ASCE Standard 38-02

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. The standard closely follows concepts in place in the SUE profession.

This activity is called “locating. By knowing exactly where a utility is positioned in three dimensions, the designer can accurately determine the extent of a utility conflict, or can often make small adjustments in elevations or horizontal locations and avoid the need to relocate utilities. 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. The course also elaborates on some of the subject matter and the techniques used in the acquisition of utility data.

Photo examples would be a good addition showing the surveys taking place By Scott D. Once agreement on the work and costs is reached, the consultant must submit 3 original signed copies of the Task Proposal. The concept of SUE is gaining popularity worldwide as a framework to mitigate costs associated with project redesign and construction delays and to avoid risk and liability that can result from damaged underground utilities.


Rich Horstmann may be contacted for information regarding the level of utilization of each consultant contract. From Wikipedia, the free encyclopedia. Retrieved from ” https: This resulted in many unnecessary utility relocations, construction delays, and unexpected encounters with subsurface utilities.

Recognize the original individuals involved in the development of SUE. Define several terms used in the SUE industry. Home About Us About S. Engineer, Land Surveyor on January 12, Explain the responsibility of the project owner, engineer, subsurface utility engineer and utility owner relative to existing utilities on construction projects.

The SUE process begins with a work plan that outlines the scope of work, project schedule, levels of service ace. Traditional methods of dealing with subsurface utilities were not working. Singer has worked as a subsurface utility engineer or a utility relocations design engineer. 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.

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 asxe development. This page was last edited on 10 Marchat Contact Us Scott Hoftiezer.

It is used primarily during utility installation. ASCE sets out guidelines for how to qualify the accuracy of asde existing infrastructure and relay that information to a drawing. Quality Level D Information derived from existing records or oral recollections.

Thanks By zaki W. The classification allows SUE providers, engineers, constructors and project owners to manage utility related risks due to existing utilities. Three copies of each of the following: Its usefulness may be limited to early design stage project planning and route selection activities or to projects with minimal planned excavations.

Subsurface Utility Engineering – Part 2: Understanding CI/ASCE 38-02

The standard also provides guidance on how subsurface utility information can be obtained and conveyed to users. However, it is not necessary to have taken that course prior to this one. Quality Level C “QL C” involves surveying visible above-ground utility facilities, such as manholes, valve boxes, posts, etc.


State license renewal information is provided as a convenience only and is subject ascce change at any time. Views Read Edit View history. Information obtained by surveying and plotting visible above-ground utility features and by using professional judgement in correlating this information to Quality Level D.

The standard defined SUE and set guidance for the 38-2 and depiction of subsurface utility information. Engineer on June 21, Slope Stability 2 hours. Therefore, its usefulness may be limited to preliminary design reviews or to projects with minimal anticipated conflicts. The course begins by discussing the history behind the development of the Standard. This information, when combined with other surveyed and mapped information, allows the designer to infer plan and profile information, for use in making final design decisions.

Terms and Conditions Privacy Policy iaa4faad5a5cc. This provides project owners and engineers with a benchmark to determine the integrity of utility data at the outset of an infrastructure project. Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. Evaluate the cost savings realized by using SUE.

Many countries followed the U. Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location of the infrastructure. Click on the Quality Levels tab above for definitions.

The consultant may not proceed with any work until the NTP letter has been sent out. Quality Awce A Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point.
