Abstract: A system for moving building materials, such as brick, stone, tile and similar items, at a work site including one or more mover dollies and one or more hand carts. The mover dollies generally comprise an elevated platform on which the building materials are positioned and wheels or other similar mechanisms by which the mover dolly may be repositioned at a work site. Building materials are loaded on the mover dolly and a hand cart is used to locate the mover dolly at the work site where skilled masons may remove the building materials in connection with building a structure. As building progresses, the mover dolly may be repositioned without unloading the building materials. When the supply of building materials on the mover dolly is depleted, the mover dolly is reloaded and returned to the work site using the hand cart.
