Mastering Autodesk Revit Architecture 2016. Krygiel Eddy

      The role of the architect is to generate the design intent and manage the technical issues of the project. As the model is being created, you will naturally have to solve issues like constructability and wall types and managing the program of spatial and equipment requirements, as well as other issues involving code compliance and client relationships. This role will be the one applying standards to the project (as in wall types, keynotes, and so on) and organizing the document set. This role will need to be present on the project from the beginning to ensure consistency of the virtual building creation and isn’t necessarily limited to only one person. This role also might or might not be a “designer.” Although it is possible to do early design in Revit software, many project teams prefer to use other tools such as SketchUp or even a pencil and tracing paper. The job of the architect is steering the creation of the building within the Revit environment. This role includes the following tasks:

      The role of the modeler – in some firms referred to as the BIM coordinator – is to create and manage the 3D families and detail components needed in the project, which include all the parametric families for things such as windows, doors, casework, wall types, stairs, railings, furnishings, and so on. Typically, this role is the responsibility of less-experienced staff who might not be able to fulfill the role of architect. This role tends to have longer periods of undisturbed time, making it better suited to deal with some of the longer, more involved tasks in modeling content. Finally, it also tends to have some familiarity with modeling applications from academia or prior work experience. The modeler might not have worked with Revit software directly but possibly with 3ds Max software or Rhino. This role includes the following tasks:

      The role of the drafter is to create sheets and embellish associated views with annotations or other 2D content. The drafter is responsible for the bulk of the work needed to document the project. In earlier stages of the project, this role is typically assumed by either the architect or the modeler, but as documentation progresses into later phases of design, this can quickly become the role of multiple people on a larger project. This role includes the following tasks:

      To optimize your results with BIM, it’s important to start with the end in mind. Although a lot of tasks are possible with a BIM model before you draw your first wall, you will want to create a BIM execution plan. We go into more detail about creating these plans and some resources for them in Chapter 6, “Working with Consultants,” but essentially a BIM plan helps to drive the direction of the modeling effort and modeling outcomes. Will your project need to add parameters for energy modeling? Daylighting? Does the owner have expectations for a model deliverable? How much does everyone model without being too much? All of those possibilities and more are explored and documented in a BIM execution plan. It gives the project team a definitive outcome to model toward.

      The BIM plan will also help address which team members you’ll need at which phases of the design. For instance, 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 workflow, 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.

      In many projects, there might come a time when the schedule gets tight and project management wants to add more staff to meet a specific deadline. When in a 2D CAD environment, new team members would be added to help meet a deadline and would have the burden of trying to learn the architecture of the building, the thoughts behind its design, and how its various systems interact. In a Revit project, they have that same obligation, but they have the additional task of learning how the model has been configured. The model will have constraints set against various elements (such as locking a corridor width) and various digital construction issues (such as how floors and walls might be tied together, what the various family names are, or workset organization). New team members require additional time to “ramp up.”

      Regardless of planning, deadlines still escape the best of architects and project managers. It’s a good idea to know when and how you can “staff up” to be sure to meet those deadlines. Keeping in mind that your team members new to the project have to learn about both the design and the model, here are some task ideas to both help production and make sure they don’t accidentally break anything:
