LOI Infrastructure Experience


LOI has been involved in all phases of construction for all the surrounding school districts, from new construction to facility improvements.

We have provided environmental and geotechnical engineering services and construction quality control testing.


LOI has vast experience in providing environmental, geotechnical, and construction materials testing for a variety of health facilities. Some of these facilities are listed as follows: UMC, Urgent Care, Child Crisis Center, New Johnsen Animal Hospital, La Clinica, and Various Medical Complex facilities to name a few.


We have been a part of various warehouse site developments from site assessments to the completion of the warehouse construction.

Our extensive experience includes warehouse facilities to dealerships like the SDI in Cd. Juarez, Mexico to Poe Toyota in El Paso, Texas.


LOI has participated in residential projects like HACEP Harry S. Truman Memorial Complex, Montecillo Subdivisions, Cumbre Estates, Sereno Valley Estates, River Run Heritage Farms to name a few. We also provided our services for commercial developments, like Starbucks, Fred Loya Claim Center on Pelicano Dr., Eastlake Market Place, Panda Self Storage, Top Golf, I-Fly.

Our Core Business. January 2012 is the date when LOI ENGINEERS commenced to provide construction observation, quality control materials testing and engineering, exploration services, and environmental consulting services as a stand-alone firm (TBPE F-14023), under the leadership of Bernardino (Berna) Olague, P.E.
