Our Core Services

We supply complete engineering dossiers required for utility line compliance.

Construction Drawings

Complete structural plans showing what equipment, conduits, and cabling systems to install to integrate perfectly with active baseline configurations.

  • Comply with all updated PG&E specifications & layouts
  • Easy to read and deploy for structural joint trench framing crews
  • Includes structural component calculations directly on draft plans

Mandated Engineering Calculations

Full spectrum math parameters to clear municipal and infrastructure plan-check processes easily.

  • Transformer sizing & line load profiles
  • Secondary & service voltage drop metrics
  • Conductor maximum pulling tension safety analysis
  • Voltage rise evaluation for commercial solar field installations

Material Lists & Quantities

Detailed logistical frameworks built directly to clear supply acquisition pipelines without error.

  • Breaks major structures down into easy installation tasks
  • Totalized item sheets simplify structural wholesale purchasing
  • Prevents logistics overhead delays due to missing structural couplers or lines

OCalc Overhead Pole Analysis

Sophisticated multi-variant software modeling to check line tension, asset load constraints, and physical compliance limits.

  • Full compliance modeling keeping projects aligned to General Order 95 safety rules
  • Determines exact structural anchor points and down-guy safety loads
  • Joint Pole Association coordination maps to streamline multi-tenant line shares

On-Site Field Surveys

Direct physically mapped conditions verification keeping modern designs completely aligned to real-world structural bounds.

  • Accurate field measurements capturing existing run coordinates
  • Topographical verification minimizing unexpected grading construction blockades
