Dr. George Nez serves as a technical advisor on TSC Hypar roof systems. Formerly a city planning director and professor, he has served in UN and USAID development projects in Ghana, Egypt, the Persian Gulf countries, Thailand, S. Korea, and coordinated post-earthquake planning of Skopje, Macedonia and Managua, Nicaragua. In Ghana he initiated roofs-first preparation of 20 new and enlarged villages for emergency resettlement, in the Volta Basin hydroelectric program, where the roofs-first construction allowed families to move into their own new houses and complete walls using traditional methods. Since retirement he has continued training: for the Nuba Water Project of South Sudan, for the Birambye L’Esperance Orphanage project in Rwanda, the Sheik Yassin school in Wardak Afghanistan, introducing bamboo framed thin shell roofing in Bangladesh Architectural Research Institute, and thin-shell roofing over compressed earth brick walls in Uganda. He has researched this system since 1980 along with engineers Evan Curtis of National Park Service and Albert Knott of Knott Testing Laboratory, Denver.
