      Frequently Asked Questions
Q1. What is the aim of the ePSS?
A1. Project productivity is defined as the amount of square meter of floor area completed per manday. In order to calculate the project productivity, BCA collects productivity data of building projects on a monthly basis using the ePSS. The builders will monitor the manpower usage in their projects and submit the manpower usage data to BCA through the ePSS. From the data collected, the industry average project productivity for different building categories will be calculated.
Q2. How is the industry average project productivity beneficial to the builder?
A2. The industry average project productivity can be used to assess a project’s productivity performance and the builder can set improvement targets for future projects. In addition, the manpower data is one of the submission requirements when a builder applies for the BCA’s Construction Excellence Awards and Construction Productivity Awards.
Q3. What are the projects surveyed under the ePSS?
A3. The projects will include new building projects, upgrading and A&A projects with GFA more than 5000m².
Q4. What is the definition of project productivity?
A4. The project productivity is defined as the amount of square meter of floor area completed per manday.
The project productivity is calculated as follows:
Project Productivity =          Total constructed floor area (m2)
  Total number of site workers (mandays)
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.
Q5. What is the definition of total floor area?
A5. Total floor area will include the Gross Floor Area (GFA), roof area, environmental deck and basement carpark area, if any.
Q6. What is the definition of one manday?
A6. One manday is taken as one worker working for 8 hours. Thus, if the worker works for 12 hours on a particular day, the actual manday clocked by worker shall be calculated as 12/8 = 1.5 manday
Q7. For a worker doing multiple trades, which trade do I include the manpower under?
A7. A multi-skilled worker who spends more than 50% of his time on a particular trade in one day shall be recorded under that trade even if he performs other trades on the same day.
Q8. Is the submission of the manpower data compulsory?
A8. In conjunction with the enhanced buildability framework [Regulation 10 of Building Control (Buildability) Regulations 2011], it is a mandatory requirement for builders to submit construction productivity data to BCA from 15 July 2011. This is applicable to projects with GFA more than 5000m².
Q9. Can a builder have more than 1 user account in the ePSS?
A9. Yes. Each builder should assign an ePSS administrator from his/her company. BCA will issue a Username and Password to the ePSS administrator. The administrator can log into the ePSS and then issue multiple accounts to other users in the company, e.g. one account for each project site. More details can be found in the User Guide.
Biometric Authentication System (BAS)

Q1. What are the hardware requirements for BAS?
A1. The hardware requirements shall include the following:

a) Biometric readers that has the following features:

• Located at all worksite entrance and exit for the purpose of electronically monitoring and tracking the manpower usage throughout the contract duration.

• Robust and durable design that is suitable for rugged construction environment.

• Fast and secure sensor that accurately captures and authenticates distinguishing physiological traits. At each controlled access location, the system shall be able to achieve a maximum clearance time of 1 minute for every 10 persons.

b) Provision to guide the flow of workers (e.g. turnstiles and railings)

c) A real time monitoring and recording device installed at each controlled access point to prevent any fraudulent attempt by the site personnel.

d) Suitable measure(s) (e.g. backup battery supply etc.) such that the integrity of the manpower monitoring data is not affected during power outage.

Q2. What are the software requirements for BAS?
A2. The software requirements shall include the following:

a) Accurately monitor and track the manpower under their respective trade.

b) Generate raw data or output in the required format which shall include employee name, date, clock in time, clock out time, tabulation on the number of hours at site.

c) Generate the manpower report according to BCA’s current ePSS in Microsoft Excel format (please refer to Appendix A for building project template and Appendix B for rail project template). The Contractor shall refer to BCA’s website ( https://www.bca.gov.sg/epss/ ) for the latest requirements on manpower submission to ePSS.

Q3. What is the cost of setting up the BAS together with all the hardware and software including operation and maintenance cost?
A3. Generally, the cost of setting up a BAS system on the site that included the software, hardware, turnstile and railings for 2 access points is about $30k to $40k. Nevertheless, the price of BAS system varies according to site condition and system requirement. The user should consult the biometric system suppliers and select a system which suits the project site.

For BAS that will be adopted in construction projects to monitor the manpower usage and linked to the submission of manpower data through the ePSS, builders can seek for financial support to defray the cost of adoption from the Mechanisation Credit (MechC) Scheme under the Construction Productivity and Capability Fund (CPCF).

For more information on the MechC scheme, please refer to http://www.bca.gov.sg/MechC/mechc.html.
Q4. Is the installation and operation of the BAS compulsory?
A4. To enhance the reliability and efficiency in the collection of Construction Productivity Data, builders need to install and operate the BAS for building works with Gross Floor Area (GFA) of 5000 m2 or more submitted for Planning Permission on or after 1 November 2014. This is mandated under Regulation 10(a) of the Building Control (Buildability and Productivity) Regulations 2014. Builders will submit the Construction Productivity Data obtained from the BAS via the ePSS.
