4. SFOBB East Span Seismic Safety Project 9:00 Welcome 9:05 Opening Remarks 9:15 Where we are now 9:30 Business Enterprise Outreach 9:45-10:30 Technical Issues/Changes since May 13, 2002 1030-1045 Break 10:45-1:00 Open discussion with contractors regarding above mentioned issues

5. SFOBB East Span Seismic Safety Project Who are we? SFOBB Project Manager Heavy Civil Construction Contractors Fabricators, Suppliers

6. SFOBB East Span Seismic Safety Project Why are we here? meeting is mechanism to inform the contracting community of the upcoming SAS Superstructure and In Bay foundation contracts. meeting is a way to create a dialogue with contractors, especially on issues of concern. for example we heard at May 13, 2002 workshop, mobilization payment for an "over the water" job does allow an acceptable cash flow for primes. We effected a change to the Public Contract Code for jobs of $25 million over water

7. SFOBB East Span Seismic Safety Project Tools PowerPoint Meeting notes Handouts

8. SFOBB East Span Seismic Safety Project Ground Rules no decisions to be made discussion only to take place speakers keep to their time dialogue to follow decorum in order to create an atmosphere of respect
