An Analysis of the Methods for Measuring Construction Productivity

It is widely accepted that productivity measurement plays an important role in the construction management process. Productivity measurement provides the necessary data for managers to control construction progress and estimate the cost of future construction projects.

It has been appropriately stated that an accurate measurement of productivity provides construction managers with a means of controlling their project by:

1. Determining how effectively their projects are being managed
2. Determining adverse trends quickly so as to facilitate timely corrective action
3. Determining the effects of changed methods or conditions
4. Identifying the reasons for differences in productivity from one project to the next
5. Providing the means for assessing the effects of productivity improvement programs

Productivity measurement plays an equally important role in estimating the cost of future construction projects. The measurement of productivity from past jobs is probably the single best source of information for estimating future project costs.
