think, exemplifying the intuitive nature and ease of which the information inherent in the model can be used for different design decisions.
and make informed decisions earlier in the process — helping to ensure the project’s success. •Using tools like the Revit BIM Portfolio and Navisworks risk is
Analysis features in Revit Architecture and Revit MEP means you can do earlier energy analysis and build a more sustainable design early on. • By using Revit and Navisworks
models, visualizing the project enables workers and owners know exactly what the project will look like (virtual fly throughs) and there is less risk of miscommunication, less chance of litigation. It is this accurate communication of design intent that delivers a huge benefit. phc: What is the future of BIM? Any new developments? Hodges: Let me touch on two

This fully-coordinated Navisworks model was used by Boston-based mechanical contractor J.C. Cannistraro for pre-fabricating the mechanical room at a laboratory facility in Cambridge, Mass.
phc: Can you explain the dynamic of
compatibility between the engineer/architect, builder and contractor? Hodges: This is a fascinating social
dynamic. Historically, the architects and design teams would create some wonderful design concept only to throw it over the wall and “dare” the contractor to build it. The relationships were very antagonistic. This is old school and no longer a sustainable way to work. BIM encourages and enables much better teamwork among all the disciplines. Complementing BIM, Integrated Project Delivery (IPD) encourages all parties to take greater ownership in the project. This shared ownership can often provide better costs, on time delivery and higher quality, which means a better project, has been delivered to the building owner. phc: It has been said that BIM usage reduces risk in the project. How?
Hodges: There are many ways
that BIM can reduce risk. We’ll mention just a few to start the conversation: • BIM is an integrated process
that vastly improves project understanding and allows for predictable outcomes. This visibility enables all project team members to stay coordinated, improve accuracy, reduce waste,
mitigated in many ways. Identifying clashes with Navisworks early on, means that you can identify errors, clashes and reduce expensive and time consuming RFIs, meaning you accept failing on the desktop and not in the field. It allows you to schedule work so that only the right personnel is on site, allows team to prefabricate MEP and reduce the number of site injuries. Using Conceptual Energy
areas. First, BIM has expanded beyond the focus of just buildings and now includes the civil engineering and infrastructure realm. The same principles that have improved the design and construction of buildings is now applicable for water, waste-water, power, smart grids and utilities, land development, road and
highway projects. Second, the whole concept on considering the entire “building lifecycle” is now being rolled into BIM. Eighty
percent of the cost of a building, over its lifetime comes after the building is constructed. This means the costs savings coming from electricity and water use, improved energy efficiency and maintenance are significantly greater financial considerations. High performance buildings are efficient buildings, delivering greater value to the owners and occupants.;
A construction-ready BIM is not only used for design, but can be utilized for estimating and project scheduling; as was the case at the large New England hospital shown above.
