The Subcontracts Senior Manager will lead the overall subcontracting strategy and execution for the project, with responsibility for shaping, procuring, awarding, and managing the project’s major construction and supporting service subcontracts.

• Recommend optimal contract size, scope split, and contracting models to suit project needs and contractor capability.
• Ensure subcontracting strategy supports execution certainty, cost and schedule performance, and risk mitigation.

2. Market engagement and sourcing

• Lead early market engagement with key subcontractors and construction service providers.
• Develop bidder and contractor longlists/shortlists for major and minor work scopes.
• Assess market appetite, resource availability, competitiveness, and delivery capability in the UK construction environment.
• Shape sourcing strategies for critical packages, including competitive tendering, selective tendering, single-source, and ECI approaches where justified.

3. Prequalification and tendering

• Direct preparation of package-specific tender strategies, invitation-to-tender documentation, tender evaluation criteria, and award recommendations.
• Ensure technical, commercial, financial, HSE, and execution considerations are fully integrated into bid evaluation.
• Lead or govern negotiations with preferred subcontractors.

4. Commercial model and contract form selection

• Recommend appropriate commercial models for each package, including:
  • lump sum
  • remeasurable
  • target cost
  • reimbursable
• Ensure contract forms and commercial structures are aligned with scope maturity, risk profile, market conditions, and delivery objectives.
• Develop contractual approaches that are bankable, practical, and attractive to the market while preserving required risk protections and flowdowns.

5. Contract formation and governance

• Lead preparation, alignment, negotiation, and execution of bespoke subcontract documentation.
• Ensure key head contract obligations and project-specific requirements are appropriately flowed down.
• Maintain full compliance with governance, delegation of authority, ethical sourcing, confidentiality, and applicable company/client procedures.
• Support governance approvals and recommendation-for-award processes.
• Establish the contract management framework for awarded subcontracts.
• Oversee subcontract performance monitoring, KPI development, reporting, and contractor governance.
• Drive robust administration of change, claims, notices, disputes, and commercial close-out.
• Ensure early identification and management of commercial, delivery, and interface risks.
• Work closely with project management, construction, engineering, procurement, legal, HSSE, project controls, and client teams.
• Interface with strategic suppliers and major package stakeholders where broader contractual arrangements or bridging mechanisms are required.
