Frequently asked questions
Do I need BCA registration or licensing?
Builders, specialist contractors, and construction-related firms must register with the Building and Construction Authority (BCA) under the BCA Contractors Registry System or relevant licensing scheme.
What workplace safety requirements apply?
The Workplace Safety and Health (WSH) Act requires risk assessments, safety management systems, and specific permits for high-risk construction work. MOM enforces compliance.
Are there minimum financial requirements?
BCA registration grades (A1 to C3) have minimum paid-up capital and net worth requirements. Higher-value projects require a higher registration grade.
What environmental impact obligations apply?
Construction sites must comply with NEA regulations on noise, dust, and waste management. Environmental impact assessments may be required for large-scale projects.
What is SSIC and why does it matter?
The Singapore Standard Industrial Classification (SSIC) is the national system for categorising business activities. It is mandatory at ACRA registration and is used by IRAS, MOM, and other government agencies for tax, licensing, statistical, and policy purposes.
Do I need to register with this SSIC code?
Every business entity registered with ACRA must select at least one SSIC code that best describes its principal economic activity. You can declare up to two codes — one primary and one secondary — via BizFile+.
