BABIKING! won't collapse unless u use it for other purpose. example, that is residential house, but u use it as warehouse and store and stacking up a lot of heavy stuff, will collapse 1. their original design intent is meant for residential hence the loading is as per the residential loading. if u want to know the exact loading u have to go and refer to BS5950 manual reference. but then best to get engineer to design if u wanna modify that house

NancyDrewWhite,always use 195/sqft for budgeting.

depend how big u want la. assume 900 - 1000 sqft per storey. standard......

depend what are the wall u want. gymsum board, brickwall, etc. gymsum board is pretty cheap nowadays. since ur qty is small, should be within 2.5k.

oic, about RM570 per sqft. seems like a 2nd tier property in klang valley so can't be fussy as if it's 1st tier quality la

just check about the functionality of those thing ok already. ironmongery is work, the key is correct, the qty of power points is as per agreement, check the wall facing outside 1 whether it's humid to ensure no water seeping through especially windows edge, check the toilet floor by pour a lot of water on the floor to see if the water will flow to the floor trap. sometimes the floor tile they didn't make it a fall, to let the water flow to floor trap, check the floor/wall tile if it already broken as sometimes after completed the work, the other trade by damage it. check timber floor also if u have that as timber floor is fragile especially contact v water. it will bulging when contact with water.

basically is like that. if first tier, there were a lot of thing have to taken care of

I c. Mind to let me know ur friend property price and the total build up area? different tier need to have different measure when come to inspect the house......

depend on one DatoSeriJohnnyWalker. a good QS usually will not work as QS la. more on management. QS oversee a lot of thing. after all, construction is about money. everything related to money.

starting is like that 1 la DatoSeriJohnnyWalker. need to gai a bit 1. too many took up QS course. in TAR college, course with most student is Accouting, second is QS.

DatoSeriJohnnyWalker, because u didn't ask for more. if u capable, a lot of people willing to hire u 1. perhaps ur employer willing to keep u from jumping ship by counter offer if u can make money for company. plus now shortage of manpower, can demand even more for QS I think. after all, QS is directly dealing with figure, hence ur salary will be higher as the figure is always the thing ur boss wanted to know. ur boss will very likely always in touch v u.

靓女 phoon phoon ,*container house seems like a trend now to be honest I have no idea what are the jurisdiction out there whether container to be undergo the same process like building a house.

Printing U.S Dollar Dollar Dollar

1)
best developer? I think buy property see ur budget since the property price is very much related to its location. in my opinion, those developer that doesn't squeeze the contractor to the max is the best 1. as the contractor get what he want and he build what the developer want. if the developer squeeze all the single cents from the contractor and contractor have no choice but to reduce the quality to comply to the cost. but since u asked, in my opinion the good developer are Selangor Dredging, Symphony Life, UM Land.

2)
Engineer is consulting engineer where they design the building to suit to requirement of architecture and infrastructure of building.

3)
safety net.

UraniumKing68, tower crane will climb itself as the building progress reach higher level by adding the mast. after complete, it will lower down itself also by dissemble the mast part by part as it lowering down. in here, most common tower crane we used is hammerhead and luffing crane.

babiking......
1)
u have to justify the programme first. example I demonstrate u the original baseline and revised baseline after 5 month of Extension of Time granted. base on the chart, u entitle 5 months and time, and ur LE have to base on the affected loss and expenses that direct related to the EOT that granted. Example, u granted 5 months EOT, however tower crane just require extra 3 months only and hence u entitle to claim 3 months renting cost of tower crane. however because ur project team still run until the end, so u entitle 5 months wages for ur project team. hence it's not everything automatically get 5 months.

depend on agreement, some contract impose a clause whereby on when come to loss and expense claim, u need to show the actual record (those actual receipt to show that u really spent this amount)

2)
what claim u mean? I don't get u.

3)
L&E is definitely entitle. however as I mention early, this is sensitive issue and client never like this. even contract prohibit u from claiming L&E, some contract impose the clause whereby loss and expense is not allow, however when come to construction work, those changes instructed by client is a variation and in some form, varying the original contract also is a "breach of contract" and remedy automatically come in which is in the form of L&E. not easy thing as a lot of justification require if u want to claim that much.

good question.
YoungTycoonWILL

loss and expenses (LE) is a sensitive issue. will offend client no doubt ......

in order to claim loss and expenses, u have to demonstrate ur entitlement of EOT. to do that u need to have the original baseline (original master programme). then u have to revise the programme by incorporate ur entitlement of EOT inside. by do that ur baseline become baseline 2 (example). then u have to justify ur expenses but putting in the expenses into that period.

example:
1. original rent 5 month of tower crane, now 7 months, u get 2 months.
2. original u pay wages to ur stuff 7 months, now 5 months

bear in mind not all is straight away stuff.

there are few dalays,
culpable delay - contractor fault and therefore not entitle for LE nor EOT
concurrent delay - both contractor and employer contribute to the delay, hence EOT entitle LE not entitle
non culpable delay - employer/architect fault and contractor entitle both EOT and LE

Hi, stockjobber ! Ageson is ongoing sembang with CCCC. Wait for Good news! 90% confirm GET IT!

BABIKING,

The compressive strength for steel is too high. That is why we never even measured their strength. I bet the compressive machine will fail first if you try to compress a steel plate or cube. The reason we add rebar into concrete beams is to reinforce them. Hence the reason why we called them reinforced concrete. The concrete here is the main character and the rebar is just the support. We also never measure the yield strength of the concrete because it will fail almost immediately when pulled (Very low tensile strength) and that is the reason why we add rebars into concrete. For beams, when subjected to dead loads and live loads, it will bend downwards. However, the concrete's strength is from compression. If bending, then it will crack and thus the reason why we add rebars. To enhance the tensile strength of the concrete.

Furthermore, you need to check on which load combinations that your beam failed. During uplift or normal combinations? This is because adding rebars for top part of beam does not help much if the beam is facing downwards force. Furthermore it will only congest the top part of the beam and makes it harder for the concerto and probably end up with a beam full of honeycombs.

However, back to rebars, you can eliminate the need for rebars in your concrete products IF your concrete has enough ductility. One of the latest products are Ultra high performance ductile concrete (UHPDC). Recently went to their seminar and was very impressed by this technology. They manage to make their concrete ductile and hence eliminating the needs for any rebar. Furthermore, the concrete strength is also increased by a lot and hence can be stressed further. Very ideal for long span prestressed bridge. You can read about it here. http://www.dura.com.my/uhpc/dura-uhpdc

Btw, you are a QS right?

hehee

Umbrella Corp, operator quite high wages also. anyway is dangerous la. there are incident like their head is chopped when operate forklift.

Umbrella Corp, those are crane operator. no idea whether they need licence to drive those equipment or not. should need ba. all these while just order directly from machinery renting company. those machinery renting company will rent the machine inclusive of operator.

GodOfWar , with IBS and well planning, the superstructure of 30 storey can be complete is just 15 days. (of course, the substructure aka foundation work have to be complete first)


https://youtu.be/Hdpf-MQM9vY

Let me do a little correction here, Larrie chew! Compressive strength and tensile strength is two totally different thing. Tensile test is carried out for steel materials such as rebar, I-beam, Steel pipe casing etc. It is a "pulling" test so that we can know how much is the yield strength and tensile strength before failure.

Lets say we are going to construct a single storey building. Inside the columns, the designers will on use the minimum amount of steel as per the BS's requirement. This is because the column does not have to resist much moment. Heck, you don't really need rebar for single storey columns. Some people even used bricks for their columns and there are no issues as long as the foundation is stable. My senior engineer once said the only time that the rebar will come to work is when there is a crack in your column which is wide enough for you to see your rebar. Otherwise, your structure will rely on your concrete's compressive strength only. That is why for bigger and heavier structures, we specify higher concrete grades. At the same time, it will also reduce the amount of required steel area. Hence please dont just add or use bigger rebars when the specified sizes are unavailable. There is a limit too.

You can also think of it this way. Why rebars are allowed to use lappings for extensions. If it is used to handle compression such as normal steel structure (H-Sections), lapping is definitely not acceptable. Imagine it sliding down because it is tied together with a wire only. The reason lapping is adequate because we only need them for their tensile strength to resist moment. You will also never see a steel structure being built by using rebars. All of them are built using proper structural steels which have enough strength to resist buckling during compression. Rebars are too slender, hence it will buckle easily. It can be used as bracing to prevent the steel structures from buckling though.

BABIKING Yes guys.....Wrong information, impracticable designs, or unclear specifications. Yup, these problems are faced by many suppliers as well as the procurement officers. Some purchase requests made by the incompetent/young Engineers with incomplete specifications on the BQ, are simply insufficient detail for the purchaser to source the right item or the supplier to provide an accurate quote.

Some Project Managers who authorize the purchase requests also do not check the required specification carefully. For example, young engineers often don't attention to the I-beams that are available in a variety of standard sizes and thickness. The same for piping standards ASTM API BS JIS DIN. When the material is delayed, they will play the blame game.

Besides, the person who performs the material take-offs does not communicate with the Engineers. Engineer obtains the BQ from them and directly fax the raw BQ (with Company chop) to the Suppliers.
04/05/2020 10:26 AM

fyi

most BQ state like this

to use wall cladding (as manufacurer`s detail) or (engineer approval- which retrn to first)

By the way, The time to erect a Prefab building is fast. I've seen how they erected McDonald's at Kulim Landmark Central in 2012.

yes DatoSeriJohnnyWalker , I like prefab. the correct term is called IBS aka Industrialized Building System.

following is just my opinion. I actually like IBS. however it seems very difficult to practice here due to the high expenses of doing pre-fabrication. huge equipment expenses require. pre-fabrication require higher cost of construction cost and hence until now not much company wanna adopt it. perhaps the recent capital allowance to increase automation in labour intensive in budget 2015 will encourage the purchase and usage of equipment and more IBS? just my thought.

Fyi also KennyDowJones ,because BQ need to read in conjunction with drawing, specification and design intent. if info is unclear need to study together with drawing. if the contract is lump sump basis then the BQ is actually just for reference.

oic BABIKING, u concern of quantity of material. but then I believe they did that concern on the magnitude of force more than material. not substantial amount of material are there also, plus this happen on ground level and not all typical level, so cost won't be much.

Guys, better get the contractor to get approval on material. if the purchase made after approval, then can use that to claim for abortive material cost.

but of course u know, if the cost ain't big, contractor also don't wanna calculative so much. why wanna offend someone that give u job? maybe they will give u even more job in future if u please them? but at the same time they also ask supplier to absorb. if supplier calculate so much also, main contractor won't buy material from u in future also. so it's ur call

YoungTycoonWILL Just wondering guys...

(1) Is the Contractor liable for design produced by a nominated sub-contractor?

(2) If the Architect’s design is faulty, but the Contractor builds it badly, who is liable?

(3) Say a contractor, working under a PAM'98 contract, knows broadly what is required, but does not have drawings or specification which shows precisely what is required. So, the contractor thinks it knows what to do and carries on with the work to its own detail. Subsequently, the detail fails with serious consequences. For example, it might be a badly constructed roof detail, an inadequate stanchion base or perhaps wrongly positioned heating pipes. Is the Contractor liable for something done on its own initiative?

fyi

good question

good question biggrin.gif

(1)
there are 2 type of subcontractor namely domestic subcontractor and nominated subcontractor. main contractor have direct contractual relationship with them so if any of them in default, main contractor will have to be liable because after all they are main contractor's baby. the differences is that when nominated subcontractor in default, main contractor can claim those damages against employer if nominated subcontractor not capable of remedy the damages. the reason is because there is a collateral warranty between employer and nominated subcontractor and hence privity of contract established simply because of employer selecting the nominated subcontractor.

but for domestic subcontractor side, main contractor cannot indemnify against employer for all the fault due to the DSC as appointing of DSC is nothing to do v employer.

(2)
Architect. provided u can prove that his design is not workable. there is 1 term called Frustration in contractual term. refer wiki link abt what is frustration

ie. In the law of contracts, frustration of purpose is a defense to enforcement of the contract. Frustration of purpose occurs when an unforeseen event undermines a party's principal purpose for entering into a contract, and both parties knew of this principal purpose at the time the contract was made. Despite frequently arising as a result of government action, any third party (or even nature) can frustrate a contracting party's primary purpose for entering into the contract. This concept is also called commercial frustration.

example of frustration is let's say suddenly government announce that material "x" is banned, then it's a frustration that not due to contractor fault.

however if it was proven it's self-induced frustration, then it contractor own fault. this mean the frustration happen due to contractor incompetence. it's duty of contractor to raise up the issue during tender stage. when u accepted the condition during tender stage, u deems to accepting that it's workable.

(3)
yes. u know a term called "silence in golden", apply here so nicely contractor have to request information from consultant when it have no detail. contractor shouldn't take risk propose own thing without seeking approval. after all, if consultant delay in giving information, detail, it is contractor right to claim for extension of time and hence u got loss and expenses due to prolongation.

And if not mistaken Ageson will be one of the biggest construction company in near future, CCCC and those big project...............You guys soon will see!

BABIKING

for MRT project, MMC-Gamuda construct all the underground station. for elevated track and elevated station, MMC-Gamuda doing management. they manage those contractor that take different packages of all the elevated track and station. those contractor is gadang, suncon, ijm and etc. from thereon, gadang, suncon, ijm actually not doing physical work, they manage their subcon to deliver the work to them. and that's how construction work can used to stimulate economy.

YoungTycoonWILL

1. actually I no idea the exactly function of lacer bar in beam. usually it used to hold the "cage" prior concrete casting. ensure the beam "cage" is in correct shape and position prior concrete casting.

2. bonding tie is also use to hold the rebar. in case when casting concrete it give way go to left or right. it need bonding tie till full length base on the spacing mentioned in the drawing. however if u mention those exposed starter bar that reserve for future then it's just few layers.

EVERYTHING BECOME CONTRACTOR`S FAULT YoungTycoonWILL ......

as usual....

just share my experience in supplying projects...

one job has five consulant

C&S
M&E
environment
safety
medical consultant(for hospital)

when consultant M&E say I need this steel to be erected here to has stiff suport

then next day consultant C&S say cannot as it may increase its weight per area

soon safety consultant say can, but need to shift it...

in the end, all cost boils down to contractor

OH about that It’s so easy for Dr Noor Azmi Ghazali, he can simply say sorry and move on, while all those who broke the law had to either go to jail, pay fine or do community service.

Being the deputy health minister and holding public office, he should lead by example and be held to a higher standard of duty and accountability.

Instead, he is laughing it off and making a mockery of those who are in charge of administering the laws.

The authorities must prove that they mean business by taking stern action against Noor Azmi, Perak state executive councillor Razman Zakaria and the rest involved.

NancyDrewWhite BABIKING, Don't worry, Bill Gates and the vaccine lobby will make up the difference. The WHO has proven to be good at pushing an agenda.

YoungTycoonWILL Just asking how often ppl design pilecaps to be interlapping with the slab.

i mean beam also inside the pilecaps, slab also inside the pilecaps..
29/04/2020 2:24 PM

fyi

I no idea how often. but I encounter this design also. not very often la. usually beam connected to stump of that pile cap.

ops, also reveal that my core is not engineering

lolz...........no comment on that

BABIKING Bro, I understand just how you feel as I went through the experience.

Sometimes, you have to kawan- baik² with the Resident Engineers.
29/04/2020 2:37 PM

fyi
actually it's the ICE that cause trouble. Well, he's just doing his job, I guess if there is no ICE then everything will be very cincai.

Just wondering, babiking...

for some package the method statement go thru smoothly whereas for other package (like mine) it go through quite a few revision before they satisfied. u can tell when u use other package for reference and you see they code 1 after 1-2 submission already ... lol.

yes NancyDrewWhite

for some package the method statement go thru smoothly whereas for other package (like mine) it go through quite a few revision before they satisfied. u can tell when u use other package for reference and you see they code 1 after 1-2 submission already ... lol.

WPC do a lot of other things as well, most of paperwork that MGJV do is related to SI and from what i can see they are not willing to take the lead in resolving intra package matters. U see how they are damn slack in coordinating things, always push to WPC and ask us to resolve among ourselves.

NancyDrewWhite , i just want to point out that mmc gamuda engineers do not do paperwork. They REVIEW paperwork submitted by WPC (works package contractor).

For some package the engineer is very slack while for some package the engineer is quite rigid, so it differs, some things that cannot pass for my package will pass for other package and vice versa.

Anyway it's up to the ICE (independent consulting engineer) and the MRTC observer to comment bcos even the MGJV ppl want to push the paperwork through.

And all these thing in the end come up to taichi here and there, make sure that we hit all the QRM target and looks good during the meeting is good enuf.

Babiking! If underpinning work and enlarging the columns at below level are sufficient to cater for the load at upper floor, I believe its not necessary to demolish and rebuilt the whole structure.
29/04/2020 1:41 PM

fyi
with the underpining cost and enlarging works, might as well u demolish it as u need to cater a new stair case as well

Correct DatoSeriJohnnyWalker !

BABIKING fyi

if u have money u can become developer already. u don't need to have architect background because u hire architect's service.

how developer work? for developer that have money but no land, they will conduct feasibility study. I draft a simple feasibility study format below la.

first they have to come out the GDV first. (Gross Development Value)

100 unit x 1200sqft x selling price base on the location market price (say KLCC at RM1500/sqft) = 180millions

now with this 180 millions then reverse study on the cost by key in following detail
1. Land Cost, A
1. Consultant Fee, B
2. Building Cost, C
3. Local Authority Contribution, D
4. Finance Charges, E (of course developer will borrow money from bank to finance their work as they have no cash)
5. Marketing & Advertising, F

A+B+C+D+E+F = G

6. Profit Margin, H

G + H = 180 millions
H = 180millions - G

So if the H (Profit Margin) is acceptable, then they will proceed it.

Of course above is a simple 1. in actual it's very detail as they have to estimate the most accurate the possible.
