SUBSURFACE UTILITY ENGINEERING. Subsurface Utility Engineering services includes utility investigations subsurface and above ground prepared in accordance with AASHTO standards and Utility Quality Levels as defined in the Utilities Section of the Design Criteria Manual. Based on the review of existing utilities and proposed roadway design, bridge design, drainage design, and other potential conflicts for utilities, the Utility Coordinator will recommend required test holes after completion of 60% conflict assessment. The Utility Coordinator will coordinate with the appropriate Utility Owner to utilize internal work forces toperformrequiredtestholesfor verification of its facilities. If requested, the Utility Coordinator will coordinate with the County and/or its Designated Representative to provide the required test holes. A sketch of the area to be included for the proposed test hole locations “Level A” will be provided prior to the start of the work and must be approved by the County and/or its Designated Representative. The County or its Designated Representative will provide comments or approval of test hole plan within five (5) business days. 4.1. Subsurface Utility Designate Service (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 Utility Coordinator shall: 4.1.1. As requested by the County, compile "As Built" information from plans, plats and other location data as provided by the utility owners. 4.1.2. Coordinate with utility owner when utility owner's policy is to designate their own facilities at no cost for preliminary survey purposes. The Utility Coordinator will examine utility owner's work toensure accuracy and completeness. 4.1.3. Designate, record and mark the horizontal location of the existing utility facilities and their service laterals to existing buildings using non-destructive surface geophysical techniques.

SUBSURFACE UTILITY ENGINEERING. Subsurface Utility Engineering includes utility investigations subsurface and above ground prepared in accordance with AASHTO standards ASCE/CI 38-22 [(xxxx://xxx.xxxx.xxx.xxx/programadmin/asce.cfm)] and Utility Quality Levels. A. 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. It is assumed that 18,500 LF of QL B designates will be required: 7,000 LF FM 2759 9,500 LF Along neighborhood 2,000 LF Along Sienna Ranch Rd The Utility Engineer must: Designate, record, and mark the horizontal location of the existing utility facilities using non- destructive surface geophysical techniques. Using both active and passive scans to attempt to locate any additional utilities, including unrecorded and abandoned storm and sanitary sewer facilities, at the direction of the County, may be investigated using additional methods such as rodding that would then classify them as Quality Level B. Correlate utility owner records with designating data and resolve discrepancies using professional judgment. The Utility Engineer must prepare and deliver to the County a color-coded composite utility facility plan with utility owner names, quality levels, line sizes and subsurface utility locate (test hole) locations. The Utility Engineer and County acknowledge that the line sizes of designated utility facilities detailed on the deliverable will be from the best available records and that an actual line size is normally determined from a test hole vacuum excavation. A note must be placed on the designate deliverable only that states "lines sizes are from best available records". All above-ground utility feature locations must be included in the deliverable to the County. Clearly identify all utilities that were discovered from Quality Levels C and D investigation but cannot be depicted in Quality Level B standards. These utilities must have a unique line style and symbology in the designate (Quality Level B) deliverable. B. Locate via Test Holes (Quality Level A) Locate is the process used 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 excava...
