Pittsburgh Efficiency.

This is the structure that will be the surface entrance to the Gateway Center Station of the Pittsburgh Light Rail System. Since March, this structure has existed as you see below.

For three months, welders on cranes have been welding these metal pieces together in the morning, then grinding the welds in the afternoon. Then repeat the same process in the same location the next day.

In the old country, in three months, you can hire a crew, built some molds, tie down rebar, and pour concrete. And still have time left to watch it dry!

This structure is just steel pipes.

No wonder the North Shore Connector Project is behind schedule and over-budget.
