Over the past month, steel tie work, steel form work and concrete pouring were completed for the third floor columns in the west wing. At the same time, steel tie work for the roof slabs in the northeast and southeast wing had begun. This was followed by concrete pouring for the roof slabs for both wings and finally removal of the steel form work. As the roof floor of the northeast wing was nearing completion, work had started to construct the four columns on the roof floor to support the elevator shaft. Earlier this month, in the large west wing, steel supports were installed and steel tie work was carried out for the roof beams.
