Now let’s apply these roles to the project timeline. If you look at a typical project process, outlined in Figure 1.13, you see Time on the x-axis and Effort on the y-axis. Superimposed on this chart is the curve that represents the effort in a BIM workfl ow demonstrating labor intensity at various times of the project cycle. We have also taken the roles of architect, modeler, and drafter
and shown them in the graph represented by the numbers 1, 2, and 3, respectively.
From a work-planning purpose, we are demonstrating the ideal times to implement these roles. At the inception of a project design, a modeling role will be of the best use. This person can help create building form, add conceptual content, and get the massing for the building
established. If you’re using the conceptual modeling tools (covered in Chapter 8, “Advanced Modeling and Massing”), the modeler can even do some early sustainable design calculations
(covered in Chapter 9, “Conceptual Design and Design Analysis”).
Once the project begins to take a more established form and you complete conceptual design,you’ll need an architect role to step into the project. As in a typical project, you’ll have to mold the form into a building by applying materials, applying wall types, and validating spatial
requirements and the owner’s program.
During schematic design, you’ll need to include the role of the drafter to begin laying out sheets and creating views. These sheets and views don’t have to be for a construction document set as of yet, but you’ll need to establish views for any schematic design submittals. If these views are set up properly, they can be reused later for design development and construction
document submittals as the model continues to gain a greater level of detail.
You should avoid adding staff to your project during the construction documentation phase.
In a BIM/Revit workfl ow, this can sometimes cause more problems than it solves and slow down the team rather than get work done faster.
Another proven technique of managing larger Revit projects is to assign work according to
elements of the building rather than by drawing a series. For example, one person would be
responsible for building enclosures and another for structure, interior partitions, furniture,
vertical circulation, and so on. This strategy encourages each team member to develop their
portion of the design more collaboratively because the modeling for each component must be
coordinated with the surrounding systems
Even though your team won’t be assigned work through a series of sheets, each person
should be tasked with overseeing each sheet series. The annotation related to each building
system is the responsibility of the respectively assigned team member, but someone else will be
responsible for reviewing each series of sheets to ensure that they are appropriately maintained
for presentation or distribution. On smaller projects, the project architect would likely be the
person supervising the entire sheet set.
This dual responsibility is an important aspect of team management that will keep your BIM
projects on track. Spending the majority of time working in the model and thus neglecting the
preparation of properly annotated sheet views becomes very alluring.
