Constructability assessment of cast in-situ, precast and modular reinforced concrete structures

This research lays out the foundation of constructability analysis of Cast in-situ, Precast and Modular RCC Structures using Building Information Modeling (BIM). This research documents three different construction techniques, which are vital components in this modern construction industry. The theory is to predict the usability of the features during the modeling of a structure. The sample model is used to integrate these techniques, and each factor is given a parametric value based on quality, time, safety, and cost involved in casting them. These four factors are evaluated from the values obtained from the BIM model. On getting the required values, they are matched with the ones obtained from the current industrial components. Once the value of the parameters matches up to an acceptable limit of 10%, it is considered a validated value of the parameter. Once the validation of parametric values is done, a standardized mathematical model is developed using Linear Programming (LP). This model helps the user to obtain different parametric values by merely feeding the required input data like dimensions and materials, and so on. To reinforce the concept, the effect of the overall performance of the structure using constructability factors is assessed. The modular RCC structure is corroborated to be the most comprehensive and advantageous system. (c) 2020 Elsevier Ltd. All rights reserved.
