The quantities shown are “neat” counts, contingency values should be added for construction
estimates.
The soil parameters used for this preliminary quantity estimate were assumed. Actual on-site
conditions may differ from the assumed conditions and may cause the estimated quantities to
change.
This preliminary quantity estimates for GravityStone Edge and is meant to assist the contractor in
preparation of a bid package. It does not include additional materials that may or may not be
required to construct the wall(s) including but not limited to waste, filter fabric, drain tile or other
materials to address drop structures and other obstructions in the reinforced zone. It is the
responsibility of the contractor to verify these quantities provided through their own estimate. Race
Engineering Assoc., LLC accepts no responsibility or any discrepancies between quantities provided
in this estimate and quantities required by the final approved design.
