Chicano Park Mural Restoration Project
Chicano Park is a 7.9 acre park located beneath the San Diego-Coronado Bridge in Barrio Logan, a predominantly Mexican American and Mexican-immigrant community in central San Diego, California.
The park is home to the country's largest collection of outdoor murals (67), as well as various sculptures, earthworks, and an architectural piece dedicated to the cultural heritage of the community. Ghirardelli Associates was chosen to oversee the first restoration of 18 of these murals since they were first painted in the early 70's.
WETA, Oyster Point Ferry Terminal Update
The dry-docking (DD) operation took several hours. The sequence involved moving the dry-dock away from the pier and slipping in a spare barge between the dry-dock and the pier. They sunk the dry-dock so that the floor of the dock was about 6" deeper than the steel barge. They then floated the steel barge onto the dry-dock and raised the DD until it was just touching the bottom of the steel barge at which point the steel barge was flooded to neutral buoyancy. Next, they slowly sunk the entire thing until the concrete float was sitting about 6" deeper than it was expected to float.
Once this was complete, they blasted air under the concrete float and it lifted free. free of the barge, the concrete float was towed away (back to Richmond) while the shipyard began the long slow process of raising, dewatering the cleaning up the steel barge.
