Research: Building capacities & creating communities: Towards Multi-sector initiative in Urban Slums of Bangladesh
Task: Conduct detail physical survey of Slums around Bangladesh and Make recommendation for future intervention for BRAC Development Institute.survey include mapping on Infrastructure and service delivery, such as drainage, roads, water supply, streets, homestead detail & its functional arrangement with construction technique.
Background:
BDI’s Urban Poverty research cell is on the verge of rolling out pilot initiatives in five secondary towns -Dhaka, Rajshahi, Faridpur, Mymensingh, Bhairab, and Khulna, with an aim to instigate a comprehensive, multi-sector upgrade of urban slums, focusing on seven major themes - tenure security and land entitlement, livelihood strategy development and access to finance, health services, schooling and child labor, access to basic utilities, disaster preparedness and climate change and community mobilization.
The action research tried to address the varied and multi-faceted dimensions of urban poverty and find and implement innovative ways to climate-proof each of these dimensions. It sought to address, inter alia, the following:
Infrastructure and service delivery, such as drainage, roads, water supply, street lighting, and so on
Access to finance and livelihood opportunities
Housing and tenancy rights
Governance
Access to services, such as health, schooling, etc
Resilience and adaptation to climate change
Insecurity and violence, especially gender violence
Strengthen individual, institutional, and community capacity and empowerment
Build and maintain better lives and futures
Identify local political champions
Draw good practice lessons that can be used for future scaling up
The research, carried out in selected slums in metropolitan cities and secondary towns in Bangladesh, with a sample size of 300-500 households.

Compassion for Migrant Children (CMC) is a nonprofit organization that helps China’s urban migrant children, primarily through offering social and educational programs. This organization strategically builds community centers in the heart of migrant neighborhoods where they offer programs for migrant children and their family. CMC is working with Architecture For Humanity (AFH)-Shanghai Chapter to put up a community center in Beijing which will be the first modular/mobile container center even though they’ve opened 7 community centers in migrant slums in China and Nepal. Architecture for Humanity is another non-profit organization that consists of network of professionals who are willing to lend time, design service, expertise to help those who would not otherwise be able to afford their services and thus bring design, construction and development services where they are most critically needed. This organization has various chapters around the world through which they operate their activities.
Now, CMC is interested to open a similar community center made from customized container for the migrant children and their communities in Dhaka. In this connection, they have contacted Architecture For Humanity Dhaka chapter. According to our first meeting with the Chairperson of Architecture Department, BRAC University, Dr. Fuad H. Mallick and also a senior advisor of AFH-Dhaka chapter, we have some concern that the module that have been implemented at china may not be feasible at Bangladesh’s context. So we should first conduct a feasibility study in cooperation with the user group about the potential construction method for the possible community centre in Bangladesh. AFH-Dhaka sets out a partnership with CMC to conduct a research on the type and appropriateness of the facility. It particularly focuses on expert assessment for a cost-effective solution through survey, finding potential source and cost analysis of shipping container, communication with local metal workers for refurbishing the containers or find potential options other than shipping containers if the study reveals that they are not feasible. In the end, locate a probable community who would be willing to have a facility made from container which will be then monitored and evaluated over a period. Parameters for the required facility are quality, mobile, flexible, affordable, and scalable. final outcome will be a prototype design of CMC Community Cube for Bangladesh and help CMC to implement those community centre.
Compassion for Migrant Children has already launched the Community Cubes model in China, is currently setting it up in Nepal, and is expanding to Bangladesh now as well. CMC goal is to see 100 community centers opened around the globe.

Project Name: Life in 1.5’ x 30': Changing Semiotics of Urban Grey Space
>> Addressing the issue of Urban Grey Space with design and architecture<<
Project Type:
1) urban planning design strategy
4) interior design
6) architecture
7) other: hands-on demonstration project to introduce a new Protagonist of Urban planning issue
Project Mission/Goal:
1) Improve the human spirit of micro entrepreneurs
2) Increase awareness of the environment and address climate change
3) Respond to our growing need for hygiene, Energy and Economic development
4) Address humanitarian crises of informal micro entrepreneurs
5) Re-construct a new idea for urban planning issue.
6) Changing SEMIOTICS of urban unused spaces where one family can survive with better living condition and will be very meaningful for the micro entrepreneurs
7) Introduce a new form of urban citizenship
Project Description:
In the urban fabric, “Grey Spaces” occur in gaps of what is planned, controlled, financed by authorities or simply built by private developers in irregular or unplanned ways, occupying and setting up small businesses on land that has remained vacant for a long time or with poor accessibility or space used for dumping waste. Although, the arrangements are often legal or semi-legal but the enterprises produce and distribute legal goods and services. Hence the naming- the ‘Grey Space’. This particular issue is the result of changes in the worldwide economy. This is really about how to deal with globalization and the demands it puts on a city. Although these activities seem trivial, but what they show is a demand to use space, which can be seen as a new form of urban citizenship.
This movement is increasing every year but the respective authorities have turned a ‘blind eye’ to this growing problem. A widespread misconception exists against this particular economy, related to the underground. However, such attitude is no solution to this emerging problem, as various factors are involved and the problem seems to be worldwide. These grey spaces are growing and seem to be a permanent feature of a city. Factors acting as stimuli are: lack of enough modern job opportunities to absorb surplus labor; slow rate of economic growth or faster rate of population growth.
Grey spaces contain several forms and dimensions. Grey spaces are contingent in nature. However, in the face of uncertain economic and political conditions, these dynamic developments have an inherent power to change and adapt, for required investment is minimal and the shelters are responsive to local conditions.
An example of such a phenomenon is this project located at Mohakhali, in between two building with 1.5’ at the narrowest, 3.6’ at the widest and 30’ in length. The story of this grey space began when a 12 year old boy, ran off to the city from his hometown, for survival which is a common phenomenon of a developing nation. The living condition was very poor because of two solid walls on the longer directions making the interior space dark, gloomy and congested. Even then, people were living in this place for more then 15 years because they perceived several advantages, including economic incentives.
My intention was to create a new semiotics for these types of spaces where one family can survive with better living conditions and value will be added for the micro entrepreneurs. Connecting all the spaces both visually and physically broke the tunnel effect, allowing the space to flow- thus, giving a sense of a single space. Also ensuring natural light, ventilation, use of alternative energy (present energy crisis) makes the space more meaningful. The semiotic of the space is such that it not only denotes the functions but connotes symbols such as: home, a sense of belonging. Such notion has made many spectators to remark-‘Arey eta to ekta bari!’ (Wow! This is a two storied house!).
In order to return the lost green, a 1.5’X5’ of space was put aside but this decision was even more justified when a hidden talent of my client was revealed i.e. he can play three different instruments. Thus a space with a touch of green and water would surely increase his artistic ability apart from contributing to the local ecology! Although these people have been living as a parasite for all these years, it was my desire to let them have the technology of conserving energy i.e. a solar water heater. One other issue considered is rain water harvesting, which is done in a small scale to run a small aquarium. Lastly, lots of vibrant colors are used on the exterior, so that the colorful background, the vivid color of the products, the passersby wearing bright colors (as preferred by our society & culture) all forms an ever-changing, dynamic collage. Collected, recycled timbers, plywood panels, and bamboo mats from the students of architecture department are mainly used for this project. Corrugated roofing sheets and some metal angle are also collected from the surrounding area. In all aspects an attempt is made to free them from the oppositions imposed by the society, authority and to re-construct a whole new place with a new semiotics- which they can identify it as theirs without any fear or hesitation.
Despite the continuing debates about its development, it is increasingly being recognized as a key to promoting growth and/or reducing poverty. It provides income for the poor and a safety net in times of crisis. This small scale enterprise which thrives in these grey spaces contributes in the social process by increasing the interaction between people and using the urban unused spaces. Thus, making the neighborhood more attractive and also, redefining the public spaces, which are closely related to their activities. As a concluding remark I want to say “these occupants are actually helping to restructure and revitalize our cities and I don't think these spaces are dead, it’s just changing. They activate the dead spaces, and break down boundaries between the public and the private. The blurring of boundaries leads to new ways of conceptualizing these areas”.

architecture for humanity Dhaka,bangladesh is partnering with Jaago for their new prefabricated retractable classroom at Karail and Rayer bazar in dhaka. afhdhaka is introducing prefab bamboo classroom in Bangladesh through this project. Jaago foundation is a charitable organization who are providing english medium education to the street & slum children without any fees. check out our previous school at Karail slum for Jaago: http://dhaka.architectureforhumanity.org/projects/7932
With an understanding of Jaago’s fresh philosophical idea & its unique educational technique makes us to build a new kind of structure which suites with jaago’s creative thinking and helps to develop a better physiological development of student in a better educational environment enhance them to think out of the box. Within a limiting budget we have tried to bridge a gap between our educational environment of privileged student and unprivileged slum children through their classroom structure. Tried to find a new cost effective, environment friendly technique as an alternative beside our existing CI sheet, masonry & steel structure to build classroom that is being used today. We have started implementing with a promise not to exceed 500tk/sqft but by the time being we have found it hard to limit it within that as a first demonstration of this kind. Existing LGED two storied prototype school cost 900-1100tk/sqft around the country and our current typical construction cost masonry(900tk/sqft),steel(1300tk/sqft),Ci sheet with C.C or wooden post single storied(450tk/sqft). At rayer bazaar 2storied will cost 658tk/sqft. The required amount is below then any kind of 2storied structure around Dhaka city. But we believe in future implication we can able to reduce the cost more even below 550tk. The reason for current high cost was that As a result, a lot of issues, incidents have developed which were not foreseen and were beyond our control but eventually effected the construction time and expense.

logic behind material choice:
Bamboo has a great potential to solve the scarcity of sustainable building materials for high-end and affordable buildings in both urban as well as rural areas. In Bangladesh, around 70–80 percent rural village still depends on bamboo as building material. Mostly the sales of bamboo in urban areas are used in construction as scaffolding in and few handicraft and other enterprises buy directly from the traders. also bamboo material is a symbol of ultra poor across the mega city Dhaka. It is estimated that despite extensive traditional use and availability of bamboo in Bangladesh, the sector only contributes few percent to the national GDP. Current bamboo applications have failed to capture additional value for the urban people. Existing market for the panel based (engineered) bamboo housing is almost none in Bangladesh. Starting the new market for the panel based bamboo structure may take some time until people start accepting it this is one of the major reasons why use of bamboo in Bangladesh for commercial purposed other then scaffolding is nominal and untapped to it fullest. There is no doubt that with the growth of this industry in Bangladesh, we would be able to provide benefit to the thousands of farmers who are growing and selling bamboo for their livelihoods. Yet, farmers in Bangladesh have been unable to sell bamboo in commercial manner and fetch a reasonable price. Promotion of bamboo-engineered panel will consume an extensive amount bamboo resulting to commercialization of bamboo farming, processing /production and marketing. Development of this industry will help backward linkages with the rural areas and can established a viably supply chain with the existing or potential bamboo housing industries creating a sufficient demands for available raw bamboo. In this two school project we have tried to introduce bamboo panel surface along with recycled metal structural element which is available in Dhaka city.

The Luke water treatment plant with pure drinking water bottle and jar production facility, a custom-designed facility for a manufacturer, represents collaboration between a client and an architect in developing a spatial strategy that integrates production goals with the well-being of employees. Key design objectives focused on transparency & a single volume that makes full use of the site as well as the use of local materials like wood and bamboo, fully natural light & ventilation reduced energy use, and enhanced thermal performance. The architect responded with a single, large structure where administration and production spaces were integrated under one roof, breaking down hierarchies between front- and back-of-house functions. The wooden louvers with glass in southern and northern façade, as well as gardens give each user access to natural light and views of nature; the spaces also provide recreational areas for the workers on river side, Signalling a departure from the generally poor standards of places of work around Bangladeshi manufacturing sector. The Luke pure drinking water factory sets a new benchmark for the design and construction of factories that priorities architectural design and the comfort of the users without significant cost premiums. The result can shows possibilities with a strong business mandate that seeks to inspire other industrial persons to be more engaged and more passionate about the environment and the planet.
this particular project could become a model of small scale social business with a greater cause in mind to provide access of safe drinking water. it can be implemented anywhere and make access of safe drinking water to School & College student, different Health clinic, Hospital, Food stall & Offices with a nominal profit margin. afh-dhaka encourage this kind of private sector initiative to help build better future.

Project Description:
One of the wonderful qualities about Bangladeshi people is that they enjoy other people’s company, gossiping with family-members, friends or even strangers. Unfortunately with rapid urbanization, means of recreation have become quite limited which have also reduced social interactions. However, tea stalls or other such small food stalls, which are one kind of vending, have been attracting people of all ages, religions, class and upbringing, for a while. Though, unnoticed and often less appreciated but such stalls have been effectively creating public gathering spaces of different dimensions, types and forms for a long time which cannot be compared or even classified with any other public space seen anywhere else in the world. Ironically, these dynamic developments have evolved in the face of uncertain economic, political conditions and growing problems such as rapid urbanization, poverty, lack of employment etc.
In their own way, they have given a wonderful solution for the economic development not only for our country but also for similar situations that persists all over the world. They not only have ensured employment opportunities for the poor but also fulfill the demand of lower income group and contribute to the overall economy. Saves time and energy consumption from the customer’s point of view as they are within easy reach of their home or office. Also there is no gender biasness between men and women since all of them are engaged in these activities. However in order to do that, they have occupied and established their own business on land that has remained vacant for a very long time or with poor accessibility or just beside the road with moving character. So although they have shown a demand to use space but since is it done in an illegal way, they often face eviction. Nonetheless, vending is no trivial matter. They might seem like a minority but it is rather a huge sector. Therefore time has come to seriously deal with this issue.
In spite of being ignored and despised by many, this sector was found to have enormous potentials. Close observation revealed that they have the inherent power to fold and unfold in accordance to changing political conditions. Also they have the ability to change and adapt, for their investment is minimal. In other words, these architecture and urbanisms of “necessity” operates with extremely limited material conditions that challenge the professionals such as planners and architects. Inspired by their indigenous knowledge in utilization of space, the design concept of-maximum utilization of minimum space was derived. So the idea formulated was that of a structure, retractable in character, i.e., it can be folded to form a compact structure. Also, based on their ergonomics, energy efficiency, a low-cost structure was to be designed for the BRAC TARC as an experiment that will be affordable by these vendors.
The intention of this experimental project was to demonstrate a possible solution of how different mechanisms can be integrated under a single system/unit which not only will minimize the cost but make it possible those people who are engaged in this profession to earn double then their previous income. Further study on this issue revealed some interesting facts, which are:
1. About 1 million vendors spend 20million Euro/month for making Tea. If this fuel could be reduced then their monthly income will increase by the same amount. 2. These 1 million vendors can reduce 1100 ton carbon emission per month for making Tea by reducing their fuel use. 3. Single Pop-corn machine utilizes 1300w/h of electricity. If Bio-gas is used to run1million machine then 13000mw/h of energy could be saved.
Therefore an attempt was made to make use of renewable energy instead of using natural fuel, coal etc. making it unique in terms of environmental sustainability for this sector. Although it meant that the initial investment will be double the previous one but in the long run the entrepreneurs will be the gainer since it would reduce the monthly fuel consumption. Also materials to be used are decided to be either recycled or sustainable in nature. Later wood was chosen as the construction material. Thus, although further improvement will be required for long term operation and system efficiency but the development progress are in initial stage. Micro enterprises have a huge prospect for a developing nation like ours and this project represents the present time and acknowledges the forces acting upon the urban condition. The focus of this project was how the very existence of this informal sector has been threatened. They have been thrown apart and discarded like garbage yet they continue to thrive, fulfilling the basic necessities of our lives and most importantly they contribute to about 60% of a developing nation’s GDP. This module, probably the first mobile vending system in the world makes use of alternative energy and other innovative technology. Also an attempt is made to free them from the oppositions imposed by the society, authority and re-construct a new idea for urban planning issue- which they can identify it as theirs without any fear or hesitation. It can be considered as a great introduction for the development of billions of micro entrepreneurs both within our country and outside, since vending is an integral part of urban fabric that cannot be ignored nor eliminated. The only remaining to do then is to relocate them or legalize them at certain part of urban areas- so that they can grow in a controlled and planned way.

Development Progress:
MOTOR : conventionally used motor in pop-corn making machine is 60 watt (car wiper). It is being modified using gear motor of only 1 watt x 12 in terms of watt hour energy saved (60watt x 3hrs =180 w-h)-(1 watt x 3hrs =3w-h ) =177 watt- hr.
BATTERY CHARGING : That motor is driven by a battery charging from AC 220V. The developed motor is driven by a DC 12V battery which is being charged by a 10watt Solar Panel during day light.
LIGHTING : In conventional system Hajak light or 60 watt filament bulb was used but in the developed system only two 3watt LED light was used and that will be run by same Solar charged battery.
SOLAR OVEN : Conventionally the oven was heated by a 60watt filament bulb but in the developed model a Solar Oven is used to keep the food hot ( 50-70’C). There is no use of conventional energy.
SOLAR WATER HEATER : conventionally for hot water , a burner is used to heat the water up to 80’C for tea making. In the developed system a solar water heater is used where we can get preheated water up to 60’C. So we only need to increase 20’C temp of water. That makes 60% energy saving in heating of water.
BURNER : The improved burner is used that can be operated by Bio-gas and because of special nozzle the gas use efficiency is also improved.
WATER RECYCLING SYSTEM : In the developed system the water that is being used for washing cup, tray etc can be recycled by using a simple filtration system ( using sand and stone layer)
WASTE COLLECTOR : In the developed system there is a integrated waste collector.
Note: This is a demonstration module of one typology without living facilities, which is an outcome of my Undergraduate Thesis on: Livelihood of Urban Grey space and how we can revitalize this enterprises as a protagonist of Urban dynamics who consider to be a new Urban citizenship also who helps to generate a new form of Public sphere.
