Its in-house Soils and Rock Testing Laboratory is accredited by the AASHTO Accreditation Program and validated by the U.S. Department of the Army Corps of Engineers, enabling a comprehensive suite of geotechnical testing (sieve analysis, Atterberg limits, triaxial compression, consolidation, hydraulic conductivity, among others). YK Drilling, LLC, a wholly-owned subsidiary established in 2009, provides in-house geotechnical, environmental, and water-well drilling across Hawaii and the Pacific using a fleet of seven drill rigs with sampling depths from 5 feet to 720 feet in basalt rock.
The firm operates as a professional services business on a project-based engagement model, serving government agencies and civil engineering clients in Hawaii. Named engagements span municipal wastewater infrastructure (Honouliuli Wastewater Treatment Plant, Awa Street Pump Station, Kaneohe-Kailua Conveyance Tunnel, Ala Moana Pump Station Force Mains), airport infrastructure (Runway 8L at Daniel K. Inouye International Airport, South Ramp Taxiway at Ellison Onizuka Kona International Airport), state DOT work, and federal/military projects (Pearl Harbor underwater waterline crossings). The company is recognized regionally and nationally with awards from ACEC Hawaii, ASCE Hawaii, ACEC national, AGC of America, and APWA across more than 30 documented projects.

Yogi Kwong Engineers competitors and assessment
Company assessmentBroad incumbents
- Stantec: Global engineering, architecture, and environmental services firm with significant geotechnical and infrastructure practices. Comparable to YKE on geotechnical engineering, construction management, and infrastructure consulting, though at much broader scale.
- AECOM: Global infrastructure consulting firm with extensive geotechnical, tunneling, and construction management capabilities for airports, water, and transportation. Comparable to YKE on technical scope but with vastly larger scale, geographic reach, and prime-contractor capacity that competes for the same Hawaii-region RFPs.
- WSP (formerly Golder Associates geotechnical practice): Global professional services firm with a large geotechnical, tunneling, and earth sciences practice (via the Golder legacy). Comparable to YKE on trenchless engineering and geotechnical consulting, but operating at global scale across many end markets.
Direct peers
- Kleinfelder: Engineering, scientific, and construction management consulting firm with strong geotechnical, environmental, and construction services practice. Comparable to YKE in offering integrated geotechnical, construction management, and lab/drill services to infrastructure clients.
- Pacific Geotechnical Engineering (PGE): Hawaii-based geotechnical engineering firm offering subsurface investigation, soils testing, and construction support services for state, municipal, and private infrastructure clients—directly comparable to YKE on service mix, customer base, and Hawaiian operating geography.
- Shannon & Wilson: Geotechnical and environmental consulting firm specializing in tunneling, dams, landslides, and complex subsurface work—directly comparable to YKE's trenchless and dam/lanslide mitigation practices and award-winning civil project portfolio.
- Haley & Aldrich: Engineering and environmental consulting firm focused on infrastructure, water resources, and energy projects with deep geotechnical expertise. Comparable to YKE on subsurface investigation, dam/levee work, and complex urban infrastructure engagements.
- Terracon Consultants: Large U.S. geotechnical, environmental, and construction materials engineering firm with extensive drilling and lab capabilities nationally. Closely comparable to YKE's integrated lab-and-drilling model, though at national scale and across broader end markets.
Regional players
- R.M. Towill Corporation: Hawaii-based civil engineering, planning, and construction management firm. Comparable to YKE on Hawaii infrastructure focus and construction management offerings, primarily serving Pacific-region public-sector clients.
Others
- YK Drilling, LLC: Wholly-owned drilling subsidiary of Yogi Kwong Engineers providing geotechnical, environmental, and water well drilling throughout Hawaii and the Pacific. Included as an OTHERS peer because it is part of YKE itself, illustrating the firm's in-house drilling capability versus third-party drilling subcontractors like Boart Longyear or Cascade Drilling.
