Pre-formed concrete section

Abstract

A pre-formed concrete section comprising a deck and first and second legs extending from the deck. The deck includes a first side, a second, and a width extending between the first and second sides. The deck also includes a top surface, a bottom surface, and a thickness extending between the top and bottom surfaces. The distance from the first leg to the second leg is more than two times greater than the distance from the first side to the first leg. The width of the deck is more than four times greater than the distance from the first side to the first leg. The thickness of the deck decreases as the deck extends outwardly from the first leg toward the first side. The thickness of the deck decreases as deck extends outwardly from the second leg toward the second side. A platform including multiple sections includes unevenly spaced legs.
