Pier 70 in San Francisco, California, is a historic pier in San Francisco's Potrero Point neighborhood, home to the Union Iron Works and later to Bethlehem Shipbuilding. It was one of the largest industrial sites in San Francisco during the two World Wars. Today, it is regarded as the best preserved 19th century industrial complex west of the Mississippi.
The pier is 65 acres (0.26 km2) in size.
The area around Pier 70 has been used for shipbuilding since the Gold Rush. Since becoming home to the Union Iron Works in 1883, Pier 70 has been occupied by a variety of industrial concerns, including the Pacific Rolling Mills, Risdon Iron & Locomotive, Kneass Boat Works, Union Iron Works, Bethlehem Shipbuilding, and BAE Systems.
After Bethlehem acquired Union Iron Works in 1905, the pier also housed Bethlehem Shipbuilding Corporation's administrative offices in Building 101.
Bethlehem Steel sold their holdings in the area to the Port of SF in 1980.
As of Jan 3, 2017, the facility is operated by Puglia Engineering, Inc, who operate 2 other ship repair facilities in Washington State. Puglia Engineering purchased the facility from BAE Systems Ship Repair in January, 2017. The two dry docks were formerly operated by BAE Systems San Francisco Ship Repair, employing approximately 200 people.
