Transportation Infrastructure - Inspection, Risk Management, and Quality Assurance
What We Do
Kiwa supports the full lifecycle of transportation projects, from early planning and feasibility through construction and long-term asset management. Our teams deliver the data, testing, and engineering insight needed for design teams, general contractors and owners to make informed decisions that improve design reliability and assure construction quality.
Our capabilities include
- Archaeology / Cultural Resources Investigations
- Environmental Due Diligence / Site Assessments
- Environmental Planning & Permitting
- Environmental Compliance Management
- Feasibility studies and risk management
- Geoscience / Geospatial investigations
- Geophysical consulting
- Construction and site inspection
- Geotechnical engineering
- Materials, pavement, and product testing
- Construction quality assurance
- Subsurface utility engineering (SUE) investigations and utility risk management
- Utility conflict identification and coordination
- Geospatial investigations and mapping
- Lifecycle asset and condition assessments
Why This Expertise Matters
Transportation assets face demanding operational conditions: heavy loading, environmental exposure, aging structures, and complex construction requirements. Both planned and unforeseen impacts can create significant financial, operational, and safety risks.
Independent engineering, testing, and utility intelligence help project teams:
- Reduce construction and operational risk
- Verify that materials, systems, and utilities meet regulatory and industry standards
- Identify and mitigate utility conflicts early
- Reduce the impact of undocumented or unknown utilities on design
- Support resilient design and extend asset life
- Provide reliable data to guide decision making during design, construction, and maintenance
