wiring..

Question from one of my friend....

Oh, i got few quotation on the wiring for my house, A quated me RM 86 for a plug point whereby, B quoted me RM45...


Would like to share with you all on What to consider in wiring works during renovation....no right or right..it is the matter of what suit you better. And what make the pricing different.

1) cable size
Applications

• usually for lighting and low wattage usage cabling like TV point we will go for 1.5mm thick cable.
• high voltage and long usage like fridge, water heater and etc, please go for 2.5mm.

Disadvantages:

• Thicker cable will cost you higher.
  

2) Looping

Applications

1. Looping = the point which continue from the primary point.
2. The more point it's loop, the capacity consist in each point is lesser.
   

Risk:

• The more looping is, same cluster (light point and etc.)might overload, and again it will harm your appliances (example, light fitting always burn off and etc).

3) Switches control
Advantages

• More flexible for you to chose which cluster of light to be on.
• Dimmer control for halogen (spotlight) - fitting will be more durable.

Disdvantages:

• The more switches control, the more works to be done.
  

Therefore, the charges of the wiring labour will relatively increase.


4) Conduit
Advantages:

• wiring run in conduit so that if in future, any problem happen to the wiring, it will be easier to classify.

Disadvantages:

• more work to be done, therefore, more expensive.

5) Hacking work (conceal wiring)

Advantages:

• Look neater and nicer.
  

Disdvantages:

• If the wired need to be conceal, more work to be done, labour cost will be higher.

I tried to make this post short (although it is kinda long still..haha...anyway..if you have doubt, feel free to leave message or email me...:)

hiring contractor-things to be consider

I think it is a good examples when we looking for supplier on any renovation project..especially those who intend to handle the renovation themselves ...
reason being, the one who quoted you lower price, might consists lots of hidden issue or cost which they will not tell you before you engage them ...And, most of the owner might not have experienced in renovation, therefore the only thing that may attracted you will be the figure...but you will never know, that's lots of hidden cost involve and they may not really quoted you what you expected...by the time you aware of it..it might be slightly too late to regret.

Yesterday went for a meeting at client's office..meeting up with 2 shortlisted supplier for my client's new office.

2 suppliers, same project, pricing different is up to 200%.

During the meeting....
Supplier A
" i divided the zone into 4, using xxx material"

Supplier B
" i divided the zone into 10, using yyyy material"

"how to justify this zoning?in stead of 3 or 6 or 12..in stead of your proposed zoning?" we asked

Supplier A
" As per my experienced, 4 zone is good enough. But i can't tell u now where the specific zone divide.."

Supplier B
" we calculated the zoning as per formula, and also the lesser zone it is, the bigger machine needed, you might be facing insufficient capacity in future, also sound will b increased . Second, the space for machine installation also requested higher..."

"any nego on the pricing?" we asked

Supplier A
" Emm...nope, the proposed price i believe is much lower compare to others competitors.."

Supplier B
" Emm...actually my profit margin is quite low, i am not sure how much others quoted you, but i believe it is different proposal that's cause the price differently....."

"Future maintenance?" we asked

Supplier A
" can be done by appointment.."

Supplier B
" we include 2 years free maintenance....."
