Yes his finishing is mad! One of the problem i just have with qualified people like that is that they tend to send their interns/boys for most jobs.

When i started the project, the roofing project was given to our popular roof guy here because i fell in love with his work, on getting to the project.. I discovered that he sent his boys instead. (I no vex )

Same as the electrical/smart home/cctv contract, deal was signed with the boss but for execution, the boss sent his boys.

When we sign deals with notable brands in our homes, it’s because we want the boss touch but mhen.. our bosses mostly supervise now

If we outsource interior, i am 99% sure the main interior boss won’t show up but one of his boys.

If we outsource external floor stamping, 100% the boss won’t also show up.

For someone who want perfection and state of the art finishing, what will it take to get these Ogas to be the one to work on the site??

I know if i hire topsy, topsy might not show up but sent his trusted boys,

If i also hire My Oga Gbade for painting (because I believe he will give the best for my house) oga gbade might merely send his boy (who’s eager to conclude his work asap and get to the next project)
Like when we gave the external window designs (external POP) to one of the best guys around and we paid him in full, the guy sent his boys instead and those ones were just eager to quickly finish the project.

You need to see how rough the pop was! Very rough and the stupid boys were saying “that’s how it would be when it’s still wet, when it gets dry.. the true shape would come out” lmfao, we ain’t spending alot of money on this just for it to end up looking like a village mud house! It was painful but i ordered all the POPs to be dropped off immediately (in the presence of another pop guy that will do it).

The new POP guy did a perfect job.

The old Pop company is still begging for job till date.

Definitely you will get the best from us if you involve us.

We have our own standard operating procedure that we follow. I have supervisor

Few of SOP is as follows

When you resume to sit:
-Request for 1m level from the min contractor or builder. This will enable us to know the height socket , switches and tye DB

- Request for the plastering gauge

- Do the 1m level throughout the wall to have uniform height for all the accessories

-Mark out the position of our boxes,

Increment in Price of Electrical Cables

Has anyone here considered running wires for low voltage lighting in their project?

cc: Topsy23

I haven't ooo, DC cable is going to be needed for low voltage wiring. We call I direct current, if you are to use alternating current on the DC cable that means you have to buy a stepdown equipment that will convert alternating current to Direct current.

I have done some installation before designed in USA. Most of the cable recommended in the design are bigger size . We study the design and localise it with what is obtainable in Nigeria.

We cahnge all the cable size and and I was opportune to talked to the US consultants.

n3xt:
Congrats Topsy23!

Thanks boss

KolaShangOne:
Isn't this gonna work same as those CB switches on the DB? Only that this time, you'd don't have to open the DB to control them.

This is different from circuit breaker. This is a switch. Circuit breaker is to protecting your appliances

EgunMogaji2:
This is interesting. But the wiring has to have been considered from inception.

Yes we considered the wiring from the conduit stage . It's nice in the kitchen, open office and also in the event hall.

Gentle reminder for those that are in cabling stage

EgunMogaji2:
Oga, please explain more if you can. It sounds like safety thing.

PS: This I want to learn and maybe copy

Oga mi below is the sample of grid switch recently installed for a client in Lekki, We introduce it to him and he love it. We have all the sockets, Cooker control unit, cooker hood, AC and water heater connected to the grid switch, all the appliances have a central switching. Each knob have different rating from 10A, 20A and 45A

10A is controlling the lighting
20A controlling the AC, Water heater, Socket
45A for cooker unit.

Your kitchen equipment will determine the number of ways to be installed

The reason why we have 12 ways installed for this client is because:

1 knob for Light
5nos. of 13A socket connected
1no AC connected
1no Water heater connected
1no cooker unit connected
1no cooker hood connected

Total appliance connected is 10
The remaining 2 knob serves as spares

rotecch77:
We are constructing same on this project.
8 kitchens

Watch out
Work is in progress .

Edit
———-
This particular pics is a mini flat kitchen, we have 4 units of it and 4 units of 2 bedrooms flat in this building.
The 2 bedrooms kitchen are bigger in size than this .

More pics later as we progresses

Oga rotech, tell the client to have a grid switch for all the equipment in the kitchen. Let them have a central control.

spyder880:
You guys should sign Thierry Henry again as the central striker

Afterall he was the last best scorer in the club.

.or Kanu Nwakwo

BIGGIE121:
Sorry oo do they give notification for decrement in price too, cause na only increment own we dey always see.

Boss in Nigeria anything that goes up hardly come down
.

twinskenny:
yes o I heard Coleman price has increased too

No they haven't but likely to be towards ending of next week

There’s still hope

We have not fix the problem on ground

Hello ooo

abuiltech:
This is ok, but we will still need to look at other factors, ACCESSIBILITY, CIRCULATION & CONGESTION WITHIN THOSE MARKED POINT(BLUE), ALSO WITH THIS LAYOUT THE BASIN HAS BEEN CONFINED, ONLY IN WC(TOILET ) MIGHT BE THE ONE THAT WILL FIND IT USEFUL

You are right , accessibility is another factor. Also the orientation of the bathroom with enclosing the WC will create more space

Rexology:
Is this job well done by the electrician?

This look too busy and clumsy.

We have done this in the past

Below is our past installation

Mykel51:
Hello Engrs

I have a proposed building with a span of about 50m, a terrace building containing six units of flats. The proposed foundation system is raft beam with wide strip. What is the best way to introduce an expansion joint in the structure ?

That's a very big project

Good evening to everyone

QSFemi:
My final note on the QS and engineers rivalry as regards costing of some engineering developments.

First of all, I raised this issue so that clients and citizens can be aware of the current situation of things between the two professions. Both engineers and QS already know this since time immemorial.

The role of QS is non disputable in the building construction industry. The resistance QS is facing is in other areas of engineering developments that I've already highlighted in most of my previous posts.

The goal of specialisation and development of a profession transcends earning a living from it, rather, it's a means towards national development - which should be the focus of any well meaning citizen.

Nigeria is currently a developing country and with lots of infrastructure gaps to be put in place to meet her teeming populations. As of now, Nigeria cannot boast of steady and uninterrupted power supply, homegrown automobile industry, homegrown advanced and mechanized crop production for food security, sustainable and cost effective road construction technology, inadequate railing system and myriads of other infrastructure problems. In a nutshell, Nigeria is bedeviled with unsolved engineering problems. Compared to medical profession in Nigeria, home trained doctors, pharmacists, nurses, medical laboratory scientists and other related health workers have been fully managing the health of Nigerians since time immemorial. In Nigeria of today, the engineering profession is the most proliferated by expatriates just to fill the vacuum of technical know how that our home trained engineers are lacking. What a pity!

Come to think of it, I see no serious researches in this area by our all knowing engineers to solve these problems to make life easy for a common man. Please do not get me started on lack of funding or political will to meet these challenges. In Nigeria tertiary institutions, there are lots of professors of engineering in virtually all fields of engineering practised in this country. You begin to wonder, what novel innovations have earned them this highly prestigious academic status without corresponding research outputs for national developments. These scholars are highly funded through TETFUND, grants etc. The point I am making here is that the vast numerous engineering problems in the country are so great that the engineering body in the country should rather be too busy finding lasting solutions to them rather than encroaching into other professions. QS is not the only body having problems with them. So also is Estate Surveyors and Valuers who are contending with engineers on valuation of plants, machinery and other engineering developments for whatever purpose.

To my audience, the matter between the engineers and QS as regards costing of engineering works is already subjudice (the case is already in court) so that the court can interpret the act of the National Assembly establishing the two professions. You know in law, you cannot argue a case in public that is already ongoing in court. I only brought it up here for educational purpose.

May Nigeria win all her battles.

Well understood boss, Nobody is saying QS role is not important in building services. i have so many of them as friend and we learn from each other.

i bought the attached book for my own personal use. This book is for QS and engineers, I have read it and it really helps alot. The problem in Nigeria is that most people don't normal practice.

Barrmary:
Bosses please help me and access this quotation i got from an electrician for only the ground floor of a 2bedroom and 3bedroom flat in a 2-storey building.

Please I would need all advices on the type of good wiring to use for steps to follow when wiring a building because I believe wiring is one of the most important aspect of any building.

It's a rented flat but i would need good wires to buy that would last very long with good durability.

He said the Labour charge is negotiable and the cost of the pipe is the bendable one for conduit, he said the boxes can stand the test of time and the distribution box is the second grade.


Please I need your inputs on this!!!!

The price of the pipes looks like niger pipe. I guess this is not Lagos,
