Concept Note on Training of Trainers (ToT) to Engineers and Junior Engineers on Erathquake Resistant Building Construction in Gorkha District – aftermath of the Gorkha Earthquake of April 25th, 2015
The M 7.8 Nepal earthquake of April 25, 2015 struck at 11:56: NST, with its epicenter located at 28.147°N 84.708°E in Barpak Gorkha Area of Nepal, at a shallow focal depth of 15.0 km causing huge losses to human life and economy. The mega earthquake followed by numerous aftershocks of lower magnitude, and the M 6.8 scale aftershock with epicenter in Dolkha/Sindhupalchowk caused devastation in Dolkha, Sidhupalchowk, Gorkha and surrounding districts. The unfortunate event killed more than 8795 people and injured more than 22310 populations. Further the earthquake cause damage to more than 527829 structures in the country including numerous school and health buildings. The failure typology and pattern reveals that most of the constructions in both rural and urban areas do not comply the NBC. The workmanship and skill of the mason to construct permanent shelter and also to support un going self-help recovery has emerged as crucial factor for creating earthquake resilient community. There is a lack of skills across the general population on building permanent safe shelters therefore need of ToT and the on job training.
In this background CoRD developed IEC materials and 4 prototype design; Stone masonry in mud mortar with GI wire, CSEB masonry building, Stone masonry with RC bands and Stone masonry with wooden band align with MRT – National Building code of Nepal. CoRD intends to carry out trainings to Engineers, Masons and labours on safer and greener construction techniques through ToT and on job training with construction of building. Community and other stake holders also will aware on safer construction through demonstration.
DUDBC has carried out numerous activities and published numerous documents in collaboration with national and international development partners to facilitate the NBC implementation in LBs. Some of the praiseworthy efforts are
The Department of Urban Development & Building Construction (DUDBC) by virtue of the provisions and clause of the “Building Act 2055 (first amendment 2064) is the lead agency in formulation, enforcement, implementation, mentoring and monitoring of National Building Code throughout the country. In this regards, DUDBC has a long experience in the process of formulation, implementation and capacity building of LBs as well as other government agencies and private sectors. Recently DUDBC prepare and disseminate curricula for training of trainers and mason training on earthquake resistant construction.
Rationale of the Training
More than 527829 buildings collapsed and more than 277841 damaged which shows there is a lack of knowledge and practice in safer construction techniques. Therefore there is a need of huge reconstruction program, likely to take more than 3 – 5 years which will need of large number of skill masons, technicians and engineers. In same time self-help recovery is also in progress therefore to ensure built back better and safer there is need for skilled human resources.
The rapid damage assessment carried out by CoRD, NEA and other institutions revealed the fact that more than 50% of the damaged buildings could be used after minor or moderate level of retrofitting and repairs. Similarly, most of the buildings have collapse or damaged mainly due to poor workmanship, poor materials and non-compliance of NBC. Therefore, it has been concluded that there is need for skilled masons on one hand and affordable and local technology for retrofitting and new building construction on the other hand. Therefore a customized Mason training could be proved very crucial for enforcement of NBC at local level and imparting new technology. In same time there is need of construction of thousands of permanent building in limited time, therefore need to explore material, technology based on local resource and economy.
The workmanship and skill of the mason to comply the NBC has emerged as crucial factor for creating earthquake resilient community. Majority of the buildings in the earthquake affected districts have experienced minor to major cracks in load bearing and partition walls which need retrofitting and maintenance.
In this background DUDBC/CRS/CoRD intends to carry out trainings of trainers to engineers, junior engineers as per DUDBC compliance training guidelines.
Objectives of Training:
The overall objective of the training is to improve the skill of masons in earthquake affected district to carry out repair maintenance; retrofitting and new constructions as per the national building code, including the introduction of new technologies.
The specific objectives of the program are:
- To train engineers / junior engineers / technicians on NBC compliance construction technology
- To train engineers / junior engineers / technicians on training skills and techniques
To train the engineers / junior engineers / technicians to take the challenges for repair of minor damaged buildings
Topic to be covered
Learning by doing will be the major approach for the training. Discussion on basics of earthquake and behavior of different type of buildings and their failure during earthquake will be discussed. The current construction practice and need of improvement will be discussed in interactive manner. This will be followed exercise sessions.
- Earthquake Basics and Effects of Earthquake
- Building Configuration
- Earthquake resistant design philosophy, Behavior of Earthquake resistant components in RC Structure, earthquake load calculation
- Ductile detailing of RC structural components as per IS 13920; general requirements and calculation procedure
- Behavior of earthquake resistant member of masonry building its detailing
- Quality control
- NBC status and implementation strategy
- Repair and maintenance
- Retrofitting technique
- NBC 202, 203 and 205
