fred clark. let me talk about etfe because it was also raised at the last presentation. we looked very hard at e tfe. it's a wonderful material, a plastic material. if you remember the swim cube at the beijing olympics, that was etfe, the soccer stadium in munich, very well publicized building. it's a great material. the issue is that in our experience it does not age very well. it tends to get dull and tends to get rather used quickly. so it was a material we discarded but we did look at it at some length. the issue of birds and maintenance, of course is an issue with glass as well. we have an extensive program by use of certain materials and the structure itself to ward off birds. that part of the wall though frankly is still being looked at and the aluminum scheme is still being looked at. we have to report to you at some detail. aluminum is not wrong, it does tend to pit and corrode if the surface is not treated adequately at the time of manufacture, also that might be the case to paint the aluminum rather than leaving it exposed that's e

my name is fred clark. i'm a senior design principle architect for the transit center. we want today to bring you into discussion and development of the exterior wall of the building changing from glass to exterior wall. it's a change. the critical issues even though these are dramatically different materials, the critical issues that they still have certain aspects in common. one is that since the days of the competition we've always envisioned the transit center, even those it a very light building, it touches the ground very lightly and we felt the glass did that and metal does that equally well. the other thing that is very important that this is going to be the centerpiece of an entirely new neighborhood in san francisco. it has to be a great neighbor, it has to be a welcoming civilized humane presence and a building you want to live in and the wall does it equally. will : what you are seeing today, even though there are a number of the options, all of them will be what you will see today which has no discernable or dangerous scheduling impact on the work at hand.

when fred is given direction, fred clark, to incorporate the design guidance criteria that is embedded by everyone, he's taken to pencil to paper and looking at these numbers hard. the instruction he has from us is estimates to see if we can further refine them and bring them down. on the issue of the documents that are put together by dhs and fema and from a what i understand, the documents that are put together were at least post 9-1-1 and people who do build major structures, they are not put together by lay people. so, with respect to the geography, i can't speak to that because that's not my level of expertise. i have to depend on all the experts t warriors reason and 49ers stadium are going through a very extensive security system. they don't need to bring it out to the public like we do, but they are, like oklahoma and kansas city, they are. with respect to the safety act designation, the way it works, director, is once we have the design guidance criteria and approved by the board of directors, the next step is we then meet with them again in more detail, we put together and ap
