Mr. Ray Meyer brings an extensive background of over 50 years in the field of Geotechnical Engineering, Construction Materials Engineering and Testing, and Forensic Investigations. His work is centered on challenges related to expansive and soft soils, soil-structure interactions, and the testing of construction materials for large, complex projects in the public and private sectors.

In his role as an Adjunct Professor in the College of Engineering at the University of Houston, Mr. Meyer instructs courses on Construction Materials Testing, and Soils Mechanics and Foundation Engineering. This teaching role has refined his ability to demystify complex engineering concepts for individuals with little to no technical background, making him adept at conveying ideas to non-engineers and those with non-engineering backgrounds.

Mr. Meyer’s career spans a wide range of civil engineering projects, where he has applied his geotechnical expertise to design and analyze structures such as bridges, waterfront structures, deep foundations (e.g., piles, auger cast piers), slabs, pavements, runways, channels, levees, and drainage systems. His work includes critical aspects of industrial paving, airport runways, side slope stability, groundwater drainage, and complex construction scenarios like cofferdams and wet wells and earth retaining structures.

Additionally, Mr. Meyer is highly experienced in geotechnical forensic investigations, which involve analyzing structure issues such as foundation failures, pavement distress, slope stability, bulkhead and pier performance, and site moisture problems. His forensic expertise also addresses issues stemming from soil movement due to environmental factors like drought and rainfall, underground utility failures, and interactions between foundations and site vegetation.

Throughout his career, Mr. Meyer has served as a subject matter expert in disputes regarding foundation and pavement performance, making him a valuable resource for understanding and resolving complex geotechnical issues in civil engineering projects.
