Why single-source cladding D&B reduces main-contractor risk

When you split façade design and installation between two companies, you create an interface. Every time there's a coordination problem, a programme delay or a quality issue, someone has to manage that interface — and that someone is usually you.

1. Coordination failures

Structural frame at ±10mm, panels designed for ±5mm, actual site tolerance ±15mm — and three parties each pointing at the other while your programme slips. When the designer IS the installer, we clash-detect our BIM against your structural and MEP models and design for real-world tolerances. If there's an issue, we own it.

2. Programme slip

Redesign cycles and variation claims are the classic critical-path killers. Catching the conflict in the model — before it reaches site — keeps the package off the critical path.

3. Commercial disputes

Split responsibility means split accountability and contra-charges flying both ways. One contract removes the seam where disputes live.

4. Building Safety Act exposure

Golden-thread gaps at handover are the main contractor's problem. We prepare and hand over this documentation where the appointment requires it — see our BSA article.

5. “Can they carry the package?”

A sub who can design but can't deliver, or deliver but can't design, is half a solution. We've delivered envelopes from £200K to £1.4M+ end to end.
