Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. When using this information, it is not unusual to find underground utilities that have been either omitted or erroneously plotted.
The standard defines four Quality Levels of utility data. This activity is called “designating”. This information, when combined with other surveyed and mapped information, allows the designer to infer plan and profile information, for use in axce final design decisions. Quality Level B “QL B” involves the use of surface geophysical techniques to determine the existence and horizontal position of underground utilities.
Once such approval is obtained, the Agreements Office will coordinate issuance of the Notice to Proceed letter with the Region. This information may be sufficient to accomplish preliminary engineering goals, by helping the designer to determine where to place storm drainage systems, footers, foundations, and other design features in order to avoid conflicts with existing utilities.
Preliminary utility information ssce Visual observation and surveying of above-ground utility facilities; Surface marking of buried utilities; Exposing and surveying the location of buried utility facilities; Utility facility mapping and CADD drawings; Utility relocation planning and design. Xsce different levels are described below:. Should be a video presentation. It further correlates utility records and surface topographical information, and may also help reveal unrecorded lines.
Support Sign In 0. Quality Level B Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. Its usefulness may be limited to early design stage project planning and route selection activities or to projects with minimal planned excavations.
The Acse standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:. Click on the state to expand the license or professional organization that applies to the course. Orphaned articles from January All orphaned articles. Singer has worked as a subsurface utility engineer or a utility relocations design engineer. Click on the Quality Levels tab above for definitions.
ASCE Standard 38-02
ASCE sets out guidelines for how to qualify 83-02 accuracy of mapping existing infrastructure and relay that information to a drawing. Thanks By zaki W. The consultant may not proceed with any work until the NTP letter has been sent out. This ASCE standard presents a system to classify the quality of existing subsurface utility data.
The Standard ASCE
Learn more about the SUE process. As a handout or as part of a specification, it assists engineers, owners, and contractors in understanding utility quality level classifications and their allocations of risk.
Therefore, its usefulness may be limited to preliminary design reviews or to projects with minimal anticipated conflicts. Contact Us Scott Hoftiezer. Traditional methods of dealing with subsurface utilities ascw not working.
PAS applies to the detection, verification and location of active, abandoned, redundant or unknown underground utilities and associated surface features that facilitate the location and identification of underground utility infrastructure.
Subsurface Utility Engineering – Part 2: Understanding CI/ASCE
It sets out the accuracy to which the data is captured for specific purposes, the quality expected of that data and a means by which to assess and indicate the confidence that can be placed in the data.
Compare the various techniques used to acquire utility ascw. Sign up for our Newsletter! Civil engineering Geotechnical engineering. Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind. Professional Organizations No results found. Interested in getting the latest industry news?
Singer currently owns and operates Singer Utility Engineering, P. Additional information such as utility material, condition, size, soil contamination, and paving thickness also assists the designer and utility owner in their decisions.
It is used primarily during utility installation.
Quality Level D Information derived from existing records or oral recollections. State license renewal information is provided as a convenience ascf and is xsce to change at any time. Photo examples would be a good addition showing the surveys taking place By Scott D. From Wikipedia, the free encyclopedia. Define several terms used in the SUE industry. Rich Horstmann may be contacted for information regarding the level of utilization of each consultant contract.
The Standard Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database. Utility information ase is collected and presented following this classification system can axce readily interpreted by a user familiar with this standard. Once agreement on the work and costs is reached, the consultant must submit 3 original signed copies of the Task Proposal.
Subsurface Utility Engineering – Part 2: 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. This page was last edited on 10 March acse, at With this massive web of active and abandoned underground utility systems in place, all new excavations are at risk of encountering unplanned utility conflicts and causing potential damage.
The standard defined SUE and set guidance for the collection and depiction of subsurface utility information.
