777X spar assembly finds its home in retrofitted Everett site building

The first 777X spar load in building expected later this summer

Workers install a mega truss on the rooftop of the 40-02 building in Everett, Wash., last year — one of two installed over the low bay end of the building.

When finished, the repurposed building will be an important facility in manufacturing Boeing’s newest jetliner, which is still in development. Work continues on the facility to prepare it for the first spar load there later this year.

Spars help give the wing its structure and are typically the first part of an airplane to be assembled. A right-side wing will be built for practice thus summer for the first static airplane.

Built in the early 1990s, the 215,000-square-foot facility most recently housed the Electrical Systems Responsibility Center, among other uses. With the Everett site’s main factory already at capacity, “the 40-02 building provides needed manufacturing and office space” for 777X spar assembly, said Kirsten Hoover, Shared Services Group (SSG) project manager.

Boeing is working with contractors from Jacobs Engineering, Hoffman Construction and Degenkolb Engineers on the retrofitted building. The 777X team began meeting in 2015 to determine what alterations would be needed to handle the 777X program’s manufacturing processes.

“Over time, as their manufacturing processes matured, their building requirements were clarified,” Hoover said. “We needed to stay very flexible to ensure the design and construction activities were aligned with the production requirements.”

To date, Boeing has invested more than $1 billion in the 777X Composite Wing Center, which now neighbors this repurposed building.
