With constant increase in population in urban cities and the need for an efficient and urban infrastructure, especially in developing countries, linear infrastructure projects on roads, railways and utilities have gained popularity. Combined with ever-evolving technological advancements, this trend has gained momentum.

Construction companies across the world are working extensively on these projects. One such company which has earned great recognition in the field, especially in India, is L&T Construction. Over the past seven decades, the company has been transforming cityscapes with structures of immense size and grandeur. Its capabilities span the entire breadth of construction.

Amongst the company’s most recent projects are a series of elevated bridges in the city of Hyderabad, India. In order to monitor the development across these linear infrastructure projects, the organization chose Hexagon Geospatial’s products GeoMedia Professional and GeoMedia WebMap. These projects provided quick and full-featured maps for complex spatial analysis that helps in effective decision making. The solutions geographically tag location-based status, giving clarity and transparency on the work-in-progress at the construction sites.

Why use location-based systems?

L&T Construction uses 4D Building Information Model (4D BIM) dashboards that enable architects, designers, contractors and clients to visualize the entire sequence of events. Using these dashboards, crews at the building site update their log charts with status of the construction and various other field activities. This gives stakeholders a view into the progress of construction activities throughout the lifetime of the project. The BIM-centric approach helps to improve project management for construction projects of any size or complexity. But what could boost its efficiency and productivity further was integration of GIS.

The company needed a way to combine their BIM and GIS to monitor the project progress for linear infrastructure projects as this would lead to reduced cost of lifecycle management through effective asset definition. It would also avoid multiple uncontrolled copies of construction documentation and provide access to the right information at the right time. Hence, by this way it would empower resources to deal effectively with onsite problems.

Traditional BIM systems focussed on developing objects with the maximum level of detail in geometry, whereas, GIS systems could provide locations for the assets and information about the topography and relations between the objects in the GIS. This would open the possibility for sophisticated analysis on assets in the 4D BIM. For instance, it would allow L&T to combine their BIM with ecological impact studies. It would also allow them to minimize the cost.

Aligning geospatial with 4D BIM

Addressing the requirement to integrate GIS with BIM, L&T kicked off an initiative application to craft an in-house GIS-based platform to align geospatial and 4D BIM technologies. While other 4D BIM technologies provide updates on the series of events at the construction sites, L&T sought to include geographically-tagged data into their system.

Hexagon Geospatial, which provides an apt platform to design, develop, and deliver solutions that solve complex, real-world challenges, helped L&T to resolve this issue. The company chose Hexagon Geospatial’s GeoMedia to connect to their GIS, and perform dynamic queries and analysis of the data. GeoMedia WebMap provides a powerful online map of the whole site, communicating the location and availability of assets. All of this combined provided L&T a powerful tool for understanding the current status of the project and keeping it inside the guidelines.

The Enterprise Project Progress Monitoring Application provides a unified platform that assists in improved collaboration, transparency and efficiency from project planning all the way to execution. This environment acts as a ‘single source of truth’, making it a powerful and effective tool for construction progress monitoring.

Linear infrastructure projects can have widespread ecological impacts. These projects can extend deep into forests, adversely affecting whole ecosystems. Moreover, infrastructure projects represent huge investments, and any delay in project can result in immense cost overruns. Balancing these two concerns– minimizing the environmental impact and maximizing the cost savings — is a challenge. The new solution helps in managing both the ends.

Also, initially, the communication at client construction site was verbal. However, with GIS-based platform, communications have become easier. End users can simply login to the dashboard and geographically tag the work in progress along with other attributes like requirement of construction material, date and time the work has been completed, etc. The system helps to bring transparency at the construction site and monitoring of the manpower becomes easier by analysing the data/ information fed in the system.
Additionally, GeoMedia’s intuitive, dynamic analysis functionality enables concatenation of analysis processes. This results in one operation feed directly into the next process, as well as dynamic updating of results in response to data changes aided in building robust workflows for the project.

With special features of Login, users can be authenticated to avoid any frauds, thereby providing more reliable and effective results. Along with this, GIS helps in identifying the encroachment areas with visualizing the location based status. With GIS measurement tool, it becomes easier to map engineering drawing with the GeoMedia WebMap solution to ensure whether the infrastructure (rail, road, ports, metros) can be built or not, considering the exact location available.

By seamlessly integrating real-time locations of all the assets on the construction site into 4D BIM dashboards, L&T have latest data feeds available 24/7 for analysis and reports. This ensures enhanced planning and aids timely decision making, optimized resource allocation and better mitigation of risks. This provides a clear understanding of both “when” and “where” activities happen in their workflows.

The solution aims to maximize its application in the field of GIS and BIM in terms of integrating it with RFID, supply chain management, 3D GIS and BIM, seamless integration of 4D Schedule Integration and 5D representation of data with cost.

The Enterprise Project Progress Monitoring Application, a culmination of L&T’s thought leadership and technical expertise of Hexagon, is enabling L&T to manage its construction projects more efficiently as it empowers the stakeholders to take more effective decisions at the appropriate time.
