SCAL will administer Green and Gracious Builder Scheme (GGBS) from 1 April 2021

With effect from 1 April 2021, The Singapore Contractors Association (SCAL) will officially take over the administration of the Green and Gracious Builder Scheme (GGBS) from the Building and Construction Authority (BCA) with the objective of playing a bigger role in raising the environmental consciousness and professionalism of builders.

Introduced by BCA in February 2009, the GGBS is a certification scheme that provides a benchmark of a builder’s corporate social responsibility to the environment and public during the construction of projects. It also sets standards for green and gracious practices that builders can implement to address environmental concerns and mitigate possible inconveniences to the public caused by construction works.

Firms in the construction industry should step forward for this certification to minimise noise, danger and inconvenience to our communities during construction; and promote the widespread adoption of sustainable construction in Singapore.


Both the GGBS and GGBS (SMC) certification schemes are highly recommended for all builders.

The GGBS certification was made a requirement under the Contractors Registration System for firms registered under work heads CW01/02 (Building work/Civil Engineering work) A and B grades since 2015 and 2016 respectively. Builders wishing to apply for or retain their BCA Contractors Registry System (CRS) registration in work heads CW01 and CW02 and financial grades from A1 to B2 are required to maintain their GGBS certification. 

Based on the score, GGBS firms will be rated in four tiers: Certified, Merit, Excellent and Star.
