Commercial Curb Third Lane Expansion, Canopies, and Solar Photovoltaic System

JMT designed two new 250 ft long canopy structures to provide weather protection for disembarking passengers at a new commercial curb lane at Washington Dulles International Airport. As part of the design, JMT provided field topographic surveys, utility designating and locating, civil engineering design of a new raised curb median and sidewalk, structural engineering, and detailing of custom canopies that were intended to match the existing canopies on the adjacent curb.

JMT also performed the electrical engineering for the project, which included the design of new LED lighting and one photovoltaic (PV) system for each canopy structure. Each PV system consisted of 4 kW solar panels connected to a 10 kW maximum inverter. The PV system tied directly into the airport’s 480/277V electrical distribution system. The system complied with the rapid shutdown requirement of NEC 2017. Any excess power developed by the PV panels was returned to the airport’s electrical power distribution system instead of local battery storage.
