After Canoa, we next headed north to Jama, another coastal town. In Jama we selected a street in town and compared the building type and performance of each, one-by-one. There were 7 houses, some with commercial space below. Six houses were wood framed, 2-stories, and one was reinforced concrete, 3-stories. Of the wood framed, 5 had masonry infill at the ground floor and 1 had bamboo lath with plaster overlay at the ground floor. Four had wood only walls at the upper level while two had mixed wood and masonry infill walls at the upper level. In general of the … Read More
This morning we met with Ing. Hermel Flores, owner of Hermel Flores Construcciones and former chair of the Ecuatorian Chamber of Construction, and General Florencio Ruiz Prado, Director of Citizen Security for Manta, in Manta. We discussed our activities, the situation and the presentation they coordinated for us to give on Tuesday and Wednesday, in Manta and Portoviejo, respectively. Ing. Flores traveled with us next up north towards the epicenter. The coast of Ecuador is in the highest seismic zone of the country. There are RENAC sensors located up and down the coast which recoded the accelerations in the recent … Read More
May 1st was our first full day in Ecuador, after landing in Guayaquil on April 30. Our team has three members: Traveling from our Bogota office there is Juan Caballero, architect and Director of Programs and Partnerships for Latin American, and Walter Cano, structural engineer and Project Engineer for Colombia. From the U.S./headquarters there is Lizzie Blaisdell, structural engineer and Director of Engineering. In Guayaquil, we saw little evidence of an earthquake. According to the preliminary report on the Instituto Geofisico website (http://www.igepn.edu.ec/) a strong motion sensor near Guayaquil, “AGYE” experienced a maximum ground acceleration of 23.04 cm/s2 (approx. 2%g) while … Read More
Click here for link to Autodesk Foundation video. “We can build buildings to withstand earthquakes. The knowledge and technology are out there. We just have to make it accessible to everyone.” – Elizabeth Hausler Strand, Founder & CEO, Build Change In Colombia, we are working with city governments, the private sector, and homeowners to repair and strengthen homes before the next earthquake strikes. Retrofitting saves lives by ensuring that houses will protect families and children from future natural disasters. We started out retrofitting a single house in Bogotá, Colombia, to provide an opportunity for local training and to demonstrate feasibility. Jorge Prada’s family now lives … Read More
A second strong earthquake struck Nepal on May 12, 2015. We are relieved to report that our team reported in and they are unharmed. The families in the small village they were in when it struck are also unharmed. “We are all fine. At the time of the first M7.3 earthquake near noon, we were in a very remote village, Thulo Guan, Balthali, an hours’ drive from Kathmandu on a rutted, narrow dirt road along a cliffside. No one was hurt in this village. We were standing on the 2nd floor of a relatively undamaged house (newer construction from about 2008) … Read More
Over 150 adults and 100 children participated in our Better Building Material community event in Takengon, Indonesia in December 2014. We have been working with 200 local brick-makers, mostly women, to help them produce better quality bricks. Houses and schools built with poor-quality bricks or concrete blocks are likely to collapse during natural disasters. Better bricks and concrete blocks make safer houses and schools. We provide on-the-job training for small businesses that manufacture bricks and blocks to improve the quality of their products. We also offer business skills training in management, budgeting, and more efficient manufacturing techniques. We conduct public outreach … Read More
“I want to advise other young women like me to not choose only nursing, accounting, or secretarial work. Dare yourself to learn other trades,” Widleine George says. She stands outside in her construction training station, where she demonstrates proper techniques to trainees and oversees the masons’ progress. “I receive a lot of respect because of my position, because it’s not typically a woman’s job,” she says. “I want to advise other young women like me to not choose only nursing, accounting, or secretarial work. Dare yourself to learn other trades.” Widleine comes from Carrefour-Feuilles, one of the areas of Port-au-Prince that was severely damaged by the earthquake in … Read More
We are inspired by this Verizon video, described in the Huffington Post. “A new Verizon commercial cites a sad statistic by the National Science Foundation: 66 percent of 4th grade girls say they like science and math, but only 18 percent of all college engineering majors are female. People have offered many potential explanations for this discrepancy, but this ad highlights the importance of the social cues that push girls away from math and science in their earliest childhood years.”
After the 2009 earthquake in West Sumatra, the government of Indonesia strongly discouraged the donor and NGO community from building transitional shelters, or T-shelters. Instead, they recommended providing technical assistance and cash grants. In Haiti, T-shelters were implemented in large numbers after the 2010 earthquake, taking time and resources away from providing a more permanent solution. Temporary shelters may be unavoidable in some harsh climates, but most of the world is well positioned to abandon this temporary fix and move directly to permanent housing.
Retrofitting, or strengthening a building to withstand the next earthquake or typhoon, is an efficient and safe way of putting existing stock back in play after a disaster. It can be done at a cost equivalent or lower than temporary shelters. If done in tandem with a large-scale effort to build capacity of local engineers, architects, and construction professionals, it can be done efficiently and at scale.
The government of India (in partnership with the World Bank) had it sorted out after the 2001 Bhuj, Gujarat earthquake. Provide a clear and simple guideline, provide cash grants in installments contingent upon following those guidelines, and provide third party technical assistance to coach homeowners and builders through the process. Why has it taken the rest of the donor and aid community so long to catch up? After the Indian Ocean tsunami, the NGO community insisted on donor-driven housing, lured by the perceived need to get houses built quickly and the efficiency of scale. Shortcomings of past donor-driven housing reconstruction … Read More
More than half of the world’s population is now living in urban areas, increasing the risk of large-scale urban displacement due to natural disasters such as earthquakes, typhoons and tsunamis. When a city’s housing stock is damaged or depleted due to a disaster, it puts a strain on the city’s ability to respond and recover, as public and private spaces are filled with temporary shelters and the affected populations – necessary to the recovery effort – live in insecurity. This problem is exacerbated in developing countries. Rental support is an intervention gaining usage worldwide to address the need for housing … Read More
Homeowners don’t steal from themselves. Put them in charge of reconstructing their home, and they reuse materials. Often, they contribute their own funds. And their degree of satisfaction is so much higher than if we give them a house that they don’t trust is safe. We’re not asking them to use sweat equity and build the house themselves; in that case, we would miss the opportunity to train local builders who will go on to build many houses, and put money back into the local economy. We’re talking about empowering homeowners to make their own decisions on materials and architecture, … Read More
Build Change has relied primarily on paper-based inspection checklists and manual filing of photographs for collecting data on homeowners, trainees, and compliance rates of houses. This system can work on small projects, but it has limitations, including time lag between data collection, interpretation, and decision-making, and opportunities for errors and corruption. We have started an ambitious switch to digital, in partnership with the Grameen Foundation and using Taroworks and Salesforce.
“It helps to solve problems during construction and adds to my knowledge to make good choices during building.” This is the feedback from Tukiran, a homeowner Build Change is supporting to rebuild safely after the July 2013 earthquake near Takengon, Aceh. Preliminary indications are the text messaging is a simple, fast, inexpensive method for sharing information about the basics of safe construction. More efforts are underway to further quantify the impact.
Girls in STEM, featuring young women scientists and engineers who wowed the President and the nation at the White House Science Fair in February, shines a spotlight on these extraordinary young role models and their exciting projects — ranging from a machine that detects buried landmines, to a prosthetic hand device, to a lunchbox that uses UV light to kill bacteria on food. http://www.pbs.org/newshour/rundown/girls-stem-take-center-stage-white-house-science-fair/
Build Change CEO Elizabeth Hausler Strand recently attended both the World Economic Forum on Latin America and the World Economic Forum on East Asia, connecting with economic issues related to our disaster risk reduction program in Colombia and our post-disaster recovery programs in Indonesia and the Philippines. Build Change presented at the World Urban Forum in Medellín, Colombia in early April to encourage the use of retrofitting as a cost-effective approach that makes buildings safe and fosters community resiliency.
Our Chief Operations Officer took this photo in Haiti today. “T-shelters” or “transitional shelters” are a popular solution in post-disaster situations. They’re built to withstand earthquakes and hurricanes, to keep residents from being displaced again. They are expensive and subtract funds which could be used for retrofitting damaged homes or rebuilding homes. A family is living in this t-shelter, which is three years old now and clearly deteriorating. By some estimates, the [2010 earthquake in Haiti] killed 200,000 people and made 1.3 million homeless overnight by destroying or damaging 172,000 homes or apartments. But the new projects do not necessarily … Read More
Look at the top of the wall. The decision to lay the top course of blocks on its side for extra ventilation was an extremely bad one, making it so the seismic load in the roof slab has no competent load path to the shear wall below. In the retrofit evaluation our engineers give this wall no credit for seismic resistance–it will have to be fixed.
