Meeting a Range of Requirements
Designed and planned using BIM by main contractor Sir Robert McAlpine, the Novastruct systems in the two rooftop restaurants were installed by Bennett Architectural.
These included FSX 100 SSG (Structurally Silicone Glazed) curtain walling with regency gold anodised diagrid pressings and FSX 100 capped curtain walling (as clerestory windows) to the John Lewis rooftop restaurant and atrium.
The arcade rooftop restaurant also features FSX 100 curtain wall screens including feature curved glass units in channel glazing. In addition, the upper floor windows of the arcade feature Novastruct’s FSX 100 facetted SSG entrance screens to the new casino and terrace, the ACS framing system to the multi-storey car park screens and doors.
The upper floor windows are also created from a bespoke SSG carrier frame in the concrete sub-frames with bonded glass units and film glazing.
ACME’s director Friedrich Ludewig said: “Anodised aluminium was used throughout the scheme for most of the metal elements and for the glazing and doors. The Novastruct systems met the aesthetic and performance requirements well, especially the curtain walling to the John Lewis restaurant. This was a key design feature that needed to be right.
” Rob Bennett of Bennett Architectural said: “The John Lewis rooftop restaurant presented some significant challenges for the Novastruct FSX 100 curtain wall system as well as from an engineering standpoint. Due to the complex geometry of the diagrid pattern, in conjunction with what was in effect, a freestanding wrap-around curtain wall, our design team had to engineer bespoke connection details, specialist support brackets and a hybrid carrier system that was integrated into the FSX 100 system. We worked in conjunction with a specialist glass engineering company to achieve this innovative solution.”
