This project showcases the new possibilities in construction that Timberbuilt can provide. Building with curves, irregular shapes or other unusual elements can now be prefabricated off-site to high levels of precision.

Complex structures can be prefabricated off-site, allowing for rapid and economical assembly on-site

  • Soaring curved plywood boxed sections, with concealed metal brackets Soaring curved plywood boxed sections, with concealed metal brackets
  • All plywood box members were manufactured to fine tolerances for efficient installation All plywood box members were manufactured to fine tolerances for efficient installation
  • Plywood box section main members Plywood box section main members meeting on a 5-point hub bracket – all connections were detailed, then modelled in 3D before manufacture

This means assembly is simple and fast, minimising on-site costs. For example, the wall frames pictured on this page were erected in just 2 days, as were the main box section portal frames.

Such a building could not have been constructed with controlled on-site costs without the advanced 3D component modelling with Cadwork and computer-aided manufacture with the Hundegger K2. This is Building Information Modelling (BIM)

This technology enables complex timber structures in large commercial buildings to be assembled quickly and easily on site. This significantly reduces labour costs and uncertainty where fixed prices on labour may not be obtainable.
