power float + floor harderner and power float only. what is the difference?

Is it true that for one project that cost RM1.5b, a consultant company would only employ one QS?

good question

therefore main contractor is not an easy job. u got main contract (agreement between employer and main contractor) and also subcontract (agreement between main contractor and subcontractor). u have to always ensure that whatever subcontractor claim to u is claimable against employer. but this not always the case.

remember that in standard form of contract (irrespective of it is PAM form or PWD) there is 1 clause mention that the contractor have to notify architect the discrepancy of drawing and any doubt during tender stage. upon contract formed, contractor accepted that all the information is clear to him. so if during construction stage only contractor discover certain blindspot he overlook and after enquired architect on the original design intent, some additional cost have to be spent on the said changes. all the cost incurred on such changes shall be borne by contractor. those cost incurred have to pay to subcontractor because subcontractor is just construct whatever u asked for. they not bound to the mistake contractor didn't discover as they only take care 1 trade while main contractor take care everything.

so this is the logic behind ur concern. the principle is that if the discrepancy only clarified during post-construction stage, all the cost incurred to fix the discrepancy is not claimable against employer. but on the other hand the discrepancy could be a cost saving to contractor too. example contractor price in marble material in cost, but there are discrepancy on drawing on finishing and upon clarify from architect, tile is their original intent. therefore change from expensive marble to cheap tile is additional profit to contractor as no cost implication due to discrepancy.

u can give but they will follow u the rest of ur life when they need from u.

powerfloat mean direct finish on concrete. power float is a machine look like helicopter but upside down 1. after u cast concrete, then u will use this "helicopter" to spin on the floor make it smooth. hence no need do additional floor screed after concrete cured.

power float + floor hardener mean u spread the floor hardener powder on the floor slab when the floor slab concrete still not yet set (not yet dry and hard mean) and then power float it. it is like a coating to concrete floor. have strong mechanical properties. hardly crack. can stand heavy duty implication. in residential and commercial building, normally it is use on car park.

power float machine aka "helicopter"

Developer will engage a consultant team consist of,
1. Project Management Consultant
2. Architect
3. Engineer (M&E and C&S)
4. QS
5. Landscape Architect
6. ID (optional)
7. Lighting (optional)

so basically developer engage a professional service from consulting QS firm by paying them about 0.8% of building cost. let's say the building cost is 500mil, then the QS professional fee is 500m x 0.008 = 4mil. developer generally don't care how many staff the QS firm put for that project, as long as u deliver ur professional service that's it. nowadays, consultant firm will put a QS to do a project then will have senior to overlook the QS la.

Thanks!

(1) Can the Main Contractor refuse to comply with an Architect’s instruction which requires the acceptance of the quotation of a Sub-contractor chosen by the Architect?

(2) If the Employer gives instructions on site directly to the contractor, must the Contract follow-up with the Architect to confirm those instructions in writing? or just ?

(3) Does the Clerk of Works has the power stop the Works?

If found discrepancy and decided to use tile instead of marble, why the employer cant get the saving if error in BQ specified marble but drwg specified tiling? Cant the employer have the right to do variation order?

Reali macam helicopter.

0.8% is so high... I heard of companies going for 0.2X% before.. But measuring one huge project is really one hell task..

then in what condition to choose between power float finish and cement render finish?

oh ya, forgot mention that it's lump sum contract (eg. pam form without quantity). nowadays mostly construction main contract is adopting contract in lump sum basis. the reason behind is because of client have a budget for the project and therefore want the contractor to study through drawing and price it. in lump sum contract, the drawing take precedent. bq only as a reference

in contract v quantity, the bq take precedent, therefore anything not in the bq is addition, anything extra in the bq is omission (saving to employer). however there would be some discrepancy / unclear info that will induce a saving which the employer not entitle to deduct also. eg. drawing mention that using dark grey tile and bq mention dark grey tile. to contractor, he assume that dark grey tile is dark grey granite tile so he price it base on granite rate. turned out it's a homogeneous tile after clarify v architect. so contractor subsequently pay low for that work and still can claim accordingly.

factory, car park with bear finish usually use that. heavy duty. cement screed require when u have some finishing on top such as tile, timber floor, carpet and etc.

cement screed same with render? i thought screed is just for leveling so that u can put other finishes on it. rendering is a bit thicker. i saw some area finish directly with power float but some finish with cement render only??

1. subcontractor chosen by architect, we called that nominated subcontractor. contractor can reject if he got a good ground. this is stipulated in the standard form of contract.

2. yes, contractor should write in not because of they have to do that, but to put thing into writing and serve to architect. in future got dispute these would be the evidence.

3. yes, they can stop the work. they represent architect. however if stop wrongly then the contractor can claim for expenses due to the hindrance of regular progress

ya, cement render mean put cement screed then apply trowelled finish on the screed. the screed can only be lay after concrete slab cured.

powerfloat is direct finish on the concrete slab. when concrete still wet, they use the "helicopter" to spin the make it smooth finish on concrete and hence called direct finish.

how to read the drawing plan and transfer the scale to a dimensional paper or slip sort based on SMM2?

Bro, maybe you should open a similar thread in Property Talk to help fellow homeowners. One question, my new condo is going to be ready soon, from your point of view, what are the things I need to look out for, i.e. areas that construction companies / developers can skip on or most likely to have problem with?

Your thoughts on Prefab housing?

Mostly contractor refuse to use waterproof systems
