Key Responsibilities

Pre-Contract

• Prepare and review tender estimates, bills of quantities and cost plans for mechanical, electrical and public health packages, working from drawings, specifications and design information.
• Issue enquiries to the supply chain and subcontractors, then analyse, compare and negotiate quotations to secure competitive and compliant pricing.
• Review tender documents and contract conditions, identifying commercial risks, qualifications and exclusions before submission.
• Support the bid team with value engineering proposals and design development to improve price and programme.

Contract Administration

Variations, Claims and Final Accounts

• Identify, price and submit variations and change orders promptly, ensuring all entitlements are recovered.
• Prepare and negotiate claims for loss and expense, prolongation and disruption, supported by robust records and evidence.
• Agree final accounts with clients and subcontractors, closing out projects on time and without outstanding commercial disputes.

Supply Chain and Procurement

• Build and maintain relationships with key suppliers, specialist subcontractors and manufacturers.
• Manage procurement programmes, working with project teams to place orders in line with long lead-time requirements.
• Monitor subcontractor performance, financial standing and compliance, and resolve commercial disputes constructively.

Leadership and Development
