Abstract: In recent decades within the building industry, there has been a trend toward mass production of building components. The trend has included every part of structures except for the concrete slab the building is built on. The “Threshold Tray and Clip System” uses mass-produced products to be applied to construction of slabs and foundations, allowing sill steps to be built in rough openings with pre-fabricated form parts. The forms remain in the concrete and are permanent. This means that consistent results can be expected. Other mass-produced products, such as door systems, will fit into rough openings more accurately. Over-all quality of the structure will be increased.
