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).

Slope Stability 2 hours. This Standard establishes procedures for the mapping of utilities for the purposes of reducing the uncertainties created by existing underground utilities.
Subsurface Utility Engineering – Part 2: Understanding CI/ASCE
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 In both situations, a similar process is followed but the scope of the work and presentation of the information may vary. The first concept is the means of classifying the reliability of the existence and location of utilities already installed and hidden in the ground.
Therefore, its usefulness may be limited to preliminary design reviews or to projects with minimal anticipated conflicts.
The SUE process begins with a work plan that outlines the scope of work, project schedule, levels of service vs. Accuracy levels expand upon ASCE Quality Level A, prescribing a finer asfe of detail to define the positional location of the infrastructure. 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 38–02, and utility design.
When ascee 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 conflict at later stages of the project. Define several terms used in the SUE industry. Once such approval is obtained, the Agreements Office will coordinate issuance of the Notice to Proceed letter with the Region.
It is used primarily during utility installation. Engineer, Land Surveyor on January 12, Should be a video presentation. For initiatives involving asset management, project owners may be missing information about their underground utilities or have inaccurate data.
This ase is an orphanas no other articles link to it. It is not appropriate to contact both consultants with the intention of soliciting competing cost estimates.
The Standard ASCE 38-02
This provides project owners and engineers with a benchmark to determine the integrity of utility data at the outset of an infrastructure project. 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.
Click on the state to expand the license or professional organization that applies to the course. To order a copy of the standard from the ASCE website, please click here. Quality Level A “QL A ” involves the use of nondestructive digging equipment at asde, critical points to determine the precise horizontal and vertical position of underground utilities, as well as the type, size, condition, material, and other characteristics.
Engineer, Land Surveyor on January 12, Slight adjustments in the design asve produce substantial cost savings by eliminating utility relocations. 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. Quality Level D Information derived from existing records or oral recollections. The different levels are described below: Explain the responsibility of the project owner, engineer, subsurface utility engineer and utility owner relative to existing utilities on construction projects.
Subsurface Utility Engineering – Part 2: Understanding CI/ASCE 38-02
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.
This activity is called “locating. Civil engineering Geotechnical engineering. Compare the various techniques used to acquire utility locations. Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point.
This ASCE standard presents a system to classify the quality of existing subsurface utility data. In June,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 of information concerning subsurface utilities.
It is fundamentally a traditional survey and documentation function. 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.
