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.
Technology-enabled where it adds value
