aeiou228,
Ok,I am convinced on bigger roving area and bigger LAL.
Still cannot find a way to get rid of the pillars if I want to maintain the width, my engineer said in order to maintain the width without the pillars,the beam will be much bigger and that's expensive. He said to get rid of the pillars, the width should be reduce to 6 meter, then the beam can be just a little bit bigger. Will need to study further on how expensive and how much bigger on LAL.
This will be our first BH, need to do it right in as much as possible with our little knowledge on this area.
Thank you very much for your advise.
For me, it is not necessary to maintain multiple sets of 4m x 4m square for open nesting area concept unless you want to create partitioned rooms. Therefore your BH's width can be reduced by 1m and transfer the $ saving to lengthen the building by 2m. It will cost you the same based on area per sq ft. And you have a BH with no pillars !!
7m width no need middle support pillars still can. Ask Engineer Lee about it.
Some shop house BH I'd visited used only the staircase entrance as control room !!

I'm thinking of the control room... one 'petak' would be kinda large. Unless i intend to make it a living quarter as well (which is not advisable).... mulling what aeiou228 said... doesn't need to be that big, and most definitely a waste of nesting area.
hmm... about the slabs... i hear the minimum is 4 inches. Reinforced with BRC + Y12 (or was it Y??). I think one of the forumers mentioned a long time ago... but just to remind, the slabs must be given attention. Also mulling about water proofing the rooftop slab with that tar like material, just in case the asbes roof leaks (it'll be a pain to repair leaks). Since i'm not from a construction background, there might be mistakes here and there.
Judging from the size of your BH, I guess you can have the luxury of bigger control room for storage purposes.
If I can rebuild my BH again, I will build the control room and the staircase outside of BH wall as a small rectangle attachment say 6' x 10' x 3 storey high. Every floor will have individual door access and a big glass window for periodical observation and placing cctv without having to enter the BH. Sound Equipments can be placed underneath the ground floor's staircase.
