Water main work to begin soon in Plattsmouth.
Nine bids were received for the work to install the main that will run alongside and go under the Burlington Northern Santa Fe railroad tracks in Plattsmouth
The Cassgram reports the main, one of two supplying water from the water treatment plant to the Plattsmouth city water towers, broke early in 2011. The city put everything in motion to get the main replaced last spring but high groundwater in the Missouri River basin prevented the work from starting.
With only one line serving the city and the flood of 2011 threatening the city water supply, the city installed an emergency backfeed system last year with the cooperation of Cass County Rural Water District #1 and the Beaver Lake Association.
The water main replacement contract had been awarded a year ago, but the work was rebid a few weeks ago because there were some changes in the design. Among them, engineers determined that only a 12-inch main was needed—as opposed to the 14-inch main planned last year—since the emergency backfeed now exists.
V & V Construction, Inc. dba Vincentini Plumbing, the low base bidder at $117,752, will do the work.
Vincentini was also the low bidder on two alternate bids for thicker piping. On the advice of the engineer and the public works director the city council authorized the expenditure of an additional $3,711 for thicker pipe which could add another 10% to 15% to the expected life of the main. “I’m all for taking the burden off people 60 years from now” who will be facing the same decisions, said Councilman Pat Dugan.
The city is bearing the cost of the project on its own; no federal funding is foreseen.
Councilman Terry D. Tilson was the only councilman to vote against the motion. As he did at the last meeting, Tilson said he was relaying public concerns about cost overruns. If this project comes back to council because a change order is needed, “people are going to scream,” said Tilson.
“We design upon the best information we can obtain at the time,” said Steve Perry of Olmsted and Perry Consulting Engineers Inc.
The project is to begin April 1st with a finish date of May 1st.
