Download or read book Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data written by and published by Amer Society of Civil Engineers. This book was released on 2003 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: CI/ASCE Standard 38-02 presents a credible system for classifying the quality of utility location information that is placed in design plans. The Standard addresses issues such as: how utility information can be obtained, what technologies are available to obtain that information; how that information can be conveyed to the information users; who should be responsible for typical collection and depiction tasks; what factors determine which utility quality level attribute to assign to data; and what the relative costs and benefits of the various quality levels are. Used as a reference or as part of a specification, the Standard will assist engineers, project and utility owners, and constructors in developing strategies to reduce risk by improving the reliability of information on existing subsurface utilities in a defined manner.
