    Revision of F2787 - 13(2018) Standard Practice for Structural Design of Thermoplastic Corrugated Wall Stormwater Collection Chambers

    (What is a Work Item?)

    Active Standard: F2787 - 13(2018)

    Rationale

    The current foundation bearing specification requires unreasonably high factor of safety, in some interpretations. This is inconsistently displayed in the non-mandatory appendix, which confuses users. In addition, the design mandates a single-layer approach for foundation soils that is not accurate or conservative in all cases. The text will be changed to incorporate a rational safety factor approach and to allow improved foundation bearing calculation methods.
