The Contractor shall confirm all earthwork quantities
prior to start of construction. If an excess or
shortage of earth is encountered, the Contractor shall
confirm with the Owner and Engineer the requirements
for stockpiling, removal or importing of earth.
Minor adjustments to the grades may be required to
earthwork balances when minor excess material or
shortages are encountered. It is recognized by the
parties hereto that the calculations of the Engineer
in determining earthwork quantities shall be ac-
complished in accordance with the American Society of
Civil Engineers Standards for such calculations.
Further, that these calculations are subject to the
interpretations of soil borings as the physical limits

and that all of these parameters may cause either an
excess or shortage of actual earthwork materials to
complete the project. If such an actual minor excess or
shortage of materials occurs, the contractor shall
contact the engineer to determine if adjustment can be
made to correct the imbalance of earth.
