Collage Construction


How do you meet an ultra-aggressive (some might say impossible) schedule for a complex and highly sophisticated laboratory building? Use Lean Construction, a scheduling approach that maximizes efficiency and minimizes waste, and integrate it with Building Information Modeling to maximize the opportunities for offsite prefabrication. This innovative approach is how Sundt saved the Arizona Board of Regents millions of dollars on the Interdisciplinary Science and Technology Building 4 (ISTB4) project at Arizona State University in Tempe.


Prefabrication returned $2 million to the owner and shaved 16 weeks of construction time from the schedule. By using this innovative approach the team was able to prefabricate:


• 100 percent of the ductwork
• 30 percent of the plumbing
• 90 percent of the fire protection
• Five percent of the electrical


The building’s north and west façades were prefabricated off-site, as well as nearly all of the building’s laboratory components with its electrical, process piping and teledata interfaces.


Sometimes the impossible becomes possible when existing technologies are combined into one innovation.
