ASCE Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data. The American Society of Civil Engineers (ASCE) has developed a National Consensus Standard titled ASCE C-I , Standard Guidelines for the Collection. This 2-hour interactive online course discusses the American Society of Civil Engineer’s Standard CI/ ASCE ‘Standard Guideline for the Collection and.

Retrieved from ” https: This provides project owners and engineers with a benchmark to determine the integrity of utility data at the outset of an infrastructure project. Singer has worked as a subsurface utility engineer or a utility relocations design engineer. PAS applies to the detection, verification and location of active, abandoned, redundant asfe unknown underground utilities and associated surface features that facilitate the location and identification of underground utility infrastructure.

It is fundamentally a traditional survey and documentation function. With this massive web of active and abandoned underground utility systems in ascd, all new excavations are at risk of encountering unplanned utility conflicts and causing potential damage. The cu 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.

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.

It combines two basic concepts. Video works better than text. The appropriate use of SUE services can prevent these problems.

For initiatives involving asset management, project owners may be missing information about their underground utilities or have inaccurate data. Views Read Edit View history. The underground utility infrastructure of the USA and most parts of the developed world is vast, complicated and ascw to grow at a rapid pace.

Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location of the infrastructure.

This page was last edited on 10 Marchat Singer is also an instrument rated pilot. 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.


The Standard is supported by the Malaysian government but is not backed by an Association or governing body. The first concept is the means of classifying the reliability of the existence and location of utilities already installed and hidden in the ground.

Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind.

It is used primarily during utility installation.

The course begins by discussing the history behind the development of the Standard. Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets. Explain the responsibility of the project owner, 38-0, subsurface utility engineer and utility owner relative to existing utilities on construction projects.

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. Developed and refined over the last 20 3802, SUE classifies information according to quality levels with an objective to vastly improve data fi.

Thanks By zaki W. 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 acse utilities.

Professional Organizations No results found. Subsurface Utility Engineering – Part 1: The Standard is described as a collective framework for best practices to map, depict and manage records across Canada. This standard addresses issues such as roles of stakeholders and how utility information can be obtained, and was a call to action from the Malaysian government due to increasing demands for improvements on basic infrastructure facilities including utilities.


The practice of collecting, recording and managing subsurface data has historically been widely unregulated. State license renewal information is provided as a convenience only and is subject to change at any time.

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.

The standard defined SUE and set guidance for the collection and depiction of subsurface utility information.

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.

In this situation a SUE provider would collect the cci information and add it to the asset management database, according to the four quality levels prescribed by ASCE Standard The SUE process begins with a work plan that outlines the scope of work, project schedule, levels of service vs.

The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:. In both situations, a similar process is followed but the scope of the work and presentation of the information may vary. Should be a video presentation. Many countries followed the U.
