director kim: welcome to the transbay joint powers authority board directors meeting. my name is jane kim. i will be chairman today's meeting. please call roll call. >> director sartipi has a prior commitment and will not be present. [roll call] you do have a quorum. director kim: thank you. please call item 3. >> communications -- there are none to that i know

of. director kim: item four. >> director of new and old business. director kim: you can move on to item by if. >> good morning. we continue our coordination with stakeholders involving the transit agencies, east bay peninsula, city and county of san francisco, state, and federal agencies. with respect to our construction documents, early below rid of construction documents were received on the member for, on target to issue the bid for the early below great package around february 2012. 100% contraction documents for the transit center, 95%, 96% cds will be issued in the spring. we have moved a bit date to january 2012 to allow the design team to complete further testing. with respect to the bus storage, we are making good progress with

caltrans. we are ready to issue an rfp for construction management services some time at the beginning of next year. we held an outreach meeting this tuesday which lasted two hours, well attended. we had over 50 people there. the rail extension, we continue to work closely with a high- speed rail authority on the construction documents, the low- grade components of the document as well as the extension. in addition, i wanted to announce on december 2 we will be hosting an archaeological exhibit at our building at 201 mission pear that will run from december 2 through january 2012. we will be showing the artifacts that we uncovered from the transbay site. there will be artifacts, including industrial tools, household items, and remnants from the 19th century. it should be interesting for students and those interested in

a san francisco's early history. we are more than happy to rotate the exhibit. we could have it at mtc, the east bay, and other places surrounding the bay area. i also wanted to mention the san francisco unified school district has graciously invited us to their december 8 ribbon cutting from 1:00 until 2:30 at john o'connell high school. we will be present at that unveiling. congratulations. that is huge. we appreciate the invitation. the address is 2355 folsom st.. finally, more good news. the transit authority was awarded a $1.24 million grant from the federal transit administration so that we can complete some environmental work for the rail component of the private that we needed to do as a condition of our receipt of

the $400 million grant. now i would like to ask steve to give our construction updates. >> good morning, directors. construction management oversight. this month, lots of good progress occurred. you will notice the presentation is different. i took out all of those bullet points about the utility'ies. the reason for that is most of the utility work is complete. we are repaving the streets. there is one package to do, the obsolete water system on mission street. that is scheduled for the first quarter of 2012. the remaining packages are pretty much done. the time line that it before you on the screen, we are still tracking that. pre-trenching is fairly well along. completed this past week a final section on natoma.

cdsm, we will show you pictures of that as well. the west end of the project, everything west of first street is completely surrounded by shoring wall, at this point. zone 3, about two-thirds of the way down with the cdsm there. we will have all the shoring wall complete by the end of the week with the exception of street crossings, which rely on utility relocations. director ortiz: could you refresh my memory on the cdsm. >> cement deep shoring wall. we use that to create the perimeter around the project. zone 4. we continue to buttress work. that has made good progress. we are just over 2.5 shafts per

week, which is the goal to get to to complete our work on project. this week, having to report we will complete three full shafts. on the screen now you can see we have completed the sea dsm -- cdsm on the west end of the project. we mobilized to the south side and will complete that were before the end of the month. east end of the project from freemont through beale street has been completed. all that will be left on the shore wall will be the street crossings after the next phase of utility. to give you an idea between the sides, the photo on the left is the end of september, on the right, the end of october. that is where the buttress work continues. it is hard to see a lot of

change there but we have been very successful with the buttress work. the rest of the site, you can see how the area, their rigs that do the cdsm work, shore mall, have moved around. particularly, notice the large area of steel is getting smaller and smaller as we go to october. those beams code to the shourd wall. them minyas street operation was complete. the fence line will be moved just to the outside of the steel beams you see sticking up that represent the edge of the shoring wall. ministry will be reopened for the remainder of the project. i think it actually happened last week. there is a shoring wall at the law west and -- the west end.

we crossed fremont street the weekend before last, earlier in the month of october, completed across first-rate. these crossings are halfway across which allows us to move utilities one more time back over into the zone that the shoring wall has been completed in. then during the remainder half of the street. the infrastructure of the work has already begun on first street. here is a progress update on the buttresses being completed. the green ones are completed and poured out. the two yellow ones will be completed tomorrow, with the one on the left side being poured story to it tomorrow morning -- starting tomorrow morning. the rig has been moved up into the green wrote, we called it m1, which we will start drilling this morning that hole. here are some shots of the

buttress operation. you have seen this before. this last month we install the first reinforced buttressed shaft at location c1. we had some good luck with that. the contractor estimated it would take 20 hours to lower the continuous regard cage. only took about 10 hours. it looks like it will be easier than they hadn't originally envisioned it. some of the utility work finished up, restoration of the roads, and the start of face to infrastructure utilities on first street. we have given this were to balfour beatty and their subcontractors, reimbursed by pg&e to get the infrastructure in. and pg&e will come in at the end of the year and pull all the cabling and make the cut-over is allowing us to complete the shoring wall on the other side of the street. just a summary on the local labor, out of the 129 kraft

hours completed by webcor's team, 87,000 have been completed by local labor. if there are any questions -- director kim: comments or questions? director reiskin? director reiskin: thank you. ghraib report. it looks a tremendous progress that you all are making. -- great report. while it is clear the progress is significant, just looking at the graphics of the status of the wall, but dress, it looks like you might be running ahead of schedule. it would be helpful in these presentations to get a better sense of not just how much progress we are making, but where we are relative to the baseline original, and baseline cost. just glancing at the summary, it looks like you are going to beat

the shoring wall and buttress. >> that is based on the original baseline schedule. more than one month ahead in completing that area. unfortunately, that is not worth the critical path runs through the project. that is through the buttress that at this point. a thing that we can do to expedite that. but it is getting close to right where we expected it to be. there had been some issues with deeper holes. the rock is a bit deeper than originally anticipated, which often happens when you're doing a kind of work. but they are stepping up to the plate, so to speak, in getting the ball rolling. we are getting close to our projected 2.5 per week, which would keep us on schedule. director reiskin: and not all of them are reinforced? >> no, just along the shoring wall, and each of the vertical columns of schatz gets reinforcement -- shafts get

reinforced at the end. wherever the road ends, the last one is reinforced. >> we have asked last time to get a break out of the san francisco cfraft hours. perhaps trade by trade? >> we can provide that. director kim: thank you. >> now i would like to ask kevin clench to do the presentation on the bus ramps connecting the transbay transit center to the bay bridge. we have been working closely with caltrans. we have also presented and worked with planning and the redevelopment agencies and their staffs. >> good morning, directors. i am the product manager for the project. we are the segued to steve's

presentation. we are the product engineers for the deal-technical work. there is some overlap with wednesday was doing. i am here to present the update for the bus ramp design. i will go into some of the more specific aspects of the ramp. then i will talk on -- touch on the lighting and size the criteria. i am sure most of you are familiar with but the bus routes are, what they connect, but to show those who have not, the trend a terminal is on the left. the bay bridge is off to the right. the bus ramp is intended to connect those two as well as the bus storage facility, which is unfortunately off of the image. at this point, we are halfway through the design, approaching the 65% milestone which will be presented sometime early next year. focusing on the cable space --

cable structure, which is the closest part of the structure at the transit terminal. a couple of renderings to show you. this is the first year this is from second street down to howard, to the east. the one thing i wanted to put on the slide, in the diagram to the left, the train box extend well beyond the face of the building where the bus ramps enter the facility. rather than putting a foundation through the train box, which would involve some different structural interactions, we chose to put the support for the tower away from the train box, which led to a long stand. we considered a number of different options and decided that the cable stay solution was the most effective. that is how we have arrived where we have. the second image, the same cable

stay. this is more at eye level. moving on to the viaduct section, the area that covers folsom st.. looking at a typical cross- section, his will be essentially your standard caltrans box girder seen throughout california. we have had a number of planning and redevelopment to go over this to make sure they are comfortable with the profile. i should also add we are providing services for the streetscape project what we are

proposing now is a much lighter , partly due to construct- ability concerns, in order to construct the viaduct and put in the falsework and leave enough room below it for vehicles to pass we have come up with and gently shaped arch. it gets thicker toward the middle. looking over at the harrison street crossings, which are more to the east, the projects south, clothes into the bay bridge. the image is the caltrans fremont's off ramp, which was --

we plan to reflect the same lines profiles to more or less have the same type of bridge, so when it is done, it will look consistent. again, we ever do that with planning and they agree with the philosophy. looking at the lighting for the roadway, there are essentially two types. for the majority of the bus ramps, we will use post top lighting, which is what everyone is familiar with. off to the right, where we have the cable stake, the roadway is more narrow. we do not want the post lighting to interfere with the cable stay. and there, we are putting in whiting as a barrier to shine in on the roadway. looking at it in detail, the light fixtures will be embedded

in the barrier, pretty well concealed, and then shined down on the roadway. here we have a wider roadway, this is a crude diagram, but ms. lee -- mostly to show the with. -- width. for the cable stay itself, we're in the process of developing renderings to come up with a lighting scheme. to give you a preview of our intent, our philosophy behind it, we looked at the cable stay beneath the two roadways. we can put a soft glow on the cables to give the structure presence in the neighborhood without necessarily overpowering its neighbors. likewise, the same lighting can be projected down onto the public space below to make it a safe environment. once again, to point out some overlap, our lighting designers

are also involved in the streetscape project. we will look at the lighting from below and above to make sure they are working together well. the last item on the agenda is the seismic design criteria. just some main bullet points. we have reviewed this with the seismic review committee, which consists of many people respected in their field. seismic criteria has been established to create a common level of such performance between the bus ramps and the trade itself. lastly, we have compared and worked on developing a performance criteria for the boss track which is similar to that being used for the sky way, which is currently under construction. if there are any questions on all of that. >> thank you, directors.
