Engineers journey to the bottom of a dredge well at Pier 38. At this point in construction, the dredge well was roughly 75 feet (23m) deep. |

March 2003 – Blue concrete forms and steel reinforcement bar mark the beginning of the upper caisson. |
|
|
Pier 37: Open dredge wells on the lower caisson will be capped with round concrete covers. When the caisson has reached its founding (final) elevation the caps will be temporarily removed and a 30-foot (9m) layer of concrete will be placed (poured) to seal the bottom. |
|
|
Pier 37: Concrete caps cover the dredge wells. The cap in the distance is being hoisted into place by crane. |
|
|
The upper caisson begins to take shape on Pier 37. Part of the wider lower caisson is still visible above the water line, and concrete is being placed on the fourth level (lift). Each lift is 10 feet (3m) high. |
|
|
Pier 37: The upper caisson grows taller. Concrete work is now on the sixth lift, as shown in this photo from the web cam. |
