Architect: Jefferson Sheard
Contractor: HGB Construction/ Nutall
Type of works: installation of bespoke facetted bullnoses and Optima® Cassette rainscreen cladding.
The design of the new Liverpool South Parkway Interchange not only looks stunning but the engineering involved in meeting the architects vision pushed many of the materials and methods of construction beyond what had previously been achieved.
The 3000m2 roof bends in three different directions and is covered in different types of shaped and tapered aluminium sheets that are matched by specially fabricated Sotech bullnoses.
Following a complete stress analysis and working closely with the installers Lakesmere, Sotechs engineering designers used the very latest 3D CAD equipment to ensure the bullnoses were precision engineered to meet the tight tolerances required.
Around 200m of unique facetted bullnoses were fabricated and installed that providing the illusion of a long, smooth curve that perfectly matched the rollercoaster shape of the main roof. Optima interlocking wall planks were used as soffits.
The Interchange links with an existing railway station that has been completely refurbished and it was here that Sotechs Optima cassette rainscreen cladding panels have been installed. The panels, specially re-inforced against impact damage, were factory engineered to accommodate penetrations and to counteract any intolerance within the substructure.
