Geospatial and Geophysics
What We Do
Geophysical
Kiwa’s deep geotechnical and geophysical experience, delivered by Kiwa T2 professionals, provide clients with scientifically robust foundational data to support successful project construction. Geophysical techniques complement traditional methods of underground utility investigation and allow the targeted use of non-invasive technologies to image subsurface conditions through measuring, analyzing and interpreting physical properties. Our skilled teams offer advanced geophysics to collect reliable data for use in infrastructure planning, archaeological, and environmental uses. We apply our experience and knowledge to recommend the right methods to deliver clear, actionable data that reduces uncertainty.

Advanced geospatial surveying and mapping
Advanced geospatial surveying and mapping services begin with site-specific data collection by highly trained and technically outfitted field technicians following rigorous data collection and Quality Assurance procedures. The data flows through processing and analysis. Professional judgment, knowledge of local jurisdictional requirements, insights are added to prepare reliable deliverables.
Core Geospatial offerings
- As-Built Records / ASCE 75 Standard
- Utility mapping, designation, and verification
- Subsurface imaging
- No-entry confined space scanning
- GIS asset management
We produce deliverables compatible with:
- GIS
- CAD
- BIM
- 3D digital twins
- Asset management systems
- ASCE 75 / As-Built records

This comprehensive approach ensures accurate mapping of utilities, ground conditions, and surface features—reducing uncertainty and improving project outcomes.
Why This Expertise Matters
Underground utilities, buried infrastructure, and subsurface anomalies are among the most significant risks affecting modern construction and transportation projects. Inaccurate or outdated records can lead to structural and construction issues, design conflicts, utility strikes, schedule delays, and safety incidents. High-quality geospatial and geophysics data supports better decisions and more predictable constructability.
Whether planning a major capital project, roadway expansion, utility relocation, or facility upgrade, our teams deliver the subsurface clarity needed to move forward with confidence.
How Kiwa Delivers Value
Kiwa T2 applies multi-technology geophysical investigations and digital data integration to create accurate, usable information for designers and planners. We provide outputs that are compatible with CAD, GIS, BIM, and other engineering platforms, helping stakeholders visualize conditions in three dimensions and coordinate more effectively.
