The formula is
price/units x units = final price.

What is the point of your post anyways?

TS, mind to share it here openly?

Yalor..just share openly la..I thought this is for sharing...

Didn't know there's special formula for calculating renovation works. Is there?

Many things are worked out based on cost per unit area (sq ft/ sq m) or foot run eg. tiles, ceiling,
For others like concrete works, painting, it's cost of material + labour.
Smaller items, things that are hard to quantify, are based on lump sum.
The main contractor add in a profit (say 10-15%) over their cost or the cost from their sub-contractor.

my previous post under topic 'good contractor'....

...i m new in lowyat....silap sikit..sorry...

about renovation..i had experienced for my house renovation...i had just completed my house renovation..this month.....big renovation...it took me one year to complete my house (slow and steady) after kena tipu...i do it from A to Z (until kitchen cabinet)...

the story like this...first quotation by my contractor was about RM75K (started 23/11/2010) but after took my money about RM60K (workmanship just 50% completed)..then tak boleh siap....2-3 minggu sekali dtg tgk project....i myselft yg monitor the project.....at last i completed my house renovation myself (i became my own contractor...smile.gif)...to be frank..i can claim myself contractor smile.gif...the money i lost i would considered a good lesson for me (bukan rezeki)...about the selok belok susah senang to complete my house...i do studied and research (from internet,tanya member, tanya contractor lain etc) quite a lot about renovation....now i have completed list off all contact person for renovation.

For renovation, if you want satisfaction (and budget pun cukup2 ....unless you are orang kaya2) , do not hire lump sum to one contractor but have a list of persons in specializing t in one thing example, tiling one specialist, ceiling another specialist..this is what i do...

i aslo tau mane mau cari barang contoh..kedai pintu mane bagus, kedai pintu toilet mane bagus..kedai jual sink , org wiring, org tile,air cond man.. dll....

my previsous contractor is Zakaria from Puchong HP 0123537084..soft spoken, big guy...give cheap quotation...be carefull with him..

if you all want my advised and contact person to do things for renovation...... do PM me...one more thing if want to do renovation, you must spare your own time to quality control or monitoring...

Added on February 17, 2012, 8:29 amFIRST LESSON to know....many thing i can share about construction...if you want to make renovation..at least you must know basis things..else your contrator will cheat you.......Fist lesson ....there are 2 types of steel iron for construction..i believe 99% do not know this..only contractor know...

First type is BS type of steel iron for concrete...BS means British Standard. Second is CQ type. If you go to hardware shop selling construction material.. normally they will ask..BS or CQ...if you want to know what is CQ stand for...do ask me..smile.gif...

1.the differences between BS and CQ is the quality and percentage of pure iron inside...the BS steel iron is so hard..compare to CQ (CQ steel iron is a bit 'lembik' and BS steel iron is bigger size...if you want your house stronger and lasting and do not want to crack beam later after a few years....then.....insisted your contractor to use BS steel iron...i m sure they will surprise when you mention BS and CQ...the price of BS steel is higher about RM4-RM5 per pieces. That why contractor do not want to use BS..they want to lower the price with lower quality of steel.

2. I can know by looking at the steel whether it is BS or CQ and what size the steel iron....there are many size of steel iron the lowest and smallest is size 8. There are sizes 8,10,12,16..etc....Make sure for beam and foundation..at least use size 12...do not used size 10...some contractor used size 10...later many years your house will crack..

i share to you all many things that i learn...later....if i m free...

secondly...for foundation of pillar...make sure the hole they dig at spec level...for single storey house...min hole size for pillar foundation is size 3X3 feets...deep about min 3 feets...if your house is use to be swap area like puchong etc...ensure the 'tanam' 'kayu bakau' 5 batang...that why you see some house after few years ...crack here and there...the contractor want to safe money...for double stroey house..the foundation size is at least 5X5 feets...deep about 5 feets...for double storey house..ensure 'tanam kayu bakau'....





if some body want to know mane kedai lampu dan fan murah...go to puchong kedai corner sebelah tesco..nama kedai is TEN TEN...for electrical shop yg murah is at Bandar baru sg buloh..cheaper eg..i bought new freege and air cond.....RM 200 cheaper..



Added on February 17, 2012, 2:57 pmjust to share...actually most contractor use formula to calculate the estimation of you renovation..else..how can they can give quotation between 2,3 days...if somebody want to know the formula..do PM me..

TQ..


after the selection of the steel iron, observe also for the sand type they use...the best sand for renovation is from 'mine/lombong'..usually the mine sand is white in color....the.....second is from river..or we call pasir sungai....normally river sand in yellowish or redish in color.....for pasir sungai or river sand..make sure that the river sand is 'wash' type...else....there is mud inside the sand..causing your concrete not strong enough....

about the price to calculate the price is simple..so that when you want to make renovation..you can know the range price....afraid to share openly...afraid there is contractor here...cannot cari makan...what techmc mention is right....but actually/generally contractor has one figure for calculation for all the works.....when quote the initial price..they dont break the price....they give lump sum price...do PM if you want to know..

No, river sand is better and more expensive than mining sand as it has less impurities.
Most contractors use mining sand.
Choice of contractor is most important, normal housebuyers would not know much about contruction.
There are 1001 things the contractors can cut cost on.

This post has been edited by tehtmc: Feb 22 2012, 11:22 AM

my experience..for river sand is good for plastering...but make sure 'washed' river sand...else..you know when mud mixed with cement...

tehtmc..your r right about contractor...


for my house ..i personal buy the all building materials....from A to Z...from the biggest and small small things....even i also learn from the workers..how to do this and thats...i also learn how to 'ikat' the iron concrete steel,plastering,skiming etc.. ..i also design my own plumbing start from meter to water tank and...completely....even for kitchen sink plumbing and dispose pipe..i did myself...also....i also design my sewerage system from toilet.kitchen to indah water... .next time when i want to do reno..i just find the workers only....i be my own contractor....

Depends on what your 'hourly rate' is....it might be cheaper to get contractor to 'pau' all these things.
You time is better spend doing what you do best!

How many people would be so free and have the time to be oversee the renovation fulltime? And not everyone can be a jack-of-all-trades.

The thing about buying your own materials is that you have to monitor and make sure there is no wastage. Workers would not bother to save material for you. If your order is not enough, you have to re-order again - very lecer and have to deal with so many suppliers.
If you order too much, it would be wasted.

This post has been edited by tehtmc: Feb 22 2012, 12:42 PM

for me its better for me to spent my my time rather than giving all to the 'so call contractor'...about buying materials...ok then....i give special tips how to handle this to you and forumer..on big material such as sand,cement,steell etc........usually hardware shop had special account..... i personally open account with the hardware shop under my own name..i put money or deposit say about RM2-3K into the account...then when my worker shortage of material..i just call the shop to deliver and deduct from my account..then i refill my account........about waste material...what i did is, i ask my worker..how many they want and i estimated myself...usually i order a bit lesser from what they request...tak cukup order lagi.....


i share one more thing..my house using GI steel metal trust..for roof..i not using kayu..even that lousy 'Zakaria' do not know how to use it...i share some photo... i hv many photos from foundation....


i try to post photo..how to post photo..i add attachment but not keluar pic..

TS, the rebar diameter can goes down to 6mm.
And the kayu bakau is prohibited to use as pile/foundation by the local council long time ago.

At my area no problem.still using kayu bakau...

Your area is where?

the most difficult thing using GI trust is to lift from ground to upper beam...if already pro can install the GI on the beam itself.

another tip..for roof tile..if want to use biasa2 punya..go for brand such as 'Monier'...around RM 2 per piece...

one more thing...for sewarage..please use PVC pipe for under ground color oren Sirim approved as pic below..do not use white PVC...white PVC for rain water can...

one more advise..for sewarage..every corner should have one main hole..this is to avoid clogging...and also the corner must use clay corner..as pic..

Hi tomjason,

First of all, i would like to say thank you to you for sharing your experience with us.
I feel sorry for what happened to your money. Hope you will catch that liar in the future.
Can you please also pm me about the renovation calculation?
I am planning to make a 'tembok pagar' for my car porch, but only on one side since my neighbor already done it for my side
I am thinking to buy the material myself and just call the worker to make the 'tembok pagar' but don't know how much is their workmanship cost.
I've asked 2 contractors but they quote around rm1.2k++ inclusive materials, which i think quite expensive.
Do you have any contact for worker to do the 'tembok pagar' for me?

Your help is really appreciated.

Thank you for all the help.

I will wait for your pm.

Anyway, my location is at Puchong.

I am going to extend the extra 5 ft backyard of my house, and a few quotations were given to me and they each cost at least RM8.8k and above - i forgot to ask what kind of bricks they use for the extension, but will take note of using red bricks, since it's only 5 ft (dun mind paying the extra for better quality stuff).

I am very blur with all these renovation stuff and i don't wanna get cheated for whatever I've paid

thank you very much ...

Added on March 28, 2012, 8:23 amtoday tips: i would like to share today cost for indon worker. Indon worker normally call daily work as 'Kong'. So for today cost, one Kong abour RM70-RM80 per Kong per day. For supervisor rate, the Kong rate is RM90-RM100 per day.

Normall working hours is 8 am to 5 pm. Normally, contractor give overtime if working after 5 pm.

Therefore, reno cost nowadays is expensive, compare to 5 years ago, the Kong rate is only RM50.

PMed noien,ozone9,wlm already.



today tips:

please ensure that the space between roof trust frame is not more than 4 fts, this to ensure that the roof trust is strong enough to support your heavy roof tile.






pic below is my neighbour contractor using small wood for truss, i suppose 2x4 inches. If want better, use 3x5 inches. The disadvantage of wood is termite and wood after years..it will bend.

---

Added on March 29, 2012, 11:08 amAnother tip:

to avoid any crack after plaster, please wet your wall before apply the cement for plaster. The brick has the strong ability to absorb water, thereofore if you do not wet the brick, it will absorb the water from your plaster cement, cause the your cement plaster premature dry , not normal dry.

These also apply when, cement the 'rabung' for roof. Please cement your 'rabung' not during high sun eg in noon.

can PM me the calculation as well?
TQ

What kind of shape is the metal roof trust frame? I beam, c shape etc.

Are there strong enough to walk on it at least?

Do you need to ground the frame?

Do this frame stand against the rust?

How is the cost compare to wood frame?

PMed Kinkong81.


Let me elaborate about this steel trust (kekuda). The steel trust is new to malaysia and to most contractors, not many contractor know how to install these steel trust. The difficulty in technique to assemble and joint between steel is the main reason, but if already expert or experience no problem. To the beginner, to install the steel they hv to assemble on the ground and lifted to the upper beam, lifted the frame is difficult job but with experience, they can install on the upper beam itself. The steel trust C type, to make is stronger, they must clamp together.









Are there strong enough to walk on it at least?

Yes, they are very very strong..when they are clamp together and joint compared to wood. As picture above. They do not bend over time as compared to wood, for wood you will see that your roof will 'melengkung or melendut' over time.

Do you need to ground the frame?
Certainly. You have ground it to upper beam.

Do this frame stand against the rust?
Yes, they are Galvanized to protect from rust

How is the cost compare to wood frame?
The overall cost is abit higher compared to wood, but it is one time investment, long lasting forever compared to wood.
The cost of per piece is not expensive around RM32 compared to wood but they must clamp together consisted of 2,3 piece to become one.
They are joint together using GI screw and if you were to buy loose, the screw cost RM0.08, but if per boxes more cheaper. Every joint between steel at least minimum 3 screw else afraid not strong enough.
