PROJECT QUESTION: S-60 (2574) Soil Preparation requires soil amendments installed in two separate 6 inch lifts. This does not appear to be a cost effective way to install the amendments and it would add to the risk of damage to the existing roadway, utilities and trees. Can this requirement be removed from the specifications?

Response: Language in this section was modified in Addendum 1. ‘…….Soil amendments shall be thoroughly blended and incorporated into the existing soils to a depth of 12 inches.’
