( CNN ) -- 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 . Atypical to most Corps of Engineers contracts , the contractor hired will be required to supply mezuzahs , which it describes as parchment inscribed with Torah verses , `` for each door or opening exclusive of toilets or shower rooms . '' Generally , mezuzahs are placed in a case and attached to a door frame as a sign of the Jewish faith . The construction site , on an established Israeli Air Force base , will be guarded by `` an Israeli citizen who served in the IAF '' and will be separated from military installations with a solid 6-foot fence . Despite the precautions taken around the base , construction workers will be subject to stringent security regulations . Non-Israeli employees are required to arrive on and exit from the site `` in a group only '' ; `` the fenced area shall have one gate only for both entering and exiting the site '' ; and during work hours , employees are prohibited from leaving the base . The notice also states that the employment of non-Israeli citizens is forbidden , except those from `` the U.S. , Canada , Western Europe countries , Poland , Moldavia , Thailand , Philippines , Venezuela , Romania and China . '' It specifies that the employment of Palestinians is strictly prohibited . In addition , it says , `` the Contracting Officer retains all rights to refuse or inhibit employment of any employee . '' Site 911 appears to be one of the largest facilities built by the U.S. Army Corps of Engineers , which maintains three offices in Israel and has been credited with building a variety of facilities for the Israel Defense Forces over the last few years , including underground hangars for Israeli fighter-bombers and command centers . The purpose of Site 911 remains unclear . The Israeli Embassy in Washington and the Israel Defense Forces did not respond to requests from CNN for comment .
