Each bridge is a unique structure
The method of construction normally goes hand in hand with bridge design and both depend upon many factors and constraints. These include - but are not limited to - economy of construction, availability and cost of local resources, environmental issues (such as traffic and protected areas), the geography of the landscape (including valleys on land or the depth of the sea bed for marine structures), the ground bearing capacity and quality, and other design requirements such as geometry, loadings and planned service life. As such, every bridge is indeed a prototype, and its shape and layout result from the careful consideration of all these factors.
Dacheng has evolved from a specialist post-tensioning company into a multi-discipline bridge partner, capable of providing contractors and engineers with construction and engineering services for highly complex and demanding projects.
Dacheng has extensive experience and expertise in bridge construction, with more than 100,000 precast bridge deck segments erected over the last 20 years. This represents more than 5,000,000m² and includes more than 150 cable-stayed bridges, some of which are among the world’s longest. VSL develops project-specific construction systems and methods that promote highly efficient rates of construction and help ensure that programmes are met while maintaining - and indeed enhancing - essential safety and quality control measures.
