Hi-tech savings go to waste

Amid increasing public concern about the adverse impact of high-rise buildings, two major developers have spent extra money voluntarily on advanced technology to reduce construction waste dramatically and enhance energy efficiency.
Swire Properties says it is the first developer to use three-dimensional design software in the design and construction of its 70-storey grade-A office development, One Island East, in Quarry Bay at an additional investment of HK$14 million. It also spent another HK$10 million to reduce construction waste.
Sun Hung Kai Properties, owner of what will be Hong Kong's tallest building, the 118-storey International Commerce Centre, says it has invested "tens of millions of dollars" more to meet growing demand for sustainable technology in construction.
Stephen Fong, a general manager of Swire Properties, said 20 to 30 per cent of construction waste came from new construction. By adopting 3D design software, he said the company was able to produce accurate estimates of materials needed, thus allowing it to "design out waste".
He cited the HK$2.35 billion Island East One as an example, saying Swire had saved an estimated HK$50 million in this project alone. "We will be applying this 3D technology to our other projects in future," he said.
Mr Fong said 99 per cent of demolition waste from the One Island East site, including 2,840 tonnes of steel,
57,125 tonnes of concrete and bricks and 740 tonnes of other inert materials, was reused and recycled.
Kenneth Mo, a project director at SHKP unit Sanfield Building Contractors, said about 4,200 tonnes of waste concrete from the ICC site was sent to the government depot for recycling when the cofferdam was removed.
"As the ICC site is surrounded by residential buildings, we have to exercise extreme caution to reduce noise, dust and air pollution. So far, SHKP has not received a single complaint about the construction work," said Mr Mo, who also involved in developing the group's International Finance Centre Two, at Hong Kong Station.
Sitt Nam-hoi, a project director at SHKP subsidiary Harbour Vantage Management, said the group also built a six-metre temporary platform linked to the highway to move thousands of tonnes of steel and concrete directly to the site rather than passing through the podium in a bid to reduce disturbance to residents.
