Thanks for the info. I am trying it out right now.

depend on what kind of contract u enter. lump sum contract? or contract base on quantity constructed? contingency sum is for the sake of some budget to be buffer around in case additional cost require due to some issue that arise in future. provisional sum is due to the cost of work cannot be determine so they allow as provisional cost. in future the cost could be less or more than provisional cost. but better allow some instead of nothing right? the client thinking is always there have a cost in mind they don't wanna forecast wrongly. imagine u wanna sell a house to purchaser, u have to determine a selling cost right? if in future u need more cost to build, do u think u can change the selling price that u had sign S&P agreement with purchaser?

Traditional = client engage consultant to design and engage contractor to build. design to come out first b4 contractor can bid the price. taken up time but cost is certain b4 construction start.

Design and Build = client engage contractor to design and build. this mean contractor will engage consultant in this case, not by client. cost is uncertain. however depend on what kind of contract contractor enter, some competent contractor can give an agreed price and guaranty satisfy client by a conceptual idea given by client. that's the competency! contractor that get the job will start the work even the design not complete yet. design and construction do concurrently.

Management Contracting = this is unusual here. reason is commercial issue. client always have a budget. but the cost cannot be determine b4 construction start. the cost only can be know part by part progressively and final cost only can be certain during final stage.

QS is an option. not really require if the cost can be agree between client & contractor.

1. depend on what the client want. got plenty of land, build landed, got no much land, build high rise. beside that also see if the developer is target which market. with garage mostly is rich pipu, no?

2. excel is just a spreadsheet. just table out the item require and price it. like u need Qty x Unit Rate = Amount. example 3m3 concrete x RM300 = RM900

3. want to be profitable? just use pearl grass / cow grass. cheap and green

good brick need furnace to burn, clay brick. so, no thanks. don't really need cement sand brick.

go weight urself? gauge 22 (0.644mm) is bigger than gauge 28 (0.321mm). curi ayam?

small hole? use those sealant that is paintable 1.

4000 x 200 = RM800,000 lo

what work u wanna tender? all trade? or just certain trade?

depend which level u want to be in. there are many party 1.

main contractor don't have much capital. they just hire a management team, they have probably some cash flow capacity, then they hire subcontractors do the work for them. client pay main contractor, then main contractor pay subcontractor. main contractor just earn abt 5% profit only. example client pay main contractor 155, so RM50 goes to expenses and overhead main contractor incurred, RM100 go to subcontractor, RM5 is profit.

generally main contractor is a middle man that don't have any labour and material but still can delivery a building and making money.

just like uber is a taxi company that didn't own any vehicle and they don't fetch passenger personally and yet still making money.

just like airbnb is a house renting company that didn't own any houses hence they no property to rent yet still making money.

just like alibaba is a company selling goods online yet they didn't own any goods and still making good money.

Just want to know, those modular houses do they need building permit etc?

if my concrete mix arrive after 2 hours batching time

leaving me with 30 minutes to place it

do i still have to pay for the remaining concrete which i can not place in time ?

yes. legally speaking

check the contract u have with the supplier. u can reject the concrete if it mention from batching plant to receiving is more than the allowance in contract.

beside that u didn't carry out slump test? it will probably fail as the workability couldn't achieve

what if its on per order basis and thus no contract formed ?



if the truck arrives after 2 hours batching time and we consider 1 hour of actual use time
and the concrete workability to still stand during the whole 3 hours

but no matter how we cannot finish all the concrete mix that we have ordered before it loses its designed slump

thus we have remaining left

how do we go about this ?

that's why u have to be careful when u order concrete. tell them ur requirement. I believe ur project also got spec. for concrete right? eg. if the concrete spec. require is 30 minutes for concrete to be mix (in batching plant) and completion of placing at site. for pump mix is 2 hours, then u have to tell the concrete supplier to comply at beginning.

if the clerk of work is competent, he see the delivery of concrete already take 2 hours, he will reject and not allow u use that concrete.

aih

project at place where delivery is an issue and thus sometimes the delivery time is very hard to predict

ya. that's abt competency. not easy I must say, coz it also involve of a lot of pipu inside this construction work.

thank you for your advice

come to think of it why would any construction material increases when fuel price is increasing?

yes. 羊毛出在羊身上
