About us

We are very proud to be organising the 27th edition of Infra Relatiedagen this year, the leading knowledge and networking event for the civil engineering sector in the north-east of the Netherlands.

Clients, contractors, suppliers and other professionals from the infrastructure sector come together to share knowledge, discover new developments and build valuable relationships. On the exhibition floor, exhibitors present their latest products, services, equipment and innovations for the infrastructure of today and tomorrow.

Infra Relatiedagen 2027 will take place on 16, 17 & 18 February 2027 at Evenementenhal Hardenberg.

That is why Infra Relatiedagen

Infra Relatiedagen is the place where the civil engineering sector comes together. Over the course of three days, you’ll meet around 15,000 professionals from the sector and gain direct access to clients, contractors, public authorities, consultants, engineers and other potential customers and partners.
