B.

Rock excavation: Removal of boulders having a volume of 2 cubic yards or more, solid bedrock and ledge rock that cannot be excavated or removed by dozers with rippers, but require systematic drilling and blasting or the use of pneumatic rock splitters, hammers, and wedges. If material that is classified as rock is mechanically removed with grading equipment, the volume of material removed shall be measured and paid for as common excavation.

C.

Common excavation: Removal of all material not classified as rock excavation.

D.

Over-excavation: Removal of suitable material below the limits designated for excavation.

E.

Site Structures: Footings, foundations, slabs, pavements or other features constructed above or below ground surfaces.

F.

Unauthorized Excavation: Removal of materials beyond indicated sub-grade elevations or dimensions without direction or approval by the Project Manager.

G.

Disposal Material: Excavated material beyond the quantities required for the Project or unusable for the Project. This includes materials that are unsuitable for fill, in excess of fill quantities required, and/or contaminated.

H.

Fill (embankment): Material placed immediately on top of existing ground or excavation.

I.

Sub-grade: Uppermost surface of an excavation or embankment.

J.

Sub-base: Material placed immediately on top of the sub-grade only under the following conditions:

1.

In all areas where unstable sub-grade is present.

2.

In all areas where structural fill has been placed.

3.

In all areas where fill material is required as shown on the Plans.

K.

Base Material: Material placed immediately on top of the sub-grade or sub-base and immediately beneath the finish surface (i.e. pavement, concrete).

L.

Leveling Course: Uppermost surface of the aggregate base, usually 2" thick, used to eliminate irregularities in the contour of the aggregate base surface prior to placing asphaltic concrete.

1.03

Disposal material shall be hauled off site and completely removed from the Owner's property. Disposal of contaminated soil shall be in accordance with federal, state, and local laws and regulations.

F.

Contractor shall conduct excavation Work in such a manner as required to protect existing trees and vegetation on site.

G.
