Is there a leaner way to construct? This question was asked by Howard S. Wright, a construction company, project team members Chris Martindale, Jordan Cash, John Hansen and Brian Lemmon.
The goal: To find cost and time savings.
The project: Husky Stadium, the outdoor football stadium on the campus of the University of Washington in Seattle.
The team used lean construction principles throughout the project to help eliminate waste and non-value adding components during the building phase. One of the main goals was to find another solution to the structural plan, which initially called for metal-framed bracing to tie the interior walls to the structure above.
“…we were able to design self-supporting structural walls that do not need additional support or bracing from the building’s structure,’ said Martindale, project executive for Howard S. Wright.
This process not only simplified clash detection, allowing for the MEP components to run freely without obstruction from the lower wall braces, it also saved the project thousands of dollars and countless hours of labor.
Other solutions accomplished by the team included the installation of shared supports for acoustical ceiling tile and MEP systems. This also reduced the number of attachments made to the structure, increasing productivity and reducing costs.
Overall, the use of these lean methodologies produced a number of results that were beneficial to the team as well as the client. ‘We are constantly striving to provide greater value to our clients by leveraging lean processes, which made this lean event outcome particularly rewarding,’ Martindale said.
Additional lean methodologies were used that helped the job become a ‘model project’ that demonstrates the newest in construction technology. For example, the entire team used laser scanners for data points and layout, as well as building information modeling, SmartBoxes, and iPads to increase efficiency and productivity.
