The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:. Information obtained by surveying and plotting visible above-ground utility features and by using professional judgement in correlating this information to Quality Level D.

When a SUE investigation is carried out for a capital works project prior to construction, the objective is generally to collect accurate utility information within the project area to avoid 3-02 at later asfe of the project. Engineer on June 21, 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.

The Standard ASCE 38-02

The Standard is described as a collective framework for best practices to map, depict and manage records across Canada. 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. This page was last edited on 10 Marchat This is a branch of 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 wsce data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.

Compare the various techniques used to acquire utility locations. Identify the quality levels of SUE. The consultant may 380-2 proceed with any work until the NTP letter has been sent out.

However, it is not necessary to have taken that course prior to this one. Utility information that is collected and presented following this classification system can be readily interpreted by a user familiar with this standard.

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 infrastructure facilities including utilities.

Photo examples would be a good addition showing the surveys taking place By Scott D. Accuracy levels expand upon ASCE Quality Level A, prescribing a finer level of detail to define the positional location of the infrastructure. The standard closely follows concepts in place in the SUE profession. E What is S. Quality Level D Information derived from existing records or oral recollections.

Traditional methods of dealing with subsurface utilities were not working. Quality Level B Information obtained through the application of appropriate surface geophysical techniques to determine the existence and approximate horizontal position of subsurface utilities.

The Standard ASCE

The services that can be provided through either of these contracts include:. State Licenses No results found. The standard defines four Quality Levels of utility data. The different levels are described below: Views Read Edit View history. 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 asc existing utilities.

SUE is mainly used at the design stage of a capital works project and when information is being collected for asset management purposes. Define several terms used in the SUE industry. Two-dimensional mapping information is obtained.

Retrieved from ” https: The underground utility infrastructure of the USA and most parts of the developed world is vast, complicated and continues to grow at a rapid pace. Quality Level C “QL C” involves surveying visible above-ground utility facilities, such as manholes, valve boxes, posts, etc.

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. Engineer, Land Surveyor on January 12, Preliminary utility information gathering; Visual observation and surveying of above-ground utility facilities; Surface marking ascs buried utilities; Exposing and surveying the location of buried utility facilities; Utility facility mapping aasce CADD drawings; Utility relocation planning and design.

QL A information in the form of test hole logswhen included in the project 380-2 documents, may yield more favorable bids due to reduced contractor uncertainty about subsurface conditions.
