In short, we look after the money on a construction project — estimating costs before work starts, managing the budget as it progresses, valuing the work that's done, and settling the final account so everyone pays, and gets paid, the right amount.
If you're spending a meaningful sum on a build or extension, a QS protects that spend — an accurate budget at the outset, and an independent check on what you're billed as the work goes on. Many private clients find good cost control saves more than it costs.
The earlier the better. Involved at design stage, we can shape the budget before decisions become expensive to change — but we're happy to pick a project up at any point.
Everything between deciding to build and getting the keys. We help you settle the brief and the budget, appoint and coordinate the architect, engineer and other consultants, run the tender and choose the builder, then manage programme, cost and quality through the build to handover. You get one accountable person who reports to you in plain figures — so you're never the one chasing the builder or refereeing between consultants.
Not always — on a small, simple job the architect may look after it. But on anything with real money at stake, a project manager is the only person whose job is your interests across the whole project. The architect designs, the builder builds, and someone has to hold the programme, the budget and the decisions together. Because we're quantity surveyors first, cost control comes built in rather than bolted on.
Yes. It's more common than you'd think — a build that's over budget, behind programme, or where the relationship with the builder has soured. We review where things stand, get the figures straight, and take the day-to-day management off your hands.
It depends on the project and the scope of work. We'll always agree the basis with you — a fixed fee or agreed dayworks — and set it out clearly before anything starts.
