Sustainable modern construction practices using modular-based construction technology have superiority in terms of productivity and sustainability. With the Design for Manufacturing and Assembly (DfMA) concept, most of the work will be done off-site, allowing for more guaranteed and controlled quality of construction elements, reduction in labor and duration of work, and reduction of waste and environmental disruption cause by construction procurement. Despite these advantages, the main challenge in relying on this construction method is the addition of connection points and the limitations of studies that can map the potential advantages of applying it. For this reason, further studies are needed to shed light on the use of steel modular system for the national construction industries that will be studied form both the structural and construction engineering management aspects. From the structural aspect, the response of a typical steel modular structure subjected to the probable strong earthquacke will be observed using Response Spectrum Analysis (RSA) and Linear Time History Analysis (LTHA). By assuming that the connection between the modules (intra-modules) is semi-rigid, the system will be optimized according to the structural performance parameters, namely; strength (stress-capacity ratio of the structural elements), stiffness (inter-story drift) and structure’s expected failure pattern based on the design requirement provided by SNI 1726:2019. The result of the structural aspect is a typical steel module design, along with its constituent elements and intra-module connections in accordance with the design requirements based on SNI 1729:2020, SNI 7860:2020 and SNI 7972:2020. From construction engineering management aspect, the discussion focuses on reducing the volume of work, trade-offs and comparisons between construction methods of conventional and modular system, and efforts to improve environmental quality. The sustainability aspect which is a significant factor in the use of a typical steel modular system will be reviewed in terms of cost, quality and project execution time
