Engineering at its finest
The complex relocation operation is part of the broader R4WO project, a major infrastructure initiative led by De Werkvennootschap in partnership with the BRAVO4 consortium. BRAVO4 consists of BESIX, Stadsbader, EPICo, I4B – The Belgian Infrastructure Fund and RID PPP (Rebel en Abrdn). BESIX is honoured to contribute its expertise to this landmark undertaking.
This is engineering at its finest, made possible by a multidisciplinary team committed to excellence. From precision cutting and lifting to controlled transport and reassembly, each phase of the operation was executed with care and coordination. - Gunther Muyshondt, Project Director at BRAVO4
The relocation unfolded in three phases. Initially, the bridge was dismantled into three large sections in preparation for transport. Two side sections, each weighing approximately 850 tonnes, were relocated using Self-Propelled Modular Transporters (SPMTs). The central section, weighing approximately 1,150 tonnes, was moved via pontoon. Once in place at the temporary location, 100 metres from the original site, the sections were reassembled, bridge joints poured, the surface repaved, and lane markings applied, making the bridge ready for traffic. This work method, with traffic remaining in service on the other half of the bridge, helped minimise traffic disruption and ensured safety during the operation.
While the execution was largely seamless, the operation was not without its challenges. “One of the sections didn’t respond as expected during lift-up,” explained Guillaume Cornille, Project Director at BESIX. “At 3 a.m., our teams reconvened to adapt the plan, working in true collaboration to keep the project on schedule.” The swift problem-solving was led by BESIX Engineering, whose technical acumen helped restore momentum and deliver the operation on time.
“The successful outcome is the result of months of preparation, engineering excellence, and close collaboration between all stakeholders,” said Muyshondt. “It’s a privilege to witness such a high level of dedication among partners, in both the field and the design office.”
With the temporary bridge now open to traffic, the next phase of the R4WO project begins: the demolition and complete reconstruction of the original Ringvaart Bridge, which will be rebuilt to meet modern design and capacity standards.
BESIX extends its thanks to all teams, partners, and consortium members who contributed to this complex and successful operation.
