Nice work, but this is not fix practices in some cases filing the blocks with weak concrete, laying of bolders or hardcores maybe adapt and shoring of excavated trench to avoid collapse. I major in marine / deep foundations and shoreline protection, thank.

abdulwastecx:


send the drawing to my mail so i can help with the estimates

don't have any. Want to know what its take

yes sir...you are right sir

Good work

I think you will have to lay your DPM after compaction before you make your blinding.

hurricaneChris:
Op good work u have done here. Please don't forget to let us know the challenges u faced while on this project.

ok sir

pls i'ld also like to know what is the estimated total cost for a foundation of 5Bedroom bungallow on a dry land.?

he's quoting for bungalow! pls don't derail a beg

send me the drawing

lol I have read through your writeup and found out that your end cost is even'higher compare to your aim(less cost) of writing.

Most of the cost you implore are paper work which when you get to site you will meet a different approach.

But thump up anyway.
@buildertwist.

Add me up on my bbm 296B4C2E. We need to talk as soon as possible. Or whatsapp on 07037409406

Thank you for a job well analysed. Pls what is the estimated cost of building a moderately spacious 4 Bedroom bungalow in a dry land. With land already acquired in a place like lokoja. Thank you.

Really appreciate your good work Mr Abdul and all others that shared information on this page...Trust me I really learnt a lot.

If the cost of survey is this cheap, then I was misinformed.. Thanks for the thread.

lokoja is a very good location to build a very cheap and affordable house, i bet you the cost will be minimal....i will need you architectural designs to help you with a figure

Pls can you send this analysis to my e-mail this is highly educative thanks akumetue@gmail.com.

Could you also please send this beautiful analysis to my inbox- Olu.olumide@hotmail.co.uk
Thanks

I'm very intersted to know this as well. Just about to start some thing similar. Thanks @op

Can i build a decent 4 bedroom duplex on half plot of land measured 50 by 50?

Yes, you can, i have a design of a 4 bedroom duplex with length 11m(36feet) x breadth 9.6m(32feet) and it is being constructed at benin.

Madam... this is relative topic of discussion. I am not a surveyor but building leveling can also be done by a civil engineer ( see engineering surveying), All these quotes here are for relatively small building work of say two bedroom to three bedroom flats.

The survey aspect of ur quotation is absolutely wrong n misleading.
U expect ppl 2 just give a surveyor 20k for his services n 10k for theodolite?

U only tell ur client d cost of survey per plot. Also, d cost depends on d location. If it's 70k per plot, it covers d amount 2 hire d survey equipments (theodolite/level, gps,tape etc.), transportation, labor, printing n signing.
There's a fixed cost for it depending on the state where d site is located.

I'm not trying 2 spoil ur market but most of our structural engineers know nothing about surveying.

If it's just levelling, will u tell ur client 2 hire equipments for u?
It's a professional job n not a bricklayer's job

abdulwastecx:


1: 3: 6 is weaker than 1: 2: 4 or 1: 2: 4 is stronger than 1: 3: 6, The difference between the two is just the cement content and the ratio of aggregates.

we are talking about a bungalow where the load on the structure are not that critical, hence a well placed concrete of 1: 3: 6 will do the work sufficiently.

The problem now is we don't even follow these ratios because of inadequate concrete production mechanism like batching plant.

pls don't generalise. I follow concrete specification n if u say a mix ratio of 1:3:6 is weak concrete, I guess u av to go back to the drawing board. U can't tell me a concrete mix of 1:3:6 is weak, even when Lagos state material testing lab comes to site during concrete casting, they advice 1:3:6 for reinforced concrete, 1 of the best company having much jobs @ hand is cappa n d'alberto, pls try n check their concrete mix.

@Abdulwastecx, I sent you an email please do find time to reply me. Thanks for your time

@OP ... Good work .

However , I for one , I don't take engineering theory serious . Out there in the field , before you will finish this theory epistle , an informally educated mason ( brick layer ) cum contractor would give you a structurally sound standing and lasting building . I doff my hat for the informally educated brick layers cum contractors in the building sector . This is my experience and opinion , therefore I don't owe anyone an apology .

The reason way we are faced with collapse buildings everywhere

i am not saying is weak but it is weaker than 1:2:4

i am not saying 1:3:6 is weak but 1:3:6 is weaker than 1:2:4 than since 1:2:4 has more cement and lesser other aggregates than 1:3:6

there is no market here to spoil madam. i did about three courses in engineering survey which i had A's in all of them, the least i could do is to carry out a levelling operation of a bungalow on a plot of 15m x 30m.

i believe no client in his right senses will pay you 70k to carry out a levelling operation for him.

Please let us be straight forward in our trying to tear down abdulwastecx's approach. It's not alright to get things twisted for ones own gain.
Some contractors are very dishonest; if you're not, don't be scared of his honest and cost saving analysis.

thank you my brother.... what people don't get is we have about 20m building deficiency in a country of more than 170million people, population growth of 5% and per capital income of $3,000 (N600,000), the best one can do is to build for these low to middle income earners.

We are looking at more ways and ideas on how to reduced cost further, so that an average Nigeria can afford to live in a decent accommodation instead of all the slum we find our self.
Bamboo, polystyrene, clay etc are the future of home builder and material engineers.

People want too much money all in the name of professionals, don't let people rip you of your had earn money

abdulwastecx:
I will start here explaining each of the steps listed below with simple arithmetic calculations of equilibrium, cost and with pictorial view of work done in the past.

What is site clearance: in a simple language, it is the removal of bushes, trees, and all other unwanted structures or material on site. materials such as site dump, unwanted sand or gravel etc. It also involved the removal of top vegetable soil of at least 150mm deep into the ground in other to allow for work to be done a solid surface.

How can site clearance be done:
There are two ways in which it can be done, namely;
1. Mechanical ways
2. Manually

1. mechanically: by using a grader to remove this unwanted site materials. This method is faster and cost effective over a large area of building land. I mostly recommend this type clearance for a big to medium project of 1 plot ( 50' x 100 or 15m x 30m) and above.
Most client are scared to use this method because of the perceived cost implication but in reality it offers more values for money because of the following advantages.

1. It offers wider coverage of work over a shot period of time.
2. It help to grade site uniformly, make access road to site and help to get rid of vegetable soil of 150mm above ground level.
3. Condemned soil from top soil removal can further be used to filled the foundation where laterite or other feeling materials are expensive.

Cost implication:
It cost about N60,000 - N80,000 to get a grader in Port harcourt
it cost about N30,000 - N 50,000 to get the vehicle that will bring it to site.
fuel cost of about N20,000
Total of = N110,000 ( minimun)
Total of = N 150,000 ( maximum)

2. manual method: This involve the used of crude implement like cutlass, hoe, rake and shovel to remove the bushes, unwanted materials and top vegetable soil of a building construction site.
This method is cost effective over a small area of land like half a plot for a 2 bedroom or 1 bedroom flat. It is cheaper and more labour intensive than the mechanical method. it is recommended for a small building project like a two bedroom or one bedroom flat on half a plot of land.
It cost about N20,000 or less to prepared a land for two bedroom flat bungalow using this method.

Am about doing a 4bedroom bungalow in a relatively flat ground,do I still need to do mechanical clearing?
