........
I see a few problems with you allegation:-
a)
According to AHPETC, NEA was coordinating this cleaning. And there must have been previous cleaning of the same hawker center when NEA has always been the coordinating agency, and the hawker association has always been providing the scaffolding, unless AHPETC is lying.
If that is the established and understood SOP then you could only fault AHPETC for not double, triple confirming with the hawker association that it was really going to provide the required scaffolding this time.
b)
AHPETC mentioned it was involved by providing the cleaners, not some "resourceful" contractors. But I could imagine the TC would have considered:-
=> reach Blk538, see no scaffolding on day no.1, quickly contact at least 2 or 3 contractors to come down to give quotation
=> hold off any cleaning on the lower level until the scaffolding is up, cleaning of ceilings and exhaust ducts are done
=> scaffolding maybe setup by end of day no.2
=> cleaning begins...........
Simply, this means the cleaning is already behind schedule by 2 days. No?
c)
AHPETC said no extra cost is mentioned by itself. In fact it could be still thinking and negotiating with NEA / hawker association to provide the scaffolding. So where did that come from?
Somebody stirring conflict?
So unless you have additional or differing information, let's wait to see if NEA or that hawker association will add on, shall we?
