General A. Definitions and Terms. 1. CI/ASCE 38-02: “Standard Guideline for the Collec- tion and Depiction of Existing Subsurface Utility Data,” American Society of Civil Engineers, 2003. 2. DOT: State Department of Transportation and/or its authorized representative(s), as the context implies. 3. Consultant: The individual or firm directly, or indirectly through sub-consultants, providing engineering and design-related services as a party to the contract. 4. Contract Manager: The designated DOT representative responsible to coordinate, authorize, and monitor the status of task orders issued pursuant to the contract. 5. Project Manager: The designated DOT representative, typically from the involved DOT region, responsible on a specific project to evaluate and prescribe SUE needs, and to monitor the performance of approved tasks. 6. R.S.: Revised Statutes, as amended [Replace this ref- erence with the name of applicable State statute]. 7. MUTCD: “Manual on Uniform Traffic Control Devices,” U.S. Department of Transportation, Millennium Edition, December 2000. 8. QL A: Utility Quality Level A as further described herein. Generally, QL A indicates the precise horizontal and ver- tical location of utilities obtained by the actual exposure (or verification of previously exposed and surveyed utili- ties) and subsequent measurement of subsurface utilities, usually at a specific point. 9. QL B: Utility Quality Level B as further described herein. Generally, QL B indicates information obtained through the application of appropriate surface geophysi- cal methods to determine the existence and approximate horizontal position of subsurface utilities. 10. QL C: Utility Quality Level C as further described herein. Generally, QL C indicates information obtained by sur- veying and plotting visible above-ground utility features and by using professional judgment in correlating such information to QL D information. 11. QL D: Utility Quality Level D as further described herein. Generally, QL D indicates information derived from existing records and oral recollections. 12. Subsurface Utility Engineering, or SUE: 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, util- ity relocation cost estimates, implementation of utility accommodation policies, and utility design. aPPendix d Sue Sample Scope of Work 13. UNC: Utility Notification Center. 14. Utility Quality Level: A professional opinion of the quality and reliability of utility information. Such reli- ability is determined by the means and methods of the professional. B. Work Locations. 1. Potential projects on which SUE may be required are at undetermined locations statewide.

When available, verifiable information on previously exposed and surveyed utilities (such as survey records during utility line construction) shall be furnished in lieu of new excavation, exposure, and survey at that same point, or at a suitable nearby point. 2. Otherwise, when utility lines must be exposed and sur- veyed at specified locations, the Consultant shall use mini- mally intrusive excavation techniques, acceptable to DOT, that ensure the safety of the excavation, the integrity of the utility line to be measured, and that of other lines which may be encountered during excavation. 3. DOT intends that excavation shall be by means of air- or water-assisted vacuum excavation equipment manufactured specifically for the purpose, provided, however, that approval of water-assisted vacuum excavation may be subject to addi- tional findings by DOT that such method poses minimal risk of damage to the highway facility or utility lines.

Avoid damage to lines, wrappings, coatings, cathodic protection, or other protective coverings and features. 6. Hand-dig as needed to supplement mechanical excava- tion and to ensure safety. 7. Revise the test hole location as necessary to positively expose the utility. 8. Store excavated material for re-use or disposal, as appropriate. F. Collection, Recording, and Presentation of Data. Measure and/or record the following information on an appro- priately formatted test hole data sheet that has been sealed and dated by the Consultant: 1. Elevation of top and/or bottom of the utility tied to the project datum, to a vertical accuracy of ±0.05 feet (15 mm). 2. Elevation of existing grade over utility at test hole. 3. Horizontal location referenced to project coordinate datum, to a horizontal accuracy consistent with appli- cable DOT survey standards. 4.

As applicable, provide permanent pavement restoration within the limits of the original cut using materials, com- paction, and pavement thickness acceptable to DOT. 5. Repair or replace backfill or pavement that fails (i.e., subsid- ence and/or loss of pavement material) within two (2) years of the original restoration work. 6. For excavations in unpaved areas, restore disturbed area as nearly as practicable to pre-existing conditions. 7. Furnish and install permanent surface marker (e.g., P.K. nail, peg, steel pin, or hub) directly above the centerline of the structure and record the elevation of the marker. Interpretation of Data and Resolution of Discrepancies. 1. Exercise professional judgment to correlate data from dif- ferent sources, and to resolve conflicting information. 2.
