Chobham Manor

OVERVIEW

Introduction


The Keyfix Non-Combustible Cavity Tray System has played an important role in futureproofing a major new residential development in Stratford’s Olympic Park by exceeding new building regulations whilst improving build quality and installation efficiency on site.


Overview


Located in the very heart of the Queen Elizabeth Olympic Park, Chobham Manor in East London is the first of five new neighbourhoods in the former home of the 2012 Olympics. Comprising 850 new one, two and three-bed homes alongside community facilities, shops, public green spaces and community areas, this stunning new development has sustainability at its core with all homes built to the Code for Sustainable Homes Level 4.


In a design by JSA Architects and built by Taylor Wimpey, the layered brickwork façade features projected bay windows, balconies and set back terraces. To meet the requirements and a tight build programme, Keyfix worked with subcontractor Chine Brickwork and supplied 4545 metres of Keyfix Non-Combustible Cavity Trays (NCCT) along with Corner Units and Weeps on blocks A, B and C which form Phase Four of the development.


Challenge


The challenges for Keyfix were the unique brickwork build programme which incorporated two runs of cavity trays being supplied per floor to accommodate brickwork corbelling and recessed brickwork.


Solution


As the corbels where built at a different stage on the build programme so the Keyfix Non-combustible Cavity Trays had to project out either side of the pier when initially being installed. Therefore, when the infill corbels where being built the continuous run of tray could link in seamlessly. A task that would have been near impossible had the system relied on tapes or mastics to make the linking joint.


The Keyfix stainless steel NCCT was specified due to its self-supporting system which doesn’t need fixing back to the internal concrete frame and clips together for fast and easy installation. It is essentially a ‘Fix & Forget’ solution with no additional fixings, sealants or onsite fabrication required by the brickwork contractor. Therefore, installation of the trays did not impede the speed of bricklaying even when compared to traditional DPC. Installed in the outer leaf with no connection with the inner skin, this innovative cavity tray system does not create a thermal bridge and eliminates all differential movement issues.


With a lifespan of 125+ years it is the only non-combustible cavity tray system that does not rely on tapes and mastics to make watertight joints, therefore elimating one of the main reasons for product failure.


Commenting Kieran Coyle of Keyfix said: “Holding an A1 Fire Rating, the Keyfix non-combustible cavity tray solution exceeds the minimum standards set out in ADB (Approved Document B), whilst ensuring this new development meets and exceeds the latest regulations. If the regulations become stricter, it will also be futureproofed maximising the whole-life value of the development.”


The award-winning Chobham Manor Phase Four is now complete, with the Keyfix Non-combustible Cavity Tray playing an integral part in the creation of a safe and resilient development that will transform the Olympic Park into a lasting legacy for East London.
