What the role covers

John Sisk and Son is recruiting a Commercial Manager for its City of London office. The post leads cost and value management on projects and is answerable for the systems and procedures behind it, for financial reporting and for cash flow forecasting. It carries the negotiation of contract terms, bonds, warranties and guarantees, and the identification of terms the business will not accept. Change is managed by recording and evaluating it and recovering entitlement where the liability does not rest with the company, which places the role inside the contractual argument rather than beside it. Risk and opportunity management is run with the operations team. The post supervises the preparation of cost plans on complex projects, leads the analysis of cost reports, prepares contractual correspondence, and advises on risk allocation, step down clauses and design liability in subcontractor and designer agreements. It prepares and monitors long term cash forecasts, interprets variances and recommends corrective action. It also manages and mentors the commercial team and provides commercial support and training to site staff. The employer asks for proven commercial management experience in construction or infrastructure. The posting is full time. No salary is published and no closing date is stated.
