Vetting a Concrete Frame Subcontractor: 12 Questions to Ask

By Priya Nair · Apr 24, 2026 · 8 min read

A frame package can be 20 to 30 percent of a build’s value and sits on the critical path. These are the twelve questions that separate a safe pair of hands from a programme risk.

Why the frame package deserves extra scrutiny

A concrete frame is often 20 to 30 percent of a build’s value and sits squarely on the critical path. A weak frame contractor does not just cost money — it costs time you cannot recover. That is why the package warrants harder vetting than almost any other.

The twelve questions

In short: recent comparable projects; references you can actually call; financial standing; directly employed versus subcontracted labour; safety record and accreditations; their proposed pour cycle and the basis for it; crane and temporary works strategy; design and PT coordination capability; concrete supply arrangements; quality and testing regime; how they handle delay and change; and who, by name, will run your job.

Any one of these can be a deal-breaker. Taken together they separate a safe pair of hands from a programme risk wearing a competitive price.

Let the network do the first pass

Vetting takes time most pre-construction teams do not have. That is the point of a curated network: the first-pass checks on experience, accreditation and financial standing are already done, so you start from a shortlist of credible teams rather than a cold market.
