Sir Ronald A. Fisher
Fisher was opposed to conclusion that smoking causedcaused lung cancer.
He compared the correlations to a correlation between the import of apples and the rise of divorce in order to show that “correlation does not imply causation.”

[A] Building Information Model[ing] (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition. A basic premise of BIM is collaboration by
different stakeholders at different phases of the life cycle of a facility to insert, extract, update or modify information in the BIM to support and reflect the roles of that stakeholder.

Attachment F
Strengths: Promotes BIM use on projects Spells out minimum modeling requirements Platform Neutral for non-COS Projects Promotes Competition Tied to Army BIM Road Map, COBIE, etc.
Challenges: Nebulous “Implementation Plan” Min end product required still = just drawings Without interoperability portfolio-wide, sharing will remain
difficult BIM in FM limited

Benchmarking Approach
Compare Projects to Similar Facilities by CAT CODE
Apply the Central Limit Theorem to Summarize/Characterize Traditional Projects
Establish 90% or 95% Confidence Intervals
