mufutau55:
THANK YOU VERY MUCH SIR! (Yes in CAPS). Le't keep up the good work.

segcymoor: Hmmn. I am afraid

segcymoor: Anyway as scheduled we conduct the soil test and investigation as schedule and behold the result make me afraid because within the area was raft foundation done but I tell you the best and safe foundation to adopt for this particular project is nothing but PILE!
.....it was revealed that 1.2m we assume safe is not good enough. The safe bearing capacity for this site is 2.7m

cleric:
Hmmmm....this is interesting. So even an inverted "T" with broad base will not suffice? . We are talking lots of money here because I assume you will need a minimum of 9 pillars of pile.

segcymoor:
Absolutely! However, for that to work we need 2 options:
1-To excavate all building area with depth of 2.7m. So 2.7m in addition to 1.5m to road level. Odd!
2-To excavate all building area and back fill with sharp sand to natural ground level then proceed with normal 5 board.
However, any attempt to adopt any this option is to create a 'swimming pool' here because the water level here is quite high.

Hence the best and most safe and economic methods:short bore pile!

Chekitaut: await, i pray the client adopt the option...because many client(s) do not like to hear pile.

chimeg: @ Segcymoor,
Na Wao! This is quite some creative thinking.
So what will be the average cost of the pile foundation for this project?
And will it work perfectly well at the end?
Does it mean that the other houses standing in the area had pile foundations too?
Can you kindly respond please.

segcymoor:
And regarding cost implications . ordinarily piling is quite costly than raft. However, our client has limited budget so we are looking at how to do better foundation (piling) with figures not too far from initial quote. ........e no easy o

segcymoor:
In the first place, the most safe form of foundation is nothing but PILE ! How do you think bridges stand?
Although no building yet at both sides and back of the subject site. But from experience the land beside may have different texture. As a matter of fact raft is being done @ 2 plots to the side.

However, for clarity I may need to inform you that the texture for this particular site is not far from normal ajah sandy texture which ordinary raft will do.

Now, let me analysis what caused problem here:
From lekki epe express way towards the site was a sharp slope and the land level almost at the beginning of this subject site. From ages all the rubbles, rubbish etc was drawn down to this end by erosion over the years hence making top soil not good for structure. However underneath is sandy and firm soil.
if not for road level we intend to achieve and the fact that water level of this site is high (simply because it received all the water from higher ends to where it located underneath) we may easily remove all this stuff and do normal raft.

And regarding cost implications . ordinarily piling is quite costly than raft. However, our client has limited budget so we are looking at how to do better foundation (piling) with figures not too far from initial quote. ........e no easy o

cleric:

This is serious but in the end, one has to do what has to be done otherwise the options are to either sell the land or risk other peoples' life and the funds invested in the development the property because sooner or later, the lapses will begin to show.

segcymoor: Hmmn. I am afraid

Aventures: Following with keen interest

Jamesqu: Segun,
I was just waiting for you to come back with this information. Mere looking at the level of water your guys were attempting to drain immediately indicated that only piling would solve the problem.
I doubt there is such a thing as only one plot in an area having this charactersistic. The surface area of the sand migration in your analysis will not be deposited in only one plot...that is why we can have oil in Akwa_ibom as well as Ondo state. The migrated sand from the inner Niger River was deposit across a wide area covering lots of flora, fauna and micros. The two sites around you doing ordinary raft will find out the hard way.
Not to digress...let science lead you and not money, if the soil test indicate only piling will do...then attempting to improvise will create a problem in future years.
Advise your client to look for the money by showing and educating him of the consequences...BoL!

prince0011: Please Segcymoor, can you please provide me with the details of those that conducted your soil test? I hope to hear you soon.

segcymoor:
Your analysis is absolutely correct! Virtually no structure yet within the area but bush. However, 2 structures at the vicinity is about 70 feet away. One is Burgalow and uncompleted story building with raft foundation (although yet to receive load)
On the contrary, my client appreciate our professional input and ready to go for it. Unfortunately, he has a tight and limited budget. As it stand, we are at the edge of sacrifice our profit to make this foundation done properly. .......it may sound unreasonable to you!

Jamesqu:

Not at all, though it is unreasonable for a contractor to eat into his profit but it is not unreasonable for me to hear it from you .

Regards to madam and the little girl.
