Thanks. I plan to build a simple twin self contain house in half plot. I have a trusted bricklayer, do I need to get a contractor having known the process? I have time now.

U still need an advice of a professional, even if it's on consultancy level

For ur interior decoration like p.o.p and wall screeding. .
We Are always available

frank043:


Thanks. Are you a practicing structural engineer?

Practice as a site engineer not as a structural engineer ......... .
And am on my own.. .no company recruiting.. .
Search search tired.. ..

Excavation of the foundation trench cannot be over emphasized, no matter the method you adopt. Sometimes the clients too will tell the contractor to try and manage. I remember a renovation job I got 2011 when I've not had much years of working experience. It was a massive structure with swimming pool on a watter logged plots of land. After some years, there was a differential settlement even the walls of the pool collapsed due to the passive earth pressure, I was able to make a good retaining wall for the pool and hired a more experienced structural engineer to underpin the existing structure, yet the client was complaining about my bills but I treathened to quit before he later sucumbed. From my experience, I've seen that Clients also contribute to some of the structural failures.

U speak it all

I'm a Civil, Structural and Geo-structural Engineer... I'm working towards being an expert in these areas.

Nice one..

frank043:


Fair enough... But depth of excavation is a function of geotechnical report, which informs the engineer on the profiles of various soil bearing capacities with depth. One doesn't just choose to excavate or not. By the way, are you a structural or geo-structural engineer?

Structural engineer and you

frank043:


Really... You sounded more like a layman to me.

But u still understand the message am passing

frank043:


What do you mean by... 'you don't need to dig down'?

Excavation. ....
Layman word...
Don't want to go engineering

abdulwastecx:


I will have to agree with you here sir.
In Nigeria, anything different from the norm is deemed not suitable. you don't have to necessarily dig down place your foundation and depth of excavation depend on the position where you have a safe bearing capacity that will carry the building.

Raft foundation can be built on a sand filled site provided adequate measures have been taking to dewater, removal of vegetable top soil and very week soil strata at the top and adequate compaction (either through mechanical means using a roller in layers or by allowing the soil to consolidate under its own weight over a number of months or years.

Even on a land that seems stable and hard enough. You can't conclude until u carry out soil investigation. What is lying 500mm to 1000mm below NGL might surprise you during excavation.
Perhaps, short piles of about 4-5m have been introduced where considered fit economically

U can't just sit down concluded u want to use a pile of 4-5 m for residential building of 2 to 4 floor.. .
It depends on d load that's coming on d foundation that means u use pile.
Bridges Self dey use pile of 5m ,now talking of our common House.. .wetin he wan carry. ..pile of 1.2 m is okay if necessary

Sir, even when you're doing raft you still have to dig to depth that would contain it before any construction.

Not all situations...
Situation u bough a land in swampy area. U fill it and leave it for over a year to settle and need to a duplex on it.. .u don't need any digging, d ground is stable

COOLDK:


The main purpose of adopting a raft foundation is to prevent differential settlement.

Even if you are adopting a raft foundation, the technicality and logics shouldn't be compromised. You still need to carry out soil test/investigation to ascertain the suitability. Otherwise piling will be best here.

The argument here is not which is d best
But situation u cast a ground beam on Sand with digging is possible..

Piling are required in a waterlog area that u don't know the hard surface, so would drive the pile till u hit a good ground or hard surface because u can't say u want to use a pile on solid ground when u not constructing bridge

Well it depends on type of foundation you are using
If u are doing a raft foundation ,u don't need to dig down ,just make ur form work, reinforced it ,you are good to go, since d surrounding Is still going to be fill with sharp sand.

But in situations of hollow block.. ..dont try it

Really

Okay... . Happy Birthday

I want to build my septic and soakaway, but noticed that it has a low water bed. The plumber has just taken the best slope for the chambers by raising the pipes above the ground and the point of entry into the septic is quite low. Please I need suggestions.

Bro.. No cause for alarm, u don't need to worry..
All u need is pumping machine, a good Carpenter that can board in swampy area ,iron bender and u are good to go.. .
Make sure u use a marine board for easy work and 90% straightness

Okay....

Badgers14:


You are very funny... I had a high hope reading your response until i got to the bolded...

He is trying to minimized space.. .with that... He would require at least 2 stair

Sorry Bro.. .its ordinary mathematics

Unless the third flat would have separate stair

Badgers14:


The contractor is suggesting 2 flats on the ground level, 3 flats first and second floor then a pent house of 2 bdrm flat.

But my concern is, the stability of the house? I don't want to be a part of any house falling over.

What do you think on that?

Once D architect is abLe to sketch it out.. And u okay with it.. .u can go ahead it with it.. ..leave d rest for d structural engineer. .... And don't overcompromise on site

But don't know how 3 flat would b on 2 flat

Badgers14:


3 flats ground floor, 3 flats first floor and 3 flats second floor

It would b very hard sir

Badgers14:


Do you think a 2 storey 3 bedroom flat will fit fine on a 50x100x50x100 piece of land.?

Why not.. ..once ur space is being maximize well by the architect ....
How many flat on d ground floor

Frankgoz:


My brother where on earth is setting 10k in this country I will advice u not 2 mislead this woman. Is inly a one unit shop u can set out 4 dat price.

No mind some people.. ..they always compare a bricklayer work to an engineer.. .
If I go setting out for anybody.. .i collect at least 20k.. .. Unless my relationship with d person sha.. .

bebe2:


Location is opic estate , badagry express way, agbara axis.

It's a dry land. So regular upstairs foundation.

I think the blocks are too much, 2000 blocks to foundation?? How many blocks would then then finish the house?

And if iron bender is 18k a ton, am using 1/4 and 3/4 which is a total of 2tons approximately, which should be 18x2=36k , so why am I being charged almost 200k?

Will upload the plan

The block not much depends on how high ur foundation

thanks. my boom player is not responding, if I click on it,it will open half way and close again( as in, return back to ideal screen,where the icon is ) Did yours experience such?what can I do to over come it.

No.. ..
