In 2017 Zeeland sought to commission a works contract to widen the N62 road ‘Tractaatweg’ (100 km/h) in Zeeuws-Vlaanderen from one to two lanes in each direction and to build four new viaducts. The N62 is a major road connecting the seaports and the industrial areas of Ghent (in Belgium) with Terneuzen and Vlissingen (in the Netherlands). The Province of Zeeland sought to widen this North-South road connection to help improve the flow of traffic and road safety.

During the dialogue process, the companies who responded to the tender were asked to deliver two specific biobased products plus one or more products from a pre-identified list of market-ready bio-based options. In addition, they were asked to deliver at least one ‘pilot testing’ of their own choice from a list of pre-identified innovative bio-based products.
Boskalis used four biobased products:
- biobased geotextiles for ground coverage
- biodegradable tree anchoring system
- biobased road hard shoulders
- development of biobased roundabout signs
“Our starting point was that biobased products are not a nice to have but a must have in this tender.
During the dialogue process, the companies who responded were asked to deliver two specific biobased products plus one or more products from a pre-identified list of market-ready bio-based options. In addition, they were asked to deliver at least one ‘pilot testing’ of their own choice from a list of pre-identified innovative bio-based products.
The rationale behind the approach used was to provide the companies taking part in the competitive dialogue process as much flexibility as possible, whilst ensuring that the expectations of the contracting authority would also be met.
