Project Overview
Comprehensive plant room upgrade and mechanical infrastructure works within the iconic Walkie-Talkie building. Semper Services delivered critical upgrades to pumps, valves, and heat exchangers while managing complex environmental and logistical constraints within a live, high-prole City of London environment.

Scope of Works
Replacement of primary pumps and isolation valves
Installation of new Plate Heat Exchangers (PHEX)
Complete plant room decoration and nishing
Installation of new safety walkways and access systems
Upgrade of associated mechanical elements
Solution / Delivery
To address environmental constraints preventing standard drainage, we implemented a specialist water management strategy.
Deployment of tankers for temporary water storage
Phased system draining and relling procedures
Strict environmental compliance management
Just-in-time logistics for plant replacement
Outcome
The project delivered a fully upgraded and compliant plant room environment with enhanced mechanical reliability. By eectively managing complex environmental challenges and water storage logistics, Semper ensured critical upgrades were completed without compromising the building's operational or environmental standards.
