Sir Ronald A. Fisher • Fisher was opposed to conclusion that smoking caused 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.” • Source: http://en.wikipedia.org/wiki/R.A._Fisher
NBIMS Interactive Capability Maturity Model (NBIMS I-CMM) USAF and USACE BIM Initiatives DoD-wide construction productivity benchmarking Overview
[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.

Project Overview • Kit of Parts – Structural • Assumes load bearing exterior masonry • Assumes concrete structure with maximum 30’ spans Unit A Unit B Support Unit C Commons Stair
Project Overview • Test Configurations
Army Transformation • Army Transformation • MILCON Transformation • Centers of Standardization • USACE BIM Implementation
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
USACE • United States Army Corps of Engineers • Program Summary: Evaluated in CCGs • FY10: $34.8 Billion
USACE • MP6: Amber, 91% • Cost Growth • MP7: Red, 76% • Project Time Growth • MP8: Red, 76% • BOD Time Growth • MP9: Red, 41% • Timeline (Duration) Growth • MP10: Red, 27% • Financial Closeout Average Score: 62% Note: Taken from CCG Report for all on-going projects as of 13 APR 09 for all Program years
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 OUTSIDE- OUTSIDE+ INSIDE
Summary • NBIMS Interactive Capability Maturity Model (NBIMS I-CMM) • USACE and USAF BIM Initiatives • DoD-wide construction productivity benchmarking
