Boeing, the world’s largest aerospace company and leading manufacturer of commercial jetliners and defense, space and security systems, selected McCarthy to provide multi-phase, design-build work for its 10-acre Composite Center of Excellence manufacturing and painting center project in St. Louis.
The project includes a 367,000-square-foot high bay steel frame building addition that included material receiving/shipping, storage, material layup, autoclaves, trim/drill core carving and overhead cranes for Composite Material Fabrication of Boeing’s commercial 777X aircraft parts. The construction of a 57,000-square-foot paint facility was added to the project as well. Castle Contracting provided mass excavation, grading, and wet utility installation for this project.
The building serves as the production hub for manufacturing composite parts to fabricate wing and empennage pieces for Boeing’s new 777X airplane program
Well-executed self-perform capabilities played a large role in this job for both the design and construction phases. More than 4,500 tons of structural steel, 4,000 cubic yards of building foundations and 3,000 cubic yards of concrete for equipment foundations were showcased in the execution and performance of this project.
With somewhat intimidating scheduling constraints, the design-build delivery allowed construction, design and client teams to fully collaborate, helping them determine critical paths and prioritize requirements from all parties early in the process. Quality efforts early in the project expedited the start-up and commissioning process, allowing the team to achieve mechanical completion ahead of schedule and deliver the overall project five days ahead of schedule despite one of the wettest summers in recent St. Louis history.
There is a 115,000-square foot, drywall-enclosed layup space with a 30-foot vertically clear, hard ceiling that meets clean room standards. The 3,600-ton central utility plant manages the HVAC system and also included in the project are load center unit substations, site stormwater retention and detention basis and a parking area.
Because of limited accessibility on the north end of the jobsite, two separate drill rig companies were hired to keep the project moving.
Expected to generate leading technology in the aerospace industry, the Boeing 777x aircraft will be housed in the Composite Center of Excellence. With unique folding-wing technology and capability, the aircraft are able to be stored and maneuvered unlike any previous aircraft.
The Boeing Composite Center of Excellence project was completed by MC Industrial, a wholly owned subsidiary of McCarthy Holdings, Inc.
