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.

Singer has worked as a subsurface utility engineer or a utility relocations design engineer.

Photo examples would be a good addition showing the surveys taking place By Scott D. By using this site, you agree to the Terms of Use and Privacy Policy. In this situation a SUE provider would collect the required information and add it to the fi management database, according to the four quality levels prescribed by ASCE Standard Civil engineering Geotechnical engineering. It is used primarily during utility installation. Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets.

The standard also provides guidance on how subsurface utility information can be obtained and conveyed to users.

Subsurface Utility Engineering – Part 2: Understanding CI/ASCE

For initiatives involving asset management, project owners may be missing information about their underground utilities or have inaccurate data. Subsurface Utility Engineering – Part 1: Engineer, Land Surveyor on January 12, Should be a video presentation. 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.

State Licenses No results found.

A conflict matrix is also created to evaluate and compare collected utility information with project plans, identify conflicts and propose solutions. The Standard is described as a collective framework 3-802 best practices to map, depict and manage records across Canada. Click on the state to expand the license or professional organization that applies to the course.

The practice of collecting, recording and managing subsurface data has historically been widely unregulated. 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.


Many countries followed the U. The course also elaborates on some of the subject matter and the techniques used in the acquisition of utility data.

The Standard is supported by the Malaysian government but is not backed by an Association or asde body. Identify the quality levels of SUE. Engineer on December 27, The appropriate use of SUE services can prevent these problems. This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground utilities. Engineer, Land Surveyor on January 12, Retrieved from ” https: Should be a video presentation.

It combines two basic concepts. The course begins by discussing the history behind the development of the Standard.

Explain the responsibility of the project owner, engineer, subsurface utility engineer and utility owner relative to existing utilities on construction projects.

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

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 aasce assess and indicate the confidence that can be placed in the data.

Subsurface Utility Engineering – Part 2: Video works better than text.

The Standard Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database. 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.

However, it is not necessary to have taken that course prior to this one. Subsurface Utility Engineering SUE refers to a branch of engineering 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.


Engineer on December 27, very detailed Thanks By zaki W. Terms and Conditions Privacy Policy iadd. Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define ascd positional location of the infrastructure.

It is fundamentally a traditional survey and documentation function. Please introduce links to this page from related articles ; try the Find link tool for 38-2.

The standard defined SUE and set guidance for the collection and depiction of subsurface utility information. This page was last edited on 10 Marchat 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.

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. 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.

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. From Wikipedia, the free encyclopedia. Compare the various techniques used to acquire utility locations.

This provides project owners and engineers with a benchmark to determine the integrity of utility data at the outset of an infrastructure project. Recognize the original individuals involved in the development of SUE.

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.
