5. OLDIBUSINESS (Cont'd Ethafoam rope and caulk 3/8" wide x 1/2" deep with Sikaflex - la sealant (color: black), and seal terrazzo. Mr. Oesterling advised this solution has been reviewed by the design consultants and they believe it is a practical solution to the problem. They would caution, however, for a period of time there will be a dis- coloration difference. Their speciality is black terrazzo. They recommend that this be the method for improvement. Commissioner Wiggins informed Mr. Oesterling that he and Commissioner Cira walked the Plaza area and looked at the terrazzo area this morning prior to this meeting and suggested that some things have happened since he may have made his inspection. There are a number of cracks that appear to extend from the heaved areas out into the body of it that run from three, four, five feet away. This area seems to be pretty general all over the whole thing, and it would be our opinion that our consultants evaluate this. It looks, to us, that you need to remove the whole thing and do it all over. Now it has heaved along all of those joints; but in addition to heaving, this, in turn, has caused stresses that have put cracks into the terrazzo out into the body of it. There are some areas that seem to be spalling off. Mr. Oesterling said that is another problem -- another' separate problem. Commissioner Wiggins agreed that is another problem, "but I don't think thatis associated entirely with the joint situation. So, with all of the cracks that are now appearing, we go through a pre -thaw cycle, and I would be very apprehensive that the repairs that you suggest, even though they were done, that we wind up with the area adjacent the repairs coming apart, too. If we are going to have to fix it, let's fix it right -- one time! I believe in that old carpenter's adage- -you measure twice, saw once. It appears to be far more extensive than just the problem of putting half on either side of those joints." Mr. Oesterling said he agrees with what Commissioner Wiggins said and that they will take it under advisement. On the one sample they took, the edge was extremely tight and bonded well to that concrete. Commissioner Wiggins stated those cracks will admit water and they will come apart. Mr. Oesterling replied those are shrinkage cracks; on the terrazzo and pools, you will note that there are some hairline cracks. Commissioner Wiggins said these are more than hairline; these show up. Mr. Soltesz said he would like to raise a question here. "I am glad that the hairline cracks were mentioned on the pools, and, of course, we have had quite a bit of discussion on that also. Who is going to pay for this? Now, is that one of those 'guarantees' that is going to cost the City nothing and belongs to the contractor for the warranty that it is on ?" The Chair advised it is under the warranty agreement and Mr. Brownell verified that that is correct. Mr. Soltesz again asked, "It costs the City, or the Redevelopment Department, nothing ?" The Chair again responded, "That's right!"
