Question 1

The works for the Construction of Punggol Mall were completed. The Superintending Officer ("SO") issued a Substantial Completion Certificate. Thereafter, there was an inspection by the Authorities prior to issue of the Temporary Occupation Permit ("TOP"). The Authorities requested for handrails to staircases for safe use of the staircases.
