The power of knowledge

is the difference in construction quality and cost.

Your partner

in Quality, Safety, and Innovation

Confidence you can build on
At Seconed, everything revolves around trust. For over 90 years, we have operated as an independent, ISO/IEC 17020:2012 Type A-accredited inspection body, specializing in technical inspections and quality assurance for construction projects. Whether it's residential, commercial, or infrastructure construction, we assess designs, perform inspections, and guide commissioning processes with an objective and proactive approach. This helps reduce (failure) costs and risks, ensures compliance, and safeguards structural safety at every stage of your project.

Added value through collaboration
As part of the SECO Group, we have access to an international network of technical experts — from structural stability and façade technology to fire safety and building services. This collaboration enables us to offer tailor-made solutions that meet not only the standards, but also your expectations. With Seconed, you ensure both continuity and quality in every project — making building a whole lot more reassuring!

Projects we are proud of

Binck City Park - The Hague

Project Binck City Park is one of the largest and most complex inner-city developments in recent years. In this project, no fewer than seven different clients collaborated, each with their own requirements, standards, and interests. VORM acted as the coordinating and leading client.

City Bridge – Nijmegen

The City Bridge in Nijmegen – officially called The Crossing – is one of the most iconic infrastructure projects in recent years. This bridge not only connects the northern and southern parts of the city, but also serves as a symbol of renewal and remembrance. Various stakeholders, each with different requirements and visions, worked closely together on this remarkable project.

Afsluitdijk

The Afsluitdijk separates the IJsselmeer from the Wadden Sea and stands as an icon of Dutch hydraulic engineering. Completed in 1932, its primary functions are to ensure water safety from the Wadden Sea and manage water discharge from the IJsselmeer. Additionally, the Afsluitdijk serves as a crucial transport route, facilitating road traffic between the provinces of North Holland and Friesland, as well as enabling navigation between the Wadden Sea and the IJsselmeer.

Wind Farm – Reusel

The onshore wind farm in Reusel, consisting of five wind turbines, is a great example of sustainable area development. For this project, H4A was responsible for the design, construction, and technical assessment of the reinforced concrete foundations. This specialized process placed a strong emphasis on reliability and precision.
