NRCS-4/13/2021 420-3

6. Items of Work and Construction Details The class of site preparation is based on quantities derived from preliminary survey data. Variations in these quantities may be possible when the work is actually performed. However, modification to the contract will not be made for work performed in excess of these estimated quantities except under the following conditions:

a. The variation must exceed 10% more than the maximum quantity established for the class of site preparation and have a minimum contract value for the additional work in excess of $1,000.00. (The contract value is to be determined by dividing the lump sum amount in the bid schedule by the applicable maximum yardage for the class of site preparation shown for the contract item in the table of quantities.) If the variation exceeds 10% and $1,000.00, the class of site preparation will be adjusted and paid for at the rate for the adjusted class.

b. It is the Contractor’s responsibility to submit proof that the estimated site preparation class in question exceeds the percentage and cost parameters in item (a) above. Proof will consist of applicable survey data or other measurements made by a qualified surveyor in accordance with recognized professional practice and the contract specifications.

c. The survey data or other measurements as applicable shall be presented to the NRCS prior to any work on the contract item for which the quantity is questioned. Three (3) working days shall be provided to the NRCS to verify data prior to the beginning of work for this contract item.

d. A final survey or other measurements as applicable shall be made and presented to the NRCS after the work is completed which will allow measurement for the quantity in question. If this survey data indicates justification for a contract modification within the parameters of item (a) above, it will be made in accordance with the changes clause contained in the contract.

Site Preparation shall include the removal of existing culverts, headwalls, concrete, and concrete riprap as shown on the drawings or marked in the field. Site preparation also includes any salvaging and placement of existing rock or concrete rubble as shown on the drawings or staked in the field. Site preparation includes the installation of county furnished culverts as shown on the drawings.
