Identification of Components of construction

Basic Principles 

In both the processes of measurement and pricing, the basic principle adopted is "deal with parts first; then combine the parts to form the whole" or "analysis" and "synthesis". Analysis is the separation of a thing into its constituent elements, and synthesis is the combination of such elements into a composite whole. In the analytically process, the building project requirements are divided into units of work, which are the various trade sections or distinct disciplines of work to be done; these units are further subdivided into items of work, which are the smallest individual portions of the various types of work that can be readily classified, measured, priced, and accounted for. In the synthetic process, predictions in the form of prices are made about productivity and costs of materials, labour, and machines : these prices are then applied to the measured quantities of work to produce the anticipated total cost of the project.
