Why Technical Risk Must Be Connected to Commercial Risk
A technical risk register and a commercial risk register that are never read together will each look reasonable on their own — and still miss the risks that matter most.

Two registers, one underlying risk
Most projects maintain separate risk registers: a technical risk register, owned by the engineering team, covering design uncertainty, ground conditions, performance risk; and a commercial risk register, owned by the contract or commercial team, covering cost exposure, contractual entitlement, claims risk. Each is usually well maintained in isolation. The problem is that many of the risks that most threaten a project's outcome are the same risk, viewed from two sides — and if the registers are never reconciled, that risk can be significantly understated in both.
How risk gets lost in the gap
A ground-condition risk sitting in the technical register might be assessed as moderate because the engineering consequence, taken alone, is manageable. The same risk, assessed for its commercial consequence — the compensation event it would trigger, the contractor's likely claim, the knock-on programme cost — might be severe. If neither register captures both dimensions, the true scale of the risk is never visible to anyone making decisions about it, and it is only fully understood once it has already materialised.
Bringing the two together
The fix is not complicated in principle: significant risks need a combined assessment that captures both technical and commercial consequence, reviewed by people who understand both dimensions, not simply merged spreadsheets. This usually means a joint risk review, held regularly, where technical and commercial leads assess the top risks together rather than reporting on them separately to different audiences.
This is often uncomfortable in practice, because it requires technical and commercial teams to have a shared, sometimes difficult conversation about risks that neither side wants to own alone. But that discomfort is far cheaper than discovering the true scale of a combined risk after it has already crystallised.
Our view
Bringing technical and commercial risk together into a single, honest assessment is a core part of how we support clients through our engineering consultancy and contract management services.
