The close relationship between design and construction is one that requires an integrated system, usually involving detailed plans and specifications. Carnegie Mellon recognizes construction planning is a process of identifying activities and resources required to make the design a physical reality. Construction, therefore, is the realization of a design put forth by architects and engineers. The various operational tasks that have to be performed in design and construction must be tracked throughout the project lifecycle.
The project lifecycle doesn’t end just at the completion of construction and occupation of the building; it extends many years beyond that. Since there are also many specialized and custom features to buildings, they can take many years to complete. Factors such as site, weather, building codes and other issues must be taken into consideration. It is difficult to foresee the needs of the building over its continued lifecycle. Design plans are changing throughout the lifecycle according to technological changes and the demands of the structure.
