Exploiting Geomatics Potential in Construction: the integrated BIM-GIS approach in the construction phase

Here are the benefits of the integrated BIM-GIS approach in the construction phase of a building or infrastructure

The integrated BIM-GIS approach is increasingly common in the construction sector, applied across all stages of a built asset’s lifecycle: planning and design, construction, maintenance, demolition. These methodologies converge in their philosophy, focusing on associating data with digital objects; thus, not only optimizing project management but also broadening the view of the spatial context, making projects more effective and connected to the terrain.

An integrated BIM-GIS approach, centered on data, generates a deeper understanding of the work and the urban and naturalistic context, enabling an informed decision-making process, greater stakeholder involvement, and faster, more efficient processes. This optimization spans every phase of a building’s lifecycle, with BIM providing detailed three-dimensional information on a structure’s physical aspects and GIS managing and analyzing geographic data.

BIM GIS Integration

The interaction between these technologies opens new perspectives for planning and executing construction projects, aided by GIS Digital Twins, digital replicas seamlessly combining geospatial data with information from BIM models, immediately usable in designing, constructing, and maintaining a structure. Synchronizing geographic data and design information provides a comprehensive, real-time view of construction operations. A synergistic approach enabling more efficient project and resource management, achieving previously unimaginable performance levels in the construction industry.

The advantages of the integrated BIM-GIS approach in the construction phase

The integration of Building Information Modeling (BIM) and Geographic Information Systems (GIS) proves crucial, offering significant benefits during the construction phase of projects of any complexity. Similar to the planning and design phase, during construction, the integrated BIM-GIS approach provides numerous practical advantages: for instance, it enables better site planning and management, optimizing resources and reducing waste. Through site analysis based on geospatial data, it assesses ground conditions, identifies potential risks, and efficiently plans construction activities. 3D visualization and geospatial data management enable detailed, real-time monitoring of work progress, facilitating communication and prompt problem resolution.

Contextual Visualization

As previously explored in the article “Planning and Designing with the Integrated BIM-GIS Approach,” the synergistic interaction of geographical data from GIS with BIM model information offers a broader, contextual perspective, enabling stakeholders to fully grasp the context in which the building structure will be placed. This integrated approach assesses the project’s environmental impact concerning surrounding elements, aiding in making informed decisions during design and construction. Additionally, the fusion of geographical data and BIM information identifies geospatial constraints, anticipating their identification to mitigate potential construction issues.

Resource Management

Another crucial aspect of BIM-GIS integration is optimized resource management during the construction phase. Spatial analysis provided by GIS can optimize resource allocation, such as:

  • Material Logistics – by assessing access routes and the best logistical strategies through spatial analysis, it optimizes the transport and storage of construction materials, reducing waste and costs.
  • Route Planning – leveraging geographical data allows planning optimal paths for machinery and vehicles during construction, reducing downtime and optimizing operational efficiency on-site.

Risk Reduction

Integrating detailed project data with geographical information helps mitigate construction-related risks:

  • Impact Analysis – BIM-GIS integration allows simulating construction impacts in advance, reducing the risk of unforeseen or negative impacts on the surrounding environment.
  • Information Management – sharing and centrally managing information between BIM and GIS reduce communication and interpretation errors, improving data consistency and reducing costs associated with corrections during construction.

Construction Site Progress Monitoring

During construction, tracking site progress is essential to ensure the project remains on schedule. BIM-GIS integration enables real-time interactive maps of the site, displaying the positions of different work teams, equipment, and materials. This allows dynamic planning and prompt resolution of emerging issues.

Quality Control

Quality control is crucial during construction. Using BIM and GIS data allows constant comparison between on-site construction and project plans, promptly identifying any discrepancies. This ensures the final result aligns with project specifications and requirements.
