Cindy & Tram Consult have approached you with a design brief. They want to construct an Estate in Lekki area of Lagos State. Write a case study on the best choice of
foundation you would recommend, stating clearly reasons why you are making this
recommendation. The building is 5 storeys high; Lekki is a waterlogged/swampy area.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
