We modelled the frame in 3D, coordinated the connection details with the engineer, and resolved a clash between the bracing and the mezzanine beams before anything was cut. The frame went out in three loads in December 2024, with Hi-Span purlins and eaves braces after.
We erected the frame in January and February 2025 with rough-terrain booms, working through two machine breakdowns to finish the roof steel.

When the client switched the timber around the stairs and mezzanine to steel, we added two staircases with folded chequer-plate treads, plate stringers and balustrades, installed by May 2025.
