Construction Disputes, Variations, and Final Accounts — Protecting Yourself When Things Go Sideways

So folks, I want to talk about something that nobody wants to talk about.

What happens when a construction project goes sideways.

Not the theory of it. Not the legal framework. The reality of it — what it feels like, what it looks like, and what you can actually do about it if you find yourself in the middle of one.

Because the reality is this. Disputes happen. On good projects with good builders and good architects and good homeowners who all wanted the same thing. They happen because construction is inherently uncertain — you open up a floor and find something nobody expected, you change your mind about a finish halfway through, the builder's programme slips for reasons that are genuinely nobody's fault. And when those things happen, money is at stake. And when money is at stake, people get stressed. And when people get stressed, communication breaks down.

I know what it feels like to be in the middle of one. I have sat across the table from homeowners who are exhausted, angry, and frightened. And I have sat across the table from builders in the same position. And almost always, the dispute was not really about the money. It was about the feeling that someone had not kept their word.

That is where I start. With the feeling. And then we work backwards to the facts.

Variations — the most misunderstood word in construction

Most disputes on residential projects in Ireland begin with variations. Not with fraud. Not with incompetence. With variations.

A variation is any change to the agreed scope of works after the contract is signed. The homeowner decides they want a different floor finish. The engineer discovers something unexpected in the existing structure that requires additional work. The builder raises something that was not on the drawings but needs to be done.

Variations are not the enemy. Variations are inevitable on almost any residential project. The problem is not the variation. The problem is the unmanaged variation — the change that was agreed verbally on site, not written down, not priced at the time, and not discussed until it appears on the final account as a line item that nobody remembers agreeing to.

The way to manage variations is simple in principle and often difficult in practice. Every variation should be instructed in writing, priced before the work is done, and agreed by both sides before it is added to the contract. On a well-run project with a good contract administrator, this happens consistently. On a project that is moving fast, under pressure, with a homeowner who is living in the middle of the works — it often does not.

If you are currently on a build and variations are being agreed verbally on site, stop now. Put it in writing. A simple email confirming what was agreed, the cost, and who instructed it. That email may be the most valuable thing on the project.

What to do tonight, this week, this month

If you are reading this and you are already in the middle of a dispute, here is the practical path.

Tonight — gather everything. Every contract document. Every drawing. Every specification. Every email, every text, every WhatsApp message that relates to the project. Every site meeting minute. Every variation instruction, written or verbal. If the dispute ever goes to formal proceedings, this is your evidence. Start organising it now, while it is still retrievable.

This week — stop the informal communication. If you have been managing the project through phone calls and site conversations, move everything to email from this point on. A paper trail is not bureaucracy. It is protection. Every significant conversation should be confirmed in writing within 24 hours.

This month — get independent advice before you make any major decisions. Before you dismiss the builder. Before you engage a solicitor. Before you make any payment that you are not certain about. Talk to a QS who is not connected to the project and get an independent view of where you stand.

I'll be honest with you. The most expensive mistakes I see homeowners make in disputes are the ones made in the heat of the moment — dismissing a builder without following the contract procedure, withholding payment beyond what the contract allows, or making concessions under pressure that they later regret. The contract governs all of these situations. Understanding what it says before you act is the single most important thing.

The role of the QS in a dispute — and why it is different from the solicitor's role

When a dispute escalates, the instinct is often to reach for a solicitor. And sometimes that is the right move. But a solicitor and a QS play very different roles in a construction dispute, and understanding the difference matters.

A solicitor advises on the legal position. What rights you have. What remedies are available. What the contract says in legal terms.

A QS does something different. A QS reads the project — the scope, the programme, the costs, the variations, the payment history — and tells you what the numbers actually mean. What was agreed. What has changed. What the fair value of the disputed work actually is. What a reasonable final account should look like.

Most construction disputes are not primarily legal disputes. They are disputes about what was agreed, what was done, and what it is worth. A QS can often resolve those questions — or at least bring clarity to them — without the need for formal legal proceedings.

And formal legal proceedings are expensive. Really expensive. In my experience, the parties who end up in adjudication or litigation on a residential project in Ireland almost always spend more on the process than they recover from it. The goal, almost always, is to find a fair resolution before it gets there.

That is what I do. I look at what both sides are saying. I measure the gap between them. And I help find a number that both sides can live with — win-win, even at the end.

The final account — how it should work

Every construction contract ends with a final account. It is the moment where all the costs are settled — the original contract sum, plus all the agreed variations, plus or minus any adjustments for provisional sums and PC sums that have been opened during the build.

On a well-run project, the final account is a relatively straightforward exercise. Both sides have kept records. The variations have been instructed and priced properly. The provisional sums have been opened and closed with agreed figures. The final account is a reconciliation of what was agreed at the start against what was actually built.

On a project that has run into difficulties, the final account is where the dispute crystallises. Both sides have a number in their heads. Those numbers are different. And the gap between them is the dispute.

Preparing a final account properly — fairly, based on the evidence, with a clear structure that both sides can follow — is one of the most valuable things I do. Not to win an argument. To settle one.

Win-win. That is the only way I work. Even at the end of a difficult project, a fair final account that both sides can accept is worth more than a legal battle that neither side can afford.

What the Dispute First-Aid Kit covers

I have put together a one-page guide — the Dispute First-Aid Kit — that covers what to document in the first 48 hours of a dispute. It is not a legal document. It is a practical checklist for homeowners and clients who find themselves in a situation they did not expect.

Download it below. And if you are already in the middle of something and you want an independent view of where you stand, send me what you have. I will tell you what I see.
