Commercial Assurance

Independent assurance over costs, commercial decisions and delivery confidence

MJA provides commercial, contract and cost assurance across infrastructure projects, alliances and portfolios. We test the reliability of commercial reporting, compliance with contractual obligations and how effectively controls operate in practice. Our independent challenge helps clients understand their exposure, strengthen governance and protect value throughout delivery.

Test the numbers and the assumptions

We review expenditure, payment assessments, change and forecasts against agreed baselines and contractual requirements. We examine supporting records, commercial assumptions and the treatment of costs, including Defined Cost and Fee where applicable, to identify discrepancies and challenge unsupported positions.

Strengthen risk and opportunity management

We assess how commercial risks and opportunities are identified, allocated, managed and reflected in forecasts. We challenge mitigation actions, contingency use and proposed efficiencies, helping teams distinguish achievable benefits from unsupported expectations and understand the potential impact on cost and delivery.

Understand the wider commercial position

Our reviews consider governance, commercial controls, supply chain arrangements, overheads, profit and incentives, alongside the capability of teams and partners. We connect findings to the decisions facing senior leaders and alliance boards, providing a clearer view of contractual exposure, performance and value for money.

Make findings useful

We provide clear conclusions, prioritised recommendations and practical actions. Working constructively with client and delivery teams, we support agreed improvements and follow up their implementation within our appointment. Our approach combines evidence-based scrutiny with commercial experience, helping clients address weaknesses and strengthen informed decision-making.
