Substation Structural & Foundation Engineering

Full-scope structural and foundation engineering for substations from 69 kV to 765 kV, including collector substations for renewable energy and transmission substations for utilities.

Services include:
- Transformer foundations with oil containment systems
- Drilled shaft, helical pile, and spread footing foundation design
- Steel support structures — A-frames, dead-ends, bus supports, switch supports, lightning masts
- Seismic qualification per IEEE 693-2018 and ASCE 7
- Bus and switch support structure analysis per ASCE 113
- Anchor bolt and base plate design
- Equipment loading evaluation and reinforcement recommendations
- Foundation reaction envelope development from PLS-CADD outputs
- Structural analysis using RISA-3D and PLS-POLE
- Engineer of Record (EOR) services through IFC
- Oil containment foundation systems for inverters
- Specialty structural engineering (airport vaults, underground manholes, blast-resistant designs)

Design and analysis performed in accordance with NESC, ASCE 113, IEEE 693, AISC, and AASHTO standards. Experience includes new substation design, upgrades, and peer review for major utilities and renewable energy developers.
