The underground utility infrastructure of the USA and most parts of the developed world is vast, complicated and continues to grow at a rapid pace.

This activity is called “locating.

This information, when awce with other surveyed and mapped information, allows the designer to infer plan and profile information, for use in making final design decisions. SUE began in the early s. 38-0 such approval is obtained, the Agreements Office will coordinate issuance of the Notice to Proceed letter with the Region. Preliminary utility information gathering; Visual observation and surveying of above-ground utility facilities; Surface marking of buried utilities; Exposing and surveying the location of buried utility facilities; Utility facility mapping and CADD drawings; Utility relocation planning and design.

From Wikipedia, the free encyclopedia. Subsurface Utility Engineering – Part 2: Engineer, Land Surveyor on January 12, The course also elaborates on some of the subject matter and the techniques used in the acquisition zsce utility data.

Subsurface utility engineering – Wikipedia

Developed and refined over the last 20 years, SUE classifies information according to quality levels with an objective to vastly improve data reliability. 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. 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.

Quality Level A Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point.


Subsurface Utility Engineering – Part 2: Understanding CI/ASCE

Identify the quality levels of SUE. It further correlates utility records and surface topographical information, and may also help reveal unrecorded lines. Home About Us About S. Support Sign In 0. However, it is not necessary to have taken that course prior to this one.

Many countries followed the U. Singer has worked as a subsurface utility engineer or a utility relocations design engineer. The consultant may not proceed with any work until the NTP letter has been sent out.

Subsurface utility engineering

A Professional Engineer’s Standard of Care 1 hour. Each Quality Level represents an improvement over the previous level D the lowest, A the highest. Views Read Edit View history. The SUE process begins with a work plan that outlines the scope of work, project schedule, levels of service vs.

Quality Level B “QL B” involves the use of surface geophysical techniques to determine the existence and horizontal position of underground utilities. Utility information that is collected and presented following this classification system can be readily interpreted by a user familiar with this standard.

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.

No formal procedure has been established for CDOT personnel asde follow in selecting one consultant versus the other for wsce particular project, but over the term of the two NPS contracts 2 yearsapproximately equal utilization of each firm is desirable. As a handout or as part of a acse, it assists engineers, owners, and contractors in understanding utility quality level classifications and their allocations of risk.

In both situations, a similar process is followed but the scope of the work and aece of the information may vary. It proceeds through the Standard emphasizing key aspects and providing well-rounded explanations of the concepts. Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point. PAS applies to the detection, verification and location of active, abandoned, redundant or unknown underground utilities and associated surface features that facilitate the location and identification of underground utility infrastructure.


The Standard is described as a collective framework for best practices to map, depict and 38-0 records across Canada. Video works better than text. 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. 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 ase the consistent classification of information concerning subsurface utilities.

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. Therefore, its usefulness may be limited to preliminary design reviews or to projects with minimal anticipated conflicts.

For initiatives involving asset management, project owners may be missing asc about their underground utilities or have inaccurate data. This page was last edited on 10 Marchat Engineer 38-2 December 27, very detailed Thanks By zaki W.

Explain the responsibility of the project owner, engineer, subsurface utility engineer and utility owner relative to existing utilities on construction projects. Ten Tips for Green Building Certification 1 hour. Learn more about the SUE process.

Slight adjustments in the design may produce substantial cost savings ascee eliminating utility relocations. The standard defined SUE and set guidance for the collection and depiction of subsurface utility information. This article is an orphanas no other articles link to it. It combines two basic concepts.

The different levels are described below: It is used primarily during utility installation.
