Implementation Support Group (ISG)

The Implementation Support Group (ISG) serves the various software implementation activities for buildingSMART standards. The mission of the ISG is to discuss and promote the use of bSI standards - Industry Foundation Classes (IFC), Model View Definitions (MVDs), the BIM Collaboration Format (BCF), and the buildingSMART Data Dictionary (bSDD) - enabling digital workflows for the exchange of built asset data among different software products and platforms. It is a peer-based forum, typical comprised of technical representatives from software vendors, representatives of the Model Support Group (MSG), Software Certification (SC), bSI Rooms (Building, Infrastructure, Airport, Regulatory, etc.) and guests.

Membership

Membership in ISG is open to all software companies that are members of the international, regional, or national chapters/alliances of buildingSMART. Members in good standing are encouraged to actively engage in events and activities sponsored by buildingSMART International and chapters, as well as the ISG, promoting the support for standards in their products and the value they bring to customers. Non-member companies are welcome as guests to observe ISG activities for up to a year before committing to buildingSMART membership and active participation. Academic guests are always welcome to observe and engage to help broaden the communication of technical expertise between research and industry realms.

Current active members include representatives of the following companies:

  • AEC3
  • ALLPLAN
  • Arkey Systems
  • Autodesk
  • Bentley Systems
  • CADline
  • coBuilder
  • Dassault Systèmes
  • Data Design System (DDS)
  • GRAPHISOFT
  • IES
  • Obermeyer
  • Progman/MagiCAD
  • SCIA
  • Solibri
  • Trimble
  • Vectorworks

Activities

ISG organizes regular, biannual, in-person meetings (Spring and Autumn), at locations hosted by members on a rotating basis, and monthly online/telephone conferences to discuss implementation and support strategies and to clarify issues occurring among members.

In detail, the ISG's activities include:

  • Supporting and coordinating implementation of buildingSMART standards and technologies between software implementers in all markets;
  • Providing a peer-based forum to exchange experiences, discuss technical issues, and resolve non-compliance with requirements;
  • Monitoring and distributing information to member vendors from bSI leadership, the MSG, the SC, the Rooms, and any other sources of end-user needs and requirements. This includes reports from the biannual bSI Standards Summits, trade shows, and conferences with relevant buildingSMART activities;
  • Promoting software implementation through demonstrations and prototyping of new ideas and upcoming requirements;
  • Facilitating the certification process for IFC support in software, together with the MSG and SC;
  • Monitoring standards implementation activities, in various international markets, around bSI standards and technologies, especially creation and adoption of Model View Definitions (MVDs) and BIM deliverable requirements;
  • Representing member software vendors and their interests within the buildingSMART community and industry at large.

Subgroups

As a whole, the ISG brings together vendors which include support for many different domains of the design, procurement, fabrication, and operations of the built environment. This currently includes building disciplines of architecture, structural, and building services (aka MEP) design, as well as the new infrastructure realms of roads, railways, bridges, tunnels, ports, harbors and more. Core standards and technology concepts are important to all these domain vendors, but there is value in recognizing and proactively addressing differences.

In acknowledgement of the support for many processes and workflows with different data exchange requirements that occur throughout the lifecycle of a project, there are focused subgroups of ISG that target the particular areas of the interoperability challenge. These subgroups currently include:

  • Buildings - including architectural, structural, and building services [MEP] design
  • Structural design, simulation, and analysis (multi-domain)
  • Infrastructure

Additional interest in new sub-groups include:

  • Building energy modelling, simulation, and analysis
  • Facility/Asset management and operations

Ad-hoc Task Groups

The ISG will form Task Groups on an ad-hoc basis, consisting of representatives of member vendors, to address larger issues or directives of the ISG. Such Task Groups might include analysis of specific implementation issues like the best IFC representation of reinforced concrete design elements, prototype usage of product libraries, or proposals to enhance current standards, such as BCF.
