I'm struggling to understand you a bit.But I shall try my best.there are basic tools of the trade and there are pro tool.things like cement mixers are basics cos they have three parts engine .drum and gear.the engine is same as ur generator.the gears has your usual cogs. So its meant to be same maintanance cost as the humble generator in this case same as I pass my neighbour. If I was a Co tractor I will buy one of these N150k will land one frm the UK. To rent it in a day is N10. U can mix concrete and cement for rendering aka plastering.mix mortem for laying of brick.I will like to emphasise here that using this 15 times in diff days pays of the over head cost..
Now let's go to soil compactor. Cost brand new £300.might cost £159 to ship.this is at brand new.so landng price say N180k. Rental in a day approx N8. 20 times of usage pays it off.Go to the concrete poker it's even cheaper £110.All these machine has btw 3.5 hp and 5.5 hp ho da Engines so they use same parts as yoy petrol generator.So just imagine if U can remove all these cost frm the bills of your clients would t they be happy?plus your work will be professional.

To be frank, concrete mixers, compactors, levelling instrument, pulley system, filling machine, sprayer, excavators and other specialized equipment should be basic in running of a small building construction film.

We hardly built to specification due to lack of simple tools that can easily be sourced.

I will be looking at acquiring some of these tools in the near future

Hello everybody...pls i want to know how big is a land of 580sq meters..is it up to a full plot? Thanks

A plot of 60ft x 120ft (18.29m x 36.58m) is around 669sqm
A plot of 50ft x 100ft (15.24m x 30.48m) is around 465sqm

So yours is in-between, a little bigger than 50x100ft Plot. So you can say it's a full plot based on the above.

Hmmm @ segcymoor u hit that nail for head. Unemployment oooo. Hunger go kill people for this one.

I don't really think that will leads to massive unemployment. I am of the opinion that more jobs can be generated from adaptation of specialized tools in building construction.

For example, company can be set up that specialized in concrete batching, using mobile mixers with pump to deliver ready made mix at required strength to sit at an affordable price. each of these company will employ engineers, operators, drivers, material scientist etc. These will create high end job for the population.

Adaptation of these technology will create also create opportunities for mechanics, fabricators and others that can replicate Chinese, German models, in other to produce cheaper alternative, which automatically leads to job creation and technology transfers.

The bigger picture is the housing needs for Nigerians, we need millions of building unit every year to meet up with our big population. we need materials to build up our infrastructure gap etc.

From my travels around Europe, I have noticed that foundations and columns of buildings are heavily fortified. After that, the upper floor decking and walls are usually built with as light a material as you can have. Mostly hardwood, cardboard, glass and very light concrete walls separated by long and wide glass windows. So why is it that in Nigeria upper floor decking is expected to be at least 6 inches thick with all that iron rods, cement and concrete?
My question to builders and experts here is this: Is it not possible as well safe to build a decking of 3 or 4 inch in Nigeria as well as use light materials for the upper floor?. I really think that Nigerian builders overload the foundation and columns in a house by placing very heavy construction materials on top. I remember very well that the upper floor deck of my secondary school AD block was made of nothing but wood. It was built by the British. Building stands till today.
In light of what I mentioned above, I would like to come in contact with a builder who can construct my on going project in Lagos on those terms. The building has been built to Lintel level with heavy foundation and extra columns. I do not want to overload it. I personally do not think it's safe to do that. I need suggestions and opinions here.

Sir, will you please stop making sense?

Are you really a builder? In Nigeria? I can't believe it.

You have an exceptional grasp of the economics of industrialization which directly applies to the home building industry.

Oh boo hoo...so the Iya Oniyas that are running buckets of concrete up and down the rickety stairs to build deckings will be out of jobs? I say good. They won't miss that if they can be retrained as Concrete Truck drivers, Concrete pump operators, Site Supervisors, etc

For sure. And a member on here, ChinoSXL, ships out of Texas really cheap. Even has door to door hookups.

Anyone can just place an order on eBay, or anywhere and use Chinos USA address for delivery and he'll take care of the rest.

There are many that can do the work for you but if I were doing the build I would check with this builder on this thread

I have said these things here many time. It is called overbuilding. Too many unnecessary columns/pillars, chained lintel, German Floor......

At the end, the finishing is nothing to write home about.

The house I currently live in is a brick home with no single lintel, German floor or concrete beam.

I'm your witness Sir

I am doing pillars as recommended by my Architect because 1) in case of lawsuit once the building was not built as specified then all bets are off and 2) I have little trust that the blocks are made to the required strength.

Hmm! I cannot agree any less. My post in 2013 below https://www.nairaland.com/1338637/chateau-ile-oluji-construction-journal#16519897

But some clients be like I need raft, German/England floor, 40ft roofing kingpost, chained-lintels, pillars at every angles etc

We tend to overbuild and overspend on projects.

I think structurally U might have missed some point,apart from steel based structures, teh concrete structures are actually heavier .take for example a high rise complex with concrete structures and base.These have whole side walls built with concrete.I h ave one near me and everything is concrete I will take foto 2morrow

On what you are saying I will agree to some extent, I think there should be a weight formula to determine where and how support ie pillars and column should be placed.I think there should be a way of builders to calculate stress and where to relieve these stress in terms of pillars.it should not be a guess work

Here's a typical example:

Have you ever seen a chained-lintel in any high rise building? Have you ever seen it specified in most structural drawings? We tend to build as the "spirit leads." Why must partitions be block wall? Aren't there alternative building materials?

If a high-rise building can ignore this, why should it be compulsory for small residential building?

Nop there aint non however those slabs are 9 inch thick, with min of 18mm rebars inside, the glass panels are doubled in some places and are 1 inch thick.These structures are very rigid and knitted together.have a look at those slabs, that's what they use here now for high rise building with metal carcass structure.

We cannot compare high rise design to a typical 2 or 3 stories building.

EgunMogaji:
We cannot compare high rise design to a typical 2 or 3 stories building.

My point, and with those tall buildings, they have up to 30 feet deep piles

Why can't we compare them? I'm still talking about chained-lintels now. How is it different in both construction?

Most residential builds in my part of the country now have raft foundations.

To start with, a lintel is a horizontal member which is placed across an opening to support the portion of the structure above it. And it can be wood, steel, stone, brick or reinforced concrete.

So, whether high rise or medium scale development or a backyard project, any structural member placed over the doors and the windows is called lintel. Why is it always different in residential build? Why must it always be reinforced concrete?

The Usual Excuses! Blocks are not always strong. It bind the house together. It prevents crack. It prevents snakes from having access into the house through the block hollow space. (Don't mind me, I made that up)

What about the damage it does to our pocket? The imposed load on structure. How it makes redevelopment nearly impossible without tear down.

ahah seriously have you come to close contact wit what the call block or brick abroad? if you did you will know that this thing we call block in 9ja a typical exaple is making block with sandust or what they call it,the blocks here are always 4inch

Yes I think every little change to be constructed should first be calculated, drawn, approved before being implemented on site.

I've been a long term proponent of other than concrete lintels on here. We can use steel for lintel. Heck wood can be used on small spans.

The lack of strength of local blocks, some not all, is real.

seriously I lough at times, those block wont hold your house no matter what anybody tells me,you need those lintels to hold it together if not cracks will evolve until we spend money in improving the quality of the block

Talking about overbuilding or imposing so much weight on foundations, I talked about the use of clay pots in my other thread and wanted Hajj Mufutau to volunteer his project for a residential test-run but FEAR FACTOR and Hajj pulled out.

Most home owners are afraid to try new methods and techniques.. I know EgunMogaji will disagree but its true. Its not their fault though because quacks abound and there's no punishment for failure or even killing people by a collapsed building.

Case of the Popular church that killed over 100 people. Both the. church owner and contractor are still walking free till today.

This is the era of change.. so new, practicable ideas are always welcome.

True. Quality of blocks need to improve. That's why I bought a block making machine as part of my equipments.. I started making just 30blocks per bag and had to pay more for sand from Bakoto. But it was expensive. The client couldn't afford it all through..

one day client called me and said "for the next building we are going to do, I will like to buy Ogo Oluwa blocks at 140". I just smiled and said OKay sir..

erico2k2:

Granted I don't know as much as most folks on here but this is what I know:

Unless I'm onsite and supervising the block making mixture then I simply cannot trust the strength of the blocks. That's if I can even trust the cement mixture itself - groaaan.

I'll rather spend the money now than later after I've moved in and all my shyte is in there.
