Offsite quality-controlled manufacture ensured the fit of components into the structure on a first-time basis.
PreFastCore System provided safe rapid full height erection of lift and stair cores and led to faster overall structural completion.
The development of the hybrid structure
PCE Ltd were appointed to work on Birmingham’s 17 acre Paradise redevelopment project with a contract value approaching £5 million, to design and build a two storey hybrid structural frame at the city centre location.
The hybrid structure provides a suspended car park level below a podium level that forms the ground floor of two new office buildings, Number 1 and Number 2, Chamberlin Square.
Precast concrete columns, beams, walls, prestressed hollowcore flooring and steel Delta Beam units provide the structural hybrid frame solution with insitu concrete being used where necessary to facilitate structural connections.
Precast units by PCE improve the overall quality of a project with improved accuracy of fit
2,500 offsite engineered units
Over 2,500 precast concrete and structural steel components – manufactured offsite – were erected by PCE’s highly qualified on-site team to form the structure, which PCE delivered on a design and build basis.
The upper level deck structure will also provide the surrounding public realm areas around the buildings linking into the existing landscaping of Chamberlain Square and forming a link between the Square and Broad Street.
All precast concrete components are manufactured under stringent quality control procedures for PCE. Temporary safety balustrading is provided to ensure safe use of the PreFastCore units during main structural frame erection.
The high quality concrete used enables internal wall finishes to be left as struck or directly painted.
“Paradise is to be transformed into a vibrant mixed use development of commercial, civic, retail, leisure and hotel space, providing major improvements to pedestrian access and greatly enhanced public realm befitting this exemplary historic setting”, according to the Paradise Birmingham website.
“Paradise will be one of the biggest development schemes Birmingham has seen for a generation and will dramatically transform this whole area of the city.”
The PreFastCore system
The lift and stair cores were constructed with PCE’s PreFastcore system providing a safe, fast and dimensionally accurate solution for their construction.
PreFastCore is the ideal system for constructing structural lift, stair and combined lift and stair cores, using offsite engineered precast concrete modular units, providing rapid and safe on site erection to full height.
