• 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 the Project; 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 the Project; 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. 1.3.3 Provide up to ten (10) Subsurface Utility (Test Hole) Locates (Quality Level A), to obtain precise horizontal and vertical position, material type, condition, size and other data that may be obtainable about the utility facility and its surrounding environment through exposure by non- destructive excavation techniques that ensures the integrity of the utility facility. Measure and record the following data, as required, on an appropriately formatted test hole data sheet that has been sealed and dated by the Engineer: • Elevation of top and/or bottom of utility tied to the datum of the furnished plan. • Identify a minimum of two benchmarks utilized. Elevations shall be within an accuracy of 0.05 feet of utilized benchmarks. • Elevation of existing grade over utility at test hole location. • Horizontal location referenced to project coordinate datum. • Outside diameter of pipe or width of duct banks and configuration of nonencased multi- conduit systems. • Utility facility material(s) and condition • Pavement thickness and type. • Coating /wrapping information and condition. • Unusual circumstances or field conditions. • Excavate test holes in such a manner as to prevent any damage to wrappings, coatings, cathodic protection or other protective coverings and features. • Backfill all excavations with appropriate material, compact backfill by mechanical means, and restore pavement and surface material. • Furnish and install a permanent above - ground marker directly above center line of the utility facility. 1.3.4 Plot utility location position information to scale and provide a comprehensive utility Kimley -Horn — FM 2439 (Hunter Road) 5
