Property developers should pay attention to workplace safety on construction sites as building activity levels remain elevated, a top industry official said on Friday.

"As developers, we should support our contractors in showing duty of care for the health, safety and welfare" of the around 300,000 migrant workers in the industry, said Mr Chia Boon Kuah, president of the Real Estate Developers' Association of Singapore (Redas).

"This enhances productivity, which in the long run, translates into business benefits for all."

Developers and contractors should therefore "up the ante on workplace safety training and communication" and "recognise the contributions these workers make to our country", said Mr Chia, who is also group president and chief executive of developer Guocoland.

He said Redas would hold a forum to identify and discuss common causes behind construction workplace accidents, challenges to risk reduction and best practices.

Mr Chia was speaking at a Redas lunch at W Singapore in Sentosa, where education minister Heng Swee Keat was guest of honour. Mr Heng did not give a speech.

Mr Chia also said that the property market has "begun to show signs of decelerating on the heels of concerted efforts by the Government to manage the housing supply and curb speculative buying".

However, he stopped short of calling for tweaks to the Government's cooling measures, saying instead that the measures "are acknowledged as a long-term necessity to ensure better outcomes for Singaporeans and a healthy real estate market".

Redas said on Thursday that Mr Chia had been unanimously re-elected as its president.
