Abstract: The investigation of soil properties is vital in determining causes of building collapse in Nigeria today, but most times the geotechnical tests and analysis are neglected and site engineers are held responsible for the collapse. This paper seeks to investigate the soil properties of a collapse building site in order to emphasize the need for a geo-technical investigation as a vital tool in the built environment. Investigation of soil properties which includes sieve analysis, moisture content, specific gravity, Atterberg limits and shear strength were conducted on samples collected from the site. Two foundation bases were exposed (Base and Trial pits). Disturbed and undisturbed samples labeled Sample 1/1, Sample 2/1 and Sample 2/2 and recorded as Base 1, Trial pit 3 and Trial pit respectively were collected at the foundation depths of the exposed foundations by driving the sampler at various depths of 0.8m, 0.8m and 0.5m and tested. The soil’s silty nature and low bearing capacity of 36.37KN/m2 as the investigation revealed was a major cause of the collapse and that the building collapse site was a made-up ground. There was no geo-technical investigation prior to the building construction. Other causes such as the used of sub-standard materials, poor construction quality, quackery and supervision boils down to the lack of soil investigation which has caused the building foundation to fail and has resulted to the collapse of the building.
