work done by the contractor in 1989 and the fact that the City uses St. Paul water, which is softer and contains less sediment than traditional well water. The interior dry coating has held up well and is still original from when the tower was built. There was some spot repair in 1989 but it remains is good shape. There is lead present in the paint on the interior dry surface so extra precautions will have to be used to properly remove and contain that paint that is removed. Qualified contractors are well - trained in the removal of lead paint. The miscellaneous repairs include a new mesh screen at the end of the overflow pipe, a new hatch for the 30" riser pipe, the installation of cable -type fall prevention devices on the staggered ladders, reinstallation of a loose tie rod under the bowl in the dry interior, replacement of burned out light bulbs, installation of a new frost -free vent, and the installation of LED aviation lights on the roof. All of these repairs coupled with the new paint should put the tower in a good position for the next 15 -20 years. The City of Roseville will also be refurbishing a water tower in 2014 so the two cities have been working on this together since they will potentially need to rely on each other for water while the respective towers are out of service. Only one tower will be worked on at a time. Staff thought that combining the two towers could gain some economies of scale but multiple firms have said that the pricing would be the same since the equipment has to be moved and rigged either way, even if it is only a few miles. Roseville and Little Canada had conversations with both of the firms discussed below. Some were joint meetings and some were separate, but both cities have shared information throughout the process. There are many different ways to complete this type of work for a water tower. There is traditional design - bid -build where a consulting engineering firm prepares plans and specifications, advertises for bids, and then awards the contract to the lowest responsive and responsible bidder. There is design -build where a consulting engineering firm partners with a designated contractor to complete the work and avoid the bidding process. State statute allows for this model to he used on water tanks even though the price exceeds $100,000. And there is a lifetime contract opportunity where the City pays an annual fee and a contractor takes over all maintenance of the tower for the rest of its life. All of these options have pros and cons and after checking with other cities and performing additional research staff decided that the design -build option makes the most sense for the City's water tower. SEH Engineering is located in Vadnais Heights, MN and has been performing design - build projects for over 8 years. In that time SEH and Classic Protective Coatings (Menominee, WI) have partnered to complete numerous tanks. They know what they are doing and Classic is very highly regarded for their work on water towers. The design - build option also includes additional work during the five or ten -year contract. The tank is inspected annually and any necessary spot repairs are completed at that time. The tank is pressure washed in year five and year ten if it is a ten -year contract. All work performed by SEH and Classic is under warranty for the duration of the contract, which 2
