Common use of SUBSURFACE UTILITY ENGINEERING Clause in Contracts

SUBSURFACE UTILITY ENGINEERING. Utility Engineering Investigation (currently Subsurface Utility Engineering) shall include utility investigations subsurface and above ground prepared in accordance with AASHTO standards [ASCE C-1 38-02 ▇▇▇▇://▇▇▇.▇▇▇▇.▇▇▇.▇▇▇/programadmin/asce.cfm)] and Utility Quality Levels. Utility Quality Levels are defined in cumulative order (least to greatest) as follows: Quality Level D - Existing Records: Utilities are plotted from review of available existing records. Quality Level C - Surface Visible Feature Survey: Quality level "D" information from existing records is correlated with surveyed surface- visible features. Includes Quality Level D information. If there are variances in the designated work area of Level D then a new schematic or plan layout, if needed, is required showing the limits of the proposed project and limits of the work area required for this work authorization; including highway stations, limits within existing or proposed right of way, additional areas outside the proposed right of way, and distances or areas to be included down existing intersecting roadways. If there are variances in the designated work area of Level D then a new schematic or plan layout, if needed, is required showing the limits of the proposed project and limits of the work area required for this work authorization; including highway stations, limits within existing or proposed right of way, additional areas outside the proposed right of way, and distances or areas to be included down existing intersecting roadways. Quality Level B - Designate: Two-dimensional horizontal mapping. This information is obtained through the application and interpretation of appropriate non-destructive surface geophysical methods. Utility indications are referenced to established survey control. Incorporates quality levels C and D information to produce Quality Level B. If there are variances in the designated work area of Level D then a new schematic or plan layout, if needed, is required showing the limits of the proposed project and limits of the work area required for this work authorization; including highway stations, limits within existing or proposed right of way, additional areas outside the proposed right of way, and distances or areas to be included down existing intersecting roadways. If there are variances in the designated work area of Level D then a new schematic or plan layout, if needed, is required showing the limits of the proposed project and limits of the work area required for this work authorization; including highway stations, limits within existing or proposed right of way, additional areas outside the proposed right of way, and distances or areas to be included down existing intersecting roadways. DocuSign Envelope ID: F43CDC74-DA27-4A02-AC2A-90D8CB2811D6 Quality Level A - Locate (Test Hole): Three-dimensional mapping and other characterization data. This information is obtained through exposing utility facilities through test holes and measuring and recording (to appropriate survey control) utility/environment data. Incorporates quality levels B, C and D information to produce Quality Level A. For schematic design, the Engineer shall perform Designate Quality Level B. For PS&E, the Engineer shall perform Quality Level A to further locate utility conflicts identified during the schematic design. Designate (Quality Level B) Designate means to indicate the horizontal location of underground utilities by the application and interpretation of appropriate non-destructive surface geophysical techniques and reference to established survey control. Designate (Quality Level B) Services are inclusive of Quality levels C and D. The Engineer shall:
