power float + floor harderner and power float only. what is the difference?
*
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" laugh.gif

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

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?
*
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.

Thanks! notworthy.gif

(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 whistling.gif?

(3) Does the Clerk of Works has the power stop the Works? unsure.gif
*
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 smile.gif

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??
*
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.

should I build 2nd storey for my house? to build 2nd storey is expensive 2x cost of the 1st floor? how can I renovate my house with cheapest rate? I still have 180sqf free at the back of my house(for bedroom and kitchen) and plan to have 2nd storey too for dry the clothes. should I build 2nd storey?

2nd storey overrated?
*
expensive to build coz u already completed first floor without consider the foundation for 2nd storey. by add 1 more floor, u need a stronger foundation, stronger column and therefore a lot of abortive work need to be done. eg. such as u need to strengthen the column, do the underpinning work to have stronger foundation. perhaps hack off some ground floor slab just to increase few more footing and so on. need to engage consulting engineer to come out the drawing for u also. ain't cheap.

is it cheap or just a clueless act to build just 180sqf for 2nd floor? I think I just wanna hire indon labour to avoid expensive cost from engineer. Indon laour is enough and I will not tell local authority ma because I am in G&G residential and it's only 180sqf without roof for 2nd storey
*
it's not advisable to do it without getting endorsement from engineer and approval from local authority. even u can over design it to ensure it's perfectly secure, sometimes unforeseen thing will just happen. if something happen and even not due to ur fault, not due to ur structural design issue, they will still pin point at u as u didn't get endorsement for the work and no approval from local authority at first place. so u lose the case b4 even it require to assess ur secured design.

anyway it ain't expensive also la. all those material is cheap. maybe u estimate about RM125/sqft for ur work. normal finishes, not expensive type. but endorsement and local authority expenses would be a lot as ur quantity is small yet the same procedure had to be go through.

Does 4(a) says it's OK if the house is for the proprietor or the occupier, or their servants. Subject to the house not taking up more than 20% of the land area or 2 hectares (which ever is less).

I assume this is so the farmer can live on his own farm, so that he don't have to commute from a separate house very far away. So the farmer can build a house for himself, but not 10 houses to rent out.

Or am I reading it wrong?

yes.
