TRAINING FOR MASONS
SEISMIC RETROFITTING OF BUILDINGS IN NEPAL
Introduction
This training curriculum has been developed for providing an extensive theoretical and
practical knowledge to the masons about the seismic retrofitting techniques and procedures
for different types of buildings in Nepal. In order to improve the overall safety of the
building, good retrofitting design alone is not adequate. It is very important that those designs
are appropriately implemented at the construction site. Therefore, masons are the key actors
who translate designs into reality, especially in Nepal mason are the “best technical hand” on
construction/retrofitting works. Unless the practicing masons are equipped with required
skills and knowledge in proper retrofitting techniques and tools disaster risk reduction
through seismic retrofitting of existing building will not be successful.
The training material is prepared with technical assistance of Centre of Resilient
Development (CoRD) with intensive consultation of Ministry of Urban Development
(MOUD) and Department of Urban Development and Building Construction (DUDBC) with
the support of Comprehensive Disaster Risk Management Programme (CDRMP), UNDP.
This concept note consists of goals and objectives, course contents schedule and requirements
for the mason training purpose.
Objective of the Training Program
The main objective of training program is to provide the practicing masons with basic
knowledge of retrofitting technique, tools and quality control of material and works and equip
them with required skills on retrofitting of existing vulnerable building.
This training is expected to:
Make the masons aware of the importance of appropriate working procedure at site.
Make them aware about the quality control and tests that can change the performance
of the built structure.
Enhance their skills and knowledge of masons in retrofitting technique and tools and
quality works.
Motivate the masons in retrofitting works.
Familiarize them with the Guideline on Seismic Retrofitting of Building in Nepal and
relevant safe construction practices to ensure earthquake safe construction

Training Duration:
The duration for the proposed trainings is of five days. It includes seven hours per day in
which there are 45 minutes session, two fifteen minutes tea break and one hour lunch break
each day.
Participants:
20-25 numbers of masons who already got the mason training (as possible) are
proposed in one classroom.
They should have at least one year working experience as masons, bar-benders and
should be literate.
![Page 8: S E I S M I C - Shelter Cluster · s e i s m i c retrofitting ... retrofitting techniques: adobe and masonry structures ... seismic retrofitting of buildings in nepal](https://reader031.fdocuments.net/reader031/viewer/2022021511/5ac15aa17f8b9a1c768cb4ed/html5/thumbnails/8.jpg)
vi
Resource persons:
The resource person should have minimum diploma in civil or architectural engineering with
completion of 5 days Training of trainers course (TOT) in Seismic Retrofitting of Building
and adequate experience as trainers in safe construction, capable of delivering training to
masons.
Training Venue:
Any available space within the easy locality which fulfills the requirements of a training
venue can be chosen. It should however have comfortable sitting arrangements with proper
light and ventilation and the size of the hall should be suitable for project presentation with
20-25 numbers of participants. Drinking water, lunch, refreshments and wash rooms facility
shall be available for the participants during the training session. The venue also consists of
open space of at least 40’X30’ for practical experiments/exercise and full scale construction
of model during training. Alternatively, visit and onsite training in nearby ongoing retrofitting
works as possible.
Training conduction:
The training shall be conducted according to the schedule provided.
For practical exercise and workshops, the participants will divided into smaller groups for
with at least three resource persons. Enough time has been allocated for group
work/discussion and hands on exercises. Class room teaching is proposed for clarification
and demonstration of different issues related to earthquake safety.
If possible, the equipments used during dismantling and retrofitting shall be shown to the
participants with short description.
