SINGAPORE: The Housing and Development Board (HDB) has rolled out the use of artificial intelligence (AI) to enhance worker safety at its construction sites. This AI system will focus on two scenarios which are common causes of worksite accidents, based on data from the Ministry of Manpower, HDB said in a media briefing on Thursday (Sep 12). The system will monitor workers who come within one metre of a non-barricaded edge with a drop of more than two metres and those who are under the path of heavy loads lifted by tower cranes. Currently, construction work sites rely on manual supervision by site supervisors and Workplace, Safety and Health Officers (WSHO) to ensure compliance with safety standards. According to HDB, this is a "resource intensive endeavour", requiring multiple WSHOs and supervisors.
