Forensic Services - Infrastructure
Raba Kistner’s Forensic Services are needed when distress, deterioration, failure, loss of function, or reduced performance occurs in architectural or engineered building assemblies, components, or equipment.
Construction Materials and Engineering Testing (COMET)
Reliable construction outcomes depend on the performance of the materials and systems used. Kiwa delivers accredited Construction Materials and Engineering Testing supported by advanced laboratories, certified technicians, and the multidisciplinary construction expertise of Raba Kistner and Sequoia Consultants. Our integrated approach ensures that every project is built safely, efficiently, and in compliance with all applicable standards.
What We Do

Geotechnical Engineering
Our geotechnical professionals provide subsurface evaluations and recommendations that guide design, construction, and long‑term performance.
Construction Oversight & QA/QC
Inspired by Sequoia’s strengths, Kiwa offers expanded construction support services:
- Construction quality assurance and quality control programs
- Owner representation and construction oversight
- Project controls, scheduling, and cost monitoring
- Risk‑based construction monitoring and documentation
These services help owners maintain visibility, reduce risk, and ensure that construction aligns with design intent.
Why Quality Assurance Matters
Materials that fail to meet specifications can lead to safety concerns, costly delays, and long‑term maintenance issues. Independent testing and inspection provide objective verification that materials are produced, delivered, and installed correctly.
Our integrated testing, inspection, and oversight approach helps:
- Identify issues early
- Maintain code compliance
- Reduce rework and schedule impacts
- Improve documentation and transparency
- Support long‑term structural performance
