Took only 13 weeks to stack the 295-foot building
This week Tide Construction installed the last module at Apex House, a dormitory tower near Wembley Station in North London. The 25-story student residential building is a honeycomb of 679 separate modules, and the tower will be the largest in Europe and is expected to be ready for students by September.
The 12-ton modules are made by Vision Modular Systems in Bedford, England and resemble shipping containers. However, each one was delivered fully complete with a kitchen and bathroom, lights, switches, socket outlets, and internal finishes.
The building frame has a reinforced concrete core, concrete foundations, and a series of concrete columns at ground level to support a transfer slab on level two. The transfer slab provides vertical support for all the modules above, which are stacked one on top of the other. The modules are lifted by a tower crane and plugged into position in 10 minutes. Up to 11 units can be installed per day, cutting months off the construction time for a conventional steel and concrete building.
The modules are welded together on site to form a rigid honeycomb structure. The most complicated weld junctions are at the point where four modules meet on an external face. Supervising engineers photograph each weld detail to ensure quality control.
