The this photo from September 1995, progress can be seen in the southern part of the building. The reinforced concrete core, which was constructed in stepped sections using a patented shuttering system, functioned efficiently after a three-month period of continual work. Some of the steel trusses for the floor structure of the Level 2 Exhibition Hall, including the first two pairs of supporting columns, was installed. To reduce construction costs, the floor slab of Level 1 Exhibition Hall was constructed of reinforced concrete (rather than structural steel) as there was no need to provide a large-span design for the ground floor area.
