What typically happens when a novice starts down the ski slope without taking skiing lessons? I have seen what can happen and it isn't pretty. In like manner, if one begins the journey towards LEED certification without a map of instructions, the path will undoubtedly be arduous and will likely lead to somewhere other than the LEED plaque -- the Holy Grail of green building certifications. (Every LEED-certified building is given an official plaque listing the building's level of certification.)
The American Concrete Institute (ACI) announced the formation of a new technical committee on building information modeling (BIM) of concrete structures.
BIM allows project designers to create a digital model that represents a building or structure to ensure proper interface among building systems and materials before construction begins. ACI believes BIM's main advantage lies is that the digital model is "data-rich and intelligent, not merely lines representing
