Connecting BIM and GIS
BIM (Constructing Info Modeling) and GIS (Geographic Info System) are two applied sciences with particular functions and use. GIS has mapping options and geographical databases, whereas BIM is particularly used for constructing belongings as an object-based data mannequin. The connecting hyperlink between these two applied sciences is gaining credibility in advanced and large-scale initiatives. Architectural and civil engineering initiatives often make use of BIM applied sciences whereas environmental initiatives are historically performed utilizing GIS techniques.
On this weblog, we’ll study all the advantages, and variations between GIS and BIM applied sciences and their makes use of.
Don’t have the time to learn the entire weblog, no worries you possibly can obtain it and browse it at your handy time.
What’s BIM?
3D depiction of Bodily and useful traits of constructing belongings.
BIM gives an built-in database for the constructing and infrastructure belongings that embody a 3d illustration of bodily & useful traits and geometrical knowledge of the related belongings. It’s a useful resource of data that’s shared and that helps doc administration, commerce coordination, workforce collaboration, and 4D development sequencing. It helps in decision-making all through the venture life cycle.
BIM Software program: Revit, Navisworks, AutoCAD 3D , Civil 3D and others
What’s GIS?
2D & 3D representations of geospatial shapes
GIS gives details about pure and constructed environmental belongings and different essential elements contemplating geography, demography, social financial system, and setting. It’s a system that collects, creates, integrates, manages, analyzes, and visualizes spatial knowledge utilizing maps. It helps customers perceive patterns, spatial relations, and geographic context. In the end, it helps environment friendly choices concerning the facility administration and operation & upkeep of these belongings.
GIS Software program: ArcGIS, CityGML, Bentley Maps and others
BIM and GIS
GIS informs BIM by offering the real-time knowledge of an asset’s current setting which helps designers and engineers to discover and consider the design and development. Moreover, an information-rich mannequin can be utilized to improvise all of the belongings inside a bigger space for operations and upkeep.
Integration of BIM and GIS builds a strong mannequin the place geographic and infrastructural design data are compiled collectively to ease the understanding of asset’s interplay and relation inside geography.
Utility of BIM-GIS Integration
The developed BIM-GIS mannequin consists of all details about utility infrastructure used through the planning, design, development, and operation phases. The appliance of BIM-GIS integration are the followings:
The BIM-GIS platform gives the geometric 3D visualization of every element that incorporates geometric data and semantic data. The visualization facilitates venture planning and execution. The visualization of geographic terrain, particulars on the terrain, surrounding services, floor and underground infrastructures could be realized within the GIS setting.
Operations and upkeep work are required both as a result of failure of utilities or in line with routine schedules. The BIM-GIS built-in mannequin gives able to us details about the utilities that can be utilized by the operation and upkeep workforce to determine the placement, sorts, and materials. Available details about the utility, making the system efficient, reduces time delays and value overruns.
Renovation and repairs actions are frequent through the operation phases. Historically, the utility data is both unavailable or is on the market in 2D CAD drawings. It is extremely tough to extract the precise utility data from 2D drawings that trigger a possible conflict between the utilities. On this BIM-GIS built-in platform, many BIM instruments comparable to Civil 3D, Navisworks, and GIS instruments comparable to ArcGIS present capabilities for conflict detection between the 3D utility mannequin. The 3D mannequin helps in offering data that may assist in additional actions.

Advantages of BIM and GIS Integration
- Maximize the returns from current funding in BIM & GIS software program
- Advance the understanding of extremely detailed geospatial context
- Allow collaborative workflows that easing the information reuse for all of the events concerned
- Make better-informed choices to speed up venture supply and enhance the operations and upkeep of accomplished belongings.
- Assist architects, engineers, and GIS groups work collectively extra successfully to place knowledge on the heart, take away silos, and join workflows.
- Allow architects and engineers to design smarter, extra environment friendly buildings and infrastructure.
- Gather and analyze knowledge from the sphere and enhance communication with key stakeholders.
- Join current techniques of report to create a federated supply of fact that helps reduce pricey errors and delays concerning important design choices.
Conclusions
Adopting 3D BIM processes and GIS applied sciences will largely profit the setting and remediation industries. It can open the door for more-inclusive stakeholder engagement, higher design high quality, and data-driven decision-making. Integration of BIM and GIS offered extra holistic and built-in workflows within the AEC industries to cut back price, and meet rising demand.
