Establishing an Appropriate Level of Detail (LoD) for a Building Information Model (BIM) – West Block, Parliament Hill, Ottawa, Canada
In 2011, Public Works and Government Services Canada (PWGSC) embarked on a comprehensive rehabilitation of the historically significant West Block of Canada’s Parliament Hill. With over 17 thousand square meters of floor space, the West Block is one of the largest projects of its kind in the world....

| description | In 2011, Public Works and Government Services Canada (PWGSC) embarked on a comprehensive rehabilitation of the historically
significant West Block of Canada’s Parliament Hill. With over 17 thousand square meters of floor space, the West Block is one of
the largest projects of its kind in the world. As part of the rehabilitation, PWGSC is working with the Carleton Immersive Media
Studio (CIMS) to develop a building information model (BIM) that can serve as maintenance and life-cycle management tool once
construction is completed. The scale and complexity of the model have presented many challenges. One of these challenges is
determining appropriate levels of detail (LoD). While still a matter of debate in the development of international BIM standards,
LoD is further complicated in the context of heritage buildings because we must reconcile the LoD of the BIM with that used in the
documentation process (terrestrial laser scan and photogrammetric survey data). In this paper, we will discuss our work to date on
establishing appropriate LoD within the West Block BIM that will best serve the end use. To facilitate this, we have developed a
single parametric model for gothic pointed arches that can be used for over seventy-five unique window types present in the West
Block. Using the AEC (CAN) BIM as a reference, we have developed a workflow to test each of these window types at three distinct
levels of detail. We have found that the parametric Gothic arch significantly reduces the amount of time necessary to develop
scenarios to test appropriate LoD. |
