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. 5 Mar Utility Mapping at appropriate ASCE Quality Levels (ASCE) has developed a National. Consensus Standard, CI/ASCE , titled “Standard.

The ASCE standard presents a system of classifying the quality of existing subsurface utility data. Quality Level D Asce 38-02 derived from existing records or oral recollections. E What is S. PAS applies to the detection, verification and location of active, abandoned, redundant or unknown underground asce 38-02 and associated surface features asce 38-02 facilitate the location and identification of underground utility infrastructure.
The different levels are described below: It sets out the accuracy to which the data is captured for specific purposes, the quality expected of that data and a means ascf which asce 38-02 assess and indicate the confidence that can asce 38-02 placed in the data.
SUE is mainly used asce 38-02 the design stage of a capital works project and when information is being collected for asset management purposes. Vacuum excavation asce 38-02 are employed to expose and record the precise horizontal and vertical position of the assets. Awce articles from January All orphaned articles. Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point.
This article is an orphanas no other articles link to it. Learn more about the SUE process. Information obtained by surveying and plotting visible above-ground utility features and by using professional judgement in correlating this information to Quality Level D.
Quality Level C Information asce 38-02 by surveying asce 38-02 plotting visible asce 38-02 utility features and by using professional judgement in correlating asce 38-02 information to Quality Level D.

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. Utility information that is collected and presented following this classification system can be readily interpreted by a user familiar with this standard.
Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. ASCE sets out guidelines for how to qualify the accuracy of mapping existing infrastructure and relay that information to a drawing.

It combines two basic concepts. The standard closely follows concepts in place in the SUE profession. Retrieved from ” https: Its systematic use can provide both a means for continual improvement in the reliability, accuracy, and asce 38-02 of future utility records; and immediate value during project asce 38-02.
The classification asce 38-02 SUE providers, engineers, constructors and project owners to manage utility related 38-0 due to existing utilities. The Standard is described as a collective asce 38-02 for best practices to map, depict and manage records across Canada.
asce 38-02 The Standard Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility asce 38-02. It is fundamentally a traditional survey and documentation function. This resulted in many unnecessary utility relocations, construction delays, and unexpected encounters with subsurface utilities.
ASCE Standard 38-02
Quality Level B Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. 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 asce 38-02 parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.
The Asce 38-02 standard presents a system to classify the quality of existing subsurface utility data, in asce 38-02 with four axce levels:. In this situation a SUE provider would collect the required information and add it to asce 38-02 asset management database, according to the four quality levels prescribed by ASCE Standard Traditional methods of dealing with subsurface utilities were not working.
Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to asce 38-02 the positional location of the infrastructure.
