Managing mechanical and electrical (M&E) work in live environments requires careful planning and seamless coordination to maintain the integrity of building operations while introducing new systems. At DL M&E Building Services, our experience with live environment projects such as fit outs of National Banks has demonstrated the importance of precise scheduling, phased work areas, and collaborative communication to balance operational continuity with technical upgrades. This approach enables us to deliver high-functioning, resilient spaces without interrupting day-to-day activities.

Why Experience in Live Environments Matters

Working in an operational building presents unique challenges. Occupants’ activities must continue undisturbed, and safety regulations are critical. Each live environment project requires tailored strategies to integrate installations without disrupting the daily functioning of the space. An example of operating in a live environment involved a recent project that had us engaged on roof works on a Ministry of Justice building, which was occupied at the time, but required extensive asset replacement involving crane works.

Having worked very successfully across many live environment projects, DL M&E’s recent MEP refurbishments of National Banks and Public Sector buildings exemplifies our approach. Working closely with banks, we often conduct a Cat B refurbishment that requires meticulous coordination to deliver a modern, user-centric workspace while adhering to the client’s standards for functionality and IT resilience. Effective communication and a carefully coordinated schedule enable us to meet these standards minimising disruption to the building's day-to-day operations. Through efficient live environment project management, our works often earn outstanding praise from the client's consultancy team, citing the exceptional quality of the MEP installation, and commending the proficiency of the delivery team.

Office Fit-Out

In office environments, interruptions impact productivity. Our projects demonstrate an ability to integrate M&E systems within a live setting, enabling operational continuity. We have achieved a balance between delivering a high-quality, functional workspace and minimising disturbance, gaining positive feedback for both the aesthetic and technical standards of our installation.

Key Principles of M&E Operations in Live Environments

1. Early Collaboration and Stakeholder Engagement
   From project conception, we prioritise stakeholder engagement. In live environments, coordinating with building occupants, the main contractor, and facility management is essential for establishing protocols and adjusting workflows based on the building’s daily operations. Early involvement allows us to tailor each project to the unique needs of the site and its users. ‍
2. ‍Clear and Detailed Project Planning
   Successful live environment projects start with detailed, sequenced planning. We define clear project milestones and establish effective communication channels, ensuring every phase is meticulously planned. Our planning process includes scheduling around peak hours, isolating work zones, and managing noise and dust to limit occupant disturbance.‍
3. Health, Safety, and Compliance
   At DL M&E, we never compromise on safety. All live environment projects are risk-assessed and planned according to stringent health and safety standards, aligned with our Client’s own rigorous standards. Our teams are trained in safe work practices that account for ongoing occupancy, safeguarding both our employees and building users. We have an outstanding RIDDOR record ( from the time of publication, having no Lost Time Injuries for the last 2.5 years) and are SafeContractor Approved.

Best Practices for M&E Installations in Live Environments

1. Minimise Disruption to Occupants

• Out-of-Hours Scheduling: Where possible, we schedule disruptive work, such as power-downs or noise-intensive activities, outside regular working hours to avoid interrupting day-to-day operations.
• Phased Installations: By sectioning work areas, we maintain a clean, organised site that isolates work zones from occupants. This approach is instrumental where phased installation allows a project to progress without affecting the building’s ongoing operations.

2. Utilise Temporary Systems

• Backup and Temporary Power Solutions: Maintaining power continuity is crucial. For projects like the National Bank fit-outs, we deploy temporary power sources to ensure that even during transitions, essential systems stay operational, avoiding costly downtime for clients.
• Mobile HVAC Systems: When refitting HVAC systems, we can use mobile units to sustain air quality, ensuring occupants are unaffected during each installation phase.

3. Leverage Technology for Precision and Efficiency

• Building Information Modelling (BIM): We utilise BIM to anticipate challenges before construction begins. This technology enables us to create precise 3D models and foresee how new systems will integrate into existing infrastructure.
• Project Management Solutions: Works are co-ordinated via project management platforms, ensuring seamless communication and lines of accountability throughout a project’s timeline.

Client Collaboration and Transparency

Communication is a cornerstone of our project management strategy. By providing regular updates and maintaining transparent communication, we empower clients and occupiers to make informed decisions throughout the project. For instance, during our healthcare projects, we conduct regular progress meetings to address any potential adjustments based on real-time challenges.
