If you’re embarking on your first property development project, you may be wondering what exactly is the role of a quantity surveyor (QS) and whether you need one. The short answer? Yes, you do. And here’s why.

A QS is a construction cost expert. Our primary role is to ensure that your project is delivered on budget, with no unpleasant surprises along the way. But that’s only the beginning.

From the earliest stages of a scheme, we provide feasibility advice and cost planning, helping you understand what’s possible with your budget. As your plans develop, we produce detailed bills of quantities or pricing schedules, which form the foundation of contractor tenders. This ensures that pricing is competitive, transparent and benchmarked against market norms.

But it’s not just about estimating costs, we also manage them. We track changes, assess variations, and keep a firm grip on contract administration throughout the build. Our reports give you clear visibility into where your money is going and highlight any risks before they escalate.

At Selway Joyce, we’ve worked with developers of all sizes, from one-off self-builds to large commercial schemes. We pride ourselves on providing clear, jargon-free advice that empowers clients to make informed decisions.

First-time developers often underestimate the complexity of construction procurement and contract law. A QS ensures you’re protected, with the right contract in place, the right procurement route selected, and proper documentation to manage disputes if they arise.

In short, hiring a quantity surveyor isn’t an optional extra, it’s a smart investment. With a trusted QS on your team, you’ll gain confidence, control and clarity at every stage of your project.
