Within Habitat's building budget
of 13.5 million dollars, a precast
concrete factory was erected on
the site in order to cast the modular
boxes, along with other building components,
such as pedestrian streets, elevator cores,
and access stairs. Simultaneously, additional
pre-fabricated components were manufactured off-site,
such as fibreglass bathroom units and
pre-assembled kitchens. These components
were delivered to the site and installed in
the prefabricated modules, before being hoisted
into place by crane.
Once in place, boxes were
connected to each other by post-tensioning, rods,
cables, and welding. The boxes, pedestrian streets,
and elevator stair towers formed the three structural
elements of the building. They were connected together
to form a continuous, integrated three dimensional
structure, all participating as load-carrying members.
