What Eustis Engineering L.L.C. does
Eustis Engineering L.L.C. is a privately held civil and geotechnical engineering firm founded in 1946 and headquartered in Metairie, Louisiana. It provides a five-part service suite: geotechnical exploration and laboratory testing (soil borings, CPT, field vane shear, classification and consolidation analysis), geotechnical engineering (shallow and deep foundation design, slope stability, seepage, ground improvement, and Soil Structure Interaction modeling using Finite Element Method), geotechnical instrumentation for long-term monitoring, construction materials and deep foundations testing (including Dynamic Pile Testing, static load testing, pile integrity testing, and thermal integrity profiling), and IBC Chapter 17 special inspections. The firm was the first private consulting firm in Louisiana and Mississippi to own Dynamic Pile Testing equipment and operates its own fleet of field and laboratory equipment.
The firm serves federal, state, and local government agencies; industrial entities (petrochemical, manufacturing, steel); private developers; and educational institutions, with named engagements including St. Tammany Parish coastal flood protection, Bayou Chene Flood Control Structure (described as the largest flood gate of its kind in the world), the Hyundai Louisiana Steel Mill, Marathon Petroleum reactor work, and the Domino Sugar Chalmette modernization. Revenue is generated through project-based professional services fees determined by scope and complexity, with no public pricing. Distribution is direct, with engineering teams delivered from six offices: Metairie, Baton Rouge, and Lafayette, Louisiana; Gulfport, Mississippi; Houston, Texas; and Glastonbury, Connecticut, the last opened in June 2025 to anchor a Northeast regional practice supported by an affiliated New York entity.
The company is independently owned since founding, with no disclosed private equity, venture capital, or institutional investment. Governance is led by President Gwen Sanders, P.E. and Vice Presidents including Sean G. Walsh, P.E. (Northeast), and James J. Hance. The firm holds AASHTO, CCRL, and A2LA laboratory accreditations and government procurement credentials (CAGE and UEI), completed the GBA Peer Review in April 2025, and maintains leadership roles across ASCE, ACI, AWS, PDCA, GBA, and SAME. Headcount is reported as 100+ with no public revenue disclosure.

Products and services
- Geotechnical Exploration & Laboratory Testing Subsurface investigation services for construction and infrastructure projects on the Gulf Coast, including soil borings, cone penetration testing (CPT), field vane shear testing, and laboratory analysis of soil samples for classification, strength, and consolidation properties. Targeted at government, industrial, private developers, and educational institutions needing site characterization.
- Geotechnical Engineering Engineering analysis and design services covering shallow and deep foundations, slope stability, seepage analysis, consolidation settlement, braced excavations, site dewatering, ground improvement, and Soil Structure Interaction (SSI) modeling using the Finite Element Method (FEM). Targeted at engineering firms, EPC contractors, public agencies, and industrial owners undertaking construction projects in soft Gulf Coast soils.
- Geotechnical Instrumentation Installation and monitoring of geotechnical instruments for cost optimization, design refinement through full-scale testing, and verification of structural performance via long-term monitoring programs. Used by infrastructure and industrial owners to extend design life of structures and reduce earthen preload durations.
- Construction Materials & Deep Foundations Testing Comprehensive construction materials testing and inspection including earthwork, piling, concrete, steel, and advanced deep foundations testing using Dynamic Pile Testing (DPT), static load testing (compression, tension, lateral), low strain Pile Integrity Testing (PIT), Thermal Integrity Profiler (TIP) testing, and cross-hole/single-hole sonic logging (CSL or SSL). Capabilities include testing in marsh, swamp, open water, and underwater environments. Targeted at general contractors, specialty contractors, and asset owners.
