The ASCE Manual of Practice 145 is a robust analytical approach for “close-fit” flexible liner design. Built on the French National Practice ASTEE 3R (2014), is considerably more complex and accurate than design approaches like Appendix X1 of ASTM F1216 for circular host pipe and the WRc SRM Type II design method for non-circular pipe, both of which have been used in North America for many decades.
With increased accuracy, however, can come increased complexity and ASCE MOP 145’s robust nature truly has many moving parts that present unique challenges to both the Designer and to the Contractor to fully understand design intent and risks associated with that in the Construction Phase. This Webinar provides an overview of the MOP from both a Designer and Contractor’s perspective in terms of practical considerations for its use; how and how not to articulate design intent clearly as well as how to mitigate and distribute risk fairly and appropriately in the construction phase. The presenters use true case studies of its use in projects across North America in the past 3 years since the MOP’s introduction to the North American market.
