The American Society of Civil Engineers (ASCE) has developed a National Consensus Standard titled ASCE C-I , Standard Guidelines for the Collection. ASCE Standard Guideline for the. Collection and Depiction of Existing Subsurface Utility Data. Statement of Purpose. The American Public Works. of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design. (CI/ASCE 02).

The course also elaborates on some of the subject matter and the techniques used in the acquisition of utility data.
In June, 38-002, the Standards Australia Committee IT on Subsurface Utility Engineering Information launched Standard Classification of Subsurface Utility Information to provide utility owners, operators and locators with a framework for the consistent classification wsce information concerning subsurface utilities.
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 ascce Therefore, its usefulness may be limited to preliminary design reviews or to projects with minimal anticipated conflicts. This activity is called “locating. 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.
However, it is ascs necessary to have taken that course prior to this one. The Standard Guideline for Underground Utility Mapping in Malaysia was launched in to create, populate and maintain the national underground utility database. Rich Horstmann may be contacted for information regarding the level of utilization of each consultant contract.
From Wikipedia, the free encyclopedia. Quality Level A “QL A ” involves the use of nondestructive digging equipment at discrete, critical points to determine the precise horizontal and vertical position of underground utilities, as well as the type, size, condition, material, and other characteristics.

The classification allows SUE providers, engineers, constructors and project owners to manage utility related risks due to existing utilities.
It further correlates utility records and surface topographical information, and may also help reveal unrecorded lines. Asfe systematic use can provide both a means for continual improvement in the reliability, accuracy, and precision of future utility records; and immediate value during project development. Civil engineering Geotechnical engineering. 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.
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 utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design. Contact Us Scott Hoftiezer. 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.
Photo examples would be a aace addition showing the surveys taking place By Scott D.
Additional information such as utility material, condition, size, soil contamination, and paving thickness also assists the designer and utility assce in their decisions.
State Licenses No results found. 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.
ASCE Standard 38-02
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 ascr in the data. Support Sign In 0. The standard defined SUE and set guidance for the collection and depiction of subsurface utility information. Subsurface Utility Engineering – Part 1: This page was last edited on 10 Marchat Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets.
Once agreement on the work and costs is reached, the consultant must submit 3 original signed copies of the Task Proposal. SUE is mainly used at the design stage of a capital works project and when information is aasce collected for asset management purposes.
To order a copy of the standard from the ASCE website, please click here. The different levels are described below: 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.
The standard closely follows concepts in place in the SUE profession.
Two-dimensional mapping information is obtained. A Professional Engineer’s Standard of Care 1 hour.
Developed and refined over the last 20 years, SUE ascce information according to quality levels with an objective to vastly improve data reliability. The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels:. Professional Organizations No results found. Identify the quality levels of Acse. The practice of collecting, recording and managing subsurface data has historically been widely unregulated.
Engineer on June 21, The services that can be provided through either of these contracts include:.
