Replacement and renovation programme for Bridges and viaducts

On 20 February 2024, Rijkswaterstaat announced that the framework agreements for bridge and viaduct recalculations were concluded. Witteveen+Bos is entrusted to work on this major replacement and renovation programme (VenR) as one of the preferred suppliers.

Many bridges in the Netherlands were built in the third quarter of the last century. Their use has intensified over the years, thus increasing the load. In order to keep the national infrastructure up to standard, it is necessary to assess the (remaining) lifespan of infrastructure engineering structures and, where necessary, proceed with renovation or replacement.

Over the next few years, some 50 fixed steel bridges, 30 to 50 movable bridges and 245 concrete bridges and viaducts under RWS’s management must be recalculated. Due to the specialist character and size of the replacement and renovation programme, RWS has opted for a framework agreement. This eliminates the need for repeated competitive tendering, which reduces tender effort and enables uninterrupted collaboration and acceleration. The term of the framework agreement is 6 years, with a 2-year extension. ‘We worked on the tender with a large team, and we are very pleased with the result. By being awarded the framework agreements for concrete and steel bridges, Witteveen+Bos has secured a substantial amount of work for at least six to eight years. For the contract for concrete bridges, we even obtained the highest score,’ said Hans van Daelen, leader of the Replacement and Renovation of Civil Structures PMC.

‘For the contract for steel bridges, we will start with the Moerdijk Bridge, a steel tubular structure from the late 1970s. And for the concrete part, we will start on a tubular bridge in March. Recalculation is pretty specialised work. Unlike calculations for new construction, recalculations are different every time and require a lot of figuring out. It is also known as ‘forensic engineering’. It comes in handy that we have already gained the necessary recalculation experience with both steel and concrete civil engineering structures in recent years.’
