“ARCHITECTES DES RISQUES MAJEURS” ASSOCIATION
The «Architectes des Risques Majeurs» association (ARM), founded in March 2016 by architects and engineers who have attended a post-master degree Architecture & Major Hazards at ENSA Paris Belleville, is aiming to become a place for meeting, studying, proposing and acting around the notions of major hazards, architecture and urbanism. It proposes to: - Promote the integration of major hazards in architecture to professionals and other publics (town representatives, schoolchildren, residents, architectural students, etc.) through exhibitions, seminars, workshops, trips, newsletters… And thus, to ensure a networking between specialized architects-students and professionals. - Sensitize the institutional actors on the need to integrate the architectural and urban aspects in the territory planning and the design of buildings in risky zones. - Intervene in prevention, post-disaster and development phases to integrate the notion of risk culture, from the territorial scale to the international level so that the management of major hazards is assured in the long term. As a founding member and president of the association for a period of three years, I realized that there was a demand for reflection, intervention and innovation in risky zones projects. We work on multiscalar projects, humanitarian actions and assemble multidisciplinary teams so architecture is as precise as possible in these particularly complex contexts.

Context: Nepal, on the edge of India and China, is the third poorest country in Asia. In April and May 2015, the earth shook several times, weakening many homes and erasing a part of Nepalese heritage. A year and a half after these events and emergency actions by international NGOs, we went to Dolakha region, 20 minutes far from Kathmandu by helicopter, or 13 hours by coach because of the weakness of the infrastructures. The country is also suffering from heavy floods during the monsoon from June to September, as well as frequent landslides. The life expectancy rate of Nepalese does not reach 68 years. Access to care in high altitudes and pollution are an integral part of national problems. The international NGO Architecture&Development has proposed to us to carry out a technical and social in situ diagnosis in order to participate in the realization of a technical charter requested by the National Reconstruction Authority (NRA) created in January 2016 by the Government of Nepal. Indeed, the government decided to provide installment to each family affected by the earthquake for the construction of a new house. The communist party wants
to distribute financial aid fairly in three stages of construction: foundations, walls at the height of the sill and roof. At the end of these phases, mandated engineers validate the conformity of the production thanks to the technical guideline published by the NRA.
Hay stock
On-site, that theory is hardly visible. Too many households need financial resources and workers often misinterpret the new regulations. Cooperatives and associations are created by the inhabitants to ensure their survival and use to work with international NGOs.
Goat shelter
For a week, we conducted a multitude of interviews with the inhabitants of two villages in the region of Dolakha and recorded 35 houses – destroyed traditional houses and CGI shelters equipments and infrastructures. We have also listed the water and electricity networks with Geographic Information System. The challenge of our work has been to propose a convincing methodology to maximize the reusable structure and materials of a private school with a stone basement and RCC post and beams on the second floor which suffered a lot the earthquakes.

Security - The connection between the framework of the wooden passageway and the wall is dangerous. Weak connection. - Existing stairs/ladder
Structural Context: In every hamlet, open-covered structures called “pati” traditionally enables social community activities. They are used to gather people in rural areas. They should be reinforced to provide security to the citizens. They will become refuge areas in case of natural disaster.
6
Maina Pokhari private school has been seen as an illustration of these refuge areas. In case of earthquake or flood crisis, the signal alert is emitted from the refuge area. The bigger part of the existing structure has been kept, as far as the structural strength was ensured. Indeed, the most you modify an existing structure, the most it could be weakened. The existing RCC slab of the second floor is half the weight of the stone walls. It is able to support the RCC columns and a new floor and framework. However, the internal stone walls are in very bad shape, one of them is totally collapsed. The South-West angle on the groundfloor has too many cracks and needs to be completely replaced. The structure of the RCC staircase doesn’t stand on proper foundations and its location is not the best one to ensure evacuation in case of fire. The building is disconnected from the embankment in order to have two different resonance frequencies in case of earthquake. The flow around the building would also be smoother. Here is the statement of the building after having removed all the defective materials. We may notice that the structure is not totally regular but still displays a generous open space.

TOWARDS A REGULATED RISK TERRITORY Collaborative approach in the commune of Luz-Saint-Sauveur Partnership between ARM and CivicWise associations DSA Risques Majeurs de l’ENSA Paris Belleville E. Pierre, D. Lerche, P. Chombart de Lauwe 2015-2016

Context: The commune of Luz-Saint-Sauveur is located in the hollow of a valley whose highest point, at the level of Luz-Ardiden ski station, is at an altitude of 2500m. The municipality is exposed to several types of flood risks (rising groundwater, submersible zones by overflowing streams and runoff ) as well as seismic risk, avalanche, landslide, blocks falling and liquefaction. Indeed, because of its geography, the commune suffers the steep slopes witch induce large flow corridors, defined by the ridge lines. The Bastan, the Yse and the Gave de Gavarnie Rivers allow to absorb a part of these flows but the complete management of the flood risk is complex. These three torrents are conducive to overflows when several factors are encountered. During the flood of 2013 for instance, the municipality had undergone heavy rainfall in early spring as well as significant snow melt following the first heat after a snowy winter. Since then, the municipality has set up a Communal Safeguard Plan, which is currently being updated. Concept: The objective of the project was to integrate the management of these risks with strong urban intentions to reveal the identity of the districts and to revitalize an attractive center between Luz-
Saint-Sauveur and Esquièze, the neighboring municipality, on the north bank of the Bastan River. A network of places has been developed around a requalification of each use, soil treatments and network of vehicles and pedestrians. Indeed, a new access near the current road crossing allows users to live, buy and work in Luz-Saint-Sauveur, rather than just crossing this village whose assets are hardly visible from the main roads. Two guiding threads have been developed to provide a common language, necessary for the discovery of the territory: the reuse of the materials available in the torrents bed after the floods in gabions and the introduction of water in urbanized areas, as a factor of conviviality and also to mark the flood risk in the daily life of the inhabitants. After making a careful diagnosis of the structural condition of the buildings on several blocks, different grades of priority have been defined for the reinforcement and in agreement with the major urban intentions.
Luz-Saint-Sauveur 2000-2005
Upstream, predictable volumes and speeds of water in case of high flood have been channeled through the development of a succession of infrastructures. In the village center and along the banks in its proximity, landscaping has been designed both for the security of habitats and the heritage, and to invite to the discovery of the territory and to reveal the existing potentials of the municipality.

Synthesis concerning earthquake risk
One of the aims of the ARM association is to sensitize institutional actors on the need to integrate architectural and preventive aspects in any type of spatial planning in risk zones. During a week-long residence as assistants of the steering committee for the Bastan River banks redevelopment, we communicated about risks prevention by going to meet the inhabitants during several collective events (market, sheep festival) and by elaborating a questionnaire published on the website and the Facebook page of the town hall, aiming to sensitize and to get the population involved in the project, from planning to design and on the construction site.
10
Coming from these actions, we prepared a document that provides methodological support for the drafting of the design brief, with the objective to integrate the concept of flood risk into all the project phases. The principle of a collaborative approach has been proposed. Indeed, it seems essential to us that the inhabitants are in the center of any urban project. It is also the opportunity for architect to introduce the concept of prevention and risk culture into the project. By participating in such a project, the citizen would take responsibility and learn naturally about the actions that can save him in case of disaster and about the technics that would enable him to improve his environment.

BACK TO THE SOURCES IN THE HEYANG VALLEY Laureate of the second prize Project 8-Mutations department B.-J. Hubert et G. Bignier Realization with G. Coupez et C. Varin 2013-2014

Context: After a four-day workshop with students of the China Academy or Art and two weeks of travel in Beijing, Shanghai, Hangzhou and the heart of the Heyang Valley, we participated in a contest launched in 2015 by the Zhejiang Province Government (East of China) and organized by the architect Wang Shu (Pritzker Prize 2012). The competition was entitled “Beautiful habitat, Outstanding Village Housing Design Contest”. The government’s goal is nowadays to promote new construction standards, to establish a waste collection system, wastewater treatment plants and collective transport. Local authorities are setting up electrical communication in the villages. Up to then the urbanization was developing without any regulation. Houses have neither running water nor drinking water. Furthermore, the Heyang Valley goes through speculations due to the tourism development. Indeed the well-off and middle classes aim to return to a healthy environment and to a familial atmosphere. Unscrupulous promoters multiply heavy transformations of traditional houses into charming hotels: phenomenon involving the expulsion of villagers and disfigurement of the original landscape.

Master plan of the development of the Valley
Concept : Planning broadly the valley development may prevent ecological and social risks. That is also a solution to revitalize the Heyang Valley: rehabilitation of the existing buildings, sanitization of wasteways, highlighting the landscape, building with local materials, to get a «village-city» of 20, 000 inhabitants, as wishes by Wang Shu. Clear water, rainwater and water from the reservoir are treated thanks to several systems to get as clean water as the different uses require: aquaponics, phytoremediation beddings and water treatment plants are located on the edges of fields and roads, around and in the center of houses and at the «village-city» way-out. The inhabitatnts are brought to follow the course of the water: enter the building along the visible water, live spaces organized through good quality water corresponding to their needs, maintain their garden which takes part in the ecological treatment of the recovered rainwater. 13 Topography of the Heyang Valley

The households are all composed of one or several patios which bring lighting and cooling. The access to the apartments is from collective passageways which link housing to shops. They are protected from rainwater thanks to an overhang on the roof. That promenade encourages people to take a walk on the different floors open to the landscape with cultivated fields to the East, the water movement and first and foremost meet with neighbors up.

That promenade encourages people to take a walk on the different floors open to the landscape with cultivated fields to the East, the water movement and first and foremost meet with neighbors up. Bamboo, concrete and rammed earth are also linked to water as a natural resource. Their physical properties define the architecture’s morphology, organization and aesthetic. Light and resistant, bamboo is also antifungal, antiseptic and impermeable thanks to lime water. Moreover it is an unlimited resource thanks to its quick growth. Lime water residues take part in composting within each household. The concrete located in the bedrock leads to ensure a distance with water and the waterproofness of the structure. Rammed earth is the load-bearing material; it brings a natural and efficient insulation and a humidity control. Rammed earth provides also a strong link with the existing and ancestral construction techniques.

Context: Loches City, located south of the CentreVal de Loire region, is a Ville d’Art et d’Histoire1 and one of the Plus Beaux Détours de France2. Since the 1980s, the demographic growth of Loches has slowed, especially following the cessation of Paris mushrooms production. Due to the arrival of rural elderlies who want to approach the nearby amenities, the population is aging. People from Tours City, the prefecture, who wish to acquire an affordable property close to nature also fuels this new population in Loches.

Phase of the intervention led in the design project
Urban scale
There are natural boundaries, such as the topography, the nature of the soil and a submersible zone near Indre river. Artificial boundaries established by humans like infrastructure, the Local Town Planning, the Safeguarding and Valorisation Plan have emphasized the trend of suburbanization. That creates a proliferation of individual houses which consume space and limit interactions between the inhabitants.
18
Over the years, city dwellers thus seem to have turned away from old heritage. The town of Loches wishes to attract a young population to ensure the prosperity of the city center and its economy. But the dynamism of the city depends mainly on brief historical tourism. Therefore for other activities, local life is particularly dependent on Tours City. Concept : The purpose is to inflect these trends by taking advantage of existing potentials and taking into account comments gathered from the stakeholders of the city. Assuming an evolution from the past to new uses, the project proposes a new vision of the local architecture. By means of discrete or assumed interventions on different typologies, it presents a strategy in order to achieve a well-reasoned development of Loches City.

1_DISCRETE AND ONE-TIME INTERVENTIONS IN PROTECTED AREA
1 Press house, access to the housing on the 2nd floor from the street
2_ENHANCED URBANISM AND ARCHITECTURE IN DETACHED HOUSE AREA
About thirty dwellings in the city center are vacant for several reasons: -Housing units on the second floor above the shops are inaccessible from the street. Originally, most of the storekeepers lived above their trade. Over time, businesses have invaded the facades on the ground floor, at the cost of circulations. -Lake of maintenance because of the high cost of renovation of old buildings in the conservation area managed by specialized companies. -Owners do not live in Loches City but in Tours or Paris. -Living spaces are too small: traders therefore use the floors for storage. Indeed the floors are included in the price of housing leases since they have no independent access.
Agricultural or free lands are gradually eroded by the multiplication of detached housing estate. Little surface is devoted to the garage for private cars across the city. This is why cars are parked directly in front of the houses and the collective space and limit interactions between the residents. As a result, many districts are outlying from the city center, mainly residential and without the benefits of the countryside.

Thus the expansion of the city is directed out of town and even beyond the ring road. That phenomenon accentuates the need to use a private vehicule to reach the different features of the city: there is no regular public transport in the city.

Architectiral scale 1
The project deals with interventions that can be put into three registers that could be called three generics. The first one concerns rehabilitation of abandoned buildings. Indeed, one of the factors of the declining of small towns is the fact that these cities are deprived of public services. The slogan of this type of intervention could be to ensure continuity by assuming rupture. This is what would give adapted qualities in a protected area, through an Architectural Charter.
20
The second register comes from an observation of the ancient urban fabric and acts as acupuncture interventions. By accumulating microsurgery actions on existing typologies, a new impulse, a new energy could be given thanks to contemporary tools.

The third register corresponds to classical housing. We can imagine that we could increase several blocks even densify them to respond to demographic growth. Program, accessibility, adjustment to ways of living, community life, density. These topics, applied to two sites with standard contexts, tried to respond to the different issues of the study area: the aging population, the escheat of the historic center, encroach on farmland bit by bit around and beyond the city limits by multiplying detached houses and by increasing the use of private cars. That type of analysis and interventions at architectural scale could be applied to the territory scale. An attempt to “Horizon 2030 Local Urbanism Plan� has been developed to respond to the statistics which provide a demographic growth of 200 000 inhabitants in Centre-Val de Loire region.

COMPARATIVE APPROACH of wood assembly joints for wooden laminated beams and panels 5th year report - «Transition(s)» department R. Leroy 2013-2014 Context:
22
According to the Ministry of Ecology, Energy, Sustainable Development and Territory Planning, the sector of construction represents 42% of energy consumption in France – construction and exploiting of buildings. In the context of the Kyoto Protocol, industrialized countries have pledged to reduce their emissions. Wood therefore presents significant potential to save energy. The decree of the Wood Construction Environment Plan aims to promote the use of wood in construction. One may wonders how how such a political goal may apply at the urban-architectural scale.
Microscopic observation of the phenomenon of thermo-welding Images taken at «Ponts et Chaussées» School
Excessive carbonization

Realization of conical bearings with a wood lathe
The exploitation, processing and implementation of wood require much less power than for other structural materials. As a result, the construction of a building in wood structure consumes two to three times less energy.
Here is the essential role of the architect. What can be the improvements in the timber industry for wood architecture to get it greener? Can wood be used in any climatic, geological, structural, programmatic, economic conditions? I also wanted to test one of these innovative and promising assembly techniques. Through experimentation, the goal is to being a research-engineer. I chose the thermo-weld: a 100% wood connection which allows a 20% gain of resistance compared to a traditional pegging. It seemed interesting to acquire a simple implementation, controllable by all and firstly by a student in architecture.
23
Even if these techniques are efficient, may they be used to improve thermic insulation of buildings? To densify the city? What are the architectural potentials of thermo-welded joints?
Realization of testing pieces
Concept: New types of innovative joints are currently in research phase in laboratories in private engineering or business schools. I thus made an inventory of these techniques and compared traditional joints via shear strength tests.
