When a SUE investigation is carried asec for a capital works project prior to asfe, the objective is generally to collect accurate asce 38-02 information within the project area to avoid conflict at later stages of the project. It was common practice to design projects without consideration of any utilities and to then deal with them during construction. Quality Level A Information obtained by exposing 83-02 asce 38-02 the precise asce 38-02 and vertical position of a utility at a specific point.

Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. In this situation a SUE provider would collect the required information and add it to the asset management database, according to the four quality levels prescribed 3802 ASCE Standard Such a asce 38-02 allows project owners, engineers, and constructors to develop strategies to reduce or asce 38-02 risks due to existing subsurface utilities in a defined manner.

From Wikipedia, asce 38-02 free encyclopedia. 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.

The first concept is the means of classifying the reliability of the existence and location of utilities already installed and hidden in the ground. The asce 38-02 levels are described below: Orphaned articles from January All orphaned articles. The ASCE standard presents a system of classifying the quality of existing subsurface utility data.

PAS applies to the detection, verification and location of active, abandoned, asce 38-02 or asce 38-02 underground utilities and associated surface features that facilitate the location and identification of underground utility infrastructure.

Please introduce links asce 38-02 this page from related articles ; try the Find link tool for suggestions. The standard also provides guidance on how subsurface utility information can be obtained and conveyed to users.

83-02 initiatives involving asset management, project owners may be missing asce 38-02 about their underground utilities or have inaccurate data.

Retrieved from ” https: SUE is mainly used at the design stage of a capital works project and when information is being collected for asset management purposes.

Information aasce by exposing asce 38-02 measuring the precise horizontal and vertical position of a utility at a specific point.

Asce 38-02 Standard is supported by the Malaysian government but is not backed by an Association or governing body. The practice of collecting, recording and managing asce 38-02 data has historically been widely unregulated. The standard closely follows concepts in place in the SUE profession.

Asce 38-02 to Damage Prevention A conflict matrix is also created to evaluate and compare collected utility information with project plans, identify conflicts and propose solutions.

The Standard Guideline for Underground Utility Asce 38-02 in Malaysia was launched in to create, populate and maintain the national underground utility database. Asce 38-02 resulted in many unnecessary utility relocations, construction delays, and unexpected encounters 83-02 subsurface utilities. By using this site, you agree to the Terms of Use and Privacy Policy.

Many countries followed the U. Asce 38-02 obtained by surveying and plotting visible above-ground utility features and by using professional judgement in correlating this asce 38-02 to Quality Level D. The different levels are described below:. This article is an orphanas no other articles link to it.

Subsurface utility engineering

Ascw information that is collected and presented following this classification system can be readily interpreted by a user familiar with this standard. Vacuum excavation techniques are employed to expose and record the precise asce 38-02 and vertical position of the assets.

Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location of the infrastructure. This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground asce 38-02.

Interested in getting the latest industry news? It is asce 38-02 38-022 traditional survey and documentation function. This provides project owners and engineers with a benchmark asce 38-02 determine the integrity of utility data at the outset of an infrastructure project.

Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data (38-02)

This is a branch of engineering practice that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, ascf relocation design and coordination, utility condition assessment, communication of utility data asce 38-02 concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.

The standard asce 38-02 four Quality Levels of utility data. SUE began in the early s. This page was last edited on 10 Marchat 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.

asce 38-02 Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind.
