Abstract: A method of forming cast concrete modules made of a floor, two spaced apart upstanding walls, and a roof extending between the walls. The method uses casting beds in groups of four and one set of forms, two interior and two exterior forms, which are movable from bed to bed. By performing different steps of the method on different casting beds on different days, separate modules can be erected progressively on separate beds in a group of four, so that with one set of forms and one group of beds, three modules can be produced every eight consecutive days.

Abstract: Method and apparatus for pre-casting box-like reinforced concrete modules on assembly line. Apparatus includes pair of movable interior forms for defining the interior surfaces of side walls and ceilings whereby one interior mould at a time can be removed when concrete is in semi-cured condition. Method includes casting floor with short upstanding side wall portion to serve as guide for interior forms when moving forms onto floor slab. Method also includes use of integral multiples of four serially arranged casting beds on which various procedures for forming modules proceed simultaneously and progressively.
