Optimizing New Build Constructability

This special session will present the ongoing works that are willing to optimize constructability by appropriately translating structural response into reinforcement needs.

This session will include presentations from industrial and academic experts to raise the heuristic of the constructability issues due to rebar congestions (from calculations to onsite preparation including execution drawings) and to raise the ongoing actions and potential ones to address these issues. This involves some presentations based on WEC’s AP1000 and EDF’s EPR recent feedbacks of design and construction.
