Since the BIM-M Symposium a year ago, managers of BIM for Masonry projects have been working on documents and products to assist design and contractor communities in their efforts to incorporate masonry into the BIM environment, ensuring it remains the unparalleled wall system as technology continues to change the way the industry builds.
For the Design Community
BIM for Masonry–Modeling Masonry Buildings in Autodesk Revit was released this spring. Focus is on how designers can more easily incorporate masonry into Revit models. Information can be used to create plugins that will make it easier for designers to use masonry. A series of videos on masonry modeling based on information in the guide is available at bimformasonry.org.
BIM-M is also working with developer Cad Technology Center (CTC) to create masonry content for Autodesk Revit BIM software. Creating generic masonry content will immediately place it at the fingertips of the design team. This tool will make it easier for designers to use masonry. The deliverable is a generic Masonry Content Library with a plugin for Revit. The plugin will be posted for free on several industry websites. This should be available soon so watch for it on bimformasonry.org.
The Masonry Unit Database (MUD), under development, contains generic masonry materials that can be added individually or through the creation of material families. The database will be web-based and will work with AutoCad DXF, DWG, SketchUp Component, Rhino Block and Revit family formats. This Revit plugin will put masonry materials at the designer’s fingertips for use in models. Contractors are also eagerly awaiting the release. Having a generic database to draw from will allow them to get started in the modeling process more efficiently.
BIM Deliverables Guide for Mason Contractors
The Deliverables Guide demonstrates how modeling improves work processes and supply chain management.
These improvements will have a positive effect on the contractor’s bottom line. It was created based on information obtained from surveys conducted as part of BIM-M project 4, from contractors who were already creating 3D models for their own use and best practices of outside sources like the BIM Forum.
The BIM Deliverables Guide for Mason Contractors was introduced at the World of Concrete/ World of Masonry in Las Vegas in February. BIM-M had a booth in the Innovation Area sponsored by Spec-Mix, on Masonry Madness Day, there was a steady flow of contractors at the booth. We were fortunate to have Adrian Siverson of R & D Masonry of Marysville WA and Mike Giem of CAD BLOX, Lake St Louis MO, in the booth along with Darrell McMillian, technical director, Masonry Institute of St Louis and former BIM-M Contractor Input Project Manager and myself. Models that Siverson and Giem shared were good illustrations of the Deliverables highlighted in the Guide.
“Build It Before You Build It” identifying details, bond and coursing issues, as well as clash detection
Resources included are from a broad industry-wide context applicable to all facets of the industry, not masonry specific. One section explains the value of having a BIM Execution Plan. Another section shows samples of different BIM software with attributes of each. Deliverables and illustrations are from mason contractors or general contractors who self-perform masonry for the benefit of mason contractors.
Models and illustrations are meant to encourage contractors to transition to modeling their projects and to be clear examples of what kind of deliverables and information can be obtained.

- Material Quantities for purchase orders
- Shop Drawings
- Virtual Mock Ups
- Create Rfifor unworkable details/constructability issues
- Rebar size and placement
- Heights and coursing
- Lift drawings/ working drawings / work instructions
- Equipment and scaffold requirements
- Site logistics

The preceding information is the information part of the BIM process. The distribution list illustrates how contractors distribute information related to these deliverables. By creating a model for their own use, contractors can distribute this information to all appropriate parties. Dispensing this information allows for improved workflows which, in turn, improve the work processes that affect productivity.
Deliverables Generate Efficiencies
Material quantities can be used to manage the supply chain. From the model, it is possible to break down the quantities of a specific project by elevation. That information can be distributed to the foreman, material supplier and labor foreman. They can then use the information to create a delivery schedule based on the project schedule. Having the quantities by elevation for delivery schedule can minimize material handling, saving labor and minimizing breakage. The schedule can also be used for just-in-time deliveries, which can affect cash flow. The information can also be used to eliminate costly delays from shortages as well as eliminating costly overages. These are just a few examples of how some contractors are using material quantities from their models to improve work flows.

Creating Requests for Information (RFI) early in the construction sequence can have a positive impact on the work flow and work process. By modeling a project, the contractor is essentially building the project virtually before they build it in the field. Build It Before You Build It. The benefit is the contractor’s ability to identify details, bond and coursing issues, as well as clash detection in the modeling process. Rfican be generated in the startup / planning phase and shared with the CM/GC and A/E instead of waiting until the construction phase. If issues are identified and corrected in the startup phase, costly delays (work flow) and onsite out-ofsequence work or trade stacking (work processes) are eliminated.
Key to Growth
BIM-M makes it easier for the design community to incorporate masonry into a model and encourages mason contractors to participate in the BIM process. Participation is key to growth in the masonry industry. Participation not only makes mason contractors more productive and competitive, it illustrates to the other segments of the industry that masonry and mason contractors are eager to work with today’s technology and be part of the team.
