The construction industry is poised to enter into an era of high performance and production by merging Lean Construction practices with comprehensive wholebuilding and systems measurement. W. Edwards Deming urged, “Train people to measure things and they will keep pushing their own standards to beat themselves.” To even have standards there must be a basis by which they are measured against. Comprehensive measurement systems must be instituted in order for the Lean Construction vision to be fully realized. To achieve this, sophisticated computing science applications are called for. This paper presents a vision for whole-building measurement integration into the different phases of Lean Project Delivery. A program-based BIM (Building Information Modeling) 3 system is developed to provide such a measurement application. This program-based BIM provides for the early planning and programing stages, what the geometric-based BIM systems provide for design. More than that, it provides total life-cycle cost simulation. With the adoption of standards from which to measure against, the construction industry will experience a re-training of the mind, as Deming proved in other industries. This re-training begins with top-down whole-building measurement in combination with bottom-up component and sub-system measurement. The computing science and modeling technology now exists and soon ready for market. The next need is data: both for baseline (business as usual) actual whole-building results, as well as benchmark (improvement) cause and effect claims.
