Contract conditions

Contractvormen

Jan De Nul Group can be an all-in partner for clients.

We do more than contracting alone, we act as ‘unburdening’ partner: from responsibility for the design through quality monitoring of all suppliers and subcontractors up to all-in concession contracts or financing programmes. Jan De Nul Group can offer a comprehensive portfolio for every activity in whatever form.

EPCI-contracts

These projects go way beyond the traditional installation services. We are responsible for integrated project studies or specific strength calculations (engineering) and for the manufacturing of parts, either outsourced to suppliers or made internally (procurement & construction). In these projects, Jan De Nul Group also assumes full responsibility for the overall quality assurance.

    We designed and built the concrete foundations on a floating pontoon. We were also responsible for transporting and installation.

Concessions

The client remains owner but entrusts the whole project to us. Depending on the specific needs, we can take on the financing and actual realisation of the project as well as the operation and maintenance of the structure.

    We deepen the 95-km access channel to the port of Guayaquil in Ecuador. We are also responsible for the operation and maintenance of the channel under a 25-year concession contract. We finance the costs ourselves and recover them by charging toll.

Public Private Partnerships (PPP)

We have extensive experience in Public-Private Partnerships (PPP): a partnership between a public authority and private companies for the realisation of projects. Think of infrastructure works such as roads, bridges or tunnels but also the construction and operation of residential care centres, hospitals and industrial complexes.
