9 likes8,943 views
The document discusses a webinar on integrating Building Information Modeling (BIM) with Computer-Aided Design (CAD) and Geographic Information Systems (GIS), highlighting workflows, tools like FME, and case studies including an airport project. It emphasizes the challenges of data complexity and interoperability, and how FME can streamline the extraction, transformation, and loading of data across various platforms. The webinar also covers future potential applications of BIM, including infrastructure and building modeling, and provides resources for further learning.

- 6. Why use BIM? ➔ Digital representation of infrastructure: both building information and 3D ➔ Includes descriptive info (dimensions, materials, manufacturers, etc.) ➔ Aids in proper design, construction, operation, maintenance & updates ➔ Drawback: files size and complexity make data difficult to repurpose
- 7. Why use GIS? ➔ Map and analyze geographic features ➔ Uses location and imagery ➔ Conveys data on a large scale ➔ Data models, attributes, simple geometries, and domains
- 8. Why extract from BIM? ➔ Visualization planning, site suitability ➔ 2D floor plans routing, maintenance ➔ Analysis space management: scheduling / leasing, energy / HVAC ➔ Construction management as built vs design ➔ Facilities management maintain and replace components, work plans, reporting ➔ Updates keep BIM current, add reference links
