ASTM WK36598

    New Guide for Site Characterization for Engineering Design and Construction Purposes

    (What is a Work Item?)

    Developed by Subcommittee: D18.01 | Committee D18 | Contact Staff Manager


    1. Scope

    1.1 This guide refers to ASTM methods by which soil, rock, and groundwater conditions may be determined. The objective of the investigation should be to identify and locate, both horizontally and vertically, significant soil and rock types and groundwater conditions present within a given site area and to establish the characteristics of the subsurface materials by sampling or in situ testing or both. 1.2 Laboratory testing of soil, rock, and groundwater samples is specified by other ASTM standards not listed herein. Subsurface exploration for environmental purposes will be the subject of a separate ASTM document. 1.3 Before commencement of any intrusive exploration, the site should be checked for potentially hazardous or otherwise contaminated materials or conditions including underground utilities. Should evidence of potentially hazardous or otherwise contaminated materials or conditions be encountered in the course of the investigation, work should be interrupted until the circumstances have been evaluated and revised instructions issued before resumption. 1.4 The values stated in SI units are to be regarded as the standard. Inch-pound units are provided in parentheses for convenience. 1.5 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This guide cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service shall be judged, nor should this guide be applied without consideration of a projects many unique aspects. The word Standard in the title of this guide means only that the guide has been approved through the ASTM consensus process. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    This standard activity is to reinstate D420 (of the same title) with revisions based on Main Committee Ballot 10-01.
