Photos from 1830 Rittenhouse. It was early in the morning, and I was just testing my camera levels when I happened to capture the right moment when a helicopter flew by and the project manager was looking down towards me from the mast climber. C & C construction has been replacing the external balconies down in the heart of Philadelphia. This historic building is the first high rise ever to be built in Rittenhouse. Here are a few photos of the mast climber in operation.
