Role Purpose

The Commercial Manager will provide commercial leadership and control across a defined package or work area of the Potters Bar Data Centre campus, ensuring robust cost management, contract administration, and commercial governance throughout the design, procurement, and construction phases of this hyperscale, mission-critical development.

Key Responsibilities

• Manage the commercial and contractual aspects of assigned packages (e.g. civils, MEP, HV infrastructure, cooling systems, or building shell & core) from pre-construction through to final account.
• Prepare, negotiate, and administer contracts (JCT, NEC3/NEC4, or bespoke forms) with contractors, subcontractors, and suppliers.
• Produce and maintain accurate cost plans, budgets, cash flow forecasts, and cost reports for senior stakeholders and the client (Equinix/DC01UK).
• Lead on procurement strategy, tendering, and subcontractor/supplier selection for assigned packages.
• Manage valuations, applications for payment, variations, and change control processes.
• Identify, evaluate, and mitigate commercial risk across the programme, escalating issues as required.
• Support the resolution of contractual disputes, claims, and extensions of time.
• Ensure commercial compliance with project governance, CDM regulations, and industry best practice.
• Work closely with project managers, design teams, engineers, and the client's commercial team to align commercial strategy with programme and technical requirements.
• Monitor subcontractor performance against contractual obligations and support final account negotiation and close-out.
• Contribute to monthly commercial reporting, forecasting, and board-level cost reviews.
• Support the wider commercial team in managing the scale and complexity typical of a multi-building, phased hyperscale campus delivery.
