Accreditation by ANSI, a voluntary accreditation body representing public and private sector standards development organizations in the U.S. and abroad, signifi es that the standards develop- ment process used by ASCE has met the ANSI requirements for openness, balance, consensus, and due process. While ASCE’s process is designed to promote standards that refl ect a fair and reasoned consensus among all interested participants, while preserving the public health, safety, and welfare that is paramount to its mission, it has not made an independent assessment of and does not warrant the accuracy, completeness, suitability, or utility of any infor- mation, apparatus, product, or process discussed herein. ASCE does not intend, nor should anyone interpret, ASCE’s standards to replace the sound judgment of a com- petent professional, having knowledge and experience in the appropriate fi eld(s) of practice, nor to substitute for the standard of care required of such professionals in interpreting and applying the contents of this standard.
