210 King St East Revit Model
June 17, 2009

Revit Model 1

The development of a BIM model for 210 King required a different approach than what could be expected from the BIM process for new construction. Critical elements needed to be discovered and identified rather than drawn and detailed, structural ambiguities had to be resolved empirically rather than inferred from construction drawings, hidden wall sections had to be assumed rather than be assembled. In the case of 210 King which involves the interaction of 4 buildings built at different times, the interaction between the buildings themselves had to be understood beyond simple connecting blocks. But above and beyond this, the nature of the approach to understanding this heritage building in terms of BIM was very unique.

The process was hampered by unknown wall compositions, surveying inconsistencies, various sets of blueprints and plans that did not match, and ambiguous interactions between elements which could not be discovered without actually ripping holes in the walls. The use of BIM 'families' had to transcend their usual purpose as reusable building elements; instead, 'families' were often used to connect the standard elements to the adhoc maintenance and repairs which occurred over the life of the building. Whether or not this extended use of families will cause an issue in the future simulations is unknown at this time.

The main difference between BIM for existing construction and BIM for new construction is that existing architecture has a life story – it has experience and exists in time. All of this is etched in its architecture, its maintenance, and its inhabitation. By going through this process, some discoveries were made that helped the building communicate its story. For 210 King, the process of creating the BIM dataset had the added effect of revealing the story embedded in the architecture.

Read the complete case study, which details the approach and process used to develop the BIM model, as well as some of the difficulties encountered along the way.

Revit Model 3

The preliminary version of the Revit model is available for download below. The model includes the exterior walls, foundation walls, roof, and roof deck; interior walls and floors; circulation including elevators and emergency stairs; entrances and exits; windows, doors, and other openings; structural system (beams and columns); and 'room' boundaries and 'space' boundaries for sustainability simulations.

We will be refining and adding to the model in the near future, so check back for updates.
