ID card requirement Denmark is becoming an important topic for large construction and civil engineering projects.
Denmark has passed a new law introducing ID card requirements on large construction and civil engineering projects.
The law was passed by the Danish Parliament on 3 September 2026 and is expected to apply to construction and civil engineering projects with a value above DKK 100 million. The requirement includes ID cards, registration of time spent on site and reporting obligations to the Danish Working Environment Authority.
However, the practical model has not yet been finalised. The Danish authorities still need to decide whether the ID card system will be handled as an industry-driven solution or as a state-issued ID card administered by the Danish Working Environment Authority.
The current expectation is 2028 if an industry-driven solution is chosen, and 2030 if a state-issued model is introduced.
For companies, agencies and individuals working internationally, this is an important development to follow. It shows a broader move towards stronger documentation, traceability and control on Danish construction sites.
What the ID card requirement means in Denmark
The new requirement will make worker identification and site presence more visible on large projects.
Workers on covered construction sites are expected to be linked to an ID card system, and time spent on site must be registered. For international workforce setups, this increases the importance of having employment details, worker documentation and project information ready before site access is needed.
The requirement does not replace employment, payroll, tax, immigration or posted worker obligations. Instead, it adds another practical layer to project readiness.
Why it matters
Large construction and infrastructure projects often involve several contractors, subcontractors and international workers on the same site.
When ID card requirements become part of the site process, access may depend on more than worker availability. It may also depend on whether the worker can be identified, registered and connected to the correct employment setup.
For agencies and businesses supplying workforce into Danish projects, this makes early coordination more important.
What to watch next
The law has been passed, but the practical setup is still being developed.
Companies should follow whether the final solution becomes industry-driven or state-issued, because this affects both responsibilities and timing.
Northern Partners will continue to follow the development and share relevant updates as the practical model and implementation timeline become clearer.
The practical takeaway
Denmark’s new ID card requirement makes site-level documentation more important on large construction and civil engineering projects.
The exact setup is still not final, but the direction is clear: large projects will require stronger control of who is on site, how workers are identified and how time on site is registered.
For agencies, businesses and individuals working internationally, ID card compliance should be treated as an upcoming site access and documentation requirement.
