The secondary sector of the economy or industrial sector includes those economic sectors that create a finished, tangible product: production and construction.
Industrial construction, though a relatively small part of the entire construction industry, is a very important component. Owners of these projects are usually large, for-profit, industrial corporations. These corporations can be found in such industries as Infrastructure, Power Transmission & Distribution, metallurgical and material handling, medicine, petroleum, chemical, power generation, manufacturing etc. Processes in these industries require highly specialized expertise in planning, cost estimating, design, and construction. As in building and heavy/highway construction, this type of construction requires a team of individuals to ensure a successful project often undertaken by big construction companies.
