Madison's commissioners approved changes to plans for the updating of utility lines underneath Washington Ave. when they met on Tuesday.

The change order for Washington Ave. work contained two sections. The first dealt with installing new 4-inch foster adapters, pipe bends and gate valves with boxes at the appropriate locations. The second section focused on replacing old sanitary-sewer lines and old manhole structures at the N. 1st St. intersection.

As part of the 2019 project to reconstruct Washington Ave. through Madison -- a state Department of Transportation project -- city officials decided to install new water and sanitary-sewer lines underneath the street.

Chad Comes, city engineer, said that the first section would change the size of the utility lines. The total cost for installing the 4-inch equipment amounted to about $9,900.

To replace the old clay sewer line and brick-lined manholes, workers need to remove the old equipment, install 15- and 18-inch PVC sewer pipes, 18-inch sewer pipe bends, new manholes, and new manhole frames and lids. The cost for that amounted to about $26,000.

Comes recommended approval of the entire change order. Commissioner Mike Waldner supported approval, providing his opinion that it was a good decision to "...get rid of the brick manholes."

The total cost outlined within the change order amounted to about $35,890. The increase brings Madison's cost for the improvement project to $1.3 million. SDDOT officials calculate that the Washington Ave. reconstruction project, which is a section of SD-34, will cost about $7.9 million.
