A lot of resources are invested in road development. More than often, multilateral development banks finance (rural) road improvement projects to accelerate urban development. While new roads are vital in developing countries, urbanized cities are dealing with an increasing amount of congestion, forcing them to expand capacity.
For both cases SBE has the proper experience and know-how to prepare a mobility plan, master plan and the technical design of the roads, interchanges, exits,... Via our trusted partners, we can also provide environmental and social impact assessments and all other aspects which are related to these works.
Tunnels are common in populated areas where they add capacity and only leave a small ecological footprint. Not only in congested city centres, also in mountaineous areas and to cross rivers, tunnels are a viable option, although tunnels are -in most cases- considerably more expensive than bridges.
SBE has experience in tunnel design while facing challenging boundary conditions. We can take care off the civil engineering design as well as the electromechanical engineering design (ventilation, lighting, fire safety,...). Combined with our road development team, we can offer all required skills and resources for any tunneling project.
Bridges are not only structures which cross a river or road, they are also landmarks where archituectural design often takes priority over functionality. Therefore the design of complex bridges can face the engineer with difficult challenges. Bridges can be vital for the accessibility of remote villages in developing countries. In such cases, design aspects are optional. Easy-to-build sustainable bridges with locally sourced materials at low cost are preferred.
SBE has made detailed engineering designs of bridges across the world made of steel, concrete and mixed steel/concrete. The following types of bridges have already been studied (static & dynamic analysis):
- Truss bridges
- Bowstring bridges
- Cable stayed bridges
- Movable bridges
- (Continueos) plate girder bridges
- Rolling bridges
- Pedestrian bridges
Spans vary from small to several hundreds of meters.
