Michael Rendler is the Director of e7 Architectural Studio which is a non-profit organization working with the Los Angeles Community College District (LACCD). Its goals are to assist in designing environmentally sound and sustainable additions to current and future campuses. Michael gave a fascinating overview of how 3D models for all the buildings on LACCD's mulitple campuses were developed.
The LACCD is the largest community college district in the United States and serves more than 250,000 students annually at nine colleges, spread throughout 36 cities in the greater Los Angeles area. About eight years ago it was decided to initiate a project ro create 3D BIM models of all the buildings on the LACCD campuses. One of the most important motivations for creating these models was that BIM models would faciliate energy performance analyses of LACCD buildings.
There are several very interesting and unique aspects to the development of these models. First of all the models were created entirely by LACCD students. Existing structures were laser scanned and BM models were developed from the point clouds.
Secondly, to ensure a uniform representation of all the buildings across all of the campuses, it was decided to adopt standards wherever possible. The standards used include IFC, SDSFIE, OMNIClass, and COBIE.
Thirdly, the BIM models were stored in a geospatial database (Oracle Spatial) using real world coordinates. Real world coordinates enabled the models to be easily integrated with geospatial data from a variety of sources.
The models could then be used for a variety of purposes including visualization, energy performance modeling, predictive maintenance, and safety and security simulations.
For the safety and security simulation the models were brought into a gaming environment to allow gamification of safety procedures.
