What is 4S?

4S (Safety Smart Site System) is a government-recognised product framework under the Construction Innovation and Technology Fund (CITF). Bottom line: if your project is compliant and you choose pre-approved 4S products, the government pays — up to 50% of costs, no repayment required.

How Much Does the Government Pay?

💰

Total funding cap per applicant raised to HK$7.5M (incl. innovative building tech & BIM)

🎯

Of which HK$1.5M is dedicated to 4S systems — for purchases/leases after 1 April 2023

📊

Locally developed tech: government covers up to 50%; other products: up to 30% — that's half off

📈

From 20 May 2024, the scope expanded to cover network costs, extra manpower, maintenance, and technical support as well
