Its service portfolio spans geotechnical site characterization, environmental site investigation and remediation, construction materials testing (asphalt, concrete, aggregates, soils), nondestructive examination (including digital radiography and computed tomography), health and safety consulting, building science, and natural and cultural resources. Technical capabilities are anchored in advanced instrumentation including petrographic microscopy with XRD, XRF, FTIR, and SEM, pavement evaluation via ground penetrating radar and falling weight deflectometer, and a full suite of subsurface exploration methods.

The firm serves at least 13 vertical markets: aerospace, commercial, education, government, healthcare, heavy industrial, housing and mixed-use development, mission critical (data centers), oil and gas, power delivery, renewable energy, transportation, and water. Notable engagements include air dispersion modeling and permitting for the 922 MW Boswell Energy Center, geotechnical and materials testing for the Richard A. Wilkinson Middle School in Frisco ISD, and inspection services on the METRO Green Line Extension. The firm holds NADCAP, AASHTO, USACE, and ISO 17025 accreditations, and maintains wholly owned subsidiaries including Nienow Cultural Consultants (acquired June 2026) and Edwards-Pitman Environmental.

Revenue is generated through project-based professional services engagements sold directly to clients via quote-based pricing, supported by a content-driven marketing approach including a podcast, technical blog, and annual RCRA training events. The Infrastructure Corridor platform bundles services for linear projects such as highways, transmission lines, and pipelines. CEO Tim Lenway leads the firm, which remains private and employee-owned, with no disclosed parent company, external investors, or capital structure.

Core offering

Braun Intertec is an employee-owned professional services firm delivering geotechnical engineering, environmental consulting, construction materials testing, and nondestructive examination services.

Services are delivered by field-based teams dispatched from 32 U.S. offices and supported by AASHTO-, USACE-validated, ISO 17025-, and NADCAP-accredited laboratories.

Product overview

Braun Intertec is a geotechnical engineering and environmental consulting firm that operates as a service-based company rather than a software product company. The company offers an integrated suite of professional consulting services organized around core disciplines including Geotechnical Services, Environmental Site Investigation & Remediation, Construction Materials Testing, Nondestructive Examination (NDE), Health & Safety Services, Building Science, and Natural & Cultural Resources. These core services are supported by numerous specialized sub-services and industry-specific solutions across markets including Water, Transportation, Renewable Energy, Power Delivery, Oil & Gas, Mission Critical, Heavy Industrial, Healthcare, Government, Education, Commercial, and Aerospace. The Infrastructure Corridor platform provides integrated project lifecycle management for linear infrastructure projects. The company's differentiation comes from combining multiple disciplines (environmental, geotechnical, materials testing) into integrated service delivery across 32 U.S. offices.
