COMPARISON OF GENERAL TECHNICAL PARAMETERS, WORKABILITY AND FIRE PROTECTION OF ROLLED PROFILES VS. RHS STEEL FRAMES OF 3D-VOLUMETRIC MODULES

Prefabricated volumetric modules with steel frame have recently become a segmentation trend for real estate, commercial multi-storey housing and office buildings projects. The obvious benefits of reducing construction time, number of site activities and related overheads as well as better quality control system compare to on-site production, 3D volumetric construction still associated with significant risks related to relatively high construction cost, potential logistics issues and lack of proven point of reference and frameworks (so-called “best practices”).
