Excavation and Embankment
203.1DESCRIPTION
1 This section describes the requirements for excavation, hauling, disposal, placing, shaping,
grading, compaction of material; and installing and maintaining settlement platforms. 2 Excavation classifications are as follows:
1.
Borrow Special Excavation is a pit-run, granular material taken from specified material sources.
2.
Muck Excavation consists of the removal and disposal of saturated soils or saturated mixtures of soils and organic matter from within the construction limits but not associated with culvert installations. Soils or mixtures of soils will be classified as muck excavation only if they cannot be excavated using the same equipment and procedure as used for unclassified excavation. Classification and removal of unsuitable materials associated with culvert installations is specified in Section 206, Excavation and Backfill for Culverts.
3.
Rock Excavation consists of the removal and disposal of igneous, metamorphic, or sedimentary rock, which cannot be excavated without blasting or the use of conventional excavating equipment. The limits of rock excavation are based on seismic velocities as defined in the contract and the structural characteristics of the bedrock. Excavation outside these limits is unclassified excavation as defined below.
4.
Unclassified Excavation consists of the excavation and placement or disposal of materials encountered in the work, including excavation from material sources, not classified under other contract pay items.
