Design Parameters

Scenario:  This year the competition will require students to design and build a full scale proto-type of a shelter that would be appropriate for response to an earthquake disaster in Pakistan, similar to the 2005 earthquake in Balakot, Pakistan.  Affected Pakistani families lost their homes and need transitional shelter.  The shelter should be designed to meet the needs of a typical Pakistani family who are looking for shelter that may be constructed on their own property or in areas designated by local officials for temporary relocation.  As much as possible, designs should take into account local conditions, specifically the environmental, social, cultural and religious needs of a family.  The shelters should be considered transitional or core shelters (rather than emergency response) so that the shelter has the capacity to be added to, upgraded, altered, and modified to meet the changing needs of a family that is anticipated to be displaced for a prolonged period.

Standards: Designs should meet Sphere Standards and other appropriate internationally accepted standards (located at http://www.sphereproject.org/).

Accommodation Requirements: The shelter design must:

  • Accommodate a family of 4 with a minimum allocation of 3.5 square meters of space per person
  • Height must allow standing head clearance of 2 meters for at least 70% of the floor space
  • Provide dignified accommodation for a family, with adequate flexibility to respond to social, cultural and religious requirements (e.g. the use of spaces by different genders and ages).
  • Shelter should take into account potential cultural considerations or sensitivities.
    • Note:   Shelter footprint must not exceed competition earthquake shake table sized at 16’ x 20’.

Physical Performance:

  • Versatile and responsive to the scenario environmental conditions that may vary geographically, seasonally and diurnally (from day to night) within the scenario area.
  • Provide protection from extremely hot summers, and cold and rainy winters.
  • Ability for floor covering to prevent conductive heat loss and exposure to dusty ground
  • Perform well structurally against:
  • Wind loads (withstand 75 km/hour wind)
  • Seismic loads, similar to withstand earthquake of same magnitude that devastated Haiti
    e.g. design according to seismic acceleration factor Ss of 1.24 and S1 of 0.56 - as per use in Haiti according to US earthquake codes ASCE 7-02
    • Versatility in design to allow adequate airflow for natural ventilation in hot climates is critical
    • Ability to retain heat due to significant changes in temperatures during day/night and summer/winter.
    • Can be erected in a variety of topographical and geological conditions – from sandy to rocky landscapes, flat or sloping
    • Must demonstrate that the structure is reusable (i.e. can be redeployed for another disaster).
    • Must be upgradeable to something more permanent by the shelter users, using local materials, techniques, and skills, as per transitional features mentioned above
    • Allow for grouping of structures for expansion or use for purposes other than habitation

Materiality, Cost-Effectiveness, Packaging and Transport:

  • Minimum lifespan of 1 year – longer is better
  • Cost-effective: $1500 or less to fabricate. Economy of scale during the production phase should be considered as vitally important. Teams must submit documentation to verify the cost of materials used in the shelter. Donated materials not priced will be assigned a cost by the judges.
  • A business case analysis should be completed to show the viability of mass manufacture of the shelters.  Format for the analysis is provided as a separate attachment.
  • Lightweight: Overall weight should be minimized; ideally no more than 200 kg per package to allow handling without equipment.
  • Easily stored and transported i.e. manufactured so that it can be flat-packed and fits into a standard 8’ x 40’ shipping container (note that the interior of an 8’ x 40’ shipping container is not exactly 8’ x 40’).
  • Packable for most efficient use of 8’ x 40’ shipping containers (i.e. packages should be designed to fit in shipping container with minimal wasted space).
  • Easy and rapid to assemble without technical experience. Assembly should be straightforward and require minimal manpower, non-electrical tools - that is, simple hand tools that are generally available around the world.
