Hello Abdulwastecx, I found out that some people don't add floor beam in their slab.
They would rather do lintels through the entire perimeter of the house. How safe is it?

this is very unsafe practice. when we build suspended floors we assumed that our building is frame hence the block wall are non load bearer.

the strength of our sancrete block at maximum is 4N/mm2 coompared to concrete strength of minimum 20N/mm2. Most blocks sold commercially in Nigeria has lower strength of between 0.5 - 1.5N/mm2, hence it always better to build any high rise building as a frame where partion walls don't carry load

the building you just posted above sir, will most llikely collapsed in the near future leading to lost of life and properties

Pls what does 1.25 stand for?

1.25 means 25% increase, an allowance for losses, shrinkage, wastage etc

do you need these men to affirm your fate.religion is a personal thing, the moment we realized this the better for us and the less money for these entrepreneur pastors

yes you can

I have witnessed it here that they use more sharp-sand and cement more than we do in Nigeria. The ratio of sharp sand or stone dust to granite is like 2:1. The amount of cement they use here is unprecedented. That enables it to look well done when finished. In Nigeria, we tend to use a lot of granite.

actually concrete are made with different mix ratio, size of aggregates and water to cement depending on what property we are looking for.
concrete is a composite material of cement, aggregates ( coarse and fine aggregates), water and sometimes pozolanic materials etc. cement act as a binder when mixed with water to bind the aggregates together. coarse aggregates ( gravel) is responsible for the strength while fine aggregates help to fill the void space between the gravel since gravel are of irregular shape, fine aggregates also help to increase the volume of concrete.

most mix ratio are are design based on the above principle, that i the reason we normally have coarse aggregates ( gravel) in our concrete. examples includes, 1:2:4 ( one bag of cement:four head pan of sand and eight head pan of gravel) or 1:3:6

Great job, sir.

thank sir

Very true to some extent. I have witnessed the way they apply water to concrete in the U.S and the water they apply is not much and the concrete always come out great.

Can you explain to me why when we do concrete in Nigeria, we tend not to spend time making it look well finished like the ones in the pictures below? Anytime I see concrete shown on nairaland and I wonder why more time is not spent making the concrete look very nice like it is done in other countries. Can you compare these concrete pictures to the one we do in Nigeria?

I wrote vib.rat.or not romance machine.
as regard to those pictures below, there are more fine aggregate ( sand) than coarse aggregate ( gravel) because of the intended uses.

As can be seen, the concrete used as floor screeding.
method of concrete production also play an important role in the strength and appearance of concrete. In developed society, concretes are mostly produced in a batching plant where all the parameters like mix ratio, water to cement ratio, finest of aggregate, conditions of aggregate, quality of water are controlled. In Nigeria, concrete are manually mixed using hand or a concrete mixer, the result been that quality and quantity of cement constituents are not well cintrolled.

size of gravel also affect the appearance of concrete
ratio of cement

things like clay in sand or gravel,
dirty water
very high water in concrete, result to considerable lost of strength.

workmanship is another factor, skilled concreters are lacking in Nigeria and the formwork here are not as good as what is obtainable in the west

irokop:
But oga engineer it looks as if the mixture of the concrete is too dry, I think it's supposed to be a little bit watery pls I stand to be corrected ooo.

we actually make our concrete too wet in Nigeria because of our method of placing concrete, which is done manuAlly most times.
water to cement ratio of 0.55 is ideal nut due to workability of concrete we tends to put more water....from research, the more the quantity of water the weaker the concrete and that is why you need a vibrator to help the concrete work very well

Building is by doing.

A lot of people see building as a business. Architects, civil engineers, building technologists as well as building enthusiasts all build. A technogist with experience is better than an Architect or Civil engineer without. My civil engineering friend will say, " if I take you to site, you will learn ". After school, one doesn't start building no matter what he studied. Hands on experience is what counts.

You won't know what a man studied until he decides to tell you. You don't need a quantity surveyor before costing a building..

I started going to site as a carpenter and a site supervisor for my building technologist father.
Naturally, I developed very good understanding of both metric and empirical measurement, estimation of materials, and interpretation of building plans.

I got admitted to the university after four years of extensive site work. working with very experienced artisans like iron benders, masons, carpenters etc. I also learn a great deal from professionals like architects andd building technologies etc.

I did study civil enginering because of my mathematical strength. I graduated with a first class degree from FUT minna and I love building and structures as well

you are on point sir

shaokhan01:
quack engineers.... you don't even ask for the length and width of the building..... your extimation is totally wrong.

what estimation are you talking about?

Mushood:
u tried in ur estimate but u made some mistakes in which hype d amount higher. Wen u are estimating for d concrete in foundation strip, u use 0.1mx0.45mx230mm which is wrong and again, u got d thickness rite, d width rite and d length wrongly. Recheck

I rechecked the calculations and saw nothing

gmacnoms:
in layman's term abeg. Na im b hw many blocks high?

ten feet high...like ten block from ground level and 3 block inside the foundation

LLVelly:
guy na step by step tinz, u don't need to estimate coz all u'll see is discouragement, no matter ur estimate u must still over spend ur estimate, clearing of bush + cutting of trees are also inclusive,so just one step at a time u'll excel. May God help+protect you.SUCCESS.

proper planning help to reduce wastage.

Justcul:
Can a 50x100 plot of land contain 2 bedroom flats (x4)?

Thanks in advance.

very adequate

Bwaal:
re u on watapp can u pls qoute me ur number

08169492682

kuntash:
3-flats of Two bedroom flat each... would sit comfortably on a 50ft by 100ft with a parking space

nice idea! its like hotcake now... lol

@Abdulwastecx ... do you have a thread/project that matches this description on-going?

yes i do have a proposed project that matched your description... i will send a sketch to soon

gulfer:
@ abdulwastec, could you please tell me how much it will cost to put a fence round 2 plots of land (100*100). Thanks for the anticipated response.

assumptions:
height of fence = 3m (10')
depth of fence foundation = 600mm ( 2')

total height of wall = 3.2m

perimeter of a 100ft x 100ft (30m x 30m) = (2 x 30) + (2 x 30) = 120m

excavation of foundation @ N300/m = 120 x 30 = N36,000

blinding/footing to fence = 120 x 0.1 x 0.625 = 7.5m3
using mix ratio of 1:3:6;
part of cement = 7.5 x 1506 x 1/10 x 1/50 = 25bags @ N2000/bags = N50,000
part of sand = 3/10 x 7.5 x 1.6 = 4 tonnes @ N1600/tonne = N6,400
part of gravel = 6/10 x 7.5 x 2.4 = 12tonnes @ N8000/tonnes = N96,000
workmanship for concreting = N20,000


block work:
blocks required = perimeter x total height x percentage increase of 30% = 120 x 3.2 x 1.3 = 499.2m2
Quantity of block = 499.2 x 10 = 4992 blocks @ N150/9"block = N750,000
cement for the block work = 70bags @ N2000 = N140,000
sand for the block work = 11/2 trip @ N30,000/trip = N45,000
workmanship for block work @ N50/block = 5000 x 60 = N250,000

Total = 1.4million

Nwa4Jesus:
nice one. But it depends on d area blc my area blocks 6" is at d rate of 150per block. Sand 45,000. Grante is something else. Weldone

sharp sand @ N1600 is fairly adequate, since 30tonnes will cost about = 30 x 1600 = N48, 000

sheunflexy:
Bro in as much as I repect peoples opinion,all the estimation giving to you are just rough estimation.1,before any estimatoin u have to know the total area of the structure.2,which state or area do you intend to errect the structure,materials varies with each state eg,30 tones of chipping in ph city cost #280k,am sure it can never be the same with lag,so all this have to be put into consideration first.

it actually cost between #180 to # 220k in port harcourt.

I make assumptions based in some set parameters. it is easier to make assumption base on a bungalow not matter the.site conditions ( except for a swampy area).

All estimate here are provisional amounts

[quote author=imoci post=31037348][/quote]density of sharp sand = 1600kg/m3
since to convert to tonne, 1tonne = 1000kg

density of gravel = 2400kg/m3

density of cement = 1506kg/m3

1600/1000 = 1.6tonnes/m3

2400/1000 = 2.4tonnes/m3
