APP Jet Center has broken ground on a major expansion and renovation of its San Francisco-area location at Hayward Executive Airport. Slated for completion by year-end, the $5 million project will see the construction of an additional 20,000-sq-ft hangar capable of sheltering the latest big business jets, along with a new 3,000-sq-ft passenger terminal. It will also include renovation of the facility’s existing 12,000-sq-ft hangar and office space to which the new structure will be attached. “Hangar space is in high demand at Hayward,” said Thom Harrow, CEO of parent company APP Properties. “We look forward to meeting that demand with this development and offering the best service and facilities to our clients.”
