Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data (38-02)
This page was last edited asce 38-02 10 Marchat This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground utilities. Orphaned asce 38-02 from January All orphaned articles. A 38-2 matrix is also created to evaluate and compare collected utility information with project plans, identify conflicts and propose solutions.
Utility information that is collected and presented asce 38-02 this classification system can be readily interpreted by a user familiar with this standard. The standard also provides guidance on how subsurface utility information can be obtained asce 38-02 conveyed to users. SUE began in the early s.
Its systematic use can provide both asce 38-02 means for continual improvement in the reliability, accuracy, and precision of future utility records; and immediate value during project development. Asce 38-02 applies to the detection, verification and location of active, abandoned, redundant or ascee underground utilities and associated surface asce 38-02 that facilitate the location and identification of underground utility infrastructure.
Committed to Damage Prevention Traditional methods of dealing with subsurface utilities were not working. The ASCE standard presents asce 38-02 system of classifying asce 38-02 quality asce 38-02 existing subsurface utility data. The standard defines four Quality Levels of utility data. Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface 38-20.
From Wikipedia, the free encyclopedia. To order a copy of the standard from the ASCE website, please click here. Quality Level B Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. For initiatives involving asset management, project owners may be missing information about their underground utilities or have inaccurate 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 concerned parties, utility relocation asce 38-02 estimates, implementation of asce 38-02 accommodation policies, and utility design. SUE is mainly used at the design stage of a capital aasce project asce 38-02 when information is being collected for asset management purposes.
It is used primarily during utility installation. Many countries followed the U. ASCE sets out guidelines for how 38-002 qualify the accuracy of mapping existing infrastructure and relay that information to a drawing.
Developed and refined over asce 38-02 last 20 years, SUE classifies information according to quality levels with an objective to vastly improve data reliability. Information obtained by surveying and plotting visible above-ground utility features and by using professional judgement in correlating this information to Quality Level D. E What is S. It was common practice to design projects without consideration of any utilities and to then asce 38-02 with them during construction.

It combines two basic 38-022. Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind. Such a classification allows project owners, engineers, and constructors to develop strategies to reduce or allocate risks due to existing subsurface utilities in a defined manner.

ASCE Standard 38-02
This is asxe branch of engineering practice that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, asce 38-02 of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.
The Standard Guideline for Asce 38-02 Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database.
Asce 38-02 article is an orphanas no asce 38-02 articles link to it. The Standard is supported by the Malaysian government but is not backed by an Association or governing body. Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets.
The different levels are described below: The standard closely follows concepts in place in the SUE profession.
As a handout or as part of a specification, it assists engineers, owners, and contractors asce 38-02 understanding utility quality level classifications and their allocations of risk. When a SUE investigation is carried out asce 38-02 a capital works project prior 388-02 construction, the objective is generally to collect accurate utility information within the project area to avoid conflict at later stages of the project.
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 asce 38-02 facilities including utilities. In this situation a SUE provider would collect the required information and add it to the asset asce 38-02 database, 380-2 to the four quality levels prescribed by ASCE Standard Non-destructive surface geophysical methods are then leveraged to determine the presence of subsurface utilities and to mark their asce 38-02 position on the ground asce 38-02.
The practice of collecting, recording and 38-0 subsurface data has historically been widely unregulated. Quality Level D Information derived from existing records or oral recollections.
