Changes to a water main project affect a community. The contract the City of Plattsmouth had with L.G. Roloff Construction to repair the water main in the BNSF railroad right-of-way has been terminated.
High groundwater tables in the Missouri River basin prevented the work from happening in 2011 even though the city put the project on the fast track 10 months ago. Now, with the successful test of the new emergency water back-feed system last week, the project scope has changed a little and the city is asking for bids on a new water main design.
About a year ago, the city discovered the 12-inch pipe running under the Burlington Northern Santa Fe railroads tracks was broken. The main is one of two feeding the city’s water towers.
Roloff was the winning bidder on the replacement work and it was hoped the project would be done in the spring.
With only one main operational and concerns about flooding at the city’s well field and water treatment plant, the city paid for an emergency back-feed system from the Cass County Rural Water District #1 and the Beaver Lake Association. The first full system test was last week and the system passed. (Cassgram 1/12/12)
The contract with Roloff last year was for a 14-inch replacement main, explained Steve Perry of Olmsted and Perry Engineering. With the dependable back-up system in place, the need drops back to a 12-inch main now, he said. There is also a slight routing realignment.
Perry said he talked with Roloff and the contract cancellation is “not an issue.” Roloff did ask that city agree to pay a restocking fee of $1700 for 14-inch valves Roloff purchased last year. The city council indicated it would have no problem paying the fee when the claim is submitted.
Bids on the revised plan are to be opened February 17th and the contract recommendation is expected to go before the city council on February 20th.
