As nationwide M&E design and build specialists, our team understand that the true measure of a building’s performance begins when it becomes operational. That is why our approach to MEP commissioning and handover is built around ensuring every system performs efficiently, reliably and intuitively from day one.
Successful outcomes start long before construction begins and by engaging early with architects, main contractors and facilities management teams, our in-house design specialists ensure building services are aligned with operational requirements, long-term maintainability, performance targets and the needs of end users. Specialist commissioning engineers are involved from the outset, establishing clear objectives and helping to avoid costly changes later in the programme.
Rather than viewing commissioning as a final-stage exercise, Derry Ltd integrates quality assurance throughout the entire project lifecycle. Working closely with the main contractor, the team develops a detailed programme covering every phase of delivery, from design and procurement through to construction, commissioning, training and handover. Progress is monitored collaboratively across the project team, ensuring a coordinated approach and maintaining quality at every stage.
Tailored commissioning packs are produced for each discipline, providing a structured process for review and sign-off by clients, commissioning managers and the professional team. This methodical approach helps ensure systems are thoroughly tested, documented and ready for operation.
Throughout construction, Derry Ltd actively engages with building operators and facilities management teams to ensure a smooth transition into occupation. Dedicated system presentations are delivered before services are concealed, providing valuable familiarisation and clear understanding of critical components, including emergency isolation points.
To safeguard performance and maintain manufacturer warranties, Original Equipment Manufacturers (OEMs) are engaged to support plant commissioning, validation and operator training. Depending on client requirements, structured on-site training sessions can be delivered either before or after practical completion, supported by a soft landings approach that provides continued assistance beyond handover.
By combining early engagement, rigorous quality control and ongoing support, Derry Ltd ensures every MEP project is handed over with confidence. This integrated approach enables clients to benefit from buildings that are efficient, dependable and designed to perform from the moment they open.
