The U.S. Army Corps of Engineers is receiving bids to build a five-story complex for the Israeli Air Force, or IAF, near Tel Aviv.

The facility, mysteriously dubbed "site 911," will be built under the auspices of the Foreign Military Sales program and is expected to cost the U.S. between $25 million and $100 million, according to a solicitation for bids posted on a U.S. government website.

Only U.S. construction firms are able to bid on this contract, and the deadline for proposals is December 3, according to the notice. The notice, first reported on by The Washington Post, includes structural plans that show the first three underground floors are roughly 41,000 square feet and will include classrooms on Level 1, an auditorium on Level 3 and shock-resistant doors throughout.

The architectural plans, drawn up by prominent Israeli firm Ada Karmi-Melamede Architects, pays close attention to the aesthetics of the design as well as the functional parameters outlined in the solicitation. For example, three picnic tables are planned for the exterior.
