" Doug in Central Park we have a number of follies and structures that are original but this the Bethesda terrace and the part underneath it is the most imposing isn't it yes this is definitely the most significant structure we have in the -- I guess we'd call it romanesque and made up of -- made of sandstone and designed by October books with the principle architect and Jacob -- mould his assistant was really the one that designed all the carvings and the ornamentation. And then the carving was made in place right yes it was carved right in place in the park -- represent these pieces with the birds and stuff all the four seasons and walked down the staircase you have each season on each side of you so you have all four on the two sets now sandstone is pretty fragile how do you keep it in good shape -- unfortunately it Weathers horribly what we do was when it really Weathers to a point to really replace the sandstone carve out a section -- people dutchman. We put in new section and we carve it and it's our own staff in house that does that yeah we've we find that's the investment. Now that looks beautiful out there but we've just walked into the underneath of the terrace. And we're just looking at rob brick vaults what what went on here well what was here were 49 beautiful. Ornamental tiles missing files and -- files as we see overhead yes we put two back several years ago we did a prototype kind of -- re creation to see what it would take. To put all 49 back and we're very excited we're about to now is why were they falling -- whether what well in the early eighties we're doing a major restoration to this area and we were doing some exploration we found out that the backing on these tiles was rusting. In getting to a point where they had to be taken down so they weren't cemented up to the bricks they were held by metal it was a metal fastener right into the -- And so that at all rotted away and that's where -- and took him -- we packed them -- put him away and it's been about twenty years -- right -- what's it gonna -- to -- big project it's -- cost -- well over three million dollars -- what does that does that come out of the operating budget of the park no fortunately an individual who lived in -- that loved Central Park loved preservation put -- in -- will and when -- escalation Davis -- all the -- do this project to a civic minded little old lady in New York right -- most of -- money -- Central --"

" Bob I like to introduce you to the man in charge of this project this is Chris -- Chrysler's vice president for operations to meet you. What have you got down there. This is of the backside when he's now this is one of the backside of 49 panels. It's as you said before it's made out of wrought iron. And you could see this as a carried it Wentworth and mass failure on the big pieces have turned off this is one of the mechanical fasteners yeah. That holds one of the individual -- and each -- mechanical fasteners this arched shape then corresponded to the arch in the brick is the piece of cats which corresponds to the Burkhardt and this sat in the frame. Zones. That's on the ceiling up top so how many of these are up there. Are meant to be up there are 49 panels and what is the size of each panels served -- half feet by eight has seen. Anyway about the little over time -- big job. It is no small undertaking if that's at sixteen valve over 16000 tiles what's the deal with the one that's way in the back -- propped up against the walls that's actually an original panels is an extraordinary good shape you can see the contrast between one where there's been a mass failure and one where the system worked really well depending on where wasn't -- And the amount of moisture that it was -- but it's all about the water getting in the end up throwing water so that one shows the original. Pattern and the original tiles in their placement now what kind of tiles arteries these are written tiles from England. The company is still -- who might -- indeed so how do you go about recreating all of this. Well this is actually some of the tiles from the panel behind us that we were just looking and this is one of the corners where you can see. Definitely this is representative really of some of the deterioration where the rust and the iron has just continued to expand and caused a failure in the mechanical fastener."

" So the way they designed -- he had an actual little bronze clip that. Went into the backside of the tile and then there was there plaster in between the iron and there was this imitations. Cementitious layer which held them down so it was like a belt and suspenders system normal tile system you had to basically -- board -- and in mechanical fastener to hold the place and of course the bronze is fine just -- isn't fantastic shape this static. Essentially they cast a little -- eloquently in the filled with claims each one was ready to go with an accident. And our system will basically replicate that with modern materials what material will you use for the new framework the new framework will be all stainless steel. Okay -- stainless steel. And the key will be keeping the tiles in place and stripping it all bar stripping only iron off and putting the stainless steel without moving was trying to limit the amount of moving tiles really so it's not like you're dealing with -- thousands of tiles -- just dealing with 49. -- yeah the hallmark of the restoration at 49 panels not 16000 times you'd go crazy what what about some of these and a little something like this get. We used here. Well pretty damage that part of the design process is really determine. How much of the original fabric could we restore. And this is one where there's probably about 25 to 30% failure in the tile itself. And we like to keep as much as sort. So we work -- an in house staff. And a staff consultant and servers to conserve Republicans this and this is one of the tests conservation to determine if we can do it. Are -- not particularly happy with the glazing finish yet but we're definitely on the right track in terms does this pattern and this is the original and this is the Regina -- How much time as this -- It'll take about two years into the whole thing. Two years into the whole thing and get them back into place looking at 2500 fell 2500 pound panel up was no small wonder I think we all admire. Guys like you who can handle these undertakings just rested -- heard Justin off. We'll come back in 2006 that you've got a good thanks Doug thanks Chris."
