DWSS Hong Kong: The Construction 2.0 Compliance Playbook for 2026
The Digital Works Supervision System (DWSS) is now mandatory for many Hong Kong public works projects. Here is the modules, the deadline and the playbook for going live in 90 days.
Hong Kong's Development Bureau has made the Digital Works Supervision System (DWSS) effectively mandatory for public works projects through Technical Circular No. 3/2020 and the Construction 2.0 agenda. This is the practical playbook for going live — fast.
The five mandatory modules
- RISC form management — digital inspection requests with photo records
- Site diary — daily progress, labour, plant, weather
- Safety & environmental records — inspections, near-misses, permits
- Cleanliness records — daily/weekly photo proof
- Labour records — attendance, hours, wage compliance
Deadlines and cost caps
- DWSS must be operational within 3 months of project commencement
- Implementation cost cap: HK$10M or 0.5% of contract value, whichever is lower
- ISO/IEC 27001 alignment is the de facto security expectation
90-day deployment playbook
Weeks 1–2: scope modules, deploy mobile apps to foremen, onboard RISC workflows. Weeks 3–6: stand up cloud, identity and audit. Weeks 7–10: roll out site diary, safety and cleanliness modules. Weeks 11–13: training, hyper-care, government reporting.
