PROBLEM TO BE SOLVED: To provide a method and a facility for placing concrete capable of preventing a material from being separated when placed from an elevated place, sufficiently compacting the concrete since workers are arranged at placing positions, improving working efficiency since the work load for moving a hose for placing is reduced, and securing safe working environment. SOLUTION: A concrete is force-fed from a concrete pump vehicle 7 on a ground through a concrete pipe 8 to a concrete distribution device 6 installed on a placing stage 5 secured to a scaffold. The concrete is further fed from the concrete distribution device 6 to a vertical chute 9 disposed from a plurality of positions on the placing stage downward for placing it at predetermined positions.
