San Francisco Digital Model
(conclusion)

The accuracy of the buildings—such as their heights and details of form, among other data—varies throughout the model. To make sure that the model can be used with confidence now and in the future, metadata that describes the source, accuracy, and level of geometric detail is embedded into the building models. SOM can also update, add to, and correct information in the model to continuously improve its accuracy.

To date, SOM has used the Digital Model in the design of numerous projects in San Francisco, ranging from individual buildings to entire neighborhood plans. The Model allows SOM to analyze its work in the City in relationship to its surroundings. For example, SOM can overlay information in the Model such as San Francisco’s seismic liquefaction zone, possible increases in sea level due to global warming, and wind, fog, and shadow patterns. Additionally, any information tracked by San Francisco’s Geographic Information Systems, such as land use in the City, can be applied to the model.

Wind analysis is one of the most frequently used applications of the Model because it allows SOM to quickly simulate the wind impact of its projects earlier in the design process.

The Digital Model can be easily translated into material 3D models (3D prints) of various scales, providing a detailed physical representation of SOM’s projects within the context of San Francisco’s urban landscape.

SOM San Francisco will continue to bring greater depth and interactivity to the Digital Model by adding geospatial information and linking buildings to other outside sources.
