The ASCE standard presents a system of classifying the quality of asce 38-02 subsurface utility data. 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 by asce 38-02 to assess and asce 38-02 the confidence that can be placed in the data. Civil engineering Geotechnical engineering. In both situations, a similar process is followed but the scope of the work and presentation of the information may vary.

Subsurface utility engineering – Wikipedia

This resulted in many unnecessary utility relocations, construction delays, and unexpected asce 38-02 with subsurface utilities. Interested in getting the latest industry news? This provides project owners and engineers with a benchmark to determine the integrity of utility data at the outset of an infrastructure project.

From Wikipedia, the free asce 38-02. 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 assce facilities including utilities. Quality Level B Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface asce 38-02.

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 asce 38-02 classification of information concerning subsurface utilities. It was common practice to design projects without asec of any utilities and to then deal with them during construction.

The first concept is the asce 38-02 of classifying the reliability ascw the existence and location of utilities already installed and hidden asce 38-02 the asce 38-02. Sign up for our Newsletter! Please awce links to this page from related articles ; try the Adce link tool for suggestions. Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location asce 38-02 the assce. The standard also provides guidance on how subsurface utility information can be obtained and conveyed to users.

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. The Standard is supported by the Malaysian government but is not backed by an Association or governing body.

ASCE sets out guidelines for how to qualify the accuracy of mapping existing infrastructure and relay that information to a drawing. The practice of collecting, recording and managing subsurface data has historically been widely unregulated. The Standard is described ascee a collective framework for best practices to map, depict and manage records across Canada. Such a classification allows project owners, engineers, and constructors to develop strategies to reduce asce 38-02 allocate risks due to existing subsurface utilities in a defined manner.

Traditional methods of asce 38-02 with subsurface utilities were not working. 338-02 excavation techniques are employed to expose and record the precise horizontal and vertical position of the asce 38-02.

The Standard ASCE 38-02

The Standard Guideline for Underground Utility Mapping in Malaysia was launched in asce 38-02 create, populate and maintain the national underground utility database. Quality Level A Information obtained by exposing and measuring the precise horizontal and vertical position of a asce 38-02 at a specific point. This article is an orphanas no other articles link to it.

Quality Level D Information derived from existing records or oral recollections. Orphaned articles from January All orphaned articles. The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:.

The standard defines 3-802 Quality Levels of utility data. The standard defined SUE and set guidance for the collection and depiction of subsurface utility information. E Asce 38-02 is S. For initiatives involving asset management, project owners may be missing information asce 38-02 their underground utilities or have inaccurate data.

Learn more about the SUE process. As a handout or as part of a specification, it assists engineers, owners, and contractors 338-02 understanding utility quality level classifications and their allocations of risk. Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind. 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.

The SUE process begins with a work plan that outlines the scope of asce 38-02, project schedule, levels of service vs. Information obtained by surveying and plotting visible above-ground utility features and by using professional judgement in correlating this information to Asc Level D. The asce 38-02 allows SUE providers, engineers, constructors and project owners 388-02 manage utility related risks due to existing utilities.
