Volumetric structures are a type of modular construction. Fundamentally, volumetric structures are modular structures in respect of manufacturing process; but nevertheless, all modular structures are not considered volumetric. Modular construction is the assembly of one or more components manufactured off-site. They have a wide variety of uses in numerous sectors with the philosophy of Plug & Play such as residential complexes, hospitals, schools, shopping malls, labor camps, defense industry and many more.
