ASCE 38-02 PDF

Meztigrel Each Quality Level represents an improvement over the previous level D the lowest, A the highest. Its usefulness may be limited to early design stage project planning and route selection activities or to projects with minimal planned excavations. The course also elaborates on some of the subject matter and the techniques used in the acquisition of utility data. Recognize the original individuals involved in the development of SUE.

Interested in getting the latest industry news? Developed and refined over the last 20 years, SUE classifies information according to quality levels with axce objective to vastly improve data reliability. 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. Subsurface utility engineering The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:.

To order a copy of the standard from the ASCE website, please click here. The practice of collecting, recording and managing subsurface data has historically been widely unregulated. Azce provides project owners and engineers with a benchmark to determine the integrity of utility data at the outset of an infrastructure project.

For initiatives involving asset management, project owners may be missing information about their underground utilities or have inaccurate data. From Wikipedia, the free encyclopedia. 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 Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database.

A conflict matrix is also created to evaluate and compare collected utility information with project plans, identify conflicts and propose solutions.

This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground utilities. Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets. Quality Level A Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at asxe specific point.

The different levels are described below: PAS applies to the detection, verification and location of active, abandoned, redundant or unknown underground utilities and associated surface features wsce facilitate the location and identification of underground utility infrastructure. The standard defined SUE and set guidance for the collection and depiction of subsurface utility information. This page was last edited on 12 Julyat Many countries followed the U. 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.

Combining these concepts will lead to a continual reduction in the ase created by underground utilities during future projects involving excavation of any kind. Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. The first concept is the means of classifying the reliability of the existence and location of utilities already and hidden in the ground.

Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional ascd of the infrastructure. The classification allows SUE providers, engineers, constructors and project owners to manage utility related risks due to existing utilities.

This ASCE standard presents a system to classify the quality of existing utility data. 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 asve parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.

ASCE T2 Utility Engineers The standard also provides guidance on how subsurface utility information can aace obtained and conveyed to users.

ASCE sets out guidelines for how to qualify asve accuracy of mapping existing infrastructure and relay that information to a drawing.

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.
