The U.S. General Services Administration (GSA) and the National Aeronautics and Space Administration (NASA) are partnering to deliver a new Engineering and Mission Operations (EMO) Facility at NASA’s Ames Research Center in Northern California.
The new 30,292 square-foot facility, known as Building N278, will bring together key mission-support functions in a modern, efficient workplace with offices, private meeting areas, technical laboratories and support spaces. The project will help advance NASA Ames’ long-term vision for a healthier, safer, more flexible, and sustainable environment while reducing operations and maintenance costs.
Located near the intersection of Warner Road and Mark Avenue, the project also includes site preparation through the demolition of two existing structures, Buildings N51 and N216, and an adjacent fuel station. Once complete, the EMO Facility will provide a safe, flexible, and sustainable environment to support NASA’s engineering and mission operations needs.
Address: Moffett Federal Airfield, 1158 Cody Rd, Mountain View, CA 94043
Estimated Construction Timeline: Summer 2027 to Fall 2029
Estimated Project Cost: $40 to $60 million
Primary tenants: Moffett Federal Airfield and NASA Ames Research Park host tenants from defense, tech, academia, and federal agencies.
In February 2026, NASA contacted GSA to relaunch the EMO project. GSA formed a project team and began work quickly. Between February and June 2026, the team completed several important steps, including selecting AECOM to provide pre-construction support during the design-build phase.
GSA has also completed key early procurement steps, including a Sources Sought notice and an Industry Day event that generated strong interest in the project among attendees from across the industry.
The next major step is to release the Phase 1 Solicitation, which is planned for August 2026.
In compliance with NEPA, NASA determined that a Categorical Exclusion (CATEX) checklist is the appropriate level of review for the proposed action. This checklist demonstrates that no extraordinary circumstances exist that requires an Environmental Assessment or Environmental Impact Statement.

Traveler reimbursement is based on the location of the work activities and not the accommodations, unless lodging is not available at the work activity, then the agency may authorize the rate where lodging is obtained.
Unless otherwise specified, the per diem locality is defined as "all locations within, or entirely surrounded by, the corporate limits of the key city, including independent entities located within those boundaries."
Per diem localities with county definitions shall include"all locations within, or entirely surrounded by, the corporate limits of the key city as well as the boundaries of the listed counties, including independent entities located within the boundaries of the key city and the listed counties (unless otherwise listed separately)."
When a military installation or Government - related facility(whether or not specifically named) is located partially within more than one city or county boundary, the applicable per diem rate for the entire installation or facility is the higher of the rates which apply to the cities and / or counties, even though part(s) of such activities may be located outside the defined per diem locality.
