BIM FOR MULTIPLE DISCIPLINES
Delta Township Assembly
Complex
General Motors/
Ghafari Associates, LLC
General Motor’s Worldwide Facilities Group
is applying 3D Virtual Factory Initiative (VFI)
solutions for the design, coordination, and
construction of the new Lansing Delta
Township Assembly Complex in Michigan.
The project includes a new body shop, an
assembly plant, connecting trestles, an administrative building, and an arrival center. Cost
of construction is $500 to $800 million.
The project used a design/build delivery
method with a collocated team. Throughout
the design/engineering phases, the entire
design/build team, including GM’s project
engineers, collocated at the offices of Ghafari
Associates, in Dearborn, Mich., the lead architect/engineer for the project.
The project is being designed and coordinated throughout the construction phases using
3D-enabled technologies and lean workflows. Ghafari Associates used GM’s strategic
facilities 3D solution based on Bentley’s
TriForma-based applications, GEOPAK, and
PlantSpace Design Series to design, coordinate, and produce many of the 2D coordinat-
ed construction documents for MEP systems.
The firm was able to help decrease re-work
and increase the quality of the 3D model by
implementing workflows and procedures to
incorporate structural 3D analysis data direct-
ly into the 3D models. Similarly, when the 3D
steel fabrication models became available,
the fabrication models were imported from
the fabricator’s 3D models into the master
design models for further coordination using
Bentley Structural’s steel direct data
exchange capabilities. ;
