i want to do car porch tiling outside my nipah gate, however realize that the porch reaching to the road is slanting sideways, on the right is higher slope the way to the left front corner. The right cannot lower the ground else water cannot flow to the road. The left cannot make higher else it will be high hill slope for my car to drive in. If the car porch tiling do slope to the left front corner, the tiles might jack up at the one corner. My contractor also scratching head and propose to make the tile smaller.
How to make it a smooth slope?

stopping by in a construction thread.
wanna see how a real house go through planning, design and construction? link is in my sig.

QUOTE(lucifer_666 @ Nov 6 2014, 12:28 AM)
1. is it more economical to build a house with concrete beam or steel beam?
2. how about the cost of building a basement/subterranean level. what factors need to be put into consideration. is it advisable to do so in malaysia, considering our climate, soil condition etc?
3. how about the wall building purposes, is it better to use red bricks, cement bricks or glass-wall? how about its thermal insulation property, as im considering passive cooling design for the house as to lower ac usage.
4. thinking of a 2/3 storey detached house with minimalist styling. thus its spacious and airy with lotsa light coming in, thus the question with the glass-wall...
thanks for entertaining the questions... got lots to learn anyway  sweat.gif

1. depends. concrete beam is cheaper, but in some situation it's just not feasible to erect a concrete beam and a steel beam is a better option.
2. water table. and maybe soil condition. if both is preferable, then it makes much sense to build underground.
3. we're heavily designing (and implementing) passive cooling in our build. windcatcher, wind stack effect, directed airflow, insulated roof, natural ventilation. even considering AAC bricks. maybe you could take some pointers from our build.

QUOTE(lucifer_666 @ Nov 6 2014, 07:19 PM)
thanks for the reply smile.gif
1. how much more expensive is the steel beam compared to concrete beam?
2. 15 times more expensive than brickwall, eh? meaning, a 20m2 of window would costs 15 times more than an ordinary wall bricks, cements, paints etc. included? thinking of large windows actually, but used the term glass wall. yea, its aesthetics though...
3. and i assume the cost is after considering the insulated/low-e glass? or itll be more expensive with that option?
4. as for roofing material, would asphalt roofing be a good choice, considering our hot & rainy climate? worried about the possibility of the asphalt to melt down a bit under intense sunlight and to be compromised by sudden rain. ceramic seems to be tougher, but its also heavier. copper is an unorthodox choice, but might be prohibitively expensive. any opinions?
5. iinm, usually once the land has been cleared and the drainage built, itll be given some time to let the land settled. how long does this usually take?
6. whats a good practice for building cost estimates? excluding the land itself, how should the costs be broken down?
7. and what about the good practice in choosing the contractors to build the house? any advise?

still got 2-3 years maybe before doing anything with the house-building plan, or even longer, depending on the economic condition etc.  sweat.gif meanwhile, i better prepare myself with necessary and relevant knowledge.

therefore, so many questions...  sweat.gif

1. sorry can't help with that. i'm not QS.
2. prices for normal glass windows is around ~RM12 psft over here. including aluminium frame and installation. if i'm not mistaken.
3. cost for dual glazed, and tempered glass also depend on the frame quality. IINM it should be around RM50-70 psft depending on the thickness & type.
4. flat roofs constructed by concrete slabs will need asphalt treatment. not usually recommended for residential as it requires much more maintenance.
5. jkr spec need 1 year is the soil is new, not compacted. existing land after clearing usually don't need as long.
6. depending on area. and who you ask.
7. yeah. don't pick problematic ones. also higher priced doesn't mean better quality.

since this is not my thread, i'll refrain from giving more answer.
i reckon you could also learn quite a lot inside the home renovation and interior design subsection.

thanks for the input bro. and i visited your link. such a great help too! thumbup.gif biggrin.gif

since youre going minimalist as how i intended mine to be, someday (open-floor plan, minimalist), itll be a very good read to know about your progress and updates smile.gif

hopefully your dream-house construction will proceed without any problem! smile.gif

If I build a container house. Stack them up together with external roof do I need to apply any approval local government ?
Kinda blur with the requirements

a habitable building is required to be conform the requirement as stated in bylaw. so far I didn't really come across hence no much idea abt it sweat.gif

this is the 1 I'm frequently refer for.

how accurate is using poundage in estimating structural loading? do engineer use this method for structural design?

poundage is for temporary estimation / general checking only. engineer got their own structural design when come to this. (eg. the area of the steel and area of beam when come to section got certain ratio to comply therefore poundage is relate but is not 100% accurate) and also depend on the loading the poundage figure might deviated a lot.

if i got no time for measurement, can use poundage? based on your experience, normally how much kg/m3 for floor beam for high rise building like condo? 200kg/m3?

200kg seems more than enough for beam. well, u can do sampling measurement. take a beam at ground floor and measure a beam. best is u have the accurate qty, because u have more qty, ur price no longer competitive, ur price less qty, u get the job and suffer loss.

so I understand ur position, possible request to get the rebar qty in contract is "provisional"?
