LOD – Level of Development buildingSmart International
The Level of Development (LOD) Specification is supposed to provide clarity and reliability with respect t0 Building Information Models (BIM/BIMs).
On the good side, CSI UNIFORMAT II is used as a means of organization. LOD is intended to define characteristics for building systems relative to BIM elements. In theory, the goal of the LOD specification is to clarify what BIM “models” can be used for and their associated limitations, for both current and future users.
The issue, once again, is the lack of focus upon business processes and efficient collaborative construction delivery and required asset life-cycle modeling competencies. There is little use for
“standards” if they sit in isolation.
Any discussion, use, or development of LOD must be within the context of a BIM execution plan and/or BIM Operating Manual.
Most importantly, the initial and excessive focus upon 3D visualization (QTO, 3D coordination, and 3D control and planning, is once again “off the mark”. LOD should have a sound foundation in asset life-cycle modeling and LEAN construction delivery, as well as all associated competencies.
Perhaps, when Architects, Engineers, Contractors, Owners, and Business Product Manufactures actually collaborate BIM will actually gain measurable traction towards its true purpose.
