New fire protection solution applied at 60 London Wall

Sentinel Contracting is a Billericay based specialist decorating and fire protection contractor focused on developing innovative new solutions that mitigate the impact of works on the environment.

Sentinel Contracting is working with architects and main contractors across London and the South East.  Helping construction projects to mitigate the impact of decorating and fire protection on the environment and to meet WELL building standards, which take a holistic approach to health in the built environment.

60 London Wall: ‘Industry First’ Achieves 80% Less Environmental Impact

One such shining example is the 60 London Wall project, undertaken by Sentinel Contracting on behalf of Skanska.

Reworking a 1980s office building into 20,000 sq. ft of modern retail space and 325,000 sq. ft of prime workspace presents its challenges. Challenges which are amplified when the building is in the centre of London’s financial district, where noise and other environmental restrictions are rigorously imposed.

The building’s original board fire protection was stripped from the structural columns and beams to expose steelwork that would take centre stage in EPR Architects’ new design. This meant that a media blasting solution was required to prepare steelwork for a new decorative fire protection system.

In response Sentinel Contracting developed an innovative new sponge media blasting (a composite of open cell sponge and abrasive) and decorative structural solution.  As the first of its kind in UK construction, this solution resulted in greatly minimised environmental impact of this construction project.  It massively reduced dust and, because it is recyclable, also dramatically cut the actual tonnage of media required compared to other products.

If this system is applied to future blasting works within the UK, the environmental impact of waste media would be reduced up to 80%. That’s 80% less product, 80% less landfill, 80% less delivery cost, 80% less disposal cost.

51 Moorgate: Sustainable and Healthy Workplace

Another stand out project is Skanska’s London HQ, 51 Moorgate, where designers hoped to achieve a modern, sustainable, and healthy workplace where people and businesses can thrive.

Sentinel’s specialist team helped Skanska and architects John Robertson Associates achieve their vision and meet the building’s ambitious WELL Building Standard. Specifically, to ensure materials reduce human exposure to hazardous building material ingredients through the restriction or elimination of compounds or products known to be toxic and the promotion of safer replacements.

Mark Stewart, CEO of Sentinel Contracting says: “The specialist solutions we develop for built environment projects demonstrate that it is possible to greatly reduce the impact of decorating and firestopping on the environment. At 60 London Wall we showed the huge reduction in environmental impact that can be achieved.  Reducing landfill costs alone by £105,000, reducing environmental impact to air quality by 40%, requiring 80% less product, 80% less landfill and 80% less disposal cost.”

Kate Willard OBE, Thames Estuary Envoy and Chair Thames Estuary Growth Board, comments: “Sentinel Contracting work brilliantly in partnership with architects and contractors to meet and exceed important environmental standards across large-scale commercial building projects. Their dedication to reducing environment impact makes them a worthy Thames Estuary Visionary and we look forward to working with them.”
