FAQ

Straight answers.

Still unsure? Call the tender desk on +44 114 000 0000.

How fast can you get a price?

An order-of-cost within 10 working days of a site visit. A fixed design & build price usually follows within six weeks, once ground investigation and planning drawings are complete.

Do you only work on design & build contracts?

No. We regularly tender traditional contracts and frame-only packages for other main contractors. Design & build is simply where we add the most value.

What size of project do you take on?

From 5,000 m² extensions to 80,000 m² distribution centres. Below that size we still take steel-frame packages for repeat clients.

Where do you work?

Anywhere within about three hours of Sheffield and Teesside — in practice the North of England, the Midlands and southern Scotland.

Can you build next to our running factory?

Yes. Live-site work is a third of our turnover. We plan possessions with your operations team and agree hygiene, noise and traffic rules before mobilising.

Who owns the design risk?

On design & build contracts, we do — including novated designs. You get one contract, one warranty and one company to call.
