LOCAL PROJECT
Installation of the
manufactured components
of the primary structure of
the Hub.
The structure strength tests that were performed on site.
THE INSTALLATION PROCESS OF THE HUB
The Hub (also known as the dining hall) was our first attempt in the
timber structure system on the campus. We collaborated with local
timber suppliers and engineers, exploring the type of timber we would
use, taking into account the structural integrity we needed but still
satisfying aesthetical proportions.
Once we had our main structural material, we deconstructed the
building into smaller systems, dividing them into; primary structure
(main), secondary structure (roof and façade structure) and tertiary
structures (furniture and joinery elements).
We focused on designing the systems so that elements could be
broken down into smaller, more manageable elements. This opened
up new alleys for the building to be built by a smaller network of local
suppliers and artisans. Portals were broken down into small ‘puzzle
pieces’ that interlocked with one another to form a complete portal.
Once our design was finalised, we proceeded to building a prototype
for testing. Testing was done in a controlled environment at the
University of Pretoria, South Africa, with the presence of the engineers
and other consultants. We coupled a hydraulic jack to the ends of each
portal edge and tensioned them towards each other to break point.
