1.3 DEFINITIONS

A. Backfill is defined as fill immediately behind foundation elements or retaining walls.

B. Excavation: Removal of material encountered above subgrade elevations, and to lines and dimensions indicated, or as directed. Excavation may be classified as earth excavation, rock excavation, or subexcavation, or it may be unclassified as described below.

1. Unclassified Excavation: Excavation of all material, including rock, regardless of its nature or the manner in which it is removed. All excavation shall be unclassified unless explicitly and otherwise shown on the Drawings, or if unit pay items are provided for Rock Excavation, Earth Excavation, or Subexcavation.

2. Earth excavation or simply “Excavation”: Excavation of all material is except for active utilities and rock.

3. Rock excavation: Excavation of all hard, compacted, or cemented materials that require the use of drilling, blasting or wedging equipment to remove. It shall consist of un-decomposed stone hard enough to ring under a hammer, and the amount of solid stone shall not be less than one (1) cubic yard in volume. If applicable, rock is further defined as follows:

a. General Excavation (Mass): Any material occupying an original volume of more than one cubic yard which cannot be excavated with a single-tooth ripper drawn by a crawler tractor having a minimum draw bar pull rated at not less than 80,000 pounds

(Caterpillar D-8 or larger).

b. Trench Excavation: Any material occupying an original volume of more than one cubic yard which cannot be excavated with a hydraulic excavator having a minimum flywheel power rating of

123 kW (165 hp); such as a Caterpillar 322C L, John Deere

230C LC, or a Komatsu PC 220LC-7; equipped with a short tip radius bucket not wider than 42 inches.

4. Subexcavation: Authorized additional excavation below subgrade elevations or beyond indicated lines and dimensions as directed by

Design Professional or Testing Agency in writing.

C. Fills: Suitable materials placed to raise existing grades.

2. Pavement fill zone: The zone occupied by materials supporting asphalt or concrete paving supporting vehicular traffic or parking and extending for a distance of 4 feet on each side paving area measured at the finished grade (including gutter pans), thereafter tapering away at a 45° angle. Pavement fill zone for asphalt or concrete pedestrian areas are 2 feet on each side of paving area measured at finish grade and tapering down at a 45° angle.

3. Structural fill zone: The zone occupied by materials supporting floor slabs, building foundations or other structures and extending for a distance of 10 feet on each side of said structure measured at the finished grade, thereafter tapering away at a 45° angle.

(rainfall, storm runoff, ground water or other sources) shall not be considered as unsuitable.

b. Dewater or dry out water saturated soils to the extent necessary to satisfy the requirements for fill.

c. The Contractor is solely responsible for the scheduling and sequencing of the work. If necessary, to maintain the

Contractor’s schedule, wet soils shall be removed and replaced with suitable fill to replace water saturated soils. The removal and replacement of water saturated soils shall be performed at the Contractor’s expense.

2. Fill material placed on site by the Contractor, regardless of whether fill is on-site or off-site borrow, cannot by its nature, be classified as unsuitable soils.

a. Materials placed as fill shall not be classified as unsuitable soils regardless of conditions encountered, since only suitable soils shall be used as fill.

b. Fill shall be placed, compacted and tested as required by the

Contract documents.

c. The Contractor shall be responsible for maintaining compacted fill, in condition and at compaction levels required, until improvements (site and/or building) are placed on fill.
