The fully pre-engineered BEBO system features the world’s largest precast concrete arch structure offering spans from 3.7m to, in excess of, 35m. Integrated on similar schemes to the Multiplate Steel Structures, the BEBO arch is a standardised precast concrete arch system that has a patented design. It is used widely for the design and construction of earth overfilled bridges, tunnels, culverts and other underground structures.
The BEBO arch consists of a series of predefined highly efficient and optimised arch shapes. The different standard spans and rises allow the designs to be adapted to accommodate different layouts such as shallow and high-grade separation applications. This allows for various clearance profiles for highway overpasses as well as the fulfilment of stringent flow capacity requirements for river crossings.
There is a noticeable increase in the requirement of Green Bridges to improve aesthetic appearance and create a link between biodiverse habitats. Using our BEBO precast arch, our Green Bridges create a connected and safe landscape that will maintain, restore and enhance historical and recreational features. The Green Bridge sits in a cutting allowing the surrounding landscape to wrap around the structure. The structure itself has little visual impact on the surrounding environment which is critical when new road and rail links are being developed.
The slender section thicknesses and the reduced requirement for structural reinforcement helps reduce the overall installation cost; this coupled with the limited maintenance requirements the BEBO Green Bridges are becoming the preferred choice on strategic infrastructure projects.
No approach slabs, transition joints and moving bearings reducing site infrastructure and installation time.
Pre-engineered arch design compliant to the latest Eurocode standards.
Variety of shapes, span and end treatments to suit a range of applications.
