Delays remain one of the most frequent causes of disagreement in construction projects. They drive up costs, disrupt programmes, strain commercial relationships, and can ultimately lead to formal disputes. While every project has its own complexities, delay-related conflicts tend to arise from a small number of recurring issues. Understanding these early can significantly reduce risk and avoid costly escalation.
1. Poor Contract Management
A large proportion of disputes stem from poorly drafted, unclear, or misunderstood contract provisions. Ambiguity around completion dates, requirements for notifying delays, or entitlement to extensions of time often becomes a problem only once delays occur.
Under both JCT and NEC contracts, failing to provide timely notice of a delay can result in losing the right to claim additional time or money — even where the delay is legitimate. This is one of the most common and avoidable causes of conflict.
How to mitigate this:
Before works begin, ensure the entire project team understands the contract’s procedures for notifying delays, assessing extensions of time, and updating the programme. All time-related provisions should be reviewed carefully and written clearly to avoid uncertainty later.
2. Poor Communication and Weak Record Keeping
Even with a well-constructed contract, breakdowns in communication and inadequate record keeping can undermine any claim or defence. Missing site records, inconsistent progress updates, or undocumented discussions make it difficult to establish what truly caused a delay.
When a dispute reaches adjudication, arbitration, or litigation, the absence of reliable evidence can weaken an otherwise strong position.
How to prevent it:
Maintain accurate daily site records, confirm key conversations in writing, and keep progress reports and programmes up to date. Good documentation not only helps resolve issues quickly on site but can also avoid formal disputes entirely.
3. Ineffective Management of Change Events
Design changes, variations, and late instructions are common on construction projects — but when they are not managed properly, the impact on the programme can be significant. Disagreements frequently arise when parties cannot agree on the time consequences of changes, particularly if their effect is assessed too late.
How to prevent it:
Put in place a clear procedure for managing variations at the pre-contract stage. Assess the time impact of each change as soon as it arises, update the programme regularly, and communicate any adjustment to completion dates promptly. A current and accurate programme is essential for reducing the risk of dispute.
Most delay disputes originate from ambiguous contracts, poor communication, or ineffective change control. Taking time at the outset to clarify obligations, establish good record-keeping practices, and manage variations consistently will significantly reduce the likelihood of disputes arising later.
