The risks that cost steel contractors their margin.

Six recurring risks on UK steel subcontract packages. Each one is defendable with the right records discipline — and indefensible without.

RISK · 01

Connection design responsibility

Whose connections — designer's, fabricator's or installer's? Ambiguity here drives the largest variation disputes on steel packages.

Typical exposure£300K+ at FA
RISK · 02

Sequence with concrete frame

Slip in the concrete contractor's programme compounds into steel erection delay. Without EWN discipline, the blame lands on steel.

Typical exposureLADs apply
RISK · 03

EC3 / EN 1090 compliance

Execution-class evidence pack required for every package. Welding records, NDT, traceability — all must be adjudication-ready.

Typical exposureRegulatory
RISK · 04

Fabrication–erection mismatch

Factory output vs site demand misalignment causes stock-out delays or excess material storage costs.

Typical exposure£50K+ / month
RISK · 05

M&E interface — penetrations & routing

Late or unrevised M&E coordination drives drilling, re-cutting, rework. Variation-worthy if recorded; absorbed if not.

Typical exposure£150K+ / project
RISK · 06

Welding traceability gaps

Missing welder qualifications or weld records can void execution-class compliance — and trigger total re-test on critical joints.

Typical exposureProgramme-stopping

The services steel contractors use most.

Steel work is commercial-and-programme heavy. The site delivery and CDM disciplines run in parallel — usually with the QS function leading.

Defend the steel package before it slips.

Steel margins are tight. The £200K of variations on a £10M package is the difference between profit and loss — captured contemporaneously, not at retention.
