The story
The Public Works and Convicts Department was formed in 1833 after George Drumgoole Coleman became the first superintendent. The department was formally established as the Public Works Department of Singapore (PWD) in 1946.
Under Temasek Holdings, it was incorporated in 1999 and renamed to PWD Corporation before again being renamed to CPG Corporation in 2002. A year later, it became part of the Downer EDI Group.
In 2012, the ownership of the CPG Corporation group of companies was transferred from Downer EDI, Australia, to China Architecture Design and Research Group.
