Building Information Technology in AV

Building Information Modeling is a 3D design, modeling and simulation technology for the architectural, engineering and construction industries.  While not new — elements have been around for several years — it is an important initiative that is changing standard practice in architecture today.  So what does it do?  Primarily, BIM is a shared knowledge resource between everybody involved in the design process — architects, engineers, interiors people and other contractors and sub-vendors, including audiovisual professionals — for information about a facility and the building materials incorporated into it.  The building industry has embraced the evolution of 2D drawings and analog text to digital electronic imagery and information. For the architect, BIM is a very useful tool as the technology allows them to be better designers — they can deliver projects faster, easier, greener, on-time and often, under budget. Other beneficiaries of BIM include facility owners, planners, appraisers, estimators, environmentalists, real estate agents, lawyers, code officials, and ultimately, building occupants. BIM has changed the way structures are designed because it provides a much better interpretation of what the building is going to look like and how the building will perform over its life cycle. While the definition of BIM begins with the 3D modeling of the entire building, each design phase includes the architecture, mechanical, electrical, plumbing, and every component of the project that requires physical coordination. But it’s the “I” in BIM that is most beneficial. The building elements are represented in both graphical and data-rich text so that the information or data embedded behind each BIM object is available to be shared. Features such as size, shape, color, fire-rating, warranty, raw materials, manufacturer’s specifications and other documentation can be included for each product in the model.

Informational Insight

BIM is widely known in the United States, and as more projects are being designed abroad by stateside architectural firms, BIM is gaining ground globally.  For the audiovisual industry, the significance of BIM lies in the fact that in the eyes of a construction professional, AV manufacturers are building product manufacturers, not AV companies. AV technologies can greatly impact the performance of a building and can be beneficial to the health, safety, welfare and productivity of building occupants. Information in the BIM building model can be very helpful to AV providers. First, the ability to visualize within the 3D imagery the physical aspects of the AV products incorporated into the space — such as video display size and location, loudspeaker configurations, projector mounting locations, equipment rack layouts, and head-end equipment locales — is very valuable. To be able to share all of that information in collaboration and coordination with architects, interior designers and other construction professionals is beneficial in several ways. BIM facilitates clash detection and design flaws, so space and system-routing conflicts can be identified, as well as ascertaining clear cable pathways and projector and camera sightlines. Visual simulation can also detect potential problems, such as natural daylight designs that compromise video display clarity. Control system software can be coordinated within the model so that the control system can be effectively demonstrated for multi-media, volume, lighting, projection screen and HVAC applications.

Again, the data imbedded behind each audiovisual BIM object could also include environmental information about the product such as recycled content or low volatile compounds (VOC) that was used in the manufacturing process. This could help determine implications of “green” initiatives for Leadership in Energy and Environmental Design (LEED) certification requirements. BIM tools offer analysis of the performance of energy efficiency elements and sustainable materials.

Benefits of BIM Beyond the Construction Phase

Once the building is completed, facility management professionals can rely on BIM’s potential lifecycle analysis, performance assessment and routine maintenance. BIM can be considered as a “digital owner’s manual” for the building. The BIM model stays with the structure for its entire life. AV products in the model can be accessed for product information, warranty, operational and trouble-shooting procedures as well as establishing additional components needed for future upgrades should application requirements change.

BIM is embraced by about 85 percent of design firms, and there are some organizations and governmental institutions that have mandated BIM. The GSA, NASA, and several states such as Texas, Wisconsin and Ohio have mandated BIM for construction projects.  General Motors, Intel, Walt Disney and even the retailer Crate & Barrel require BIM for new builds.

Earlier Involvement

AV professionals will soon recognize that BIM will affect their world. At the least, BIM projects will require that AV is involved earlier in the design process. That can be a real advantage for AV product manufacturers, consultants, and system integrators alike. Traditionally, AV has been an afterthought, but now with BIM, it’s an integral aspect of the structure. That makes life easier for the architect as well.

With significant time and cost reductions, elimination of construction conflicts and more accurate estimates, BIM will help architects and AV professionals work together more effectively, by being on the same page throughout the entire building process.
