About Our Commercial Manager Contract Roles in London
What does a commercial manager contractor do?
The Commercial Manager contracting discipline covers work within construction and infrastructure projects to manage the commercial and contractual aspects of delivery, protecting the financial position of their employer and ensuring that contractual entitlements are properly identified, substantiated, and recovered. The work includes administering the main contract and subcontracts, managing variations and compensation events, preparing and submitting applications for payment, assessing and responding to claims, reporting commercial performance, and providing commercial advice to the project manager and delivery team. Commercial Managers are brought in on major construction, infrastructure, and engineering programmes where dedicated commercial management is required to manage the contract risk effectively.
The skills expected of Commercial Manager contractors combine deep contractual knowledge with strong commercial judgment and the ability to manage relationships with clients, subcontractors, and project teams under pressure. Thorough knowledge of the relevant contract forms, particularly NEC3 and NEC4, JCT, and FIDIC depending on the project type, is essential. The ability to identify, value, and substantiate compensation events and variations, prepare robust commercial reports, and manage the commercial close-out of a contract are core competencies at this level. Most Commercial Manager contractors have a Quantity Surveying background, with MRICS or MCIOB chartership being well regarded. Experience on projects of comparable scale and complexity to the engagement is typically the primary selection criterion.
