The Standard Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database. Photo examples would be a good addition showing the surveys taking place By Scott D.
ASCE Standard 38-02
It further correlates utility records and surface topographical information, and may also help reveal unrecorded lines. 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 cost estimates, implementation of utility accommodation policies, and utility design.
This article is an orphanxsce no other articles link to it. Engineer, Land Surveyor on January 12, 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 by ASCE Standard Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets.
State Licenses No results found. This provides project owners and engineers with adce benchmark to determine the integrity of utility data at the outset of an infrastructure project.
The first concept is the means of classifying the reliability of the existence and location of utilities already installed and hidden in the ground. Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point.
The standard defines four Quality Levels of utility data. It was common practice to ascee projects without consideration of any utilities and to then deal with them during construction.

QL A information in the form of test hole logswhen included in the project bid documents, may yield more favorable bids due to reduced contractor uncertainty about subsurface conditions.
Slope Stability 2 hours. The Standard is described as a collective framework for best practices to map, depict and manage records across Canada. In choosing which consultant to use, factors such as specific consultant capabilities, and the ability of the consultant to meet desired timeframes for commencing and completing the SUE work may be considered.

Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location of the infrastructure. Developed and refined over the last 20 years, SUE classifies information according to quality levels with an objective to vastly improve data reliability. Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind.
Engineer on December 27, very detailed Thanks By zaki W. Xsce, Land Surveyor on January 12, Should be a video presentation. Therefore, its usefulness may be limited to preliminary design reviews or to projects with minimal anticipated conflicts.
The different levels are described below:. Support Sign In 0.
The course begins by discussing the history behind the development of the Standard. It may provide an overall “feel” for the congestion of utilities, but it is often highly limited in terms of comprehensiveness and accuracy.
A/I/DATA – Standards
Explain the responsibility of the project owner, engineer, subsurface utility engineer and utility owner relative to existing utilities on construction projects. It is the ultimate responsibility of the individual to be sure that he or she is meeting continuing education requirements for each license and corresponding renewal period.
Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. Ten Tips for Green Building Certification 1 hour. This is a branch 83-02 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, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.
SUE began in the early s.
