This Boeing project required moving equipment that weighed more than 28,000 pounds.


777X Systems Integration Labs

Location: Seattle

General contractor: Washington Patriot Construction

Owner/developer: The Boeing Co.

Primary designer: Harris Group

The $26 million-plus project included repurposing six separate lab areas throughout the 500,000-square-foot 2-122 Boeing Plant 2 building to serve the new testing program for the 777X aircraft program.

The project included moving a variety of new and existing equipment, many weighing over 28,000 pounds and requiring specific move plans, specialty cranes and lab-specific safety protocols. The project was time- and budget-driven to support the 777X development program, and demanded continual earned-value management, weekly critical-path schedule reviews and updates, and daily end-user meetings.

The uniqueness of the project required flexibility and the development of new construction techniques to install, sequence around, and develop strategies to complete a project for parts never developed prior to this project. Changes were common given the innovation and fast-paced aerospace industry. A collaborative design, construction and owner team made it a great success.

A 3-D building-information modeling program was used to develop the complex routing of the electrical cable tray systems, sweeps and drops to marry up with the welded compressed air piping, large-diameter high voltage conduits, structural steel, and many duct drops fed from the three large air-handling units.
