Update on Dec. 8, 2020: Nex has also released a statement on the investigation.

You can read it here: 

"In light of the incident on 30 August 2020 where an Air-Conditioning & Mechanical Ventilation (ACMV) duct detached from the ceiling of Shaw Theatres within our mall, we have worked closely with the Building and Construction Authority (BCA) and the appointed Professional Engineer (PE) to carry out a detailed investigation of the incident, with recommended rectification works to be taken. BCA has reviewed the PE investigation report and also completed their own investigation with similar findings.  

NEX will continue to support and work closely with our tenant, Shaw Theatres, throughout the course of rectifications for the planned reopening of their premises in 2021. We remain committed to prioritising and ensuring the safety of our shoppers and tenants at all times."

The Building and Construction Authority (BCA) has released the findings on the ventilation duct that fell at Shaw Theatres, Nex.

The incident, which occurred on Aug. 30, saw the duct come crashing down during a screening of "Tenet", injuring two patrons.

According to the Professional Engineer appointed by the mall, the chain of events had started due to unforeseen excessive condensation.

This led to a significant amount of water accumulating in the layer of acoustic material surrounding the Air-Conditioning & Mechanical Ventilation (ACMV) dropper duct.

Over a sustained period, the weight of the water overloaded the brackets that were supporting the ACMV dropper duct, causing the brackets to give way.

BCA added that the engineer's findings tallied with their own.

Other cinema owners in Singapore have been instructed to conduct checks on their ACMV systems and ducts, and no similar cause for concern was observed.
