Geospatial industry continues to evolve through a process of collaboration for almost every industry sectors all over the world, and as expected, the AEC industry is no exception to this. Though BIM continues to be a significant technology driver across all the major phases of the lifecycle of any particular construction project, geospatial information and technology continues to be embedded in the AEC industry. An integrated approach has come to the fore wherein different geospatial technologies along with BIM, i.e. GEOBIM solutions for construction, are used in a handful of projects all over the world. GEOBIM has proven to provide greater and improved efficiency, productivity and accuracy to construction projects. It has also smoothened the integration of work processes, accurate visualization and easy collective decision making.
This much needed integration of geospatial technologies with BIM, i.e. GEOBIM solutions has proved to be an effective tool to overcome numerous challenges that every construction project faces. Be it natural or man-made. This problem-solving is not only restricted to plan and design phases of construction project lifecycle but also in the later phases including project management and the final completion of project. This particular characteristic of GEOBIM integration is dictating the software construction market. Further they are indulging in partnerships and mergers and acquisitions among themselves as well as geospatial technology providers. In return it is improving interoperability in between two different technologies and opens up newer horizons for the AEC industry.
The lifecycle of any AEC project can be classified into five distinct phases. Integration of geospatial technologies with BIM are utilized in order to increase accuracy, efficiency and productivity across the lifecycle. Let us look at the use of these technologies along all phases of construction projects and their capabilities.
Survey and Plan: Technologies like GIS, GNSS, Remote Sensing having surveying and measurement capabilities are commonly used during this phase. 3D scanning tools like LiDAR, GPR, total stations, etc. and aerial photography tools such as UAVs and drones also finds its use in this phase. All these technologies play an active role in achieving different mapping capabilities like terrain mapping, land use mapping, site-suitability mapping, analyzing the climatic variability and the natural resource stocking of a site prior to site planning and designing.
Design: GIS technology is extensively used for visualization and analysis of site for design. Its integration with BIM and CAD is used in the preparation of 3D models and drawings in this phase.
