RC or normal clay roof? if spillover is only the side water, that is ok. But if its the front portion, is the neighbor contractor responsible to add a gutter.

the side water.
it is spilling onto my side board which is timber and it's rotting.
darn!

what is the purpose of putting pvc pipes into the columns?

to hide the gutter, on the floor, the pipe will have a L bend out and connect to a bigger pipe under the floor and flow out to the drain.

from the slab picture, i believe there are no cover allowances for the bottom part of the slab...

Discussed with the contractor already... when his indon workers were laying the slab,he was not there.
Well ... what done is done.
The next one will sure to put on spacer.

My boss lady do not like the design.
Says that it blocked her 1 st floor windows view.
Have to nego with contractor to re-do tomorrow.

remove the conventional roof. Use RC slab. But you need to make sure you have another beam / supporting pillar around 12 to 15'

The major pillar/columm is still there, next to the door.
They are going to set up another 2 new corner pillar/columm at the new corner of the extended wall(Extreme left and right),
then put a new RC beam across joining the 2 new pillar and the existing pillar providing support.

The columns are there for a reason. You may remove stiffeners BUT NOT columns without first propping up the supported beams. It is very dangerous as anything may happen. Would suggest that you get your contractor to prop back the beams without any further delay.
I would not stay under the structure until all the temporary props are properly in place.

Better get a structural Engineer to take a look on your proposed new supporting pillar & Beam.

Basically, you need to have the replacement supports in place before you can remove the existing ones.

The way my contractor build is made the new pillar, wait 2 weeks before knock down the pillar.

Between end to end of the beam i hope the max is no more than 16' or less, my contractor told me better no more than 16' else very dangerous.

If the structural beam has been properly designed for, it can even go up to 20' clear span. No problem.

Tell me about it.

When my contractor remove the plaster of the old house beam and pillar. Dam we were surprise. One of the the pillar was build not tall enough, then latter add on the Concrete, We can see one pillar two difference tone of concrete and the top part was like 1 feet of difference color concrete before the beam is land on.

That could also mean that the 1st concreting of the column was not high enough. Thus a 2nd casting of the column and therefore you see the different in colour. All this is OK provided the column's steel bars are extended into the concrete beam.
However, if the column was stopped short and the gap between the top of the column and the bottom of the beam was patch up with cement mortar/ with bricks, then it is a cause for concern.

Yeah, my contractor told me too, but funny the concrete so easy to peal out. I can use screwdriver and push out the cement and rock.

Anyway, we never want to hack and see the bar, but instead add another pillar in front (below my parking porch), and extend the beam. So now my house center beam is support with 3 pillars. <6feet beam>+<4feet beam>+<16feet beam>+ ("+" represent pillar)

Am not sure what your contractor have done. I am not implying that what he has done is wrong or anything.
Introducing additional supports at the wrong location can be detrimental as the structure could behave differently from it original intention.

e.g. This is a case that I have come across in a house renovation project years back.
Some car porch are designed as a cantilever structure. Meaning that there is no support at the extreme end. (for aesthetic reason) The contractor then added a support as the house owner wanted to add a RC slab over the car porch. The structure collapse but luckily no one was around when it happened.

For safety sake, I really hope your contractor knows what he is doing.

Yes, there is additional on both end my 6' parking porch RC Slab, and one in the center. I told my contractor i need the Beam to support additional load for future 6' skylight temper glass, and minimal weight is about 1 Ton for the beam need to support.

The new center beam, and pillar is additional support to my house center beam, and first floor extension out.
