Hi juz wondering, how do you determine if the column base needed/need not to have wooden support?

From what I understand from my contractor, A columm is basically a concrete formed around a skeleton (woven steel bars). No need wooden support. Wood are used as formers for the concrete only (they form as tempoary outer shell for the not yet hardened concrete to enable the concrete to get its final form).

Do not know of columm base needing wooden support.

Maybe only support as in concrete formers only...

ok thanks, actually, i'm new to renovation, i'm aso planning to do kitchen extension, but my renovator said. footing (kayu bakau) X3 has to be done first. isit necessary? or depending on soil condition?

looks very watery the cementing.....

Fresh liao...

If the soil condition below your footing is soft and not able to take the load from the structure above, then one of the way is to use piling. The type of piling (material) required will depends on the load and also the soil type. The material for piling can be timber, RC, steel, etc.

In most cases, the loads from a house extension are not too heavy that requires piling, unless the soil is very soft or the footing is situated close to a slope, etc. First option is to try enlarging the footing's size instead of using piling as it will be much cheaper the piling. Only when this does not work, then only piling comes in. As piling is more expensive.

Bakau trees are found in mangrove swamps wetlands. These can be use as piles to support light loads. As Bakau trees are found in mangrove swamps, they should only be used in water logged soil. If you try to place Bakau into dry soil, the material will deteriorate in no time; thus defeat it purpose.

From the first pic, I think your SC has damaged one of the Pipe... did you get any Engineer to design your house Structure?

The pipes are from the existing roof pipe waterways outlet.
Going to re-do car porch roof so making a new water pipe outlet.
Going to do the whole house plumbing system.
Is a Engineer required in this circumstances?

I just kind of doubtful with the workmanship....

If your renovation work involves any structures (whether demolition or addition), the local authority, would have required a Structural Engineers' s design before they will give their approval. Go check and refer to your submitting consultant.

Definitely, the construction would not comply to design requirements. No proper beam between columns. Base slab thickness looks too thin. In any case, don't think authority allows extension to the end of the boundary. There must be some setback. However, in Malaysia, nearly everyone extend their kitchen to the end of their boundary.

Your new footing need to connect with existing?

This one follow what the architect drawings (who also happens to be the submitting consultant that apply MPSJ permit) design.
Thus design approved by MPSJ.

They allow back extenion to the max, I of course more than happy, more room liao.
The extension only involves the ground floor. If involves the 1st floor back extension then I understand, there is a limit involved.

Most local authorities allows rear extension up to the boundary with 450mm roof overhang.
Without looking at the actual work, it would not be proper to comment that the construction is not in compliance.
If you take a proper look at some of the earlier photos, you will noticed that the ground beam was constructed below the ground slab. This was so that the beam will not block the doorway (back door)
As to whether the beam was constructed to specification, cannot comment as not much was shown.

Honestly speaking, from the attach photo there is lots of incompliance in terms of "standard practice"..

Whether the beam is built up to the slab or below the slab is nothing to do with the back door.. Is whether the design is Suspended or Non Suspended..

There is lot of non-compliance from the attached photo in both workmanship and design..

Just wonder back extension part, new footing did connect to existing footing or slab or not.

how come they never put a plastic sheet at the floor before the steel mesh and concrete???? they should also put a spacer....

I am not sure what you mean, but if you mean footing as in the existing floor inside the house, the old existing marble floors are totally hacked.

Added on July 25, 2011, 11:20 amaccording to the contractor - usually when the developer build up from empty land they put plastic sheet.
As the base is still there, no need to put plastic sheet in this instance.


spacer - what is this?

for the car porch, do we need to put steel at the bottom of the floor?
