Pankaj Saharia is an experienced structural engineer who makes his home in Shrewsbury, Massachusetts. Since earning his Masters degree in civil engineering from the University of Detroit in 1992, he has been involved in numerous engineering projects, including the design of bridges throughout Massachusetts.
His bridge designs range from pedestrian bridges for railroad bridges. He was the structural engineer who performed the structural design of the superstructure and substructure of the Bradford Railroad Bridge in Westerly, Rhode Island. “I carried out bridge geometry calculations including top of form elevations, bridge seat elevations over [the] abutment, [and] drafted engineering drawings in AudoCAD.” His work was done under the supervision of a senior professional engineer.
There are a number of differences between the designs of highway bridges and railroad bridges. The most obvious difference is that railroad bridges must bear a tremendous amount of weight, far more than do highway bridges. Since the majority of railroad routes in the United States are well-established, most new railroad bridges are built on existing routes. For railroad bridges, a design known as a simple span structure is preferred. In bridge design, crucial factors are constructability and maintainability. This is because interruptions to service are considered much more critical to railroads than they are for highway agencies.
Pankaj Saharia of Shrewsbury has been a member of the American Society of Civil Engineers for more than twenty-five years. He is also a member of the United States Green Building Council, which sets standards for environmentally friendly building construction.
