Three twin span ABM structures on the Prague Ring Road phase 513. CM4 combination of 52m2 wall and 225m2 roof. Span 2 x 16m. Each structure is 26.2m long and was installed in just 5 days. Structures initially designed as heavy in-situ but after value engineering changed to subtle precast buried system using in its favour the soil-structure interaction. Conclusion: lower price yet better quality of concrete elements from our precast plant and quick installation on site not limiting the main contractor in his ancillary works.
