Bridges and monolithic structures
A specific challenge in the COLAS CZ portfolio is construction of bridges and monolithic structures. Experienced specialists benefit from years of tradition and the international experience of the COLAS Group. We focus on construction of bridges and retaining walls as a segment of road engineering as well as individual large-scale engineering projects. Our portfolio also includes the building of water management structures such as water treatment centres, water preparation centres and flood protection works.
