Lean, Innovative and Unique Project Solutions

The team used steel instead of two-by-fours as templates for one and one-and-a-half-inch anchor bolts to gain efficiency. Using steel prevented swelling when the templates became wet, and made the templates easier to remove from the anchor bolts during finishing. The team also found the steel templates were easier to drill and adjust and could be reused more times that the two-by-fours.
