As you are aware, per Century West's memo dated February 10, Tun <br />Terich has concluded that these cracks are the result of slab shrinkage and the downward pressure caused <br />by the stressing of the post tensioned deck. Century West has suggested that the owner's repair these <br />cracks either through epoxy injection or a carbon/epoxy wrap. Additionally, Tim has generally described <br />how Pence/Kelly could potentially reduce this cracking on firture pours. The owners appreciate Tim's <br />timely response to the problem. <br />Marion County and SAMT continue to remain concerned about the number and size of the observed cracks. <br />This concern is obviously heightened by fact that these cracks appear in critical column locations beneath <br />the busmall. With the anticipated bus loading and deflection we want to make absolutely certain the <br />structural integrity of the busmall has not been, and will not be, comproxnised. <br />At yesterday's consh-uction meeting you indicated that you will follow up with Tun to get a detailed written <br />description of his recommended modifications to the top of the columns in those areas that have not yet <br />been poured. Please forward a copy to P/K as soon as possible to prevent any delays or additional costs. <br />MMDC has advised, and the owners agree, that it would be prudent to employ the services of another <br />engineering firm to verify the most likely cause of the cracking at the top of the columns. It would be to <br />benefit of all those involved in project to confirm, with as much certainty as possible, that the cracks are <br />purely a cosmetic issue and not a shuctural issue. We would ask Arbuckle to contract and pay for these <br />services directly. If Arbuckle chooses not to obtain a second professional opinion, the owners do reserve <br />the right to hire the engineer directly and seek remuneration. <br />Thank you for your attention and consideration in this matter. Please feel free to contact me with any <br />questions or comments. <br />Since ~ y, <br />~ <br />Craig .
