The chapters in Part 1 are devoted to rounding out that knowledge and helping to fill in any of those gaps in your knowledge of the toolbox, the UI, or the Revit workflow.

Chapter 1 Beyond Basic Documentation In this chapter, we’ll cover some of the principles of a successful building information modeling (BIM) approach within your office environment and summarize some of the many tactics possible using BIM in today’s design workflow. We’ll explain the fundamental characteristics of maximizing your investment in BIM and moving beyond documentation with the BIM model.

Leveraging the BIM Model | 5 As the technology behind BIM continues to grow, so does the potential. There are a host of things now possible using a BIM model; in fact, that list continues to expand year after year. Figure 1.3 shows some of the potential opportunities. When moving to the next step with BIM—be that better documentation, sustainable analysis, or facility management—it’s important to identify where you land in three primary goals for your use of BIM.
| Chapter 1 Beyond Basic Documentation We’ll first define each of these areas individually and then discuss what it means to begin combining them in practice. Visualization Creating documentation using BIM has the added advantage of being able to graphically visualize the project in 3D.

Leveraging the BIM Model | 9 This same workflow is true for daylighting (Figure 1.8) and several other types of building performance and design analysis. By being able to repurpose the Revit model geometry, we are able to lose many of the “rules of thumb” we have created as designers along the way and begin to rely on calculated results. The Revit model also ensures consistency and accuracy of design through analysis by using the model as the sole point source for design geometry. Figure 1.

Modeling techniques and workflows will need to be established. Analysis-based BIM requires different constraints and requirements than a model used for clash detection.
Leveraging the BIM Model | 11 these new ideas a bit before adoption. In late adoption, the I in BIM is not critical. Information within the model will be used for documentation (i.e., door schedules), but analysis will probably be done using different model sources. Figure 1.10 Late adoption V S A Intermediate Adoption Intermediate adopters, as shown in Figure 1.11, tend to assume a much stronger relationship between visualization, analysis, and strategy.
| Chapter 1 Beyond Basic Documentation How BIM Affects Firm Culture In understanding where you are and where you want to be in this adoption curve, it’s also important to understand that moving between any of the iterations of this curve requires a shift in your internal firm culture. As anyone who’s adopted BIM can tell you, the difficulties you might experience do not come from learning a new application but understanding how that application affects your workflow—and managing that change.
Focusing Your Investment in BIM | 13 what you are trying to manage—either personally or for your project team—is this predictability versus innovation while trying to maintain a level of happiness and morale. Evolution vs. Revolution While you’re in the process of trying to manage the amount of change you’re willing to endure, you also need to consider the rate that change will affect your project teams.
| Chapter 1 Beyond Basic Documentation that down to even a 10-person firm, and if you apply the same one percent, that becomes one person’s time for three full weeks. The key to optimizing this 1 percent investment is focusing the firm’s energy and resources. As the technologies behind BIM continue to expand, so do the opportunities for specialization, so you will need to pick and choose strategically to focus the efforts and direction of your firm.
The Bottom Line •u Programming •u Facilities management •u Asset tracking •u Trending | 15 If the investment (regardless of scale) is focused and planned, it can still leverage strong potential. Identifying the importance of visualization, analysis, and strategy to your firm and process will help guide you in selecting areas of focus within your own practice. When choosing the specialization or how much focus to give to visualization, analysis, or strategy within BIM, there are no wrong answers.
