Productivity in Construction Projects

Productivity is one of the most important factors affecting the overall performance of any construction site, large or small. There is no standard way to define productivity for construction operations. In general terms, construction productivity can be simply illustrated by an association between an output and an input. As such it would be worthwhile to study various quantitative methods, including construction productivity measurements for reason of:

i. Decreased total cost and duration of production.
ii. Improved quality.
iii. Providing management with an effective tool to direct and control the productivity performance of a construction site.
iv. Offering feedback to employees on their productivity performance.
v. Creating the basis for sharing the gains of higher productivity. Productivity measurement at construction site level enables companies to monitor their own performance against their site performance. Construction productivity at construction site level can be grouped under various departments likes, productivity in concrete, steel work and shuttering



Type of Productivity
1. Single factor productivity. Productivity calculated for single activity like labour, concrete or equipment is known as single factor productivity.

2. Multi factor productivity. Productivity calculated for more than one activity like labour and equipment or Material, labour & equipment and concrete is called multi factor productivity.

3. Total Factor productivity. Productivity calculations which include all the activity on the construction site is called as total factor productivity.


Measurement of productivity

Productivity for individual projects can be measured upon project completion or during construction. Productivity can be calculated on a monthly basis by estimating the floor area completed at the end of each month and dividing this figure by the total manpower used for that month.
