as we move forward, the feasibility study was adopted in 2007 to begin the eir eis. one thing i should note that is different about geary, the prop k line which specifies it must be rail-ready. we are doing more on the design work to make sure that if the decision is made to enhance rail, the physical dimensions are incorporated so we can minimize potential impact. one of the first items i should know in terms of new scope, we identified three alternative contract amendments. the contract identified only two build alternatives. similar to van ness, we are looking at three build alternatives in addition to the baseline. we have many different technical studies under way for the project. as part of the study, one thing we have identified are a couple of new areas of work that need to be focused on, moving forward. part of the design drawings, they pay focus to that, and a majority of the pending studies are contingent on the completion of the design drawings. as soon as they are complete, we expect them next year to move forward with additional studies. one of the key
