Rijkswaterstaat wants a smooth and safe flow of waterway traffic with modern lock complexes in addition to optimum protection of the Netherlands against water. It is outsourcing the maintenance of the locks and bridges in the Lake IJssel area for a period of five years.
With a multi-disciplinary and result-oriented contract, the “Sherpa” collaboration between Arcadis and Croon Elektrotechniek is responsible for the maintenance and upgrading of bridges and locks around the causeway (Afsluitdijk), Enkhuizen, Lelystad and the bordering lakes (Randmeren). The maintenance is set up and carried out on a risk-controlled basis. This new approach has been developed together with Rijkswaterstaat. It includes the maintenance of the electrical and mechanical installations and resolving civil engineering damage. Also included are the renovation of the lock complexes at the causeway such as the modernisation of the control and operation, the overhaul of the swing bridges, locks and sluices and the renewal of the buffers and channelling.
Sherpa combines analytical skills with implementation expertise. The added value lies in the vision and approach. Sherpa looks beyond the five-year period because the locks and bridges could last 50 or even 100 years. Sherpa proposes Reliability-Centred Maintenance - a maintenance concept that covers a longer period of time. The basis for this is connecting the broad knowledge in various fields with the ambitions of the client. For this, Croon is the expert in the field of electrical solutions for tunnels, bridges and locks and Arcadis in the field of asset management and water management.
