Thesis proposal – Comparative Structural Optimization of Interlocking Bricks for Sustainable Housing in Nepal
Engineers Without Borders Sweden is a volunteer based and value driven organization Engineering for Humanity. For over 15 years, we have been driven by a single goal: build a sustainable future for communities around the world. With sustainability and long-term thinking as guidance, we mobilize our engineering expertise to provide innovative solutions empowering communities today and ensure their resilience tomorrow.
Background
EWB is partner of Build up Nepal (BUN), that was established following the 2015 earthquake in Kathmandu. BUN focuses on promoting compressed bricks made from a mixture of stone dust or soil, cement, and water. These bricks are produced using machines provided to small enterprises. Since its inception, BUN has supported over 300 small companies, contributing to the construction of more than 10,000 houses across Nepal. Their efforts have significantly reduced carbon emissions by 100,000 tonnes and created over 2,000 full-time jobs, with women making up a quarter of the workforce. Interlocking bricks, designed like LEGO blocks, are BUN's main product. These bricks are not only easy to assemble but are also earthquake-resistant, making them particularly suitable for construction in earthquake-prone regions like Nepal. Some illustrations:

About the position
The interlocking bricks feature holes that allow for the placement of reinforcement, thereby enhancing earthquake resistance. This solution is presented as a safer alternative to traditional houses constructed with burnt bricks. However, a structural comparison between these two construction methods using the Nepal Standards has not yet been conducted. (The guidelines for the compressed interlocking bricks are yet to be published, though a draft is available.)
The aim of this work is to confirm the viability of the interlocking brick solution in the Nepalese context and to identify areas for potential improvement. This will be achieved through a structural analysis of both the interlocking brick system and the traditional burnt brick system. The study will examine the structural behaviour of these systems under conditions such as earthquakes, fire, and strong winds. Based on the findings, recommendations for improving the structural system will be provided.
The analysis will draw on real projects and experimental data gathered by BUN. The outcomes of this work will help validate and enhance the quality of the interlocking brick structural system, ultimately enabling BUN to provide safe, affordable homes to more people.
Conditions:
The scope can be adapted to be either a Master or a Bachelor thesis with one or two students.
Start: Spring 2025. Apply latest October 2024
Location: The work can be done at BUN, Katmandu, Nepal or in Sweden.
Questions?
We are reviewing applications continuously. For further information or questions please contact: Ashish Maharjan who is based at BUN in Nepal.
Contact can be taken with Linn Bogren who finished a study on brick strength optimisation based on water content and compression in 2024. Also take part of her Travel dairy.
You can also contact Henrik Gustavsson project manager for EWB - BUN cooperation and Raine Isaksson Associate professor in Quality Management and EWB member working actively with BUN.

Volunteer
We have a passionate and experienced volunteer network of professionals and students who help make a difference and influence our work. Explore our volunteer opportunities and see how you can contribute with your range of skills, experience and knowledge directly into our activities. There is no requirement for an engineering degree, everyone is needed, and all are welcome. -
Be part of inspiring children
Sweden currently has a shortage of engineers, a profession that historically has been a very homogenous group. Because of this, EWB-SWE inform and inspire children to seek an education in engineering or technology. This is accomplished by assisting students with their studies, acting as role-models, and showing a non-conventional perspective on science, technology and engineering. -
Personal development
Develop your leadership and technology skills by participating in the seminars and activities we organize. -
Be part of our network
By getting involved, you become part of an extensive network of talented people. We are not just engineers - everyone is needed, and everyone is welcome! We are located all over Sweden with our groups in 8 different cities.
