If you wait for the tender to test the design, you’re already late.
More and more “buildability” is treated like it’s the contractor’s problem, something to be flagged after the drawings are issued and the price is fixed.
At that point the Client has already paid the price for it.
Design choices that look good on paper but are expensive to construct
Value engineering that comes after the value’s been lost
Details that clash with the reality of sequencing, plant, or logistics
Rework and change driven by assumptions that could’ve been challenged earlier
Buildability isn’t a stage it is a state of mind. It needs to be baked into design, not bolted on at tender stage.
What helps:
Early contractor involvement (NEC4 X22) aligned with design development.
Designers walking the site with the contractor, not just working from models
Joint reviews of sequencing, access, and temporary works
Clients encouraging practical challenge, not just aesthetic ambition
Everyone benefits when design reflects how things actually get built.
It’s faster, cheaper, safer and far less adversarial.
Let’s stop waiting until it is tool late to ask “Can we actually build this?”
Funding for schemes is getting a lot more competitive. Buildability issues are low hanging fruit.
Let’s cut them out early and protect value from day one.
How are you building buildability into design on your design processes?
What checkpoints or feedback loops work on your projects?
I would love to hear them.
