Shelter Meaning of transitional shelter

� Take-home messageTransitional shelter is not a Product = a Process, a Phase

� Many options to provide transitional shelter



� Many options to provide transitional sheltere.g. appropriate construction material, tools and fixings, cash and/or vouchers, host families, technical guidance and training, etc.

� One of the options: transitional shelter product

Shelter Transitional shelter as a product

“Rapid, post disaster household shelters made from materials that can be upgraded or re-used in more permanent structures, or that can be relocated from temporary sites to permanent locations. They are



temporary sites to permanent locations. They are designed to facilitate the transition by affected

populations to more durable shelter.”

ShelterChallenge of designing transitional shelters



ShelterVietnam case studies - Two contexts with Similarities and Differences

� Recurrent floods

� Deforestation

Poor construction standards

� Impact of disasters

� Houses typologies

----------------------------------------------------------------

Central Vietnam1998 – learning

South Vietnam2000 – Quick



� Poor construction standards

----------------------------------------------------------------

ShelterVietnam case studies - Two contexts Natural disasters

Central Vietnam:

Flash flood, strong winds, bankerosion, landslide

----------------------------------------------------------------

South Vietnam:

Slow rising waters during fewmonths, bank erosion

Shelter Vietnam case studies - Two contexts Houses typologies

Precarious houses

• Dimensions 7x 5 m

• 2 or 4 slopes



South Vietnam

Central Vietnam

• 2 or 4 slopes

• Bamboo/timber or concrete poles (CV ) for the structure

• Straw or CGI for the roof

•Annexes for services

ShelterBackgroundTraditional practices in disaster responses

� Limited resources (financial, HR with shelter expertise)



� NS involved through deployment of volunteers –Capacity building/training

� Relief activities with distribution of NFIs including CGI

ShelterOther responseInclude long term disaster preparedness and risk reduction components

� Provide a strong / sustainable structure resistant to current natural disasters

� Develop a progressive design that allows extensions and adaptations from emergency shelter response to a more permanent dwelling



� Choice of a simple technique that allows rapid set-up with basic tools and instructions

� Choice of material available in the region – limiting the deforestation

� Facilitate copying mechanisms

� Looks “basic” to void “jealousy” in community/cost in strength

ShelterDesign Two designs reflecting two contexts

- Galvanised steel frame braced and assembled by bolds and nuts

- Typhoon résistant roof withstand winds of 150 km / h

- A mezzanine that can



- A mezzanine that can accommodate a load of 2 tons

- Concrete foundation

- Openings every 50cm and profiles allowing various cladding materials and extensions

ShelterEvaluation after 7 yearsAdvantages and Disadvantages

� A rapid response with a product that can be easily distributed and assembled

� Relatively low costs per unit (USD 500)

� Minor replication dues to the unfamiliarity of the steel construction technique

� A technique that not allows easy extensions – to connect local

----------------------------------------------------------------



500)

� A long term resistant design with low repair & maintenance costs

� Flexibility of the design given the chance for various adaptations according to needs and tastes

extensions – to connect local building materials to steel frame

� Absence of good insulation of the roof

� The poorest people needs assistance to “improve” the house and for economic independence

Shelter Some thoughtsHow to improve our collaboration?

• How to establish the right timing for intervention?

• How to raise awareness on steel structures?

• How to stimulate local economy/collateral/loans?

• How companies can support in designing (cultural as pect) and

testing (performance)?



testing (performance)?

• How to have affordable price in the steel products?

• For design flexibility purpose how to develop gener ic construction

items/spare parts specifications? Standards versus diversity

• How to develop connectors, to allow better extensio ns with local

construction materials?

• How to get assurance on quality/life span?

Shelter Questions ?
