New trend: “Volumetric Modular Construction” Volumetric modular construction is a process of off-site manufacturing of volumetric modules in a controlled environment at the industrialized facility (factory conditions) and assembly of these modules in order to create the main structure. Are Volumetric Construction and Modular Construction different from each other? 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 more..
