Topping Slabs over Prestressed Members

ASCC Position Statement #38

ASCC concrete contractors recommend that the estimated camber at time of erection, calculated per the PCI Design Handbook or the PCI Manual for the Design of Hollow Core Slabs, be included in the Structural Notes. If the contract documents don’t specify construction in accordance with either Fig. 1(a) or (b), ASCC concrete contractors will bid the project based on a stipulated uniform thickness topping. Modifications requested after the bid award will result in a change order.

ASCC concrete contractors will meet the specification requirements for cast-in-place topping slabs over prestressed members; however, the engineer and
architect must consider the consequences of camber in the design process. 

If you have any questions, contact your ASCC concrete contractor or the ASCC Technical Hotline at (800) 331-0668.
