costs are enhancements or redundancy to the base electrical system for the building, the base glazing system for the building and the structural system for the building. what is the protection for glazing system? what is that? >> so, the glazing systems, the glass, throughout the building. >> oh,. >> as mr. ducebella mentioned, there is... >> actually we have a slide on that or i could go through that in detail if you like. >> if you just give it to me. >> it is about making sure that the glass does not participate in becoming a hazard to people inside or around the transit center in the event of something occurs. >> and so, >> when you build many things with kind of resistant glass to start with, >> yeah. you start off with a basic tempered glass system. but this is layers lamination in the glass to make it safer and more secure. >> as you go through each piece could you give us a dollar amount? it would be helpful? >> i will have that when i speak to the distribution. >> all right, thank you. >> what i will try to do is be as explainable because there is this technology mystery because i c

as well as the glazing system package which includes not only the w 1 system but the specialty sky lights, glass floors and other systems in the package. we had originally issued that package for -- bid and suspended that process for the an allowing of the design of the w 1 system and we'll be actually folding in the remainder of the storefront glazing to increase the overall glazing component of the package, but to resume the bidding schedule on that, we need to issue an addendum in june of this year to keep that process on schedule as part of the overall construction package and that's where we are seeking guidance on this change. the opportunity to reduce cost in the glazing package is a significant one. when we have completed the bidding of the first 5 major packages which include the skavgs, substructure, super structure, glazing and ceilings, we have locked in about 2 thirds of the value of the construction center. within those early packages, this system because of it's area, because of it's magnitude, presents a present unique opportunity for to us reduce construction cost in a si

these are our enhancements as i discussed earlier to the glazing system. the biggest impact here, is on the awning system around the building which had been injured to survive a seismic event, but in doing additional analysis and in fact, some actual physical blast testing, some significant recommendations as would effect the design and performance of that system, and as i will mention a little bit later on, based on that information in part and the budget picture as a whole we are tasking the design team with taking another look at the design of the awning system. >> structural performance, there were a few locations where there was some minor enhancement recommended. this is indicated on the start as 0 percent, there are in fact, some costs less than half a million dollars worth of costs where there is some structural enhancement to the transit center. again, an area where we conducted exhaustive additional analysis on blast performance, but one over all where the seismic performance of the transit center, the robustness of the structure because of the ro

glazing and looks irresdescent and like munich and what is that appearance? >> the building will be approximately 50% glass where the areas of visitors will be. much of the arena at the highest systems and mechanical structures are not glass and some type of metal and we're still evaluating that and there will be a fair amount of glass so you have direct view to the area and the exterior of the building. it's not meant to be -- and some people are saying birds will fly in and we are aware of those issues and we don't want to create glare also and that is on going as the project continues. >> and is illumiation? >> we are aware of the beauty it provides and with the amazing light sculpture that is there. it's spectacular and getting world interest and the first thing is meet sustainability guidelines and make sure you don't have light leaks out and we don't want excess light on the pier itself and only for safety. >> is it similar -- i mean is there -- i know we have talked about seeing an actual -- >> model. >> have you created a model? >> i showed tonight various renderings and someone said they hadn't seen them and they were published in the newspapers. the model is being built no
