concrete floor BRC.... size or brc ? A6, A8 ? Cq spec or BS spec
concrete floor brc - quotation include damp proof membrane? before concreting?
carporch roof slab- waterproofing?
plaster ceiling- type ? plaster of paris or gypsum?
for outdoor ceiling or toilets /laundry area- proposed gypsum moisture resistance-example USG BORAL WETSTOP MOISTURE RESISTANT.
Staircase- ask the contractor to confirm numbers or step - width and height of each step.. do not exceed the maximum requirements under UBBL...
staircase construction is tricky - need to properly design and confirm tread and riser.... i have seen staircase construction that are just nonsense.
Tripping Hazards and Safety Concerns: Incorrect riser heights can lead to tripping hazards and safety concerns, especially for individuals with limited mobility (old folks)
This are some input when i glance through your quotation.

You highlight a good point about waterproofing. I did my renovation two years ago. My architect and engineer did specify a layer of plastic for waterproofing. However, the contractor did not follow the instruction before casting the concrete floor. Less than six months after the completion of the tiles, all my grout lines changed color. My tile installer did the grout lines and less than six months, the grout lines changed color again! Root cause is due to the slop at the back of my house. concrete floor BRC.... size or brc ?

I noted the quotation did not specify the thickness of the concrete floor and did not specify whether it is A6 or A8, as you highlighted.
For me, after one renovation, I will not accept any contractors with lump sum pricing. I would rather pick those quoted the detailed technical and unit prices. A bit expensive is okay. It is much better than any rework.
