Abstract: A precast concrete beam element, used as a continuous bearing structural foundation member supporting wall and floor slab loads in soil, includes a bearing surface for spreading vertical loads into the soil and a wall section having a height sufficient to place the bearing surface at a specified bearing depth in the soil. The precast beam element also includes a formed-in notch to serve as a block ledge to facilitate weathertight wall installation. The beam element is manufactured offsite in a mold capable of changing dimension to cast elements with differing bearing heights and differing wall thicknesses as soil and loading conditions require.
