To order asce 38-02 copy of the standard from the ASCE website, please click here. This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground utilities.
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 was common practice to design projects without consideration of any utilities and to then deal with them during construction. It sets out the accuracy to which the data is captured asce 38-02 specific purposes, the quality expected of asce 38-02 data and asce 38-02 means by which to assess and indicate the confidence that can be placed in the data.
The Standard ASCE
Civil engineering Geotechnical engineering. 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.
PAS applies to the detection, verification and location of active, abandoned, redundant or unknown underground utilities and associated surface features that facilitate asce 38-02 location and identification of underground utility infrastructure.
The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:. asce 38-02
Many countries followed the U. The practice of collecting, recording and managing subsurface data has historically been asce 38-02 unregulated.
Subsurface utility engineering
The Standard Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database. Non-destructive surface asce 38-02 methods are then leveraged to determine the presence of subsurface utilities and to mark asce 38-02 horizontal zsce on the ground surface. This article is an orphan asce 38-02, as no other articles link to it.
This provides project owners and engineers with a benchmark to determine the integrity of utility data at the outset of an infrastructure project. SUE is mainly used at the design stage of a capital works project and when information is being collected for asset management purposes. Quality Level A Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point. Quality Level D Information derived from existing records or oral recollections.
Interested in getting the latest industry news? Committed to Damage Prevention For initiatives involving asset management, project owners asce 38-02 be missing information about their underground utilities or have inaccurate data.
Orphaned articles from January Asce 38-02 orphaned articles. Learn more about the SUE process. The first concept is the means of classifying the reliability of the existence and location of utilities already installed and hidden in the ground. This ASCE standard presents a zsce to classify the quality of existing subsurface utility data. SUE began in the early s. The ASCE standard presents a system of asce 38-02 the quality of existing subsurface utility data.
Such a classification allows project owners, engineers, and constructors to develop strategies to reduce or allocate risks acse to existing subsurface utilities in asce 38-02 defined manner.
Developed and refined over the last 20 years, SUE classifies information according to quality levels with an objective to vastly asce 38-02 data reliability.
Quality Level B Information obtained 38-022 the application of appropriate surface geophysical techniques to determine the asce 38-02 and approximate horizontal position of subsurface utilities.
In June,the Standards Australia Committee IT on Subsurface Utility Engineering Information launched Standard Classification of Subsurface Utility Information to asce 38-02 utility owners, operators and locators with a framework for the consistent classification of information concerning subsurface utilities. Views Read Edit View history. Information obtained asve surveying and plotting visible above-ground utility features and by using professional judgement in correlating this information to Quality Level D.
Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location asce 38-02 the infrastructure. In this situation a SUE provider would collect the required information and add it to the asset management database, according to the asce 38-02 quality levels prescribed by ASCE Standard As 38-0 handout or as part of a specification, it assists engineers, owners, asce 38-02 contractors in understanding utility quality level classifications and their allocations of risk.
The different levels are described below:.
