Strategies to develop effective BIM models to suit 4d modelling

Abstract

Rapid upsurge of technology accredited 4D Building Information Modelling (BIM) as a BIM centric scientifically-derived scheduling process. It upgrades the project outcome, by reducing the substantial uncertainty exists with quality, cost and time. However, 3D BIM models are being advanced not only for 4D models but also for many other visualizing and informative purposes. Hence, necessity ascends to verify whether generally developed BIM models satiate required features of 4D modelling. Consequently, research aims to identify and verify extent of suitability and practicability of using BIM models in 4D modelling. The aim accomplished through a qualitative approach utilized with a desk study, unstructured interviews and a content analysis. It documented strategies and recommendations on how BIM models could be technologically advanced to ensemble 4D visualization. It was revealed that, prevailing BIM models are not readily acceptable for 4D modelling, which need to be refined marginally for real-world approach. Structural work packages, plant, equipment and accessories of building works can be directly used to 4D modelling as already developed whereas, integrated elements and finishing need few adaptations. Despite of few limitations, it is recommended more than 90% of elements developed in BIM models can be used for 4D modelling with certain modifications.
