Project overview: The site has a double-layer layout on the ground and underground, the basement level is 3.6 meters high, and the ground level is 3.0 meters high. The ground floor is a brick-concrete structure, and the ground floor is a light steel portal frame structure. The site is 44.74 meters long and 23.98 meters wide. The building area is 2,143.52 meters, of which the basement floor is 967.76 square meters and the ground floor is 1175.76 square meters. Divide the underground training area and the above-ground inspection guidance area, and construct simulated houses, simulated blocks, simulated residential buildings, and auxiliary facilities.
