City of Elk River <br />Jackson Street Water Tower Condition Assessment August 3, 2015 <br />CDG Project # 15010.00 <br />OBSERVATIONS I REFERENCE PHOTO <br />50. The cap atop the <br />roof appears to be <br />in average <br />condition. <br />DISCUSSION AND CONCLUSIONS <br />Introduction <br />This condition assessment focuses on two main points concerning the Jackson Street Water <br />Tower: the overall structural condition of the Tower, and the requirements to preserve the <br />Tower to maintain its integrity and value. Part of the preservation plan is to restore the water <br />tower to its original appearance, which will require extensive work to clean and remove old <br />paint, rust, and growing lichen. A few rusting areas, such as at connecting splice plates on <br />the outside of the legs and deteriorating areas within leg bases also present a concern from a <br />structural standpoint. <br />General Discussion <br />From a structural standpoint, all components of the Water Tower appear to be performing <br />well. Besides some more superficial issues, such as the presence of chipped paint, rust, and <br />lichen, all steel components are in average condition, especially for their age. The legs are <br />securely bolted to the concrete footings. There are no noticeable problems with any of the <br />tie rods, horizontal girders, or lattice work on the legs. <br />The Water Tower's legs consist of two steel channels sitting parallel to each other and riveted <br />to a long, flat steel plate on the edges on the outside perimeter of the Tower and small <br />is <br />COLLABORATIVE DesignGroup,,lw. <br />
