OVERVIEW OF PENNSYLVANIA'S GENERIC DESIGN AND CONSTRUCTION SPECIFICATIONS FOR PREFABRICATED WALLS

The introduction of proprietary walls in the early 1970s has necessitated the development of generic specifications to encourage competition. The Pennsylvania Department of Transportation (PennDOT) has developed such specifications to combine the mechanically stabilized earth wall with the modular wall. This combination creates a prefabricated wall. This paper gives an overview of the policy and procedure, design, and construction requirements for prefabricated walls. PennDOT uses prefabricated walls as an alternative to conventional reinforced-concrete walls. The discussion covers applicability of these walls to specific site and loading conditions, limitations, tolerances, factors of safety, dimensional limitations, design parameters, drainage, and life requiremetns. The special design and loading considerations are also presented.
