Louis Construction, Inc., in the amount of $64,994.50, to address the need for additional 10" PVC sanitary sewer pipe to make future expansion less disruptive and not as close to the proposed lift station, the addition of several manholes due to a condition in the field that was not discovered during design, and the option of using high early concrete pavement repair that would allow the pavement to be driven on sooner.
