Workflow B: Existing Tower Audit

Goal: Model an existing tower to verify current structural capacity.

Process Flow​

Input as-built geometry ──> Match existing sections ──> Model current assets ──> Analyze ──> Report

When to Use This Workflow​

  • A TowerCo needs to verify capacity of an acquired tower
  • A tower needs re-certification after modification
  • You need to assess remaining capacity for new tenants
  • Regulatory compliance requires updated structural analysis

Tips for Accurate Modeling​

Important

The accuracy of your analysis depends entirely on the accuracy of your model. Take extra care with as-built data.

  • Match section profiles exactly to as-built drawings — use the closest profile in the library
  • Include ALL existing appurtenances — missing antennas, cables, or ladders will underestimate loading and overestimate remaining capacity
  • Verify exposure category against actual site conditions, not just the original design assumptions
  • Compare results against any existing analysis reports for validation before issuing a new report
  • Document assumptions — note where as-built data was unclear or estimated

Output​

After analysis, you'll have:

  • Unity check ratios for all members under current loading
  • EPA breakdown per section showing wind area contributors
  • BOM with actual tower weight
  • Base reactions for foundation assessment
  • Shareable link for client or regulatory review
