Sub-Stations and T-Line Civil Infrastructure
We deliver precision civil work for substations and transmission line foundations — built to spec, properly compacted, correctly drained, and ready for the client to begin the next phase of construction.
Civil Infrastructure That Electrical Crews Can Trust
Substations and transmission lines don’t tolerate guesswork. If elevation is off, compaction fails, drainage is wrong, or conduit isn’t set correctly, the entire schedule backs up — and electrical crews sit waiting.
Tricon’s civil teams execute from raw dirt to finished top rock with layout precision, compaction discipline, grounding grid integration, and manpower depth to keep utility projects moving without costly rework.

- Transformer, breaker, and flatwork foundation construction
- Engineered compaction with third-party verification
- Grounding grid and conduit installation
- Transmission line drilled pier foundations
- Drainage planning and erosion control
- High-manpower mobilization to compress utility schedules

Case Study Overview
On a recent utility substation project in Louisiana, Tricon was contracted to deliver the full civil scope for a new substation tied to a transmission expansion. The work included precision grading, engineered compaction, drilled pier construction, transformer and breaker foundations, grounding grid installation, conduit placement, and final rock finish — all sequenced around strict utility tolerances and electrical mobilization.
From the start, elevation control and foundation accuracy were critical. Drilled piers were constructed with precise rebar placement and anchor cage alignment to meet structural load requirements, while transformer and breaker foundations were poured to exact elevation and anchor bolt tolerances. Our team executed disciplined lift-by-lift compaction with coordinated third-party density testing to eliminate settlement risk before electrical crews mobilized.
Grounding grid and conduit systems were installed with layout verification at every phase, ensuring seamless integration with the electrical design. Continuous benchmark checks and inspection coordination prevented correction cycles and allowed downstream trades to move without delay.
As schedule pressures tightened, we scaled manpower strategically to accelerate production while maintaining structural precision and documentation discipline. Drainage and surface stabilization were built into the grading plan to prevent erosion and long-term pad instability.
The result was a fully prepared, specification-compliant substation delivered on schedule and handed over clean — reinforcing Tricon’s role as a trusted civil partner for high-voltage utility infrastructure where foundation accuracy and sequencing discipline matter most.

FAQs
Find answers to common questions about our services and how we can assist you.
How do you ensure compaction meets utility specifications?
We follow engineered lift plans and coordinate third-party density testing at each phase. No area moves forward without documented verification, ensuring long-term stability and preventing settlement issues.
How do you coordinate civil work with electrical sequencing?
We maintain continuous layout verification and direct communication with field engineers so grounding grid, conduit, and elevation benchmarks align precisely with electrical design requirements.
Can you work around energized infrastructure or live sites?
Yes. Our crews understand clearance requirements, access control, and safe work planning within active utility environments, minimizing disruption while maintaining compliance.
How do you prevent drainage and erosion failures on substation sites?
Drainage planning is integrated into grading from the start. We build to direct water flow properly and protect pad integrity to avoid washouts or long-term instability.
What happens if the schedule tightens mid-project?
We have the manpower depth to scale quickly. Additional crews can be deployed to accelerate production while maintaining precision and documentation standards.
