protected.
For legal advisers, this means encouraging clients to review key contract mechanisms at project outset: variation procedures, extension of time provisions, payment terms, and dispute notice requirements. An hour spent at this stage is worth considerably more than the same hour spent reconstructing events two years later.
2. Contemporaneous Records Are Not Optional
Construction disputes are, at their core, disputes about facts. What was instructed, when, by whom, and what effect it had on cost and programme. When those facts are contested — and they usually are — the party with better records almost always has the stronger position.
The problem is that construction teams are focused on building things, not creating audit trails. Site diaries are inconsistent, variations are agreed verbally, emails go unanswered. By the time a dispute crystallises, the evidential picture is fragmentary.
Advising clients to maintain contemporaneous records — site diaries, dated photographs, written confirmation of verbal instructions, regular programme updates — is not a counsel of perfection. It is the baseline for any viable claim or defence. From a quantum perspective, reconstructing cost and delay entitlement from incomplete records is significantly more expensive and less reliable than working with good contemporaneous evidence.
3. Deal With Disagreements While the Project Is Live
There is a natural reluctance on construction projects to escalate disagreements while work is ongoing. Clients worry about disrupting relationships, contractors are concerned about retention, and no one wants to be seen as the party that “went legal.” The result is that disputes are deferred, positions harden, and the factual record becomes stale.
The notice and early warning provisions in most standard form contracts exist precisely to counter this tendency. They are designed to bring issues to the surface while they can still be managed commercially, before entitlements are lost and positions become entrenched.
In practice, encouraging clients to raise issues promptly — in writing, using the correct contractual mechanism — both preserves their legal position and creates opportunities for commercial resolution before formal proceedings become necessary. It also generates the contemporaneous record discussed above.
4. Instruct a Quantity Surveyor Early in a Dispute
When a construction dispute reaches a solicitor’s desk, it frequently arrives without a clear quantum narrative. The client knows they have lost money and believes the other party is responsible. Translating that into a technically coherent claim — one that survives scrutiny in adjudication, mediation or litigation — requires a construction professional with both contractual knowledge and quantity surveying expertise.
Early instruction of a specialist quantity surveyor allows the claim to be properly scoped and valued before proceedings are commenced, avoiding the risk of overstating or understating entitlement. It also identifies evidential gaps while there is still an opportunity to address them, and enables a realistic assessment of prospects that informs settlement strategy.
Legal teams who involve construction experts at an early stage — rather than once pleadings are in draft — consistently achieve better outcomes for their clients.
5. Know Which Dispute Resolution Route Fits the Instruction
Not every construction dispute should go to adjudication, and not every dispute is suitable for mediation at the outset. The appropriate route depends on the nature of the dispute, the parties’ commercial objectives, the strength of the available evidence, and the likely timeline.
Adjudication is fast and relatively cost-efficient, but the 28-day timetable places significant demands on preparation. Mediation is more flexible and preserves relationships, but requires the parties to be ready to negotiate — which may not be the case where entitlement is genuinely disputed. Arbitration and litigation offer finality and full evidential disclosure, but at substantially greater cost and over a longer timeframe.
A clear-eyed assessment of which route is most likely to achieve the client’s objectives — and the costs and risks of each — is among the most valuable input a construction dispute specialist can provide. It is also the conversation that should happen before proceedings are issued, not after.
