Standard Guide for Site Characterization for Engineering Design and Construction Purposes

Importancia y uso:

4.1 An adequate site characterization will provide pertinent information for decision making on one or more of the following subjects:

4.1.1 Location of the structure, both vertically and horizontally, within the area of the proposed construction and selection of construction methods and equipment.

4.1.2 Location and preliminary evaluation of suitable borrow and other local sources of construction aggregates.

4.1.3 Need for special excavating and dewatering techniques with the corresponding need for information, even if only approximate, on the distribution of soil water content or pore pressure, or both, and on the piezometric heads and apparent permeability (hydraulic conductivity) of the various subsurface strata.

4.1.4 Evaluation of slope stability in natural slopes, cuts, and embankments.

4.1.5 Conceptual selection of embankment types and hydraulic barrier requirements.

4.1.6 Conceptual selection of alternate foundation types and elevations of the corresponding suitable bearing strata.

4.1.7 Development of additional detailed site characterizations for specific structures or facilities.

4.2 The site characterization may require the collection of sufficiently large soil and rock samples of such quality as to allow adequate testing to determine the soil or rock classification or mineralogic type, or both, and the engineering properties pertinent to the proposed design.

4.3 This guide is not meant to be an inflexible description of requirements; methods defined by other ASTM standards or non-ASTM techniques may be appropriate in some circumstances. The intent is to provide a list to assist in preparation of a site characterization plan.
