Contract Scope of Services

Subsurface Utility Engineering (SUE) – An engineering practice that involves mapping utilities at appropriate quality levels (D, C, B, A) and communication of utility data to concerned parties. Shall meet American Society of Civil Engineers (ASCE) standard 38-22 or more recent standard at the time of the project.

1.1.1. Deliverables:

• CAD Drawing

• PDF Version- with Professional Certification required for QL-A & QL-B investigations

Comprehensive presentation of investigation mapping, notes, research, methodology

• Coordinate List

• Field Book Copies & Sketches

• Photographs

• Trench or Test Hole Data Sheets, documenting utilities uncovered in QL-A and/or trenching efforts

Other deliverables to be determined per project SOW. Professionals must be mindful of their specific competencies, limitations, and expertise in performing specific functions. For projects involving excavation, proper compaction of the backfill is required. Powered tampers should be used at a minimum for every 6-in. lift of backfill placed. For test holes involving electric facilities encased in thermal sand, the SUE provider must demonstrate knowledge and ability to safely excavate, observe, and properly repair the encasement.

Professional will be responsible for proper spoil disposal, site remediation and environmental controls.

Professional is encouraged to highlight any possible Advanced Geophysical capabilities beyond typical utility location services, examples being Geotechnical, Environmental, and

Constructability Interpretation services. The potential advantages of these techniques include higher data density, data interpretation software, and concurrent ground control.

Interpretations beyond the existence and position of utilities include the possibilities for paving thickness, substrate thickness, voids, depth-to-water tables, depth to bedrock, debris or boulders, gravesites, septic fields, tanks, drums, wells, contamination plumes, and more.
