Retractable Roofs
Sporting activities now draw very large crowds willing to pay high prices for events. This has made greater sophistication in sporting venues economic. As sport goes on throughout the year and climate cannot be controlled the solution is often to enclose the stadium for part of its time in use. The first application was in the USA in 1961 and gradually they have become more widespread.
They are normally prestige projects and often employ the world best architects and structural engineers. Thus, there do not tend to be any common designs. Gantrail have now worked with a number of project teams to install such roofs in a number of parts of the world.
Sometimes there is a requirement for more than one function in a sports venue and this can entail reconfiguration of the pitch. This has entailed banks of seats on rail mounted systems and elements of the sporting ground surface needing to be slid into and out of place.
