This structural detail shows a concrete grade beam and floor slab transition incorporating a prefabricated trench or catch basin. The assembly features a checkered plate cover set at the top of the main floor elevation of 100.00. Grade beam reinforcement follows the schedule with 25M bars at 200 spacing top and bottom each way, and vertical and horizontal reinforcing including 15M bars at 200 spacing. A pour break is detailed with U-bars and slab reinforcement referenced to the structural plan. Trench dimensions indicate a 300 width with 250 depth and 300 by 550 footing dimensions.
