A recent article in Concrete Magazine featured an innovative two storey off-site engineered hybrid concrete structure constructed in Durham provides a new data, IT and marketing office for City Electrical Factors (CEF).
For the building, which has a 2100m² plan area, FaulknerBrowns Architects chose structural concrete as the principal construction material, including the roof structure. Main contractor Sir Robert McAlpine won the tender competition to bring the design to life and PCE Ltd put forward an off- site engineered hybrid structural design, using its ‘kit of parts’ approach to develop a bespoke solution that met the overall design requirements for the project. The hybrid concrete frame has enabled the architect to achieve both functionality and aesthetic excellence
"This provides a low-waste, fast programme and cost-efficient approach."

PCE's GT flooring system was utilised for the precast concrete flooring and roofing units according to the report,
"...which was initially developed to provide a long (up to 16m), clear-span option for car parks and has been extensively used for such."
