ASTM D 2922 (2005) Density of Soil and Soil-Aggregate in Place by Nuclear Methods (Shallow Depth)

U.S. ARMY CORPS OF ENGINEERS (USACE)

ASTM D 3017 (2005) Standard Test Method for Water Content of Soil and Rock in Place by Nuclear Methods (Shallow Depth)

ASTM D 4643 (2008) Standard Test Method for Determination of Water Content of Soil by the Microwave

1.2 DEFINITIONS

1.2.1 Degree of Compaction

Degree of compaction is expressed as a percentage of the maximum density obtained by the test procedure presented in ASTM D 698, for general soil types, abbreviated as percent laboratory maximum density.

1.2.2 Hard Materials

Weathered rock, dense consolidated deposits, or conglomerate materials which are not included in the definition of "rock" but which usually require the use of heavy excavation equipment, ripper teeth, or jack hammers for removal.

1.2.3 Rock

Solid homogeneous interlocking crystalline material with firmly cemented, laminated, or foliated masses or conglomerate deposits, neither of which can be removed without systematic drilling and blasting, drilling and the use of expansion jacks or feather wedges, or the use of backhoe-mounted pneumatic hole punchers or rock breakers; also large boulders, buried masonry, or concrete other than pavement exceeding 1 cubic yard in volume.

Removal of hard material will not be considered rock excavation because of intermittent drilling and blasting that is performed merely to increase production.

The Project is located between river stations 241026.78 and 238695.56 for Samuels North and South sites. Cross-section of the river with elevations at these stations is presented at the end of this specification and is available electronically from the C.O. upon request. A tabular listing of river stage elevations and flows for various storm events is presented at the end of this section for use by the Contractor in establishing the site flood protection during the construction period.

SECTION 31 23 00.00 20 Page 4

3.3.1.1 Drainage

So that construction operations progress successfully, completely drain construction site during periods of construction to keep soil materials sufficiently dry. The Contractor shall establish/construct storm drainage features 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, dikes, swales, and other drainage features and equipment as required to maintain dry soils and prevent erosion. 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. Excavated slopes and backfill surfaces shall be protected to prevent erosion and sloughing.

Excavation shall be performed so that the site, the area immediately surrounding the site, and the area affecting operations at the site shall be continually and effectively drained.

3.3.2 Underground Utilities

The existence and location of underground utilities indicated on the plans are taken from available records. Contractor prior to the commencement of work shall verify the location and existence of utilities within the work zone. Any underground utilities not shown on the plans if encountered during construction will be treated as differing/changed conditions. Upon encountering any underground utilities the Contractor shall immediately notify the government and wait for further written instructions from the Contracting Officer.

3.3.3 Machinery and Equipment

Movement of construction machinery and equipment over pipes during construction shall be at the Contractor's risk. Repair, or remove and provide new pipe for existing or newly installed pipe that has been displaced or damaged.

3.4 SURFACE PREPARATION
