We're currently seeking an experienced Mechanical Construction Manager to play a key role in the delivery of a £30 million data centre retrofit project in Slough.

This is a critical position within a live or partially live environment, requiring someone who understands the challenges of upgrading and integrating mechanical systems while maintaining operational integrity. The role demands a hands-on leader with a strong background in mission-critical or highly serviced environments.

Key responsibilities include:

• Managing day-to-day mechanical construction activities across HVAC, chilled water, CRAH/CRAC systems, pipework, and associated infrastructure
• Coordinating retrofit and upgrade works within a live or phased data centre environment
• Driving programme delivery, ensuring works are completed in line with key milestones and sequencing constraints
• Overseeing subcontractors to ensure compliance with design, specifications, and quality standards
• Implementing and enforcing HSE standards, particularly within high-risk and operational environments
• Supporting and managing commissioning readiness, including system checks, pressure testing, and pre-commissioning activities
• Working closely with electrical, CSA, and commissioning teams to ensure integrated delivery
• Identifying and mitigating risks associated with retrofit works, access, and system tie-ins
• Attending and leading site meetings, progress reviews, and coordination workshops
• Reporting progress, risks, and performance to senior project stakeholders
