Hello Guys,

I've been following Nairaland as a guest for a while now, but this is my first time of creating a thread.

I'm about constructing a 3-bedroom flat en-suite on a half-plot of land located in an area where plaster sand (called Dagbolu) had been excavated. However, my concern is how to go about the foundation, as I noticed that the the area that my bricklayer had dug became water-logged and almost got washed off as soon as it rained, which gives me the impression that the foundation would need more reinforcement than normal.

Therefore, I need to know the following:

a.) How to go about laying the foundation

b.) What materials would be needed in laying the foundation

c.) How much it would cost to lay the foundation according the method(s) suggested in (a) above and considering the materials suggested in (b) above

d.) How much the whole construction from foundation to roofing would cost considering the nature of the land and the building plan

Please find below pictures of the little work done on the land, as well as the building plan. The land is located in Oluodo area in Ikorodu, Lagos.

Expert opinion would be highly appreciated.
