The floor system3 described in this publication is the result of an attempt to obtain a floor of masonry materials, at a minimum cost in placing, which will successfully meet the loading requirements placed upon it.
Most systems of masonry floor require considerable unproductive labor and materials which add to the cost but which do not contribute to the effectiveness of the ultimate structure. Forms must be built and dismantled. Even. where moveable and reusable forms are employed, the cost of assembling, dissembling and moving add to the charges which must be ultimately placed against the cost of the floor. This overhead becomes proportionally larger if the forms do not find continuous use.
