so what you're looking at is a rendering of the idea. basically this linear water feature running pretty much the whole length of the park on the roof with a nozzle of spring water located every four feet in the taping patterns. and then -- you guys have seen lots of these rendings of the buildings. but basically the buses drive through on a layer below the park. and the idea is that in the ceiling of the passageway where the buses drive through, that will would be these ultra sonic censors that would detect the passage of the bus and render that movement in water. and so just some of my thematic drawings. and basically, this will be a very simple fountain. a lot of modern fountains have

elaborate computer control systems where you can choreograph the movement of water. in this fountain, there's no computer. it's a wonderfully simple system. there's just an ultra sonic censor, and these are the technology that was developed for detecting water level in big shipping vessels and water tanks and fluid tanks. it's basically a beam of ultra sound that bounces off a liquid level and senses the height of the liquid. and there's wonderful robust indestructible technology. these things are designed to put in some tanks where you never have to go get them and do anything to them again. so the idea is that in this ceiling, there's one of these censors every four feet, and as the buses drive through, when the beam gets interrupted by a bus, it opens the and -- opens the valve and lets water flow. so every censor is linked to the

nozzle directly above it. i think there's 256 of these nozzles and censor arrays. that image there shows what the actual thing looks like. they'll be set into the corgations in the ceiling. a little hard to see, but kind of a cross section showing how the water will come up out of a grading system. it will be recycled water systems. so the water will reveal the passage of the bus. it's a very water and energy-efficient pattern. just some other renderings of other water features with similar nozzles, and then kind of the concept image of revealing the passage of these buses.

so questions? back over to jill? >> thank you very much, ned. >> lastly, i'm very pleased to announce the director of cultural affairs, a member of the steering committee, who would like to say a few words about the art program. >> thank you, board members, for this opportunity to address you. since i arrived in san francisco 2 1/2 years ago, i've had the pleasure of being associateed with many very exciting art events and installations here in san francisco. everything from the the two mya lynn sculptures instilled at the academy of science, to the chung wong that we have installed at the civic center.

my association with the transbay project for me feels like one of the highlights. because you are bringing online to the city a building that will be iconic, that will be a landmark for generations to coming and it has just been such a pleasure to work with the architectural team of pelley clark pelley, and their vision for this phenomenal facility. and the way we have been able to select these fabulous artists to identify works that complement the building. when you see how it excos with the concept of a park and the garden that is on the roof of the billing. when you look at ned kahn's interactive water fountain

display and the way that it in realtime reflects the movement that is taking place underneath that garden and highlights and manifests that movement symbolically for the visitors, you see how the architecture and the art really are working together. so it has just been, i think -- i'm urging you to approve. this although the san francisco arts commission doesn't have any jurisdiction over this project. we did, however, present all of the artists and their concepts to them. they wholeheartedly endorsed this plan and the selection of the artists. it's really great to see san francisco-based artists and internationally renowned artists like jenny holster and james carpenter and tim hawkinson all being part of this enormous fabulous project. thank you very much. >> thank you, luis. i'd like to, on behalf of the tkpa thank all the artists for your time here today and your presentations. it's all very much in line with

what we're trying to achieve, which is a very light, open, welcoming, joyful jewel for the city and county of san francisco for many generations to come. and you all in different and wonderful ways contribute to that goal that we have set for the program. thank you very much. >> motion to approve the design complex for the four recommended artist? >> second. >> it's been properly moved and second. let's call the roll. >> [roll call] >> five ayes. item 14 is approved. >> next item. >> authorizing the executive director for an amount not to exceed $44,000 with the downtown parking operator to provide 28 indoor parking spaces per day

for cal tran's legal office and to maintain such an agreement so much as the total amount is not exceed budget in a total fiscal year. >> deborah keith will report on this item. >> good morning, directors. deborah keith, outside counsel. the cooperative agreement between the state, the city, and the tjpa provides a reserve to the state, 28 parking spaces in the new transit center for legal counsel. the new transit center does not have a parking garage. in the alternative, the cooperative agreement provides that the tjpa will provide 28 parking spaces within a certain distance of the new transit center. this item would authorize the executive director to meet the terms of the cooperative agreement in a line item budgeted each fiscal year for the amount not to exceed that. >> it's been moved. >> seconded. >> seconded. >> no no members of the public have wished they wish to direct

you. [roll call] >> item 14 is approved. >> item number 15 is authorizing an amendment to the next item. construction manager general contractor services for the construction of the transbay building and related structures with the joint venture of web core to increase the time for construction services to 110,000,800 hours. >> bob will -- 110,800 hours. >> bob will report on this item. >> thank you. when we awarded the contract to web core own -- obiya shvings i, our initial plans for to move into construction into the fall

of 2009. we are now going to be moving into construction here in august of 2010. over this last year, web core has worked have been closely with the tjpa and with the design team evaluating the constructability providing input on the cost estimate, construction schedule, and value engineering efforts. the number of b that we will be preparing and the time period over which we will be preparing those bid packages has also extended out. so this contract modification is to increase the number of hours to reflect the additional effort from web core obiyashi over the past year, and through the bidding of the construction packages. if you have any questions, i'll be happy to take them. director cohen: what's the budget impact of the change?

>> it's roughly -- i'm sorry. let me do the math real quickly. it's about $6 million of additional fees and that fits within our overall budget for construction services. director cohen: it's well within the contingency planned in the original contract award? >> question. in our program budget. the original contract award was for the base 45,000 hours plus the 7.8% mark-up on the value. it's within our budget contingency. >> you said 45,000. you meant 45 million? >> 45,000 hours. >> oh, ok.
