How Quantity Surveying Controls Construction Costs

A quantity surveyor is the financial conscience of a construction project. Their job is to make sure that every pound — or every lira — is spent in the right place and can be accounted for.

Cost planning is where the discipline starts. Before a design is finalised, we model the cost of the building at different quality levels so decisions are made with their price tag already attached.

Bills of quantities then provide a common language between the client and the contractors who bid for the work. They let us compare tenders like-for-like and expose pricing that would otherwise be hidden in lump sums.

During construction, monthly valuations keep payments aligned with the work actually delivered, and careful records mean variations are priced fairly, not opportunistically.

The final account is where discipline pays. A well-managed final account settles the project quickly, with a documented position that both client and contractor accept. Over a lifetime of projects, that is where the biggest savings live.
