A sample answer to question 1

What does the role of a construction commercial manager involve, and how does it differ from a quantity surveyor's role?

A commercial manager is accountable for the financial and contractual performance of a project or portfolio, and the role sits above the quantity surveyors who do much of the detailed measurement and valuation. On the contractor side, I would oversee the tender commercial strategy, subcontract procurement and buyout, the monthly valuation and cost value reconciliation, variations and change control, and the final account. I would also manage contractual risk, including notices, extensions of time and loss and expense claims, and advise the project director on how the contract is working. A QS may carry out the measuring, pricing a package or preparing a valuation, whereas the commercial manager sets the strategy, reviews forecasts, protects margin, signs off key commitments and handles disputes. I would also lead and develop the commercial team, and report the financial position to the board. So it is a mix of technical skill, contractual judgement and leadership.

Common mistake to avoid: Describing it as just a senior QS; ignoring leadership and reporting
