Abstract: Previous efforts by the US Army Engineer Research and Development Center, Construction Engineering Research Laboratory (ERDC-CERL) to develop a life-cycle building model have resulted in the definition of a “core” building information model that contains general information describing facility assets such as spaces and equipment. To describe how facility assets (i.e., components) function together, information about assemblies of assets and their connections must also be defined. The definitions of assets, assemblies, and connections for the various building-information domains are discipline-specific. Work documented in ERDC/CERL CR-13-2 identified the processes and tasks specifically associated with the design of building electrical systems and the information exchange requirements for every participant in the design. The findings were used to develop an information-exchange Model View Definition (MVD) for building electrical systems. The objective of the current work was to document the steps needed to identify the electrical MVD attributes in three experimental building information models representing typical low-rise Army facilities, and to update the models. This work also validated the International Foundation Class (IFC) export function from the experimental models against the electrical MVD, and studied the requirements for creating computable open building models that can be utilized for the automated information exchanges.
