Piling requirement for serangoon gardens houses

[imzz 0]

Dear all,

I bought a landed property in serangoon garden area and I intend to rebuild it.

Anyone knows what kind of piling is required in that area (Brockhampton, Braemar, Blandford area) and what would be the piling cost for land 2800sqft? I would like to know so I can estimate the cost of construction as I have not done the soil test.

 

Thanks in advance.

hi,  your probably need an engineer to advise you the type and the piling contractor to advise the cost.

before knowing what's needed,  they will need to know what kind of structure and how many storeys you are building to determine the load and .

I guess cheapest pile will be Reinforced Concrete (RC) pile if your site permit.

I just did 8 micro piles (average 16m depth) for an extension, just for 4 new columns to carry a 2 storey structure. The piling cost close to $19K. excluding engineer fee, RTO, and soil investigation.

have you gotten a builder or architect to design your house? the house design would play a major part on determining the piling needed.

Hi imzz

I just brought a landed at Brockhampton Drive last month. I am in the process of getting started.  I had the topographical survey done.  You can engage the surveyor yourself or through your architect consultant, or design & build contractor. The price should be in the region of $13xx. I am in the process of searching for an soil & foundation specialist to do a soil test. This should cost about $25xx-$28xx. The soil results will take about a few days from start of drilling.  As i know, if your neighbours is within 50-100m who is also doing an rebuild, then you can offer to pay and then share the soil test results, thus saving a bit of money, benefit both parties.

You will also need all the structural plans from BCA. If you have not completed your sales (8 weeks from exercise of OTP), then you will need the owner to help you buy the plans, or have his authorization for you or your architect consultant to buy the plans.  Search for plans in BCA website is $32 and the plans will be available for download within 5 working days at a cost of $25.

You may also want to buy from PUB the SIP(Sewage Infomation Plan), DIP(Drainage Interpretation Plan) and WSP(Water Service Plan). It's good to know where your unit's sewage line runs relative to your landed lot, as anything that is close to your new buildup structural wall will need RC(Reinforcement Contrete) trench protection. My place is only 1 meter depth. So expect the RC works to cost about $15k-20k. The deeper the sewage line, the more expensive its going to get.  Getting a first look at the SIP will get you mentally prepared for the extra cost involved. All the PUB plans you can buy yourself and don't need existing owner's authorisation before pirchase online.

You may also want to purchase from LTA, the RLP(Road Line Plan)

All the above you can ask the consultant to buy on your behalf if you don't want the hassle.

There is lots more submissions and hence cost involved for the various government bodies and you must be mentally prepared for the payment required.

If you need to discuss, feel free to PM to discuss. But i must say everyday I am still learning and discovering new things on the reubild process.

if you are going to tear down the existing house, don't really need to buy the structural plans from BCA. unless you're doing reconstruction or A&A then need the existing plans.

for the various plans from the authorities, the contents may not be able to be understood by laymen so still need consultants to decipher and do the necessary action.

RLP is purchased from SLA, not LTA. submission of changes would be to LTA

just to add on, the cadastral plan is now available for free download from SLA website by the owner of the house. this CP is needed by the topo surveyor. can save several tens of dollars by getting the existing owner to download if it's not too much of a hassle.

Hi AWS,

Thanks for the useful info  I have bought the SIP and thankfully no sewer line or man hole within my vicinity. Wow, didn't know I need to buy so many plans. I have yet to engage architect so I guess I will get them after I firm up on my selection.

I have PM you, please check your inbox

 

Thanks

[cymon 6]

Imzz, leave all the plans to your architect, he will get all for you.

lucky you that the sewer is not in your back yard. I have one running at almost 3m deep. don't know how much it's going to cost me to built the RC trench for that.

buying plans is cheap. the submissions for approval are going to cost quite a bit. one year ago, URA raised the submission fees for new erection from 3K to 6K.

as what cymon had said, just appoint an architect and get them to settle all the paperwork for you.

Hi snooze, yeah very lucky for me. One good architect advise me to buy SIP plan during option period and for me, if there's a manhole and sewer, I may choose to give up the option fee.

Having a sewer is not the end of the world. Just need to spend some $ to built something that we will never see. Of cos if the land is big enough, one can always choose to build up to 1m away from the sewer line and have a bigger open area.
