Conventionally, brick and mortar data centers are built using cast in-situ concrete construction. The floor loads are substantially higher than IT/office buildings. This construction method is widely used for DC businesses across the globe as it is proven and evolved over the years.
Some data centers are constructed using a combination of cast in-situ concrete and precast elements, for flexibility, speed of construction and site space management.
Another construction technology used for data center is the use of pre-engineered and prefabricated structural steel (composite steel construction). It offers enhanced speed of construction albeit at an additional cost.
