The Construction Industry Value Chain

The construction industry is a very important one. Globally the annual value of the construction industry is of the order of 1. 5 trillion dollars constituting about 8% of GDP and about 60% of fixed capital formation. It is one of the most relevant forces of the world economy representing 7% of its total employment. In Kenya and in Tanzania, the construction industry is a key indicator and driver of economic activity and wealth creation

The construction sector involves the construction of a wide range of public and private sector facilities including but not limited to: Transport and communications sector – roads and public works, bridges, airports and sea-ports, telecommunications systems, etc Water and sanitation projects- dams, portable water schemes, sewage schemes, irrigation systems, etc Energy – Power stations, power transmission lines, renewable energy schemes, etc

Buildings- Residential buildings and estates, slum redevelopment, hospitals, schools and other educational facilities, hotels and touristic facilities, factories, shops and other commercial and industrial facilities Thus the output of the construction industry has a profound impact on our lives: the homes and offices we live and work in, the transport systems that we use to travel, the water we drink, and the electricity that makes our lives bearable.
