The Building Information Modeling for Masonry Initiative (BIM-M) is an international effort of the masonry industries in the United States and portions of Canada for identifying barriers to and strategies for the full implementation of masonry materials and systems into BIM software for the design and construction industries. The purpose of our initiative is to unify the masonry industry and all supporting industries through encouraging the development and implementation of BIM for masonry software to facilitate smoother workflows and collaboration across all disciplines from owner, architect, engineer, manufacturer, mason, contractor, construction manager, and maintenance professionals.

Our commitment to BIM-M is an indication of the professionalism and dedication of the masonry industry to the modernization of the construction industry.

The initiative is sponsored by the International Union of Bricklayers and Allied Craftworkers (IUBAC), the Mason Contractors Association of America (MCAA), the International Masonry Institute (IMI), the National Concrete Masonry Association (NCMA), the Western States Clay Products Association (WSCPA), the Brick Industry Association (BIA) and The Masonry Society (TMS) and is being guided by the Digital Building Laboratory at the Georgia Institute of Technology.

Our stakeholders are expected to benefit greatly from the integration of masonry into the next generation of BIM tools, such as:

Building Owners

Information for understanding life-cycle costs of ownership; record keeping for tracking maintenance and upkeep; tools for creating and maintaining as-built drawings.


Design tools, methods for quickly importing masonry details and product models into BIM authoring tools; uniform language and classification systems for masonry units and assemblies; tools for describing air, thermal, moisture and vapor control layers within BIM models; tools for cost estimating while in the programming and schematic design phase.


Tools for sharing information with architects and converting design information into structural analysis models (2-D and 3-D); means for generating and applying masonry details to models.

Manufacturers and Suppliers

Ability to create standard building product models with specifications; improved access to procurement and supply requirements and E-commerce platforms; links to MRP (materials requirements planning) and EPD (environmental product declarations).


Opportunities to reclaim and expand market share; data sharing for increased safety and productivity.

Mason Contractors

Increased opportunities for promoting masonry construction; tools for interactive scheduling and coordination; safety management tools; interoperability tools for improved communications with architects and engineers and construction managers.

Construction Managers and General Contractors

Interactive scheduling, quantity takeoff and coordination tools; safety management tools; tools for improved communications with mason subcontractors, enclosure subcontractors (glass, concrete, roofing, etc.), structural steel subcontractors, architects, engineers and owner; planning tools for site logistics and lean construction.
