MEASURED APPROACH MODEL DEVELOPMENT STANDARDS & REQ’S Standards vs. Requirements Good, Bad & Ugly Owner Requirements “If there is no campus standard and guideline in use, comply with the recommendations and guidelines of the United States National CAD Standard and the National BIM Standards, as currently amended.” a.Physical data b.Material characteristics c.Scheduled equipment product data as amended by installed product data d.Construction specifications “The Good, the Bad and the Ugly” United Artists, 1966

MEASURED APPROACH MODEL DEVELOPMENT STANDARDS & REQ’S Response? The Disclaimer This model looks great so you can look at it but you can’t use it for anything or rely on it for anything which includes, but is not limited to, everything. If you use it for anything anyway then you have to pay my lawyers anything they want if I get sued for anything related to your use of the model for anything. Have a nice day.

MEASURED APPROACH MODEL DEVELOPMENT STANDARDS & REQ’S Response? Disclaimer approach: Some of it’s not reliable so don’t rely on any of it. Specified-Use Approach: Some of it’s not reliable so only rely on what I say you can

MEASURED APPROACH MODEL DEVELOPMENT STANDARDS & REQ’S LOD Definitions 100Estimate it. 200Specify it. 300Buy it. 400Build/Install it. 500Operate it. DETAIL = Input* DEVELOPMENT = Reliability * Usually more Input than Reliability

MEASURED APPROACH MODEL DEVELOPMENT STANDARDS & REQ’S Use of LOD's No correspondence with design phase No such thing as an “LOD ### model”

MEASURED APPROACH MODEL DEVELOPMENT STANDARDS & REQ’S Use of LOD's Use LODs with a model disclaimer? Authorized Uses? (in AIA E202) – Within Integrated Project Delivery – Traditional delivery methods

MEASURED APPROACH MODEL DEVELOPMENT STANDARDS & REQ’S Conclusion Planning versus plans Don’t just “do BIM” Measure successful objectives Get involved with open standards Plans are worthless. Planning is essential. - Dwight D. Eisenhower
