The determination of productivity index in construction process / Amlan Yunus

Labor productivity is defined as the input divided by the output, and is calculated for a finite time interval the following way: Labor Productivity = Manhours/Units of Work It is commonly called the unit rate. The need for a standardized approach for measuring construction task-level labor productivity has long been recognized. Furthermore it is known that before the factors affecting productivity can be studied, there needs to be a large data base containing information from many project constructed under a variety of conditions. This information must be uniformly collected from each project. The objective of this project is to describe a task level labor productivity measurement and performance evaluation system that can be used by owners, contractors, and subcontractors who presently do not have a formalized effort.
