The ER2i team gives us an update on the progress of the site, structural steelwork, envelope and process.
End of the structural steelwork. The Process building is constructed with a steel frame consisting of WPG (welded plate girders) columns, WPG truss rafters (first storey) and lattice trusses (roof).
Verification of structural bolts. Structural steel connections are primarily made with non-pre-stressed bolts. The manufacture and erection of the WPG columns with a height of more than 15 m were subject to reinforced traceability and inspection procedures (execution class EXC3).
Progress of the roofing and start of the cladding. The metal structure of the Process building is transversely braced by steel portal frames, and longitudinally braced by sway frames on the façade.
Roof bracing and the concrete floor slab provide the diaphragmatic effect and the transfer of horizontal wind and earthquake forces to the portal frames and sway frames.
Cladding with 10 ml sandwich panels.
The façades are constructed of sandwich panels with a rock wool core, providing both the necessary thermal resistance and fire protection.
Casting of the composite floors.
The floor joists are connected to the composite concrete slab with dowels to create composite floors and thus optimize the height of the steel beams.
Cladding completed.
The roofing of the Process building is made from steel decking with insulation and self-protected two-layer bituminous waterproofing.
Installation of the ducts, sprinklers and cable trays for the future clean room.
The structural steelwork has been designed to withstand the heavy loads of suspended networks under the floors.
