VALUE • “By By giving researchers access to our  giving researchers access to our experts and workers, we are receiving  site‐specific information, which we can  then share with our project managers then share with our project managers  to increase productivity”  • “It’s a win‐win situation for everyone  i involved. The university receives  l d Th i i i reliable data, participating companies  benefit from custom analysis, and  everyone across the industry learns  h d l valuable insights in a generic form.” j Bruce White, Project Director,  PCL Construction Management Inc. (CONSTRUCTOR, 2007)

“Calgary Construction  Association reported  over a million dollars over a million dollars  savings within a year in  the collaborated research  companies because of  p the direct impact of this  research .” Dave Smith (Executive  VP), Calgary  Construction  Association (Alberta Construction  Magazine, May/June  2006)  50
