Construction industry is an essential instrument of socioeconomic
development of any country. Indeed in every sector of
the economy, there is a component of construction. For example
in the health and education sectors, hospitals and schools are
constructed; in transport sector, roads, railways, harbours and
airports are built to move both people and goods; for various
manufacturing and industrial establishments, factories and
warehouses are erected.

All these represent significant features
and support so many socio-economic
activities that the construction sector can be described as the
backbone of development (UNCHS, 1986: 3).
