7 East Span Replacement (Self-Anchored Suspension bridge land foundation, W2) Unofficial Engineer Estimate: $29 million. This contract constructs the western most foundations and columns of the self-anchored suspension bridge at Pier W2 not far from the existing pier E1 on Yerba Buena Island. The work consists of two large excavations in the Yerba Buena rock for the footings, all necessary retaining structures, placement of the structural foundations in the W2 foundation excavations, and construction of the columns up to the bottom of the pier’s cap beam. The steel-framed anchorages within the footings are included in this work, but the cables running between the footings and the superstructure are excluded. Column reinforcing steel will extend above this level, typical of any column pour. (Self-Anchored Suspension bridge marine foundations, T1 and E2) This contract constructs the tower foundation at piers T1 and the eastern most foundations and columns of the self-anchored suspension bridge at Pier E2. The work is in and on the waters of the Bay just to the east of Yerba Buena Island and to the north of the existing bridge. The work will construct pile foundations (called “footings” on the plans) at both piers. The contract will also construct Pier E2 columns. The Pier E2 column concrete will extend up to the bottom of the pier cross beam. Column reinforcing steel at pier E2 will extend above this level, typical of any column pour. This contract will also include the anchor bolts, rods and associated miscellaneous work at Pier T1.
