AAPAC DESIGNBUILD designed and built this single level control office and staff facilities building for State Railway Authority.  The project involved demolition of an old timber building which was attacked by termites and was with asbestos cement roof.  Because of the termite problem, the new building was required to be built with steel structure completely.   AAPAC DESIGNBUILD used a light gauge steel framing system from BHP.  The whole building structure was prefabricated off site.  The erection of the structure adjacent to rail tracks was speedy.  The construction of the building was of concrete slab on ground, brick veneer walls and corrugated colorbond steel roof cladding.  Windows were double glazed with special performance tinted glass.
