The Role
An excellent opportunity for an experienced Mechanical Construction Manager to join a major hyperscale data centre development, overseeing the delivery of critical mechanical systems within a fast-paced, technically demanding construction environment.
This role is suited to a construction professional with a strong background in large-scale data centre or mission-critical projects, combining hands-on site management, contractor coordination and technical oversight to drive installation quality, programme performance and commissioning readiness.
The Role
Working closely with the General Contractor, mechanical subcontractors and wider project team, the successful candidate will oversee mechanical construction activities from design coordination and procurement through installation, testing, commissioning and handover.
The position will play a key role in ensuring mechanical systems are installed to the required quality standards, construction activities remain aligned with project milestones, and technical or programme-related issues are identified and resolved at the earliest opportunity.
Key Responsibilities
- Review mechanical issued-for-construction designs to establish scope, identify potential installation challenges and highlight design discrepancies requiring resolution.
- Support the development and review of mechanical shop drawings, monitoring progress against programme requirements.
- Assist with technical reviews of proposed materials and equipment, tracking approvals and procurement to ensure timely delivery to site.
- Monitor mechanical installation activities, ensuring appropriate labour, plant, equipment and resources are available to maintain construction progress.
- Undertake regular site inspections to monitor workmanship, installation quality and compliance with project specifications and required standards, minimising defects and rework.
- Coordinate mechanical subcontractors and the General Contractor to resolve access constraints, construction interfaces and sequencing issues.
- Develop and monitor short‑term construction programmes and labour forecasts, implementing recovery plans where progress falls behind schedule.
- Support the preparation and review of method statements and assist site teams in resolving technical and installation queries.
- Develop mechanical flushing strategies and associated method statements, coordinating system readiness ahead of testing and commissioning.
- Conduct mechanical system walkdowns to verify installation completeness and readiness for testing.
- Oversee mechanical testing and commissioning activities, including pressure testing, leak testing, flushing, cleaning and balancing.
- Coordinate with specialist equipment suppliers to ensure installation, testing and commissioning requirements are understood and achieved.
- Support the commissioning of mechanical systems through advanced commissioning stages, working closely with contractors and commissioning specialists.
- Ensure mechanical systems outside the primary commissioning team's scope,
including plumbing, office‑area testing and balancing, fire suppression and external building HVAC, are properly tested, commissioned and documented.
- Drive the resolution of outstanding defects and commissioning issues, supporting final inspections, system acceptance and handover.
- Share technical expertise and project experience with mechanical contractors to promote consistent installation standards and continuous improvement across project phases.
Candidate Profile
- Significant experience in mechanical construction management on large-scale data centre or mission‑critical projects.
- Strong technical knowledge of chilled water systems, HVAC, plumbing, fire protection and associated mechanical infrastructure.
- Proven ability to manage mechanical subcontractors and coordinate installation activities within complex construction programmes.
- Experience reviewing mechanical drawings, shop drawings, material submissions and installation methodologies.
- Demonstrable expertise in construction sequencing, resource planning, programme recovery and site progress monitoring.
- Strong understanding of mechanical testing, flushing, pressure testing, testing and balancing, and commissioning processes.
- Experience supporting integrated commissioning programmes and working with commissioning teams, specialist contractors and equipment suppliers.
- A proactive, hands‑on approach to site management, with the ability to identify technical issues early and drive practical solutions.
- Strong communication and coordination skills, with the confidence to engage effectively with site teams, contractors and senior project stakeholders.
