Hi all, I have sent your his contact.
My renovation was stuck for a while due to the MCO. Nevertheless, I got a few benefit from the architect drawings, e.g.
Set up the unit prices for each type of works. It would be easier to do apple to apple comparison when selecting contractors as well as pricing for variation order. I got the unit prices for
- Demolition cost per sqft. The price covers hacking and removal of the debris.
- RC slab per sqft for 6" thickness. The price include both 16mm steel bars, cements, etc.
- Unit price RC column for 3.6m heights per engineer drawing.
- Unit price RC 600mm or 450mm beam/ground beam.
- Waterproofing per sqft.
- Manholes per unit.
- Labour cost for the tiling (based on the size of the tile and by Sqft)
- Per sqft for metal roof.
For plumber/sewage/bath-room, most of the contractor quoted by rooms.
The architect drawings can help you to prepare your own Bill-of-materials, it can also help to gather the requirements e.g. door schedules and door frames.
Another lession I learn: negotitate the fees as well as the fees for resubmissions. I have two resubmission.
Lastly, if you are renovating very old semi d or corner house, I personally think it is best to knock down completely and rebuild. I made one mistake by expanding. Later on, part by part, I totally demolish the whole house. That cost me about extra 10 - 20% in total cost. It also drag longer.
