Design includes pre-cast lid with opening for manhole riser stack. Design loading: HS20 truck load plus applicable gravity and lateral soil loads. Design is for an installation in Kentucky. Project is structural design of precast water quality boxes for a precast drainage products manufacturer (Sherman-Dixie Concrete
Indus -tries).The purpose is to obtain general approval for structural design for SDCI-supplied precast water quality boxes for a community in the state of Ohio. Four separate precast box sizes were evaluated and designed ranging from 36"X96" to 96"X192" in plan view. Design included provisions for HS20 wheel loads for shallow installation depths. The boxes were evaluated for the maximum permissible burial depths as well. The manufacturer plans to start supplying these water quality boxes as soon as agency approvals are complete.
