The Role We Want You For

The Commercial Contract Manager is responsible for overseeing all commercial and contractual aspects of a construction project. This role is deployed on designated projects only -- those carrying complex scope, elevated commercial risk, or conditions requiring dedicated contractual oversight. Operating as the single commercial authority, the CCM serves as the key interface between the client, the field, and the subcontractor community, maintaining full visibility of how site events and decisions connect to contractual rights and obligations from contract award through commercial close-out.

The Specifics of the Role

• Commercial and financial management
• Manage project budgets, forecasts, cost control, cash flow, billing, invoicing, and revenue recognition across both owner and subcontractor sides
• Administer contracts under GMP, progressive GMP, or cost-plus structures including allowable cost validation, fee application, and contingency drawdown
• Support open-book commercial processes including cost transparency, backup validation, and client audit management
• Lead commercial reporting, milestone management, and milestone reporting on both sides
• Administer the prime contract in accordance with contractual notice, certification, and response timeframes through a disciplined change order process
• Maintain awareness of daily project activities, linking site events and decisions to contractual requirements and obligations
• Lead contractual assessment of changes, variations, and potential claims including entitlement evaluation, valuation, and tracking through resolution
• Prepare and issue formal correspondence, notifications, and claims to clients and subcontractors in line with contractual procedures
• Ensure all required bonds, warranties, insurances, and commercial undertakings are in place and compliant
• Develop and implement procurement strategies aligned with project delivery goals
• Lead review and negotiation of subcontract terms and variations ensuring consistency with the prime contract
• Oversee tendering processes and bid evaluations; ensure value for money across the supply chain
• Upon joining the project, identify and execute buyout of any remaining scope packages not yet awarded, ensuring full procurement coverage before execution advances
• Identify commercial and contractual risks early, develop mitigation strategies, and maintain risk registers on both sides
• Coordinate with project controls to align change management, cost, and schedule impacts with contractual submissions
• Act as the key commercial interface with clients, consultants, and subcontractors; coordinate with preconstruction at handover as the CCM picks up the owner side at operations
• Lead commercial close-out including final account negotiations, contingency reconciliation, shared savings calculations, and settlement of outstanding claims or variations
• Lead and mentor the Client Commercial Contract Manager, Subcontractor Commercial Management team, and commercial staff
• Collaborate with project managers, finance teams, and legal advisors
• Promote commercial best practices and drive consistency across the project commercial function
  

Requirements

• 5 to 10 years of commercial, contracts, or procurement experience on construction or infrastructure projects
• Hands-on experience administering prime contracts and subcontracts simultaneously on active projects
• Demonstrated experience managing changes, variations, and claims through a formal contractual process
