To me it doesnt really matter what architects charge whether 6 or 7%, I dont see the value.

I think the challenge is to the above mentioned building professionals to actually to much more work in not just educating the investing public but also adding value adds. I believe maybe I can pay that for a 'green' building as the savings will offset the initial cost.

@mwenza/litro funny how some react to forums. who asked for a PJ? please read my posting again.
are you suggesting I am not aware of CAP 525?? unethical?? what are you talking about?? I am offended by your insinuation that I am unethical.

@Kaigangio-- i loved your concerns about the role of the QS. Way too harsh on the QS's, many QS's have delved into specialist M&E and even roads. QS's are very good at interpreting structural drawings,perhaps on that point you onead them.
QS's are also highly skilled in contract management providing valuable inputs in claims management. They have a lot to offer.

We do not dispute that. The point is, a Qs is duplication of effort as explained in the other strings.

A quantity surveyor(referred to as a cost engineer in US) is important any construction project design team. Its true that u can do without a QS in a project, but the value added when one is involved can not be refuted.

The architect is trained to interpret a clients requirements into a concept/a form.. and thus he comes up with an architectural design. From this architectural design, the structural engineer is called in to do the structural design for the architectural design to be achieved...

the importance of involving a Qs in the design team is to assess the cost implications of various designs. And by so doin, at the very initial stage of the design, you will be designing to a cost and not costing a design as there is usually what the client can afford ie the client's budget.

there are the various stages of design:-
1. inception/feasibility stage - the QS will assess the feasibility of the project in terms of affordability and value addition.
2. Outline Proposals - After the initial feasibility studies and preliminary estimates have been prepared, the Quantity Surveyor prepares the cost plan from the Architect’s preliminary drawings. The cost plan divides a building into its various functional elements and allocates costs to these elements. In this way it is possible to ensure a proper apportionment of expenditure over the various elements. Proposals for alternative materials and designs are costed as the design progresses and the cost implications are presented to the client and other consultations are made with knowledge of the overall cost involved.

3. To be short, after the design is complete, the QS will prepare the final BQs. Bills of Quantities are the translation of the designer’s drawings and specification into describing the building works in words and quantities. They enable each contractor tendering to estimate his price on exactly the same basis as his competitors. the BQs provide a basis for the financial management of the contract.
4. Construction stage - Cost control - the QS uses the cost plan prepared in the design stages as a basis for cost control during the construction process.Variations sometimes to take account of the client’s changing needs, sometimes to overcome site conditions which could not be foreseen such as the presence of underground site conditions _ The Qs estimates the costs of proposed variations and reports their impact on the probable final cost, so that corrective steps may be taken elsewhere in the work, if the client requires, to keep the cost within the budget.

The QS will prepare at regular intervals financial statements which keep the client and designers fully informed of the up-to-date financial position and the anticipated final cost of the work.

5. Valuation of work in progress for stage payments
6. Preparing a final account by adjusting the contract sum in accordance with the terms of the contract to take account of any variations, of adjustments in the accounts of nominated sub-contractors and suppliers and of any other matters for which the contract allows.

@Kaigangio & all,The QS is adequately trained in construction law(contract, tort, agency, land laws,..); architectural and structural design; economics; management; accounting; .. just to mention but a few. Their specialty is cost management and construction contracts.

Just like u go to a shoe shiner on the street, or take a taxi while u cud do shining and the driving urself, an architect or a civil engineer cud as well do what the QSs do, But i think the ideal thing wud be to leave everything to the specialists. We can not do all,

each person in the design team has a special role, that is why each is a professional. the architect cud as well do the structural design..,Fundis can design for u and build if its a matter of saving costs..

@ muthurimugi

Great response. I totaly agree with what you have said.

I am currently building a villa in Mombasa. I have a architect at 6%, Structual engineer at 2% and a QS at 2%. So OK, it is 10% extra but I can tell you from my experience so far that it is WORTH it.

As I am in Nairobi, that is the ONLY way that I can be sure that the contractor is building to the specifactions in the design documents and the what his detailed response to the tender was.

It is also VERY important when you change your mind about something, ( which WILL happen during construction ) I am in Mombasa now for a site meeting and Mama has changed her mind on the tiles to be used in the kitchen. With the QS's Bill of quantities, and the tendered prices, we now know exactly the cost of the replacement.

Guys, my advise - DONT take chances. It could come to bite you later.

Thanks

How do you estimate the entire cost of the project so as to have a baseline? I contend the notion that the originators of the design can come up with the cost estimate, since they dont have the necessary training on how to estimate costs. Who prepares the estimate?

There is something called Engineers Estimate. There are softwares that design and produce quantities.
Personally, i don't understand why i do a design, prepare bar bending schedule, get the total kilograms of reinforcemnet required then all the QS does is multiply the kilograms by unit price.
He does the same to the volume of concrete.

For contract management and standard documents, you can use FIDIC and PPOA documents which can be downloaded from the link below.

Holy cow... now insert that software into the robot and send it to site to measure the percentage of the work complete..

use the same software and put it at the table at the site meeting and let it explain to the client why the depth of the foundation has changed due to conditions on site...

later send this software to tile and carpet centre, saj ceramics and dubai to ascertain that the quantity of tiles it required are i. available ii. dimensionally stable iii. the colour the architect has specified

after that ask your software to negotiate payment terms on your behalf e.g. the deposit to be paid, method of payment..

ask it which the best way to pay LOC, Cash, RTGS

It appears you have forgotten a basic tenet in computers, GIGO (garbage in garbage out)

your comments on the PPOA do not deserve a response from anyone who has ever built anything..

@holycow,

As fantony has put it, these free software tools dont do the job.

I have worked in the IT industry all my life and have even paid for software related to building your own house.

However, that does not mean that you dont need a QS.

Read my message above no. 36.

Unless you want to be the QS on your project, it is not possible. 1) you are not qualified
2) Do you have the time
3) If as in my case the project is in Mombasa and I am in Nairobi, how do I control it.
4) Who gives the certificates for work completed for staged payments

I promise you the 2% is well worth the hasle you avoid.

As I mentioned in my post above Mama ( the BOSS ) had changed her mind on the tiles in the kitchen.

Since then she has decided that instead of a plain hardwood front door she wants a carved Zanzibar door.

Just looking at the detailed B of M, we can see the cost impact straight away.

I am currently waiting for my Mama to think of something else to change ( she is a very creative Mama !!!! )

I hate to think what would happen if I didnt have a QS, and had to deal with it myself on the phone of email or even fly down to Mombasa.

Save yourself the headaches and probably money by having a QS.

Regards

@Holycow, from my little experience, the quantity provided by the engineers estimate (from the software) tends to be slightly different from what was actually done on site...especially with reinforcement bars! for the concrete, am yet to see a software which can give the volume estimate..for structural steel, truth be told, the software (STRUCAD)does wonders!

The PPOA documents i think are better suited for the public sector...i do however agree with you that FIDIC is one hell of contract, and trust me, no layman can handle a project with the FIDIC contract! thus the need of a QS or a contractual law specialist (if you have a heavy wallet)
