Case Study · 100 Bishopsgate
Built by the 100 Bishopsgate Partnership, a joint venture between Brookfield Office properties and Great Portland Estates, and designed by Allies and Morrison, who had previously worked together on City Place House, 55 Basinghall Street; 100 Bishopsgate sits in the eastern edge of London’s financial district, a stone’s throw from landmarks such as the Gherkin.
We installed 101Nr FCe30 flame resisting fire curtain systems, fully compliant with BS EN 1634-3 (smoke leakage); giving 30-minute (integrity) rating; complete with the much desired- galvanised steel curtain housing, and satin finished stainless steel bottom rail and guide rails, across both sites. 30-minute integrity rating ensures that temperatures on the surface of the fire curtain are greatly reduced, for 30 minutes up to 1000°C, to allow for safer evacuation of inhabitants.
Due to the high-end quality of the building, and the focus on panoramic views and high-quality, open concept office spaces, BDL Dry Lining were keen to ensure that fire safety products did not interrupt the design aesthetic of the interior, but still provided the necessary fire safety requirements for each structure. This meant that the stainless steel headboxes and guides had to remain flush with the building’s interior.
We successfully installed all systems on time
Our relationship with Brookfield Properties continues with servicing and maintaining the fire curtain systems in-situ.
Alongside Brookfield Office Properties and Great Portland Estates, Allies and Morrison; Adexon worked with Multiplex as the main contractor, who we have partnered with before to complete a project for multinational investment bank Goldman Sachs; and BDL Dry Lining who have esteemed standing within the market because of previous prestigious London projects such as BBC worldwide HQ and Paddington Square.
100 Bishopsgate and 15 St Helens Place provides over 10,033,060 sqft of net lettable space and was referred to in The Guardian as the “UKs most expensive office block.” with a build-price upwards of £400 million.
The dual- building site spans between St Ethelburga’s Church and Camomile Street and is one of the largest commercial buildings in London with open plan office spaces, for eminent clients such as The Royal Bank of Canada and Paul Hastings LLP.
100 Bishopsgate required the timely installation of a large quantity of fire curtains to compartmentalise the building and ensure that fire could not spread from floor-to-floor, in a manner that did not impede on design aesthetics.
This required the application of non-standard galvanised steel curtain housing, and satin finished stainless steel bottom, and guide, rails.
