Abstract

A precast concrete step unit formed of left and right sidewalls, risers, and treads, wherein left and right sidewalls are assembled from a plurality of pre-cast sidewall panel modules, with a stepped panel module with two or more steps. Pre-cast concrete riser modules and tread modules extend between the right and left sidewalls. Reinforcing cross brace members are fastened to the inside distal surfaces of the left and right sidewalls where they are bolted into screw anchors embedded into the sidewalls. There are also screw anchor inserts embedded into the proximal ends of the sidewalls and into the ends of a first or lowest of the risers, and adapted for affixing the riser and sidewalls using clip angles or right-angle brackets. After alignment, the treads and remaining risers are installed using a construction adhesive which may be applied using a caulk gun. The precast modules each weight about 200 pounds or less, with none exceeding 250 pounds, and most much less. The installation can be carried out by an installation team of two workmen. One-piece concrete footing pieces can be used to support the lower edges of the sidewall panel modules.
