As a handout or as part of a specification, it assists engineers, owners, and contractors in understanding utility quality level classifications and their allocations of risk. The standard defined SUE and set guidance for the collection and depiction of subsurface utility information. Non-destructive surface geophysical methods are then leveraged to determine the presence of subsurface utilities and to mark their horizontal position on the ground surface. Recognize the original individuals involved in the development of SUE.
Support Sign In 0. This is a branch of engineering practice that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of asve data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.
The ASCE standard presents a system of classifying the quality of existing subsurface utility data.
Subsurface utility engineering
In both situations, a similar process is followed but the scope of the work and presentation of the information may vary. This resulted in many unnecessary utility relocations, construction delays, and unexpected encounters with subsurface utilities.
This article is an orphanas no other articles link to it. Information obtained through the application of appropriate surface geophysical techniques to sace the existence and approximate horizontal position of subsurface utilities.
Many countries followed the U. Learn more about the SUE process.
Views Read Edit View history. Click on the state to expand the license or professional organization that applies to the course. It sets out the accuracy to which the data is captured for specific purposes, the quality expected of that data and a means by which to assess and indicate the confidence that can be placed in ace data.
Engineer, Land Surveyor on January 12, Orphaned articles from January All orphaned articles. The first concept is the means of classifying the reliability of the existence and location of utilities already installed and hidden in the ground. Quality Level C Information obtained by surveying and plotting visible above-ground utility features and by using professional judgement in correlating this information to Quality Level D. This page ssce last edited on 10 Marchat The Standard is supported by the Malaysian government but is not backed by an Association or governing body.
Quality Level B Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. State license renewal information is provided as a convenience only and is subject to change at any qsce. Retrieved from ” https: The standard also provides guidance on how subsurface utility information can be obtained and conveyed to users.
From Wikipedia, the free encyclopedia. Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to aece the positional location of the infrastructure.
Utility information that is collected and presented following this classification system can be readily interpreted by a user familiar with this standard.
SUE began in the early s. Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets. In June,the Standards Australia Committee IT on Subsurface Utility Engineering Information launched Standard Classification of Subsurface Utility Information to provide utility owners, operators and locators with a framework for the consistent classification of information concerning subsurface utilities.
The appropriate use of SUE services can prevent these problems. Video works better than text. Engineer, Land Surveyor on January 12, Should be a video presentation.

Please ascd links to this page from related articles ; try the Find link tool for suggestions. Home About Us About S. Evaluate the cost savings realized by using SUE.
It is used primarily during utility installation. Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind.
Subsurface Utility Engineering – Part 2: Understanding CI/ASCE
Its systematic use can provide both a means for continual improvement in the reliability, accuracy, and precision of future utility records; and immediate value during project development.
The classification allows SUE providers, engineers, constructors and project owners to manage utility related risks due to existing utilities. Identify the quality levels of SUE. The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:. Thanks By zaki W. Define several terms used in the SUE industry. This ASCE standard presents a system to classify the quality of existing subsurface utility data.
Such a classification allows project owners, engineers, and constructors to develop strategies to reduce or allocate risks due to existing subsurface utilities in a defined manner. Information obtained by surveying and plotting visible above-ground utility features and by using professional judgement in correlating this information to Quality Level D.
The Standard Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database. It is fundamentally a traditional survey and documentation function. Subsurface Utility Engineering SUE refers to a branch of engineering that involves managing certain risks aece with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility 3802 to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.
