SEPTA Susquehanna-Dauphin Station Upgrades

This project included design and construction for the rehabilitation of the Susquehanna-Dauphin Station on the Broad Street Line. Station improvements included energy efficient lighting, wall, floor, and ceiling finishes, customer amenities, signage, passenger control and cashier facilities, platform tactile warning strips, an A/V public address system, and the installation of elevators. The results of this project, in concert with other proposed improvements, made the station ADA accessible.

Arora Engineers (Arora) provided mechanical, electrical, plumbing, fire alarm and fire suppression, and special systems engineering services for new, modified, and relocated systems. Design documents associated with the station upgrades included drawings and specifications from conceptual design through to construction documents and construction administration.


Mechanical: Energy-efficient designs for the heating, cooling, and exhaust equipment and distribution system.

Electrical: The upgrade to the electrical system included power distribution, receptacles, elevator power, and lighting.
