The Building and Construction Authority (BCA) has allowed Jem Shopping Mall to re-open the affected area where the false ceiling had collapsed last month, it said in a statement on Tuesday.
The false ceiling had earlier collapsed due an overload of the ceiling support system following the build-up of water from a burst water pipe.
The BCA said a mechanical professional engineer engaged by the building owner had inspected the pipework system and certified that it is safe for operational use.
A civil professional engineer had also investigated the cause of the incident as well as the false ceiling systems in the other parts of the mall, and confirmed that the design of the ceiling systems is sound.
The BCA and PUB had also conducted inspections at the affected area of the mall and were satisfied that rectification works have been completed.
The mall's developer Lend Lease announced on Monday that Jem would re-open on Wednesday.
