The PCEF Bulb T beam was developed by the FHWA Prestressed Concrete Committee for Economical Fabrication.  The beam was developed to be a structurally equivalent substitution to the New England Bulb T (NEBT).  NPP fabricates the PCEF beam (as it was developed by the FHWA), the PennDOT modified PA BT, and the NYSDOT modified Deck Bulb T.
