DEVELOPMENT OF A STANDARDIZED INTEGRATED BIM APPROACH FOR A VILLA PROJECT

Abstract

The process of managing a construction project is difficult and time-consuming. Since the jobs associated with a project are diverse and complex, involving numerous stakeholders in various phases, successful project management is not easy. Moreover, reliance on manual labour and the reluctance to adopt automation in planning and design, make management of projects difficult. However, there is ample scope of information technology in construction industry and within the context of sustainable development, the expectations associated with efficient project management has increased multi-fold. Building Information Modelling (BIM) offers great support in project management, together with advanced technologies as knowledge systems.BIM is a progressive intelligent 3D model-based process that gives Architecture, Engineering and Construction (AEC) professionals the insight to plan, design and manage more efficiently. In an attempt to simplify the efforts of the industry and to tap the potential of the technology, this study proposes an integrated BIM approach for a double-storeyed villa so as to develop a complete integrated 4D/5D BIM workflow. The dominant aim of this study is to standardize the BIM metadata with the help of a BEP (BIM Execution Plan), which is limited to 5D.The management tool used in this work is Bexel Manager. This work also proposes the standardization of a workflow template in order to replicate similar projects in future, leading to less rework and more of optimization and customization of digital workflows. With the intention of keeping the project as close to the industry and using authentic data, the labour productivity was determined through a questionnaire survey. The output quantity per work hour was examined from 30 responses from the industry. To calculate the productivity criteria and schedule the project, this output quantity was employed as an input. Autodesk Revit was used to create the villa's 3D model. Primavera P6 was used to construct the 4D/5D model after analysing the quantity take-off and Bill of Quantities (BOQ). A clash-free model was created once the 3D model's clashes were identified. As a result, the cost disparity was discovered and a template of the same was standardized. After that, the properties required to create a flawless BIM model were standardised in accordance with LOD 300 in the BIMForum's ISO 19650 series, in the form of a template. The constructed villa model underwent a property check, and a report was simulatively generated. Then a template defining the quantity take-off structure was created for the typical villa project and was standardized. iii Comparably, all the activities required for a villa project was sorted and standardized. Also, as a part of deriving the creation template, the methodology of the project was generated in two levels of cost item. As a result, the entire workflow of a double-storeyed villa has been standardized and the schedule has been generated effortlessly. This template can be used to develop the workflow/schedule of any residential building smoothly. Ultimately, the standardized workflow has been suggested to experts in construction industry, which comprised of project managers, engineers and supervisors, and the feedback was recorded and simulated. The upshot showed that the integrated BIM approach was significantly and considerably excelling the traditional mode of project management
