Construction projects (activities) have some unique features with respect to other industrial projects. Some of the important features have been dealt with in subsequent paragraphs :
Complexity
The conventional image of construction is amalgamation of a series of manual and semi-manual activities. This concept is highly misleading. Construction projects, today, are high tech, highly mechanized and complex. A typical construction project is characterized by consumption of numerous types of materials, variety of tools, equipment, plants and machinery working in tandem, several different contracting agencies, big and small, sub-contractors, petty contractors, vendors and suppliers, area specialists, consultants, supervisors and managers, each with independent organisational set ups, participating with complex interactions, working in cooperation, sometimes even at cross purposes. In addition to these highly interactive and complex environment at construction site, thousands of activities each of different nature are arranged simultaneously, many of them, sequentially or at random. Thus, the construction project today is much more complex than any other production process, manufacturing or service industry.
