The contractor cut light wells in the centres of the buildings from the roof down, and used diamond-impregnated arix saw-blades and core drill bits to cut out the concrete slabs inside the beams, preserving the integrity of the building’s structure. The final demolition works have been completed, with construction work due to start in June.
Precast façades with small windows were attached to the exterior of the offices, but this design severely restricted external light from penetrating the building. Q&A is removing alternating precast façades to install bay windows for outward facing flats, while the light wells will provide light, ventilation and services to the inner apartments.
The precast concrete façades are attached with steel reinforcing pegs, and are cemented in place. Each weighs about half a ton. Q&A attached the façade to a block-and-tackle bolted to the floor and then drilled through the reinforcing bars using a Shibuya diamond- tipped coring machine. The façade was then safely pulled into the building and demolished.
“The aluminium frames in the demolished blocks were salvaged and stored for future maintenance work on the remaining windows,” he adds.
The diamond-impregnated arix saw blade and the diamond-segmented coring machine were supplied by diamond cutting tool manu-facturer Diamond Products. The company helped the contractor with the innovation and manufacture of the diamond tools and advised on tool specifications to perform the demolition within scope and deadline.
The ground floors of the buildings will provide space for commercial shops and services, adds Dippenaar.
Further, the development takes place on the same street block as other Afhco developments, including corporate offices, a supermarket and further housing develop- ments that will convert the offices on the corner of End and Rocky streets into apartments.
The office blocks had been used by illegal occupiers for a number of years, but inadequate sanitation and ventilation contributed to squalid conditions. Q&A’s work ended in May, but the final buildings will be ready for occupation during 2013, he says.
“Houghton, the central business district and the highway are each five minutes away,” says Dippenaar.
Further, the buildings are situated about two blocks away from the Doornfontein train station, and are on the routes of taxis using the Bree Street taxi rank.
