Natural Hazard Assessments and Technical Reviews (Public Sector)
We have been involved in the assessment and independent review of natural hazards for public sector clients. This work included evaluating geotechnical and land stability risks, reviewing technical reports and supporting documentation, and providing expert advice to assist planning, infrastructure, and development decisions. This work has given us a strong understanding of risk-based hazard assessment methodologies and the practical application of geotechnical engineering within regulatory and public-sector frameworks.

Founding story
GCE was founded by Heba Elsaidy, who relocated to New Zealand with her young family to pursue a PhD in Civil Engineering, specialising in Geotechnical Engineering. Her research focused on the challenges of problematic soil behaviour in Auckland, contributing to more resilient and sustainable geotechnical solutions.
Heba is a Chartered Professional Geotechnical Engineer with extensive consulting experience across New Zealand. She has held a number of senior technical roles, including Senior Geotechnical Specialist and CAT2P Technical Lead within Auckland Council’s Recovery Office following Cyclone Gabrielle, where she played a key role in supporting post-disaster recovery and providing specialist geotechnical leadership.
She established GCE to give clients straight answers on solid ground, drawing on 25 years of consulting experience, including close working relationships with contractors.
