Well done.
The concept looks nice, so this is the L shape that I always hear about. Whats the total area of the plot and how many sqm will the building take ?

The built up area is 460sqm on about 1000sqmt

danowena:


What u gave is close to what he gave. . Na wa o o....that estimate is going close to 3 mil.

....

1.5mm- 92 vs 60
2.5mm- 60 vs 48
4mm- 36 vs 13

That's about half a million diff , and it's a worst case scenario. Everything ultimately depends on your piping network and the size of your rooms . You could even "manage" 4mm for the cooker

Volume of tank is 22/7 multiplied by radius squared by height

(Diameter squared)/4 is the same as radius squared

Oga Skimanski, I have questions that I could email you privately on but others might benefit.

I like your electrical layouts and hope to borrow some design elements, an example is laying my switches in some areas on the vertical plane.

Do you work off of an architectural electrical plan provided by the client or you design your own electrical plan?

Do you put your wall outlets in the middle of the wall or offset to one side of the wall?

In the Nigerian concept how do you decide on where to locate the distribution boards?

Thanks.

check up my thread.. we are doing an electrical installation for a duplex..

this might be different a bit because there is whole house automation coming up.. ( controlling your appliances via a phone apps).

we have two db for this project, one on the ground floor another on the first floor.. (D4 ABB for ground floor D6 ABB for first floor)

My Oga Good day sir, Your boy dey greet you.

Once i receive a drawing with an existing Electrical plan, I first and foremost go through the drawings and then do a layout then adjust the drawings to suit what truly works in relationship to the clients requirements. Mostly, electrical drawings over here are just copy and paste. Put a light somewhere in the middle and points around and sockets switches around. What I do is I dont just locate the light anywhere, I have to think of that person that comes home late at night tired and wants to switch on the light. That guy that wakes up at night and doesn't have to standup to turn off the A.C because its become colder than it already was before he slept. a whole lot of factors come into play. Hence the reason for a layout. The existing plan can just be a Guideline to what the Architect and his team where thinking.


The wall outlets are placed in a way that its easy for who comes into the space when its dark to locate the switch. Be it in the middle of the wall or close to a side.

Now as for DB (distribution Boards), there are few factors your should outline before you decide the location for your house, not necessarily possible that all these factors must checkout, but taking them all into consideration will help decide the best place. Note if these factors together makes you feel your living room is the best place it should be, then put it there and you'd have done nothing wrong.

1- AESTHETICS: Its nice that the DB is out of sight. Not nice to have your DB at a location where your have put some time in trying to make it aesthetically pleasing. Best to be in a Hidden location, like Storage, Hidden rooms or corridors, Box rooms, and better still an electrical room in the house.

2- PROXIMITY TO ITS TWIN: In the case of an added floor/s or a larger area that requires 2 or more DB's, its nice to have then in a location where their linking to each other isn't far off, as you'll have Load bearing wires (16mm size wires). going back and forth in three ways (Three face Light Connection). This will minimize your wire cost as one 16mm Wire these days is N42,000/roll.

3- PROXIMITY TO CONSUMER UNIT: The consumer unit where you have your meter and/or change over locations is also a factor, as you will also not want your DB to be too far from that location, because thats the location where the Power source gets into the house and its from that location the house pics up the power. So to Help minimize the cost of wiring (16mm wires) as well, that should be looked into.

Well said, the location of the distribution board should be hidden in such a way that it will not be visible by the visitors. Location of switches is one of key point to be noted when doing electrical installation. Switches must not be located at the of the door. That is why electrical design drawing is very important during installation. But in a situation whereby there is no electrical design drawing, Architectural drawings should to be studied strictly and understand the doors openings.

Very good points my able friend, but on point one, I love the DB to be in a slightly hidden area but also consider accessibility and the need for the DB to be in a place where it cannot be locked out in case any quick repair/intervention is needed. I have seen smoking and fires sometimes starting from faulty boards, supposing you want to use an extinguisher and cannot get into the electrical panels due to its hidden position?

I think the materials quoted here is enuff to start a mini warehouse for wires.

Electrical works could be very tricky. It is not just all about the length or rolls of the cables. The pipping work plays a significant roll as well and the design, position and quantity of points or outlets: How many plugs per room, living room and dinning, fan points, security lights or not, side lamps at every wall etc will add up to the quantity of cable used.

Below is my outlay for a six flats. Mind you, my project is mix-mode: 2 units of three bedroom flats, 2 units of two bedroom flats and 2 units of one bedroom flat. Two toilets each in both the 3 and 2 bedroom flats and one toilet each for the one bedroom. Mind you, if you have all ensuit, you will consume more cable.

My outlay includes Generator point for all flats, A/C point for all rooms and living room and two points for water pumping machine:

QT................................Cutix Cable..................................................................Unit Amount.................................Sub Total

25 Rolls of 1.5mm-15 Red, 10 Black N5,500= N138,750

38 Rolls of 2.5mm - 14 Red, 14 Black, 10 Yellow N9,350= N355,300

1 Roll of 6mm N21,800= N21,800

2 Rolls of 10mm - 1 Red, 1 Black N36,000= N72,000

3 Rolls of TV Cable N3,500= N10,500

Workmanship 250,000

GRAND TOTAL N848,350

Can you do sometime about your labour cost? 600k? But be mindful of over bargain to rock bottom price as you may encourage the eletrician to cut corners to make up. There is a fine line between fair price and slave price. I hope this helps.

As long as you dont set it on fire (the fumes are very toxic), you are good to go with PVC.

Now, l am of the opinion that in 2016, NO ONE (at least not me) GETS UP FROM BED to SWITCh-OFF their A/C or a light or come into a room looking for a light Switch!

In the current system of "connected things", you enter a room and the motion detector 'detects' the presence of someone coming-into the room and signals the light to come on for a pre-determined length of time, after which it goes-off if no motion is detected (This saves on Energy-cost)

There is a reason appliances comes with a REMOTE CONTROLLER!
There is even a MASTER-CONTROLLER which controls all other Remote-Controllers so that you dont have to hang onto too many controllers!
You switch-off your A/C without even breaking your sleep!

The highlighted above are not worthy of consideration, in location of light/power switches!
"Aesthetics" would be the most overriding factor nowadays while "cost" (cable length) should come second.

But then, l understand if some still want to stick to the "traditional" way of doing things. [/b]

I very rarely have to touch any switches in my house now. I say rarely because of course things sometimes doesn't happen fast enough sometimes (like a midnight download and the loo light just isn't coming on )

Thanks Chief EgunMogaji

Yep. It's extremely DIY and you can even knock it out professionally with what Samsung calls SmartApps from the built in Marketplace. As a quick example I use Amazon Echo to interface voice control. I'm not digging out my cellphone to make commands and simply just use voice to tell echo to turn on/off lights (those not on motion sensors), turn on music, etc

It's the same principle between an existing build and a new build with a few differences. For example, I was not going to wire any switches to my wall but the Wife won't have none of that. Having wired switches is no longer necessary so you can save that money on wires and outlets. The bulbs themselves are iOT so you can address them directly. The wall sockets are iOT so they can turn on or off any appliances connected to them so you don't need a switch.

The door and window sensors are battery operated (3 year life) as is the motion sensor, so you totally eliminate all those traditional wirings.

So as you can see we're already saving wirings and sockets if one dares to go that route.

One of the reason that I'm going 120v versus 240v is that there's a larger market of 120v accessories versus 240v to me.

Let me know if you have additional specific questions.

Note: A big issue, because it is the internet of things, these requires full time internet connection. If you don't have full time internet then some things will not work but controls for some stuff will still continue to work. For example, you can still turn lights on and off but of course if theres a fire it won't alert you via cellular.

But there was a conversation recently on here that alleged unlimited data now in naija.


-------------

Found these on Smilr

We all have several demands for unlimited data, only concern here is how reliable these services will be as we all buy in.
I once went to an spectranet's office as a new customer to buy their service, while sitting in the reception, all the customers in their office that day were for one complain & failed service or the other.
I went back home that day with out buying.
This was my own personal experience, if things are actually better than this, I'd love to know.

Uberness:

Internet is not the obstacle. We have it. The last mile to the consumer has always been the prob so I use legacy devices to reach my ISPs and do basic NATting to use 2 ISPs on one router. One as backup while the other is the main link.

You just need to know how to do load balancing and have a good bandwidth manager to allocate resources to priority users/devices.

Meraki USA is one good device I've used for this before. You may also look for other good routers with Dual WAN. TP-Link has some budget priced ones.

Trust me the InternetForThings is there anytime, anyday.

Internet users will always complain like PHCN customers because most ISPs don't have a reliable support service and do not have experienced WIMAX engineers. All they want is to recoup their investment even if it means "no value" to their end users. Some times, the basic modem/router supplied to end users may not be enough to deliver right service to user but what they do is to just sign ion people without considering how they'll be served.
One easy way to get it right is to let them know you want dedicated Internet and sign a 99.9% Service Level Agreement with them.

Some will argue "Can this happen in Nigeria?" And I'll say "Yes, it is possible" but at an extra cost.
