We deliver concrete works and groundworks for commercial and infrastructure projects in Oslo and Eastern Norway. We keep our promises and take responsibility for quality, progress and collaboration throughout the project.
Nexum Construction builds on the experience of Ringstad Anlegg. “Nexum” means connection and commitment — between ground and structure, client and contractor, and plan and completed project. We believe good projects are created through clear communication, practical solutions and delivery you can rely on.
We take on works contracts for both private and commercial projects — from concrete works to groundworks, excavation, roads, water and wastewater. Our approach is always the same: clear planning, skilled people and close coordination between contractors, suppliers and clients.
We work systematically with health, safety and the environment, with a dedicated HSE/QA manager, established routines and close follow-up on every site.
We deliver specialist work from ground to completed structure, with clear communication, predictable progress and solutions that work in practice.
In-situ concrete structures with control of progress, quality and documentation throughout delivery.
Site preparation, foundations and earthmoving — with sound logistics and orderly progress.
Precise coordination of water, wastewater and technical infrastructure, built for reliable operation over time.
Access roads, sub-base layers and tie-ins to existing infrastructure for robust, functional external works.
We are looking for skilled workers in concrete and groundworks — and a Project Manager.
We are happy to contribute early with practical assessments of feasibility, sequencing, logistics and interfaces. This enables better decisions before work starts.
We emphasise clear roles, expectations and accountability before mobilisation. It reduces misunderstandings and provides better control of progress and delivery.
On site, good operations are about planning, order and close coordination. We follow up continuously so deviations are caught early and the project stays on course.
Quality must be verifiable. We work systematically with HSE, QA and documentation throughout delivery.
