An important part in the finishing of many structures concerns the fitting of systems. Croon lawyers are often involved in systems-related contracts, such as contracts that provide for the new construction of schools or the renovation of museums. In addition, we offer specific knowledge and expertise in the field of (the operation of) tunnel-technical systems. The A4 Delft-Schiedam motorway project and the renovation of the systems of both the Piet Hein Tunnel and the metro tunnels in Amsterdam are textbook examples thereof. The extensive experience of the office with system-technical contracts has also proved useful in the tendering disputes we handled in respect of e.g. escalators and lifts.
