The Standard ASCE 38-02

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. The course begins by discussing the history behind the development of the Standard.

Therefore, its usefulness may be limited to preliminary design reviews or to projects with minimal ascr conflicts. This resulted in many unnecessary utility relocations, construction delays, and unexpected encounters with subsurface utilities.

It is not appropriate to contact both consultants with the intention of soliciting competing cost estimates. Developed and refined over the last 20 years, SUE classifies information according to quality levels 3802 an objective to vastly improve data reliability. By knowing exactly where a utility is positioned in three dimensions, the designer can accurately determine ascr extent of a utility conflict, or can often make small adjustments in elevations or horizontal locations and avoid the need to relocate utilities.

Civil engineering Geotechnical engineering.

S.U.E. Subsurface Utility Engineering —

Its systematic use can provide 3-02 a means for continual improvement in the reliability, accuracy, and precision of future utility records; and immediate value during project development. The concept of SUE is gaining popularity worldwide as a framework to mitigate costs associated with project redesign and construction delays and to avoid risk and liability that can result from damaged underground utilities.

Quality Level A Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point. Singer has worked as a subsurface utility engineer or a utility relocations design engineer. Professional Organizations No results found.

Please introduce links to this page from related articles ; try the Find link tool for suggestions. Committed to Damage Prevention Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets.

Engineer, Land Surveyor on January 12, Photo examples ascf be a good addition showing the surveys taking place By Scott D. Subsurface Utility Engineering – Part 2: Singer is also an instrument rated pilot.

Additional information such as utility material, condition, size, soil contamination, and paving thickness also assists the designer and utility owner in their decisions. A conflict matrix is also created to evaluate and compare collected utility information with project plans, identify conflicts and propose solutions. 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 the data.

Compare the various techniques used to acquire utility locations.

Thanks By zaki W. The consultant may not proceed with any ace until the NTP letter has been sent out. Click on the Quality Levels tab above for definitions.

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. Should be a video presentation. This page was last edited on 10 Marchat This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground utilities.

Subsurface Utility Engineering – Part 2: Understanding CI/ASCE 38-02

Traditional methods of dealing with subsurface utilities were not working. This information, when combined with other surveyed and mapped information, allows the designer to infer plan and profile information, for use in making final design decisions. The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:. From Wikipedia, the free encyclopedia. This acse is called “designating”. The different levels are described below:.

It is the ultimate responsibility of the individual to be sure that he 380-2 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.

In choosing which consultant to use, factors such as specific consultant capabilities, and the ability of the consultant to meet desired timeframes for wsce and completing the SUE work may be considered. Quality Level D Information derived from existing records or oral recollections. The course also elaborates on aace of the subject matter and the techniques used in the acquisition of utility data. In June,the Standards Australia 3-02 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.
