Phase III - Structural Engineering and BIM-M

In a conventional design workflow, structural engineers take building data in the form of plans and elevations from the architect, and assess the initial architectural design ideas for gravity and lateral loads. The engineer uses manual or computational analysis to design the walls, and returns information to the architect on the extent of walls (for in-plane and out-of-plane loads), reinforcing requirements, control joint locations, etc. In a BIM-enabled masonry workflow, structural engineers will receive a BIM model from the architects with potential wall locations identified. Structural engineers will be able to select walls that are to be load bearing (for gravity loads), resistant for lateral loads (shear walls) and non load-bearing walls.

This project will establish the workflow for BIM integration between architects and structural engineers. The information exchanges needed to transfer wall information from the architect to the structural engineer and from structural engineering BIM directly to structural analysis will be established. This project will build on the previous Masonry Wall Model Definition project. It is anticipated that the BIM-M Executive Committee and the DBL will develop an RFP for this project, and that the project will be bid to interested parties in the educational and software development community. The project will build on prior work sponsored by the IMI and NCMA to implement masonry wall structural analysis software in Bentley RAM. The project will also survey existing stand-alone masonry wall software to assess its potential interactivity with BIM- M.
