A joint use audit is the systematic field verification of every third-party attachment on a utility’s poles — documenting who is attached, what their equipment is, whether it meets NESC clearance requirements and FCC Part 1 telecommunications rules, and how the field reality compares to billing records. For electric utilities, rural cooperatives, and municipal power systems, pole attachments from cable operators, telecom companies, fiber providers, and wireless carriers generate ongoing rental revenue and create ongoing compliance obligations. Without periodic auditing, attachment records drift from field reality: unregistered attachments accumulate, clearance violations go undocumented, billing discrepancies compound, and pole loading data becomes unreliable. Axiom Utility Solutions provides joint use audit services for electric utilities and pole owners.

Why Utilities Conduct Joint Use Audits
Revenue verification and recovery. Pole rental fees generate ongoing revenue. Undercounted or unregistered attachments mean lost revenue. For a utility with 100,000 poles and 2-3 third-party attachments per pole, even a 3% error represents thousands in annual lost revenue. Audits reconcile billed counts against field-verified counts. Programs typically recover more than enough in back-rental to offset audit costs.
Compliance verification and liability reduction. Attachments must meet NESC clearance requirements including minimum 30 inches vertical separation between electric and communications cables, adequate ground clearance, crossing clearances, and proper grounding. Non-compliant attachments create liability for the pole owner.
Asset records accuracy and system planning. Pole databases drift from field reality over time. Audits refresh records with current conditions, improving system planning, make-ready engineering accuracy, and capital program development.
Pre-program preparation. Utilities planning pole replacement programs, distribution modernization, or broadband deployment benefit from current, verified joint use data before those programs begin.
Regulatory compliance and documentation. State commissions, NERC reporting, and FCC oversight may require documentation of pole ownership, attachment records, and compliance verification.

What a Joint Use Audit Involves
Pole census verification. Confirming count, location, classification, and ownership status against GIS records and GPS coordinates.
Attachment inventory documentation. Identifying every third-party attachment: owner, type, number of cables/strands, hardware type, and condition issues. Photographs and tablet-based data collection.
Height and clearance measurements. Measured from pole ground line and compared against NESC requirements. Catenary calculations for longer spans.
Billing reconciliation analysis. Field counts vs. billing records. Four categories: unregistered attachments, count mismatches, attachments without agreements, and lapsed payments.
NESC compliance assessment. Non-compliant attachments documented with violation type, measured clearance, required clearance, and remediation recommendations.
One-touch make-ready readiness assessment. Establishing verified baseline for OTMR programs.

How a Joint Use Audit Works: Step-by-Step
1. Scope definition and preparation. Define territory boundaries, pole count, priority areas. Obtain billing records, GIS data, agreements.
2. Field team deployment and safety coordination. Deploy crews with measurement equipment and safety gear. Coordinate with utility operations.
3. Pole-by-pole field inspection. Record pole data, GPS location, every attachment. Photograph each pole from multiple angles.
4. Height and clearance verification. Compare against NESC requirements. Document violations.
5. Billing reconciliation analysis. Compare field counts against billing records. Calculate back-rental exposure.
6. Findings compilation and preliminary report. Compliance violations, billing discrepancies, pole condition issues, safety hazards.
7. Quality assurance review. Verify accuracy. Secondary field verification for complex poles if needed.
8. Final report and action plan. Complete inventory, compliance findings, billing analysis, remediation timeline, attacher notification sequence.

What to Look For in a Joint Use Audit Firm
Trained field personnel. Understanding of NESC clearance, attachment identification, measurement equipment, documentation standards.
Current NESC and FCC Part 1 knowledge. Requirements are not static. Methodology must reflect current standards.
Systematic billing reconciliation. Clear rules for counting, identifying owners, and documenting discrepancies.
GIS integration and data delivery. Shapefiles, GeoJSON, or direct GIS import. Not paper reports only.
Post-audit support. Attacher notification, remediation tracking, re-inspection.
Volume and geographic experience. Urban vs. rural, large vs. small territories.

Joint Use Audit Support for Broadband and 5G Deployment
Accurate joint use data is a prerequisite for efficient broadband deployment. FCC’s OTMR program requires verified joint use baselines. Audit data enables: identifying poles that can accommodate new attachments without make-ready, accurate cost estimates, OTMR eligibility determination, and support for RDOF and BEAD deployment timelines.

After the Audit: Acting on the Results
Attacher notification and remediation tracking. Written findings with specific violations and compliance timelines.
Billing updates and back-rental recovery. Updated billing records and pursuit of back-billing for unregistered attachments.
GIS and asset record updates. Field-verified data integrated into GIS and asset management systems.
Establishing ongoing audit cycles. Full territory every 5-10 years. High-activity areas every 1-3 years.
