ForewordThe Building and Construction Authority (BCA) formulated the Construction Productivity Roadmap in 2010 with the aim to transform the construction industry and raise its productivity. Under the key thrust of enhancing industry awareness, BCA was tasked to establish benchmark indicators especially at project and trade levels for builders to track their own productivity performance. In order to do this, it is necessary for builders to adopt a common methodology of measuring project and trade productivity. On 15 July 2011, the submission of construction productivity data to BCA became a mandatory requirement for the builders. This was in conjunction with the enhanced buildability framework and applied to projects with Gross Floor Area (GFA) of 5000 square meters or more. The builders used a common platform under the Electronic Productivity Submission System (ePSS) to submit the construction productivity data. These data would primarily be used to establish the project level productivity.
Apart from monitoring the project productivity of building projects, it is also necessary to measure the trade productivity to have an in-depth analysis of the productivity performance in various aspects of site work. Trade productivity would refl ect the effi ciency and the quality of the workforce. It is particularly useful for planning and scheduling of work processes. BCA has thus produced this Builders’ Guide on Measuring Productivity. This Guide provides best practices on how to measure productivity for the 12 key trades which are commonly found in most construction projects. These best practices are illustrated through fl owcharts and photographs that showed the activities involved in each trade. Productivity Monitoring Forms have also been developed for each of the key trade and builders would be able to adopt them as a common tool to measure the trade productivity.
BCA has been working closely with a group of builders in developing and using this Guide to study the trade productivity since February 2011. This Guide should come in handy to those who are unsure but want to start measuring the trade productivity in their projects. There is nothing better than learning from those that have embarked on and excelled in the same journey.

TIONIntroduction
The measurement of trade productivity provides the builders a platform to carry out in-depth analysis of their productivity performance. At the trade level, the amount of physical output per manhour is measured. A worker is deemed to be more productive if he produces more output within an hour. The indicator is calculated as follows:
The unit of measurement for trade productivity would vary for different trades. For example the unit of measurement for formwork installation is area of formwork installed (m2) / manhour while the unit of measurement for electrical conduit installation is length of conduit installed (m) / manhour.
This guidebook sets out the best practices on how to measure the productivity for the 12 key trades which are commonly found in most construction projects. The Productivity Monitoring Forms that have been developed for each of the key trades gave the activities and parameters that the builders should monitor and measure. Through these forms, the builders would be able to adopt a common platform to measure the trade productivity. To complement the forms, the activities involved in each trade are illustrated through fl owcharts and photographs.
All the best practices in this guidebook have been gathered from the builders that have participated in the Productivity Improvement Project (PIP) on Trade & Project Level Productivity Study. References have also been made to international standards, e.g. the ASTM E2691–Practice for Job Productivity Measurements. It is a useful guide for builders who wish to measure the trade productivity in their projects.

The following sections show the steps involved when installing table formwork. While the specifi c construction techniques employed may differ, these are the common stages of work that are commonly carried out on site.
Dismantling of table formwork include striking of infi ll forms, lowering down and shifting of formwork out of building.
