Photographer & Submitter: Arash Parham
Parham snapped this image of workers from Bethesda, Md.-based Clark Foundation Group LLC installing a rock bolt into a tunnel wall on a $232-million project to build an automated people mover at Dulles International Airport in Virginia. As project manager, Parham often takes his camera along to shoot construction progress. This time, he says, it was teamwork that caught his eye. "I like this because it shows the effort that goes into this kind of work," he says.
