Procurement route determines how cost, risk and programme are distributed between employer and contractor. It is among the highest-value decisions taken on any project, and among the most frequently rushed — often settled by habit or by whichever route the last scheme used.
Start with the objective that cannot move
Every project has one constraint that genuinely dominates: a fixed opening date, a hard funding ceiling, or a quality standard tied to brand or operator commitments. Route selection should follow from that constraint rather than from general preference.
- Cost certainty dominates — favour routes that fix price against a complete design before commitment.
- Programme dominates — favour routes permitting overlap between design and construction, accepting reduced early price certainty.
- Quality dominates — favour routes retaining employer control over design development and specification.
Test the market before committing
A theoretically ideal route fails if the market will not price it. In a busy market, capable contractors decline routes carrying risk they consider unquantifiable. Assess appetite and capacity before the strategy is fixed, not after tenders return short or heavily qualified.
Allocate risk to the party best able to manage it
Risk transferred to a party that cannot control it is not removed; it is priced, and priced expensively. Ground conditions, statutory approvals and employer-driven change are the usual candidates for retention rather than transfer.
Consider packaging deliberately
How work is divided into packages affects interface risk, programme flexibility and the number of commercial relationships to administer. More packages can improve pricing but increase coordination burden and the potential for interface disputes.
Document the reasoning
A short options appraisal recording what was considered and why the selected route was chosen is valuable well beyond the decision itself. When circumstances change — and they will — that record allows the strategy to be revisited on its original logic rather than re-argued from memory.
