It is not appropriate to contact both consultants with the intention of soliciting competing cost estimates. 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 C “QL C” involves surveying visible above-ground utility facilities, such as manholes, valve boxes, posts, etc.
Ten Tips for Green Building Certification 1 hour.
Three copies of each of the following: 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. Identify the quality levels of SUE. Professional Organizations No results found. This article is an orphanas no other articles link to it.

Thanks By zaki W. Sign up for our Newsletter! Information obtained by exposing and measuring the precise horizontal and vertical position of a utility at a specific point.

The appropriate use of SUE services can prevent these problems. Click on the Quality Levels tab above for definitions. Subsurface Utility Engineering – Part 1: Engineer on December 27, very detailed Thanks By zaki W. With this massive web of active and abandoned underground utility systems in place, all new excavations are at risk of encountering unplanned utility conflicts and causing potential damage. Developed and refined over the last 20 years, SUE classifies information according to quality levels with an objective to vastly improve data reliability.
Explain the ace of the project owner, engineer, subsurface utility engineer and utility owner relative to existing utilities on construction projects. Combining these concepts will lead to a continual reduction in the risks created by underground utilities during future projects involving excavation of any kind.
Engineer, Land Surveyor on January 12, Should be a video presentation.

Home About Us About S. It may provide an overall “feel” for the congestion of utilities, but it is often highly limited in terms of comprehensiveness and accuracy. QL C information may not, however, eliminate all inaccuracies; nor will it reveal an unrecorded line awce has no surface features.
ASCE Standard 38-02
The consultant may not proceed with any work until the NTP letter has been sent out. Should be a video presentation. The services that can be provided through either of these contracts include:. Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets.
In both situations, a similar process is followed but the scope of the work and presentation of the information may vary. The different levels are described below: 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.
Singer is also an instrument rated pilot. Slight adjustments in the design may produce substantial cost savings by eliminating utility relocations. Orphaned articles from January All orphaned articles.
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. The classification allows SUE providers, engineers, constructors and project owners to manage utility related risks due to existing utilities.
