Project Productivity

Project productivity is defined as the amount of floor area completed per man day. The project productivity is calculated as follows:

This is consistent with the industry's method of measurement and is also in-line with the measurement of trade productivity which is defined as the amount of physical output per manhour.

A project is deemed to be more productive if more square meters of floor area can be constructed with the same mandays. In other words, the higher the figure, the better is the project productivity. Table 1a and 1b shows the project productivity of our local construction industry.

Please note that:

  1. 1 manday is defined as 1 man working for 8 hours.
  2. The project productivity shown in Table 1a and 1b applies to building projects only.
  3. The industry overall productivity indicator is derived based on the percentage of progress payment for the various building categories.
  4. The site management team is not included when calculating the total number of site workers.
  5. Only on-site works are considered when calculating the project productivity.
