    New Test Methods for Testing the Inclination of Deep Foundations

    (What is a Work Item?)

    Developed by Subcommittee: D18.11 | Committee D18 | Contact Staff Manager


    1. Scope

    1.1 These test methods measure the inclination of deep foundations including bored piles, drilled shafts, diaphragm walls, sheet piles, and driven piles. In these test methods, all of the above mentioned will be designated pile. The test, which measures the amount by which the pile axis deviates from its planned location, is performed in either the finished hole before the reinforcement is inserted or in the finished pile through access tubes or both. 1.2 Units--The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.3 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. 1.4 The methods used to specify how data are collected, calculated, or recorded in these test methods are not directly related to the accuracy to which data can be applied in design or other uses or both. How one applies the results obtained using these test methods are beyond their scope. 1.5 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.

    No such standard is known to exist for non-mechanical testing of deep foundation element verticality. Several new products now exist with multiple users employing various techniques.

    The title and scope are in draft form and are under development within this ASTM Committee.
