Case Study - Plant Replacement

Service: Project Management & Building Surveying
Sector: Commercial Office
Location: Central London

We were appointed to manage the replacement of ageing boiler plant and the upgrade of Air Handling Units (AHUs) within a fully occupied multi-tenant office building.

The key constraint was clear: the building had to remain fully operational throughout the works. Any interruption to heating or ventilation would have directly impacted tenant business continuity.

We developed and implemented a phased delivery strategy, replacing systems in carefully planned sections rather than undertaking a full shutdown.

Our role included:

• Project scoping & methodology development – defining a practical, safe, and efficient approach to delivering works in a live environment
• Stakeholder coordination – acting as the central point of contact between managing agents, tenants, and the project team
• Tenant liaison – maintaining clear, proactive communication to minimise disruption
• Programme management – sequencing works to ensure continuity of services at all times
• Cost control – agreeing project costs, managing variations, and certifying completed works
• Progress reporting – issuing regular weekly updates to all stakeholders

• Phased boiler and AHU replacement with zero full-building shutdown
• Continuous occupation maintained throughout
• Close coordination with managing agents and multiple tenants
• Live environment risk management and mitigation
• Central London logistics planning

The project was delivered successfully with no disruption to tenant operations, demonstrating the effectiveness of our phased approach and stakeholder management.

• ✔ Critical building services maintained at all times
• ✔ Works delivered to agreed cost and programme
• ✔ Improved system performance and energy efficiency
• ✔ Positive engagement from tenants and managing agents
