Rough electrical work is underway and Bob discusses the challenges of wiring an old building, particularly in New York City where there are strict code requirements. The electrician, Eddie Fisher, uses metal-shielded cable to reduce the possibility of damaging power lines, both during installation and over the building's lifespan. Insulation is also going on. Bob joins George Saylor from Owens Corning to learn more about the type of insulation being used in the apartments. Taking a break from the action at the project building, Bob tours the Brooklyn Navy Yard, the country's oldest dry dock. Now converted for a variety of functions, the Navy Yard houses everything from television and film production studios to commuter boat docks.
