About Nexum Construction
About us

A strong foundation.
A clear promise.

“Nexum” comes from Latin and means connection and commitment — values that define how we work as a full-service contractor in concrete works and groundworks. Connection means bringing together trades, people and delivery. Commitment means keeping our promises and taking responsibility for quality, progress and collaboration from start to finish.

We take on greater responsibility in the projects we commit to, while staying close to our people, our craft and the quality of our work. Our goal is an organisation built for growth, with a strong track record and lasting relationships.

Our story

From Ringstad Anlegg to Nexum Construction

Ringstad Anlegg AS was established in 2019 with one clear ambition: to deliver high-quality construction work with precision. Concrete works were the starting point.

Since then the company has grown from a small specialist team into an organisation of more than 50 employees, with revenue passing NOK 54 million and recognition as a DN Gazelle company — Dagens Næringsliv’s award for Norway’s fastest-growing firms — in both 2024 and 2025. Today we are building on our concrete expertise with a broader push into groundworks, excavation, roadworks, water and wastewater. That growth gives us the capacity to carry more responsibility in the projects we take on.

Nexum Construction represents the next chapter — a new name that carries everything we have built and looks ahead.

Our values

What we stand for, every day

We are building a culture where people care for one another, take responsibility for the whole and improve a little every day. At Nexum, there are clear expectations, professional pride and room for learning and development.

Nexum Construction — our values in practice

Pride in the trade

We are proud of the work we deliver — and here it is fine to make mistakes, as long as we learn from them.

Disciplined delivery

Clear routines, clear communication and predictability at every stage of the project.

Quality at every stage

From planning to completion — quality is not a step in the process, it is the process.

Close collaboration

We work closely with clients, project managers and partners — with clear communication and practical solutions.

Everyone improves a little every day

A shared team spirit and shared goals. We make room for everyone to develop — a little every day.

Safety comes first

HSE is not just a requirement — it is a value that shapes our culture and our routines.
