Danish Precast

Precast concrete construction is very common in Denmark. Usually the concrete slabs are cast in a climate controlled warehouse, allowed to cure, and then trucked to the site where they are immediately assembled with a crane. This method of construction works well here because bad weather has little impact on the process. When you build with cast-in-place concrete or even steel you have to be ever mindful of the forecast temperature and humidity. Unexpected freezing temperatures can destroy curing concrete.

Precast buildings, while certainly safe and stable, are basically a house of cards. Shaking the table is definitely a bad idea. Earthquakes never occur in København so this is not a concern, but I don't think we would want to build this same tall precast building in California.
