testimonial
“James Everdell and the WP3 team are a vital part of Elementa’s professional team. Their diligence, expertise and professionalism are central to how we assess every new location. Customer experience is at the heart of everything we do, and WP3 give us complete confidence that the M&E systems we install will deliver the best possible experience for our members. We’ve worked with many M&E consultants over the years, and WP3 are the only firm we trust with this work. They understand how critical these systems are to our performance.”
Tom Sleigh
Property Director, Landmark Space
“Overbury have engaged the services of WP3 on numerous commercial office projects over the past 5 years. They have undertaken the role of commissioning management, undertaking the planning, witnessing and reporting of building systems.
Notably WP3 managed the Infrastructure Integrated Service Testing on our project for a large American Bank refurbishment in Canary Wharf. The project involved complete replacement of all services back to shell and core, replaced with new HV/MV/LV electrical installation supported by 4no XX MV generation, new chilled water-cooling systems and associated ancillary services for a 1.4 m SQFT head office bank.
WP3 role was to plan and manage the IST. They completed pre test records then managed the switching where the building was supported on generation, recording building status then returning to normal where again recording status. WP3 managed the 40 strong specialist team members provided by the relevant supply chain
Nine test scripts were run “out of hours” as the systems were supporting live comms rooms where the bank was completing user acceptance testing. Each switching operation included capturing xxxx screen shots of BMS/EMS systems and tracking systems returning to steady state after switching.
On completion a fully detailed report was provided on the test scripts and outputs.
The WP3 provided a excellent service and managed to process seamlessly providing the client a comprehensive detailed report on how the building systems performed.”
