What GRL Engineers does

GRL Engineers is a private professional engineering firm headquartered in Solon (Cleveland), Ohio, providing specialized testing, analysis, and consulting services for deep foundations. The company's technology lineage traces to research conducted at Case Institute of Technology in 1964 under Professor G.G. Goble, which produced the Case Method of dynamic pile testing; GRL Engineers, Inc. was incorporated in 1976 to commercialize that research. The firm operates 14 offices across the United States with 50+ personnel and also serves international clients in the Caribbean, Central America, Northern South America, and global offshore locations.

The firm's core offerings center on a proprietary technology stack that includes the Pile Driving Analyzer (PDA), GRLWEAP wave equation analysis software, CAPWAP signal matching analysis, GRL-Cell bi-directional static load testing systems, and specialized instrumentation such as SHAPE, SQUID, APPLE, TIP, and SiteLink remote testing technology. Several of these methodologies have been codified into ASTM standards (D5882, D6760, D7949, D8169, D4633), and GRL's engineers hold Advanced Level or higher certification on the PDCA/PDI Dynamic Measurement and Analysis Proficiency Test. The firm is led by President Scott Webster, P.E., with Mohamad Hussein, P.E. as Executive Director, supported by five Principal Engineers, three Branch Managers, and field engineering staff across its regional offices.

GRL operates a project-based professional services revenue model, with pricing quoted per project scope and services ranging from small specialized testing engagements to large-scale projects involving monitoring of hundreds of test piles. Customer segments include construction contractors, state departments of transportation, airport authorities, and offshore energy operators, with named engagements including Skanska, AECOM, Granite Construction, Beaver Excavating, Richard Goettle, Colorado DOT, NICTD, Lee County Port Authority, and Venture Global. The firm has received industry recognition including the 2019 ARTBA Community Impact of the Year Award and the 2026 DFI Outstanding Project Award.

Broad incumbents

• Fugro: Fugro is a global geoscience and offshore site characterization leader providing geotechnical investigation, surveying, and foundation advisory services. It overlaps with GRL on offshore wind foundation testing and large-infrastructure geotechnical consulting, but at much greater scale and breadth.
• Arup: Arup is a global engineering consultancy with deep expertise in foundation engineering and infrastructure design. It competes for high-profile bridge and offshore wind foundation work but operates as a design firm rather than a dedicated testing specialist.
• AECOM: AECOM is a global infrastructure consulting firm that delivers large environmental and geotechnical engineering programs, including the Velsicol Superfund project where GRL also provided testing. It is both a GRL customer and a partial competitor on integrated engineering mandates.
• Braun Intertec: Braun Intertec is a multi-disciplinary engineering, environmental, and testing firm with strong Midwest presence overlapping GRL's Central Office territory. It offers deep foundation testing as part of a broader portfolio but does not match GRL's specialized dynamic pile testing scale.
• Terracon: Terracon is a large U.S. employee-owned geotechnical, environmental, and materials testing firm with national coverage. It competes with GRL on materials testing and shallow-foundation QA but lacks GRL's deep foundation specialization and proprietary dynamic testing IP.
• Stantec: Stantec is a global engineering, architecture, and environmental services firm with a strong geotechnical practice in North America. It overlaps with GRL on transportation and energy infrastructure foundation work but at a broader portfolio level.
• WSP: WSP is a global professional services firm with significant geotechnical and tunnel/bridge engineering practices. It competes with GRL on large transportation megaprojects where deep foundation testing is required as part of broader program management.

Direct peers

• Pile Dynamics (PDI): Pile Dynamics manufactures the Pile Driving Analyzer (PDA) hardware and CAPWAP/GRLWEAP-adjacent software, and historically shares a common technical heritage with GRL. It is the closest direct peer, supplying the equipment GRL engineers use, though GRL is a service provider while PDI is a manufacturer.
• Shannon & Wilson: Shannon & Wilson is a geotechnical and environmental consulting firm specializing in deep foundation design and construction support. It overlaps with GRL on transportation and infrastructure foundation testing projects, particularly in the Pacific Northwest.

Regional players

• Olsson: Olsson is an engineering firm with significant geotechnical capabilities serving the Midwest and Central U.S. It competes with GRL on transportation and water infrastructure projects but is more diversified across civil engineering services.
