Dumbarton Bridge Seismic Retrofit

Our role in the Dumbarton Bridge seismic upgrade was cutting the pier into six sections each weighing 85 tons, using diamond wire technology and experienced technicians. When those cut pieces were removed, our Brokk 330 robotic hammers were deployed to break up the 240 cubic yard footer encasing 52 wooden piles.
