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.
When a SUE investigation is carried out for a capital works project prior to construction, the objective is generally to collect accurate utility information within the project area to avoid conflict at later stages of the project. It proceeds through the Standard emphasizing key aspects and providing well-rounded explanations of the concepts. Subsurface Utility Engineering – Part 2: To order a copy of the standard from the ASCE website, please click here.
It was common practice to design projects without consideration of any utilities and to then deal with them during construction. The classification allows SUE providers, engineers, constructors and project owners to manage utility related risks due to existing utilities. 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.
Home About Us About S. The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:.
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 utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.
This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground utilities. In this situation a SUE provider would collect the required information and add it to the asset management database, according to the four quality levels prescribed by ASCE Standard For initiatives involving asset management, project owners may be missing information about their underground utilities or have inaccurate data.
SUE began in the early s. 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 Standard ASCE
Photo examples would be a good addition showing the surveys taking place By Scott D. Singer has worked as a subsurface utility engineer or a utility relocations design engineer. This resulted in many unnecessary utility relocations, construction delays, and unexpected encounters with subsurface utilities.
Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location of the infrastructure. Thanks By zaki W. With this massive web of active and abandoned underground utility systems in place, all new excavations are at risk of encountering unplanned utility conflicts and causing potential damage.
The Standard is described as a collective framework for best practices to map, depict and manage records across Canada. Ace Organizations No results found. The different levels are described below:. The first concept is the means of classifying the reliability of the existence and location of utilities already installed and hidden in the ground.

Interested in getting the latest industry news? Singer is also an instrument rated pilot. Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets. The ASCE standard presents a system of classifying the quality of existing subsurface utility data. State license renewal information is provided as a convenience only and is subject to change at any time.
Learn more about the SUE process. Engineer, Land Surveyor on January 12, Should be a video presentation. SUE is mainly used at the design stage of a capital works project and when information is being collected for asset management purposes.
In both situations, a similar process is followed but the scope of the work and presentation of the information may vary. ASCE sets out guidelines for how to qualify the accuracy of mapping existing infrastructure and relay that information to a drawing. This page was last edited on 10 Marchat From Wikipedia, the free encyclopedia. Define several terms used in the SUE industry. 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 course also elaborates on some of the subject matter and the techniques used in the acquisition of utility data.

The different levels are described below: This article is an orphanas no other articles link to it. Quality Level B Information obtained through the application of appropriate surface geophysical 3802 to determine the existence and approximate horizontal position of subsurface utilities. Evaluate the cost savings realized by using SUE. The standard also provides guidance on how subsurface utility information can be obtained and conveyed to users.
Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind. The Standard Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database.
Recognize the original individuals involved in the development of SUE. It is the ultimate responsibility of the individual to be sure that he or she is meeting continuing education requirements for each license and corresponding renewal period.
Utility information that is collected and presented following this classification system can be readily interpreted by a user familiar with this standard.
