面对建筑生产力下降，新加坡建屋发展局上年起与其他机构，合作研发3D混凝土打印技术。当局上周四（12日）宣布，将首次以东南亚最大的3D混凝土打印机，用于部分房屋项目以提高效率，并研究以该技术完成组屋工程的可能性。

该部价值约90万新元（约270万令吉）的打印机，上月测试时只耗时13小时，就成功打印出一个长3.6米、宽3米、宽2.75米的房间，算上人手设置钢筋等时间，一间房仅需6天完工。当局将在部分即将落成的组屋项目，首次应用打印机建造景观设施。

据悉，传统建屋方法单计制作昂贵的混凝土模具已需2个月，但新技术则不需制模，更可作更多复杂设计，既减低对劳动力依赖，亦为未来建筑提供更广阔可能性。新加坡国家发展部长黄循财承认，技术目前成本较传统建屋方法高，但有信心未来能全面应用。

除了崭新的建屋方法，当局正研采用无人机技术检查建筑物外墙，取代费时的人手游绳，目前正探讨改进无人机信号易受干扰问题。另外，当局本月下旬拟试用人工智能监测系统，透过自动检测高风险情况提高工地安全，试验将于明年第4季结束，冀能扩展应用在其他方面。
