With the completion of the Meadow Park Dam renovation, the Crossville City Council approved the final change order, closing out the project with a savings of $661,813.49 less than the original contract price.
According to city engineer Tim Begley, the project is complete and the other agencies involved have reviewed the project and given their approval of the work. The reduction in cost comes from the reduction in final quantities of material used, money back from the boat dock allowance, post tension anchor reductions and the redesign of the two buttresses that were previously approved by the council.
The original contract price was $4.482 million and the final cost was reduced to $3.615 million on the project that renovated and reinforced the almost 75-year-old dam that was built in 1938. The project included grouting leaks in the dam, including pumping grout into the rocks underneath the dam, as well as drilling through the dam and anchoring the dam into the bed rock. In addition, two buttresses have been added to the dam for additional support.
The potential still exists for the raising of the height of the Meadow Park dam at some point in the future that would allow an increase in the size of the reservoir to increase the local water supply. Currently, the city is working with the U.S. Army Corps of Engineers on planning for water demand and the environmental impact of such a project.
The Lake Tansi raw water supply project was also part of the Meadow Park dam improvement, but those costs are separate from the cost of the dam renovation. During certain times of the year, the city can draw overflow water from Lake Tansi to supplement the water in Meadow Park Lake.
In addition to approving the final change order, council approved adding back a few items that were removed from the original project, including bridges and railings across the spillways and the dam, along with fencing and a concrete ramp for handicapped access. According to City Manager Bruce Wyatt, the project will be bid with the ability to drop portions of the project if it runs over the amount budgeted.
Council members also approved the recommended bid on planned improvements at the wastewater treatment plant for the change over from chemical-based final water disinfection to a system that uses ultraviolet light. The bid for equipment and installation on the project is $608,500.
Veolia Water's Clark Annis explained that the new system was better environmentally and there are possible energy savings from the changeover. Annis added that the new equipment would be able to handle the plants peak flow for the next 15-20 years.
Annis told the council that the Tennessee Department of Environment and Conservation along with the national Park Service were please with the city's plans. The water from the plant empties into the Obed River that is classified as Tier III and one of the most protected waterways in the country.
Council members heard a report on the Crossville Memorial Airport fly-in held late last month. According to City Marketing Director Billy Loggins, the event gets bigger every year. He described this year as having a great turnout.
Councilman Boyd Wyatt described the airport as "one of the finest assets Crossville has." Wyatt said the traffic waiting to turn into the airport was backed up all the way to the Playhouse entrance during part of the day. Wyatt added that some 150 people took advantage of plane rides and helicopter rides that were offered to the public.
Crossville Mayor J.H. Graham III proclaimed October as domestic violence awareness month. Carmen Wyatt, director of Avalon Center accepted the proclamation from the Mayor and thanked the city and the Crossville police department for their work to assist victims.
