Project Overview
Proton Built Environment was appointed to carry out the CAT B refurbishment of 20,000 sq ft of commercial office space at Exchequer Court, London. The project spanned the 1st, 3rd, and 5th floors and involved transforming these areas into modern workspaces with partially exposed services in circulation spaces, break-out areas, and the reception.
The project included creating cellular office spaces, meeting rooms, flexible working booths, a tech bar, and various tea points. In addition to the office fit-out, the refurbishment extended to welfare amenities, including showers in the basement and the refurbishment of WC facilities on the 3rd and 5th floors.
​
Scope of Work
The CAT B refurbishment involved extensive work to upgrade and modernise the office areas while ensuring functionality and aesthetics. Key elements included:
-
Office & Reception Fit-Out: The creation of office spaces, a refreshment bar, and a reception area with modern design elements like feature walls, full-height wardrobes, and black slatted ceilings.
-
Welfare Facilities: Construction of basement shower facilities, refurbishment of WCs, and installation of an executive WC on the 3rd floor.
-
Smart Technology Integration: Specialist installations such as TopBrewer Scanomat smart-tech coffee machines, controlled through iPads or iPhones, enhanced the modern, tech-driven environment.
-
Mechanical & Electrical Upgrades: Full coordination of the M&E services, including integration with the existing building management system (BMS), life safety systems, and HVAC.
​
Challenges & Solutions
One of the primary challenges was ensuring business continuity in a live building with a functioning reception below the construction site. This required precise planning and coordination to manage noise levels and maintain building operations without disruption.
Solutions:
-
Phased Noise Control: Proton Built Environment worked closely with the building management team and the client to devise a noise control plan that restricted noisy works to specific times of the day.
-
M&E Changeover Plan: A detailed mechanical and electrical changeover program was developed, incorporating temporary life safety systems to ensure compliance and continuous operation during the construction phase.
​
Conclusion
The Exchequer Court CAT B refurbishment was successfully delivered on time and within budget, transforming the office spaces into functional, modern environments while ensuring minimal disruption to ongoing operations. Through careful coordination with the project team and innovative design solutions, Proton Built Environment met all of AmTrust International's requirements.
