Baba, l did not instruct you o! Who l be?
I just made a humble request ni o.

Your post does not contain the calculation, though it has the Results or Conclusion.

I am of the Opinion that the person with that Bungalow will not need a three phase connection for his Bungalow, (the only advantage is that you can switch phases when one phase lacks power and others have power, the cost lies in more than doubling your wiring needs and switching accesories).

Until we see your calculation, it will be difficult to agree or disagree with it.
When l have the time, l will dig up something similar that calculates the gauge of Wire, based on the overall load. I know l have it somewhere in the past.

Also, quantity of wire required will largely depend on the span and shape of the building and wiring type (Conduit, Surface, Structured cabling).
That is why l would advice everyone to buy enough wire but keep vigilance on how it is use so that "wires dont start flying over the fence" 9as my friend said) and then request for more wires start coming in.

Hello,
how many blocks will one bag of cement set on the average?

Thanks

Good mornin family, I need your help for my roofing project. My engineer is one guy that I don’t understand. Can you please help me with this quotation for the roofing of this small project? I have attached the house plan for easy assessment. I will be happy to hear from everyone soon. The house is on 30/120 and the size of the house is 21/70. Thank you all

Hum2020:
@segunrusell I will advice you to contract money121 or call him on what up 0805310359 he will be of great help to you because the price your engineer quoated is high so reachout to our able moneyv121 thanks

This is a quick appreciation shout out to Gbadexy for a Wonderful superstar job done for us recently. Haji recommended him some yrs ago, I kept his details and continue to monitor his work here. He blew us away, like others have said before honest, a Pro and a good example of a wonderful Nigerian you will be proud to deal with.
We roll on to the next project Gbadexy, people for your painting jobs call Gbadexy for peace of mind.

Please how good is N.W.C. Denki wire and cable for house wiring? My electrician rates it above Coleman.

I am glad you are not disappointed too. Gbadexy is all and more of your description above. I can give him a job and go to sleep.
Gbadexy, keep up the good work Sir. Thank you.

It's a bit higher, tell the engineer to reconsider his quote a bit from materials to workmanship which is believe is the Carpenter charges only.

I normally use previous projects done to evaluate future project management and approaches. By area the building isn't as big as the estimate should take. I know how much I used for this building I did for a Nairalander here

My opinion though.

Segunrusell:
thank you so much for the response, my uncle actually said the same thing but this engineer is always doing this to us. Inflating everything and telling us it’s not easy to work from upper floor that if it is a bungalow it’s different case entirely. How much is good for the workmanship. I’m thinking of telling him 120 or max 130k

tevanso:
where is the project Sir.

Segunrusell:
somewhere around ikorodu

Try professionals here too, we are not only good in given quotation or criticizing non nairalander
Quotation here sir, others do patronize us here too.
God will give you more power to finish your project Amen

Segunrusell:
thank you sir, well I did created a thread for the project asking who can roof the project. I just received a quotation and we are still negotiating. I’m trying to get the best and pocket friendly offer so we can get the roofing done ASAP

rotecch77:


Oh that is good to hear sir, your power of negotiation is very necessary while negotiating with any body that submitted quotation.
More so the cheapest price doesn’t mean good work oo.
Ask the person to show you his previous work or to take your brother there to see . (That is if the said person is nearby).

Segunrusell:
I will do as you have said. Thank you for the input and at the same time can you pls help vet the quotation a little? I’ll appreciate sir

Daboomb:


Well done Sir!

Thanks for sharing your calculation.

There are a few things l will please want you to take not of:

In your calculation, what you used are what we call 'absolute values" in that they are the maximum limit of power the house can draw if all appliances are IN USE and drawing Maximum Power concurrently but a few things are going to be obvious:
1.) A ll the 4A.c's wont be on at the same time.
2.) Even if they are, they wont all the on and the Cooker, Water heater all still on concurrently.
3.) Even if all those are on, all the 13 Amps Socket wont be in use at the same time
4.) Sockets are rated for the maximum power that theycan carry but we all know that when we dont plug any appliance into a socket, NO POWER is drawn from it, which means its power consumption at that point, from the Load wire, is ZERO! So, most time, only a few Sockets are in use and drawing power from the load wire. Others are idle.
5.) Some appliance like TV's, Laptops, Sound System, will draw less than 35W, yet each on is plugged to individual Socket!
6.) All 35 Bulbs in the house wont be on at the same time, some might be low-energy LED Bulbs that draw only 5W of energy so, they all will draw a fraction of what your figures gave!

So, if you look at it, IN REALITY, at any given time, REAL POWER being drawn from the 10mm load wire is less that 45% of the total POSSIBLE Power Consumption of the House, that will pass through the Load wire, at the same time, for a single pahse wiring..
Same reason Engineers use the 16mm as load wire, for single phase.

I have never see any house where appliances like Boiling Kettle is plugged to all their 15Amps Socket, and Appliances are in all the 13A sockets all at the same time, with AC and Water Heater balrring and food cooking on the Cooker, e.t.c ....all at the same time.


This is why l and some will agree that a 10mm load wire, (and from experience), is adequate for the load of that the poster suggested.
All the same, l thank you for your effort and opinion.
Respect.

My Good morning people.
Trust we had a good day yesterday.
Please I am seriously considering my financial status but still wants the best.

Parapet vs No parapet

What are the pros and cons.
This is where I am now at. I am considering casting the beam and roofing or casting parapet before roofing.

My pocket will tell.
