We understand that New construction, repairs or remediation often conflict with existing infrastructure. The cost of conflict resolution and the potential for catastrophic damage and incident are highest during these projects. Having inaccurate, incomplete, outdated information on existing utilities reduces the engineers, owners and contractor’s ability to make informed decisions and to support the risk management decisions regarding the project’s impact on existing utilities. SUE establishes a credible nomenclature system to fix attributes to utility information to denote quality of utility information. The intent is to reduce risk by improving the reliability of information on existing subsurface utilities in a defined manner as described by ASCE Standard 38-02.
BullseyeSUBSURFACE UTILITY ENEGINEERING (SUE) service is used at the design stage of a project and when information is being collected for asset management and maintenance purposes. In both situations, a similar process is followed based on the needs of the project and location challenges. The scope of the work and deliverable of the information may vary. When a SUBSURFACE UTILITY ENEGINEERING (SUE) investigation is conducted prior to construction, the objective is generally to collect accurate utility information within the project area to avoid conflicts and increased cost, such as utility damage, unplanned utility relocation and accidents at later stages of the project.
For asset management and maintenance, project owners may be missing information about their underground utilities or have inaccurate data. In this situation a Bullseye (SUE) team would collect the required information and add it to the asset management database, according to the four quality levels prescribed by ASCE Standard 38-02.
SUBSURFACE UTILITY ENEGINEERING (SUE) Quality Levels
Quality Level D is the most basic level of information for utility locations. It comes from collecting existing utility records or verbal recollections. QUALITY LEVEL-D is useful primarily for project planning and route selection activities.
Quality Level C involves surveying visible above ground utility facilities (e.g., manholes, valve boxes, etc.) and correlating this information with existing utility records (QUALITY LEVEL-D information).
Quality Level B involves the application of appropriate surface geophysical methods such as EM-Electromagnetic and GPR Ground Penetratingto determine the existence and horizontal position of virtually all subsurface utilities within a project’s limits.
Quality Level A Is the highest level of accuracy presently available. It provides information for the precise plan and profile mapping of underground utilities through the actual exposure of underground utilities AKA “daylighting”, (usually at a specific point), and provides the type, size, condition, material and other characteristics of underground features. Exposure is typically achieved through hand digging or Vacuum excavation
BullseyeSUBSURFACE UTILITY ENEGINEERING (SUE) Services
SUBSURFACE UTILITY ENEGINEERING (SUE) is a proven solution to solve the problems and rick associated with working on or around underground utilities. It is Bullseye’s goal to provide its clients the best possible information in order to reduce or eliminate project delays, damage to utilities, to promote the safety of workers & the public, redesign costs, change orders and bad publicity. This process reduces risk and to allow a controlled flow for construction and utility infrastructure projects. Our clients are able to Save Time, Money and produce a better product.
