When Is a Design for Safety Professional Required?
This page gives a general, qualified overview only. It is not a substitute for checking the current regulatory position for a specific project.
Design for Safety obligations in Singapore are commonly associated with construction projects above a contract-value threshold, and with projects that modify a structure that already has a DfS Register. Whether a specific project is covered, and what exactly is required, depends on the current regulations and the project's own facts — always verify before relying on any general statement, including this one.
General factors that commonly matter
Contract value
Singapore's Design for Safety framework has been associated with a contract-sum threshold for construction work. Confirm the current threshold and how it is calculated for the specific project.
Existing DfS Register
Works that modify a structure which already has a DfS Register may fall within scope regardless of the new work's contract value.
Project type
The nature of the works (new build, addition and alteration, temporary structure, and so on) can affect which requirements apply.
Appointment structure
Who is engaging whom, and at what point in the project, can affect how DfS obligations are best discharged.
This page does not state a specific statutory threshold as current, ongoing law for every project. Contract-value thresholds, exemptions and scope under Singapore's WSH (Design for Safety) framework can be updated. Verify the current regulations and, where in doubt, obtain project-specific advice before concluding whether a DfSP appointment is required.

If you are unsure whether a project is within scope, the safer approach is to engage a DfSP for an initial assessment early, rather than assume the project falls outside the requirements.
