Measurements Procedures

Excavation: the unit of measurement for excavation and borrow will be the cubic meter, computed by the average end area method from cross sections taken before and after the excavation and borrow operations, including the excavation for ditches, gutters, and channel changes, when the material is acceptably utilized or disposed of as herein specified. The measurements will include authorized excavation of rock (except for piping trenches that is covered below), authorized excavation of unsatisfactory subgrade soil, and the volume of loose, scattered rocks and boulders collected within the limits of the work; allowance will be made on the same basis for selected backfill ordered as replacement. The measurement will not include the volume of subgrade material or other material that is scarified or plowed and reused in-place and will not include the volume excavated without authorization or the volume of any material used for purposes other than directed.

Stripping of Topsoil

Where indicated or directed, strip topsoil to a depth of 100 mm. Spread topsoil on areas already graded and prepared for topsoil or transported and deposited in stockpiles convenient to areas that are to receive application of the topsoil later, or at locations indicated or specified. Keep topsoil separate from other excavated materials, brush, litter,

- 20 -objectionable weeds, roots, stones larger than 50 mm in diameter, and other materials that would interfere with planting and maintenance operations. Stockpile in locations indicated or remove from the site if indicated, any surplus of topsoil from excavations and gradings.

General Excavation

Perform excavation of every type of material encountered within the limits of the project to the lines, grades, and elevations indicated and as specified. Transport satisfactory excavated materials and place in fill or embankment within the limits of the work. Excavate unsatisfactory materials encountered within the limits of the work below grade and replace with satisfactory materials as directed. Include such excavated material and the satisfactory material ordered as replacement in excavation. Dispose surplus satisfactory excavated material not required for fill or embankment in areas approved for surplus material storage or designated waste areas. Dispose unsatisfactory excavated material in designated waste or spoil areas. During construction, perform excavation and fill in a manner and sequence that will provide proper drainage at all times. Excavate material required for fill or embankment in excess of that produced by excavation within the grading limits from the borrow areas indicated or from other approved areas selected by the

Contractor as specified.

Drainage

Provide for the collection and disposal of surface and subsurface water encountered during construction. Completely drain construction site during periods of construction to keep soil materials sufficiently dry. Construct storm drainage features (ponds/basins) at the earliest stages of site development, and throughout construction grade the construction area to provide positive surface water runoff away from the construction activity [and] [or] provide temporary ditches, swales, and other drainage features and equipment as required to maintain dry soils. When unsuitable working platforms for equipment operation and unsuitable soil support for subsequent construction features develop, remove unsuitable material and provide new soil material as specified herein. It is the responsibility of the Contractor to assess the soil and ground water conditions presented by the plans and specifications and to employ necessary measures to permit construction to proceed.

Removal of Unstable Material

Where unstable material is encountered in the bottom of the excavation, remove such material to the depth directed and replace it to the proper grade with select granular material.

- 21 -

Underground Utilities

The Contractor is responsible for movement of construction machinery and equipment over pipes and utilities during construction. For work immediately adjacent to or for excavations exposing a utility or other buried obstruction, excavate by hand. Start hand excavation on each side of the indicated obstruction and continue until the obstruction is uncovered or until clearance for the new grade is assured. Report damage to utility lines or subsurface construction immediately to the Contracting Officer Representative.

Ground Surface Preparation

General Requirements Remove and replace unsatisfactory material with satisfactory materials, as directed by the Contracting Officer Representative, in surfaces to receive fill or in excavated areas. Scarify the surface to a depth of 400 mm before the fill is started.

Pulverize, and compact to the specified density. When the subgrade is part fill and part excavation or natural ground, scarify the excavated or natural ground portion to a depth of 400 mm and compact it as specified for the adjacent fill.

Utilization of Excavation Material

Dispose unsatisfactory materials removing from excavations into designated waste disposal or spoil areas. Use satisfactory material removed from excavations, insofar as practicable, in the construction of fills, embankments, subgrades, shoulders, bedding (as backfill), and for similar purposes. Submit procedure and location for disposal of unused satisfactory material. Do not waste any satisfactory excavated material without specific written authorization. Dispose of satisfactory material, authorized to be wasted, in designated areas approved for surplus material storage or designated waste areas as directed. Clear and grub newly designated waste areas on Government-controlled land before disposal of waste material thereon. Stockpile and use coarse rock from excavations for constructing slopes or embankments adjacent to streams, or sides and bottoms of channels and for protecting against erosion. Do not dispose excavated material to obstruct the flow of any stream, endanger a partly finished structure, impair the efficiency or appearance of any structure, or be detrimental to the completed work in any way.

Backfilling and Compaction

Places backfill adjacent to all types of structures, in successive horizontal layers. Compact to at least 90 percent laboratory maximum density for cohesive materials or 95 percent laboratory maximum density for cohesionless materials, to prevent wedging action or eccentric loading upon or against the structure. Backfill material must be within the range of -2 to +2 percent of optimum moisture content at the time of compaction. Prepare ground

- 22 -surface on which backfill is to be placed and provide compaction requirements for backfill materials in conformance with the applicable portions of paragraphs.

Finish compaction by sheepsfoot rollers, pneumatic-tired rollers, steel-wheeled rollers, vibratory compactors, or other approved equipment.

Replacement of Unyielding Material Replace unyielding material removed from the bottom of the excavation with select granular material or initial backfill material.

Replacement of Unstable Material Replace unstable material removed from the bottom of the excavation with select granular material placed in layers not exceeding 150 mm loose thickness.

Bedding and Initial Backfill Place initial backfill material and compact it with approved tampers. Take care to ensure thorough compaction of the fill.

Provide materials as follows:

• Coarse sands and gravels with maximum particle size of 40 mm, including various graded sands and gravels containing small percentages of fines, generally granular and non cohesive, either wet or dry.

• Sand, Clean, coarse-grained sand

• Gravel and Crushed Stone

Rock Embankments

Construct rock embankments from material classified as rock excavation, as defined above, placed in successive horizontal layers of loose material not more than 200 mm in depth. Do not use pieces of rock larger than 100 mm in the greatest dimension. Spread each layer of material uniformly, completely saturate, and compact. Adequately bond each successive layer of material to the material on which it is placed. Finish compaction with vibratory compactors, heavy rubber-tired rollers, or steel-wheeled rollers weighing.
