Per the adopted pavement design manual, clay soils with high plastic values are to be treated with lime. These soils were tested and found to need lime treatment. This change order adds the cost to treat the subgrade soils with lime.
Also found during the excavation, were conflicts with the proposed storm drainage and existing water line in several locations. Rather than replace the entire line, the change order reduces the scope of the replacement of the full water line and focuses only on the conflict locations.
