A building contractor was fined $5,000 for not following proper procedures for works done at a Build-To-Order (BTO) project in Punggol, after residents raised the alarm about the use of cardboard-like materials in the finishing work on a wall.

The contractor, which was not named, was also given 50 demerit points for the incident at Waterway Ridges in 2016, the Housing Board told The Straits Times last week.
