Infrastructure AdvisoryPractice
Contract & Commercial Advisory
Commercial control across the whole contract lifecycle.
Situations this practice answers
“The performance regime in our contract does not reflect how the asset actually behaves.”
“We are approaching a contract renewal, extension or close-out and need an independent commercial position.”
What we do
Commencement — commercial modelling, negotiation support and commercial process design.
Performance — contract management, cost forecasting, supply-chain and subcontract oversight.
Assurance — cost monitoring, commercial process review and independent investigation.
Close-out — final account, lessons learned and project review.
A performance mechanism written before the asset was in service will eventually stop describing the asset. The question is whether that is found in a review or in a dispute.
Evidence basis
Over 21 years in quantity surveying, contract and commercial management, estimating, project controls and project management, across rail, infrastructure, aviation, retail, leisure and commercial sectors.

On selected commissions, Westheath Infrastructure Advisory can draw on capabilities developed through Westheath Commercial Intelligence — a governed platform for structuring evidence, tracing decisions and supporting auditable commercial assurance.
Its use is commission-specific and subject to agreed scope, data-handling requirements and access controls. It is not included by default.
