Wanson has implemented an Integrated Management System (IMS) to prevent pollutions and work-related injuries while providing quality products and services. Our efforts to develop projects in a sustainable way have been well recognized: in 2023 Cheung Sha Wan Catholic School has been awarded with final BEAM Plus Gold ratings by the Hong Kong Green Building Council (HKGBC), and most importantly we have achieved triple certifications:

QMS ISO 9001:2015, EMS ISO 14001:2015, and OH&SMS ISO 45001:2018.
