In 2009, the GCI initiated the SRP with the objective of adapting GSAP techniques to better match the equipment, materials, and technical skills available in many countries with earthen sites. Using four Peruvian historic earthen buildings representing typologies across Latin America, the GCI—in collaboration with the Ministerio de Cultura del Perú, the and maintenance programs with locally available Escuela de Ciencias e Ingeniería of the Pontificia Universidad Católica del Perú, and the University of Minho—is designing, testing, and implementing seismic retrofitting techniques and maintenance programs with locally available materials that will improve the structural performance and safety of earthen buildings while minimizing loss of historic fabric.
