Key Differentiator
In-House EngineeringThat Sets the Standard
Licensed Professional Engineers. PhD-level expertise. A proprietary database built from 500+ installations over 30+ years. Our engineering team doesn't just design systems — they build them, oversee them, and stand behind them.
The Problem With Subcontracting
Most Contractors Don't Have Engineers. We Do.
The industry norm is to subcontract engineering to third-party firms. That creates communication gaps, design-to-build translation losses, and finger-pointing when issues arise. EFI's engineers sit next to our fabricators and walk our job sites. The result: tighter designs, fewer field changes, and better outcomes.
EFI's Approach
- Licensed PEs on staff, involved from day one
- Engineers work directly with fabrication teams
- Design intent preserved from CAD to field
- Real-time field adjustments by the original designer
- Single point of accountability for design + build
- 30+ years of proprietary performance data
Industry Norm
- Engineering subcontracted to third-party firms
- Designer never sees the fabrication shop
- Translation losses between design and build
- Change orders require back-and-forth with external team
- Finger-pointing when design meets reality
- Generic designs based on textbook assumptions
Cross-Disciplinary Expertise
Six Engineering Disciplines. One Team.
Licensed Professional Engineers and PhD-level specialists across every discipline required for containment and biogas system design.
Structural Engineering
Wind uplift, snow loading, ballast systems, and anchor trench design for covers spanning up to 30 acres.
Civil Engineering
Earthwork design, grading plans, stormwater management, and subgrade preparation specifications.
Process Engineering
Gas yield modeling, H2S treatment sizing, condensate management, and biogas collection system design.
Environmental Engineering
Regulatory compliance design, emission control, odor mitigation, and environmental impact analysis.
Geosynthetic Engineering
Material selection, seam design, thermal expansion analysis, and long-term durability modeling for HDPE, LLDPE, and specialty liners.
Mechanical Engineering
Flare system design, blower sizing, piping layout, and mechanical equipment specification for biogas handling.
Unfair Advantage
30+ Years of Proprietary Field Data
Every installation EFI has ever completed feeds back into our proprietary biogas and containment database. This isn't textbook data — it's real-world performance from 500+ covered lagoon digesters across every climate, soil type, and waste stream in the United States.
Predictive gas yield modeling
Forecast biogas production with field-validated accuracy, not theoretical estimates.
Structural loading analysis
Wind, snow, and rainwater loading data from installations in 45 states.
Material performance tracking
Long-term degradation data on every liner material across decades of service.
Waste characterization profiles
Biogas composition data across dairy, swine, poultry, food processing, and municipal waste.

Our Process
From Site Visit to Commissioning
A PE-led process refined over 500+ projects. Every phase is executed by the same team that designed the system.
Site Assessment
Field evaluation, waste characterization, soil analysis, and environmental baseline documentation.
On-site PE-led investigationFeasibility Analysis
Gas yield modeling from proprietary database, ROI projection, regulatory pathway identification.
Data-driven go/no-goCustom Engineering
Structural design, material specification, system sizing, and construction document preparation.
PE-stamped drawingsFabrication Specs
Direct-to-fab drawings with zero translation losses. Our engineers speak the same language as our fabricators.
CAD to shop floorConstruction Oversight
PE oversight through installation. QA/QC protocols, seam testing, and real-time design adjustments.
Engineer on siteCommissioning
Performance verification against design targets. Gas flow testing, leak detection, and system tuning.
Design vs. actual validationEngineering + Fabrication
From CAD to Field. Zero Translation Losses.
Our engineers don't just hand off drawings. They work directly with fabrication teams at three facilities to ensure design intent is preserved through every weld and every panel.
