Digital models have many benefits
for construction; for example, clash detection prior to approval, ability to confirm assembly sequencing, verification of
as-built dimensions, and more. Customizing and preparing such models for project delivery takes a large amount of time
and, unfortunately, cannot guarantee that the physical building or part can be built as modeled; a disconnect between design
intent and constructability can often occur. One reason for this is that design team is unaware of certain details that are
involved in fabricating and assembling building components; an understanding that craftsmen take for granted. This
paper presents the process of incorporating Autodesk Revit into the workflow of an architectural precast concrete manufacturer,
tracking a real-world project from design intent model through the incorporation of industry-specific fabrication details.
Methods used to generate a novel digital model, as well as to produce shop drawings and shop tickets from that model are documented.
Three approaches to creating customized Revit models are described: using parametric Revit families; through Dynamo scripting;
and via Excel spreadsheet input. Future potential workflows which could extend the findings even further are discussed,
setting the groundwork for "Design-Assist", an emerging project delivery approach wherein subcontractors are
engaged early in project development to provide advice to the design team, allowing for more informed decisions, conversations,
and digital models for construction. The work was presented at the 2016 International Symposium on Automation and Robotics in Construction (ISARC). Click here for a PDF of the full paper.
