Executive Summary

Our case study covers the delivery of a major glass roof replacement and refurbishment. 

Glazing Refurbishment is proud to work with some of the world’s biggest brands, providing them with a high-level service from the start through to the very end. This was a program that was an amazing opportunity to recognise the challenges of this project and overcome those challenges whilst delivering our considerable works package both safely and timely, not to mention securely fulfilling our client’s needs in the process.


The International Centre for Business & Technology (ICBT) is a cornerstone in the delivery of BP’s business worldwide. Located in Sunbury-on-Thames, Greater London, the ICBT is ‘home’ to some 3,500 people from across the globe, working in more than 55 different international business teams. It is also arguably the most diverse location in the world for BP with more than 50 different nationalities, most major world religions represented and on any given day some 30 languages can be heard. 

The ICBT site has been part of BP’s history for nearly 100 years, starting as a collection of laboratories. Today the ICBT site is a modern, international business centre with upstream, corporate and functions and downstream businesses all represented here including North Africa, Angola, Reservoir Development, HR, IT&S and Shipping to name a few. The site is also home to BP’s eastern hemisphere upstream learning centre designed to help develop petro-technical capability at BP.

Project Summary 

8 High-Level Rooftop Glass Replacements One of the most significant aspects of the project scope was the delivery of 8 high-level glass replacements in various locations on the roof area located on the above elevation. 

The work required the removal of the existing aluminium Brise Soleil profile an architectural feature of the building that reduces heat gain within that building by deflecting sunlight. 

We then had to clean the entire rooflight removing over 20 years of dirt and grime before our survey team was able to identify the defective DGU’s 8 in total. 

The work area was cleared of all the defective Brise Solei profile before our Glazing Technicians started their removal and replacement mobilisation, 

We worked with our clients CBRE and BP to deliver another winning project from our GR South Team. 

Project Scope 

  • The provision of specialist glass lifting equipment 
  • IRATA trained rope technicians to complete the replacements. 
  • Removal of dated Brise Solei profile 
  • Removal and of existing defective pressure plates and cover caps. 
  • Removal and replacement of defective 8 No DGU’s 
  • Ground and roof marshalling and cordoning for job duration was vital as all works needed to be completed without impacting the 3000 staff located at BP.

Glazing Refurbishment was able to bring together and deliver a scope of works that pleased our customer and fit well within the budget constraints that are often faced on such large and complicated jobs. 

This work fits in with our growing case studies, which can be found on the GR website. GR’s IRATA trained technicians were deployed on such a significant portion of the work due to the difficult rooftop access at BP. Following IRATA's safe rope access system method meant that all glass replacement, inspection, and cleaning work could be included in this bespoke solution without putting any valued employees or healthcare workers at risk. 

Vacuum Lifters Completing Glazing Replacement Work 


We have successfully maintained and repaired the glazing at many high-profile businesses and facilities throughout the UK for the past twenty-eight years. Some of our most challenging projects come in all shapes and sizes. While some are the standard jobs we complete every week, others are more challenging and complex. These challenging projects are the ones that use a lot of time and resources, and really push business resources you to the limit. For these reasons, many companies avoid them, instead preferring to focus on easier projects. At Glazing Refurbishment, we love a challenge. We believe in taking on projects that inspire us; the ones you can’t stop thinking about even when you’re finished for the day. It’s not that we need extra motivation far from it but we’re at our best when we’re put under pressure by a demanding yet energising project. It’s not just the inspiration that draws us to these projects, though. Over the years, we’ve recognised the many additional benefits that come with successfully completing demanding jobs.
