SINGAPORE - A concrete feature on the exterior of a Housing and Development Board (HDB) block collapsed on Sunday (Sept 25) morning, but the authorities say no injuries were reported.

The incident occurred on the fourth floor of Block 201E, Tampines Street 23, around 10.05am.

No Singapore Civil Defence Force vehicles were dispatched, The Straits Times understands. Police arrived on the scene to cordon off the area.

The Tampines Town Council, which recently conducted painting and upgrading works in the precinct, is working to establish the cause of the incident.

"The dislodged feature is a sun breaker. It is non-structural in nature and will not affect the building's structural integrity," the HDB said in a statement, adding that its engineers have inspected the block and found it to be safe.

In a statement on Sunday evening, the Building and Construction Authority (BCA) said that the dislodged concrete sunshade did not affect the structural integrity of the building.

It has directed the town council to carry out a detailed investigation and recommend permanent works to rectify the damage.

The professional engineer engaged by the Tampines Town Council will also inspect nearby HDB blocks with a similar facade.
