publication of IDM (International Organization for Stan- dardization [ISO], 2010), IDM has been used in various projects for information delivery, such as precast concrete (Panushev, Eastman, Sacks, Venugopal, & Aram, 2010), geotechnical design and analysis (Obergriesser & Bor- rman, 2012), and heating, ventilating and air conditioning (HVAC) design (Liu, Leicht, & Messner, 2012; Liu, Akinci, Berges, & Garrett, Jr., 2013). There are 101 IDM docu- ments under the development by national organizations and company groups, and four IDMs have been approved (buildingSMART, 2013). Some researchers have also tried to implement infor- mation exchange by integrating IDM and MVD. Lee, Park, and Ham (2013) proposed an extended Process to Product Modeling (xPPM) method to define IDM and MVD. The xPPM method could produce the IDM by using existing ERs and Functional Parts (FPs), and resolve the mapping between IDM and MVD. Lee, Eastman, and Solihin (2016) proposed an ontology-based approach to define accurate data modules for model views, and translated ontology- based IDM from OWL/XML to mvdXML. Some MVDs related to specific domains are being developed. Ramaji, Memari, and Messner (2017) extended current available MVDs to support information delivery of multi-story modular building projects. Pinheiro et al. (2018) pro- posed an MVD-based method of information exchanges between BIM models and building energy performance simulation information. In the AEC industry, some exist- ing commercial software tools can be used for BIM col- laboration, but they may not be able to support specific user-defined ERs of information delivery (Rezgui, Beach, & Rana, 2013). To date, 29 MVDs have been submitted to IFC Solutions Factory (BLIS, 2018), such as architec- tural design to structural design and structural design to structural analysis, but partially supported by commer- cial software tools. For example, Revit 2018 is capable of exporting IFC models based on a set of MVDs, such as IFC2x3 Coordination View, IFC2x3 Basic FM Handover View, and IFC4 Reference View. In the structural domain, the CIMsteel Integration Standards (CIS/2) is the product data model for structural steel projects. To import struc- tural steel information to other BIM applications, CIS/2 models need to be translated into IFC models (Lipman, 2009). It shows that the MVD related to the delivery of structural design for collaborative design is not yet defined in practice. Although some methodologies were developed for IDM and MVD, they have not been easily implemented as expected (Kiviniemi, Tarandi, Karlshøj, Bell, & Karud, 2008). Some challenges of the implementation of IDM and MVD are summarized as follows: – IDM and MVD seem to be complementary to each other. However, the boundary between IDM and MVD is blurred (Aram, Eastman, Sacks, Panushev, & Venugopal, 2010), easily leading to duplication ef- forts in IDM and MVD (Lee et al., 2013).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
