In the first part of the is\narticle, we discussed about the advantages of integrating GIS and BIM in a\nconstruction project. In this article, we will explore the current way of\nworking and its drawback. We will also discuss the future of BIM and GIS\nintegration and its impact on construction projects.<\/p>
Geographic context of a project is a vital factor in the decision-making process of a construction project. Over a period of years, GIS has evolved greatly and provides a first-hand context of the spatial conditions. GIS enhances the value of digital BIM Services<\/a> as it provides visual context. Integrating 4D BIM with GIS enables the project stakeholders to take informed decisions by foreseeing the impacts of the decisions before, during and after the construction of the project.<\/p> Current Approach: Fragmented and Disconnected Approach<\/strong><\/p> The current\nmethodology of working is such that the processes are prone to inefficiencies\nand more importantly, loss of critical data that leads to increased risks.\nThese factors are the key drivers that demand an integrated approach.<\/p> There are 3 major areas in the\ncurrent approach which call for an improvised methodology:<\/p> 1. Process of Project Handover<\/strong><\/p> The raw BIM data is handed over to the GIS\nteam. This is then updated manually in order to import it to the GIS database.\nAny mis-match is not reported back to the BIM team as this is a one-way channel\nof information flow; which is a drawback of the current process.<\/p> 2. Inaccessible Data<\/strong><\/p> Manually editing the data renders it\ninaccessible directly by the BIM software which makes the data outdated.\nMoreover, the chances of human error in the data input process can result in\nthe loss of vital information.<\/p> 3. Non-authoritative Systems of Records<\/strong><\/p> Data\nfetched from a non-authoritative system of records and incorporated in the GIS\ndata during manual addition can result in faulty and outdated design. The\nproject teams need to be more vigilant while utilizing the data.<\/p> New\nApproach: Integrated and Driving Smarter Decisions<\/strong><\/p> Architects,\nengineers, designers and GIS professionals need to adopt a different approach\nto deliver more and better with less efforts. Integrating GIS and BIM allows to\ncreate workflows where the data flows seamlessly from one system to another.\nEfforts are currently on to develop such a system.<\/p> By using\n“Data” at the center approach broadens and enhances the understanding of\ninfrastructure in the larger context of built and natural environments –\nenabling earlier and better-informed decision-making process, improved\nstakeholder engagement, and accelerated approval processes. This new approach\nultimately leads to a better decision-making ability.<\/p>
