BIM Building Information Model

1. BIM Building Information Model

2. BIM: A New Dimension For Buildings Electronic drawings have become a common building-design deliverable from architects to their clients once construction projects reach completion. Sure, discs and electronic files are easier to store than drawers of paper drawings. But otherwise, these bits and bytes (and various pieces of software) have, for the most part, yet to live up to many of the promises made when computer-aided design (CAD) first hit the market—almost two decades ago. Now, though, design software is in the process of making its next great leap. Current 3D modelling capabilities are expanding to provide a virtual database of all information related to a building’s construction and performance. This technology, called “building information modelling” (BIM) is still in its infancy. But, at this early stage, facilities owners are beginning to understand BIM’s potential value.

3. Potential contractor conflicts are identified ahead of time—and avoided. BIM provides all the virtual-walkthrough capabilities of today’s advanced 3D designs. Many construction projects have been improved via the relatively simple change of incorporating scheduling information into a BIM database. With this, a fourth dimension—time—is incorporated into the model. Result - A BIM with this scheduling information can help all those involved in a project (architects, engineers, general contractors, and subcontractors) to visualize the day-by-day progress of a given project. With this, the building team can monitor—in advance—an animated version of the planned construction process. Net: Potential contractor conflicts are identified ahead of time—and avoided. Proponents say that a typical BIM, at some future date, will incorporate information on each piece of equipment and system within the building (including performance data) before the first worker gets to his or her desk inside. Bottom line: A true BIM will be a virtual version of its bricks-and-mortar counterpart. What’s more, facility managers will be able to update the virtual model as the actual building is modified…so the 3D “virtual” building remains an exact replica of the actual structure.

4. Evolution, not revolution One key to faster progress for BIM is that the information that now goes into designing, constructing, and maintaining a building already exists in electronic form, somewhere. From drawings to bid documents and purchase orders, electronic records have become a part of almost every project today. BIM’s promise is to bring these drawings and documents together, into a single database that can be referenced easily throughout the building’s lifespan. Why do this? In addition to upfront construction-cost reductions, intelligent use of a BIM could mean big savings for facilities owners over time. Getting the right replacement part for a failed HVAC component, for example, could be as simple as clicking on an image of the part within a BIM to find out manufacturer and model information. Maintenance history Maintenance history could be tracked just as easily. What’s more, for many buildings, whenever a renovation is contemplated, there is an all-too-common futile hunt for accurate as-built drawings. Obtaining a BIM upon delivery of the building and updating it over time would mean the building’s 3D model would be up-to-date and accurate. Result: Bids for renovation projects could be developed with a high degree of accuracy.

5. A sophisticated database BIM for a Greener Building Building information modelling (BIM) certainly offers great possibilities for speeding up construction schedules and cutting construction budgets, as a result. Proponents of this new technology also believe it could aid efforts to limit a building’s environmental impact. One of the biggest potential advantages BIM could provide to environmentally conscious designers is the ability to predict energy performance quickly and accurately, without the need for complicated calculations. Instead, the modelling software, itself, will be able to provide this information, and quickly recalculate the effects alternative strategies could have on overall efficiency. BIM also can help reduce construction-related waste, as they enable extremely accurate purchasing decisions—eliminating the need for just-in-case material ordering. Future BIM software could enable even greater energy savings by enabling easier interactive feedback on design-decision consequences. For example, lighting designers could quickly see the effect an added skylight might have on resulting lumen levels and architects could optimize the angle of exterior louvers to minimize heat gain without sacrificing natural light.
