Its usefulness may be limited to early design stage project planning and route selection activities or to projects with minimal planned excavations.

From Wikipedia, the free encyclopedia. The Standard is supported by the Malaysian government but is not backed by an Association or governing body. Explain the responsibility of the project owner, engineer, subsurface utility engineer and utility owner relative to existing utilities on construction projects.

Views Read Edit View history.

By knowing exactly 38-2 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. When using this information, it is not unusual to find underground utilities that have been either omitted or erroneously plotted.

Committed to Damage Prevention This resulted in many unnecessary utility relocations, construction delays, and unexpected encounters with subsurface utilities. Contact Us Scott Hoftiezer.

Subsurface utility engineering – Wikipedia

However, it is not necessary to have taken that course prior to this one. No formal procedure has been established for CDOT personnel to follow in selecting one consultant versus the other for a particular project, but over the term of the two NPS contracts 2 yearsapproximately equal utilization of each firm is desirable.

Subsurface Utility Engineering – Part 2: The different levels are described below: 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. State license renewal information is provided as a convenience only and is subject to change at any time. QL C information may not, however, eliminate all inaccuracies; nor will it reveal an unrecorded line that has no surface features.

Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location of the infrastructure. Engineer on December 27, Once agreement on the work and costs is reached, the consultant must submit 3 original signed copies of the Task Proposal.

Video works better than text. Three copies of each of the following: Two-dimensional mapping information is obtained. Engineer, Land Surveyor on January 12, Quality Level C 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 A Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point.

The Standard ASCE 38-02

The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:. Once such approval is obtained, the Agreements Office will coordinate issuance of the Notice to Proceed letter with the Region. Back to Search Results.

Engineer on December 27, very detailed Thanks By zaki W. Additional information such as utility material, condition, size, soil contamination, and paving thickness also assists the designer and utility owner in their decisions. Identify the quality levels of SUE. Terms and Conditions Privacy Policy iaa4faad5a5cc.

ASCE Standard 38-02

This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground utilities. The SUE process begins with a work plan that outlines the scope of work, project schedule, levels of service vs.

Recognize the original individuals involved in the development of SUE. Singer has worked as a subsurface utility engineer or a utility relocations design engineer.

Quality Level B Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities. QL A information in the form of test hole logswhen included in the project bid documents, may yield more ascee bids due to reduced contractor uncertainty about subsurface conditions. Singer currently owns and operates Singer Utility Engineering, P.

The practice of collecting, recording and managing subsurface data has historically been widely unregulated. The consultant may not proceed with any work until the NTP letter has been sent out.

S.U.E. Subsurface Utility Engineering —

This provides project owners and engineers with a benchmark to determine the integrity of utility data at the outset of an infrastructure project. Ten Tips for Green Building Certification 1 hour. Compare the various techniques used to acquire utility locations. Singer is also an instrument rated asxe. The standard also provides guidance on how subsurface utility information can be obtained and conveyed to users.

The Standard is described ascce a collective framework for best practices to map, depict and manage records across Canada.
