Construction projects disagree constantly and almost none of it becomes a dispute. A valuation is cut, somebody rings up, the next certificate puts it back. That is the system working. The difficulty is that the process which produces a real dispute looks identical at the start, and by the time the difference is obvious the cheap options have gone. An initial dispute review exists for that gap.
The practical question is not philosophical. It is whether you are still in a conversation that will resolve itself through the contract machinery, or whether you have crossed into something that needs to be built, evidenced and argued. The two situations call for different behaviour, and continuing to behave as though you are in the first when you are in the second is how positions get lost.
The crossing point is rarely dramatic
In most cases there is no single event. There is a sequence: a figure is refused, the refusal is repeated, a reason is given that does not match the contract, and somebody writes a letter that is a little firmer than the last one. Each step is reasonable on its own. Taken together they are the opening of a case.
What marks the change is usually that one side stops engaging with the merits and starts restating a position. Questions go unanswered. Figures stop being explained. The exchange becomes about who said what rather than about what the contract provides. At that point the commercial conversation has ended, whatever the tone of the emails suggests.
The second marker is internal. When your own team starts keeping records specifically because of this issue, rather than because the project requires it, they have already concluded that it is heading somewhere. That instinct is usually right and it is worth acting on rather than waiting for confirmation.
What changes once it is a dispute
The first change is that correspondence stops being administration and becomes evidence. Everything written from that point will be read later by somebody looking for inconsistency. Loose language that would have passed unnoticed in a working relationship becomes material.
The second is that the contract starts to matter in a way it did not before. Provisions that were ignored while things were going well, particularly notice requirements and time limits, become the frame within which the argument has to fit. A good commercial point that was not notified in the way the contract required can be worth very little.
The third is cost. A dispute consumes senior time, and senior time is the most expensive thing on any project. That cost is incurred whether or not the claim succeeds, which is why the decision to run one deserves the same scrutiny as any other commercial commitment.
The questions that settle it either way
Three questions decide most of it. Does the contract give a right to additional payment or time for what actually happened. Was whatever the contract required by way of notice done, and done in time. Do the records show what you say they show, in a form somebody else can follow.
Those questions can be answered quickly, and they are much cheaper to answer early. Answering them late, after a position has been stated in writing several times, means discovering the weakness at the point where retreating is embarrassing as well as expensive.
The answers also determine the sensible route. A strong entitlement with poor records is a different problem from a weak entitlement with excellent records, and each calls for a different approach.
The three postures, and what each costs
Broadly there are three ways to sit. You can treat it as a commercial conversation and keep negotiating. You can treat it as a dispute and prepare properly. Or you can do neither, which is what most parties actually do, and wait to see which way it goes.
The third posture is the expensive one. It produces correspondence written in a commercial register that will later be read in a forensic one, and it leaves the records exactly as thin as they were when the issue arose. Waiting costs nothing until the day it costs a great deal.
Choosing deliberately between the first two does not commit you to either outcome. Preparing a position is not the same as serving a notice, and parties that have done the preparation settle more often, not less, because they know what they are giving up when they concede a point.
Why the point passes unnoticed
Nobody involved wants to be the person who escalates. Commercial teams are measured on relationships as well as on recovery, and declaring a dispute feels like an admission that the relationship has failed. So the language stays warm while the positions harden, and the moment passes.
There is also optimism. Most people in construction have seen difficult accounts settle at the last minute, and that memory encourages the belief that this one will too. Sometimes it does. The problem is that preparing for a dispute and hoping for a settlement are not alternatives, and treating them as though they are leaves you unprepared if the hope fails.
Behaving well in both directions
Recognising a dispute does not mean declaring war. The practical response is quieter than that: write more carefully, record the sequence of events while people still remember it, read the contract provisions that apply, and establish whether the position is sound.
None of that damages a negotiation. A party that understands its own entitlement negotiates better, because it knows which points it can concede and which it cannot. The alternative, negotiating from a position you have not tested, is how accounts get settled on fatigue rather than on merit. If the account is already deadlocked, that is final account dispute review work rather than a review of one issue.
The discipline that prevents most of this is ordinary commercial management during the works: valuing change as it happens, notifying properly and keeping records that mean something. That is cost control and variations work, and it is considerably cheaper than the alternative.
Not sure whether the claim is worth running?
An initial dispute review reads the contract and the correspondence, tests whether an entitlement exists and tells you what the dispute is likely to absorb before you commit to it.
