Bromley-By-Bow is a visually striking array, comprised of five high rise residential blocks with community spaces and commercial areas at ground level.
Sotech’s newest system innovation – XTR Contour – was chosen as it allowed the design team to mimic the pre-cast concrete fluted panels in a consistent manner.
In order to form the fluted decorative areas below the windows, a new extrusion profile was developed – XTR Contour Concave. The profile of the design was a copy of the pre-cast concrete façade panels which are fluted in the same general locations.
Whilst systemised testing wasn’t carried out on this project, the design team invested significant time in 3D printing profiles to prove concepts prior manufacturing the physical die. This saved time and money in the overall project scheme.
Mohamadrez Jenaban, Technical Lead at Sotech “I have undertaken a number of simulation analyses for this project to ensure panel safety, adequate performance and stability under the given conditions. We were able to determine 1- number of stiffeners required for these panels to keep deflection below CWCT recommendation 2- the maximum fixing span to keep the stress below the material permissible stress value”.
The main challenge on the scheme was implementing a cap to the XTR Contour profiles upon the request of the Fire Engineer. On such a shallow profile this is challenging as there is little room for any form of fabrication works. In response to this challenge, we therefore developed internal screw ports within the extruded profile. This allowed us to mechanically fix plates to the head and the base of the profile and conform the Fire Engineer’s requirements.
Sotech’s was able to provide key advice and guidance in the creation of the XTR profile, as well as key guidance on how to rationalise the arrangement to standardise die quantities, shape and size.
About XTR Contour
The extrusion in the XTR Contour range is formed when the aluminium alloy is pushed through a die into profiles or complex shapes of your choice. All commercial finishes may be incorporated on one elevation to create an almost limitless effect of colours and shapes.
The extrusion range is secretly fixed onto extruded aluminium support framework horizontally, vertically or diagonally. The range can provide the appearance of terracotta cladding but is much lighter, more cost effective, versatile and due to it being made from extruded aluminium 6063-T6 it is extremely hardwearing.
