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

• Review and negotiate subcontract and supply agreements, ensuring terms are consistent with the main contract and protect the company's position.

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

• Supervise and mentor assistant and trainee quantity surveyors, reviewing their work and supporting their professional development.
• Contribute to the continuous improvement of commercial processes, templates and best practice.

Essential Experience and Skills

• Significant experience as a quantity surveyor within mechanical and electrical contracting, with a track record on design and build projects.
• Proven experience managing M&E packages from tender through to final account on projects of a substantial value.
• Strong knowledge of M&E systems, including HVAC, ventilation, public health, small power, lighting, fire detection and containment.
• A thorough understanding of JCT, NEC and subcontract forms, including payment, variations and claims procedures.
• Proficiency in estimating and cost management software, plus advanced Excel skills.
• Strong negotiation skills, with the confidence to deal with main contractors, clients and the supply chain at all levels.
• Excellent analytical, numerical and report-writing skills, with great attention to detail.
• Excellent communication skills, and the ability to work effectively with project, design and engineering teams.
