The Boeing Company

Cash & Associates has provided Architect-Engineer Services for projects at Boeing facilities in Long Beach, Palmdale, Downey, Anaheim, and Huntington Beach, California.  Examples of project experience include:


BUILDING 150, NANA ORBITER HANGAR
USAF Plant 42, Palmdale, California

Prepared a comprehensive seismic strengthening/retrofit evaluation of an existing 120,000 square foot, single story, high bay structure used to house NASA Orbiter (Space Shuttle) maintenance and modification operations.  The study criteria involved preventing damage to the Orbiter and Orbiter-related equipment while maximizing personnel life-safety.  Deficiencies were identified relevant to potential to damage the Orbiter during a major seismic event along the San Andreas Fault.








BUILDING 004 SEISMIC SURVEY & RETROFIT
Downey, California

Preparation of a comprehensive structural/seismic survey and construction documents to retrofit/upgrade an existing 240,000 SF single story, steel frame structure with concrete walls and a poured gypsum roof.   The study objective was to identify modifications required to strengthen the structure to prevent loss of life during a Maximum Credible Earthquake.  Identified deficiencies included lack of capacity in the existing poured gypsum roof and lack of seismic anchorage/bracing for equipment and interior components.   Retrofit measures developed included installation of steel framing to reduce shear (seismic load) at boundaries.  In addition to seismic retrofit measures, construction documents included modifications to achieve building code compliance for such areas as building corridors, exiting, and ADA accessibility.  Although, the Downey plant was abandoned before the retrofit was undertaken, Cash & Associates provided follow-on assistance to various potential developers and the City of Downey.




VARIOUS FACILITY PROJECTS
Long Beach, California

Prior to closure of the majority of Boeing's Long Beach Plant, Cash & Associates provided Architect-Engineer Services for a variety of projects ranging from new construction to modification of existing facilities and miscellaneous site improvements at Boeing (formerly McDonnell Douglas).  Project examples include a new 12,500 square foot central plant (see Facilities - Central Plants); modifications to a structural test hangar to create a C-17 Aircraft Mission Control Sub-Subsystem Integration Laboratory; and structural engineering services to support various plant electrical upgrades. 




BOEING SPACE SYSTEMS
Huntington Beach, California

Architectural and structural engineering services for site preparations to facilitate installation of a new top loading vapor degreasing system within an existing building.  Project scope included demolition of an existing non-compliant degreasing system and development of area separation requirements.  To facilitate installation of new equipment, it was necessary to design modifications to existing walls and door openings.  In addition, a temporary visquened corridor was developed to avoid contaminating a nearby cleanroom during construction.  A new door, between the degreaser and pit, was provided for maintenance purposes.  All access ways and penetrations outside the degreasing room were required to preserve the integrity of the cleanroom by allowing positive room pressure.  Other elements of the project included relocation of existing mechanical and electrical systems, as well as a hydraulic reservoir.
