Lean, Innovative and Unique Project Solutions
Cianbro utilized multiple Lean solutions to make the project a success. Pull planning helped the team break down the project schedule and meet the six-week milestone activities. The team scheduled equipment deliveries directly to keep the site from being overly congested and stored owner-supplied equipment at three remote off-site facilities. The team also leveraged Trimble GPS technology for survey and layout on the job site. 
The team broke down punch lists by work packages and finalized the lists as packages were closed out. That way, there were no unknown punch list items to close at the end of the project.
