Methodology
Rafael's approach integrates thorough site characterization with advanced analytical methods. He prioritizes understanding the geological context through detailed desk studies and field investigations, including borehole drilling and in-situ testing per ASTM D1586. His design philosophy emphasizes reliability and robustness, using limit state design principles aligned with New Zealand standards. Rafael collaborates closely with structural engineers and contractors to provide practical, constructible solutions that address both short-term construction risks and long-term performance. He maintains a strong commitment to continuous professional development and incorporates lessons learned from project reviews into future work.

Local Considerations — Rafael Souza Carvalho
With decades of experience across New Zealand, Rafael has developed deep insight into the region's varied geology, from the volcanic soils of Auckland to the alluvial deposits of Canterbury and the hard rock of Otago. He understands the challenges posed by high seismicity, high groundwater, and soft soils, and applies site-specific solutions that respect local conditions and regulatory frameworks.

Frequently Asked Questions
What types of projects does Rafael typically work on?
Rafael has extensive experience in residential, commercial, and infrastructure projects, including high-rise buildings, bridges, retaining walls, and slope stabilisation. He also works on land development and ground improvement schemes.
How does Rafael approach seismic geotechnical design?
He follows NZS 1170.5 and uses site-specific response analysis, liquefaction assessment, and soil-structure interaction modelling to ensure designs are resilient. He incorporates both code-based and advanced numerical methods as needed.
What is Rafael's role in site investigations?
Rafael oversees the entire investigation process, from planning borehole locations to supervising fieldwork and interpreting results. He ensures that investigations are tailored to project needs, using appropriate in-situ and laboratory tests to characterise ground conditions.
