PGSuper is a well-known design program that was originally developed by the Washington State DOT (WSDOT). It is now being used for some other DOTs as well. The person at WSDOT who is responsible for maintaining the program is closely involved with the development of changes for the LRFD specifications, so has first-hand information on how to implement any changes to the programs when changes in the specifications are made. We recommend you speak with a PCI-certified precast producer regarding their experience with PGSuper and other design software.
