  • Cyclone Aidr caused massive damage to housing – some 1.5 million homes were either destroyed or damaged. UNDP, during the emergency phase, worked close with IFRC who was coordinating emergency shelter. Given this, and our role as coordinator of the Early Recovery Cluster we stepped in with the support of DFID and utilizing our own resources to provide what we call ‘Core Family Shelter.
  • Total Phase I : 9,145 (During April to October 2008), 13 UNDP NGO partner. Following a recovery assessment, one year on, it was found that some 150,000 plus vulnerable families were still in need. Total Phase II: 6,597 (During Oct 2009 to May 2010), 4 contractors by ITB, supervised by BETS Consultant.
  • Total plinth Area 150 sft (10’ x 15’), 6 no's RCC Columns with Bamboo Mat, 5” Brick retaining wall for Plinth, Wooden Truss Frame, 45 mm CI sheet for roof, wooden door/ window , Cost – BDT 72, 000 (USD 1,000 ) per unit, 9,145 built from April to October 2008 through NGOs.
  • - Context: GoB seeking additional support in shelter reconstruction…
  • Plinth area = 150 sft (15’ x 10’) + mezzanine floor 75 sft. Reinforced brick masonry, Steel Roof Truss, Color coated Tin Sheet, wooden frame door/window, wooden M. Floor.
  • Total Ht – 13’ 4”, 6’ upto Lintel, M floor over Lintel in one half.
  • Shallow Foundation of Brick masonry Anchor rod for Truss embedded in it. Bottom width of Foundation 25”.
  • Anchored Roof Truss to Foundation, angled at less than 30 degrees.
  • Shallow foundation of brick masonry anchor with rod truss embedded in it. Bottom width of Foundation 25”.
  • Identified and confirmed according to the National ID Card
  • 1 inch sand followed by Polythene layer underneath the foundation to protect damping. Needs 1 Day to complete the excavation by a group of 4 labors
  • Need App. 3 Days to complete this work by a group of 5 labors ( 2 Masson + 3 Helper)
  • Need App. 3 Days to complete this work by a group of 5 labors ( 2 Masson + 3 Helper)
  • App. 5 more Days to complete the Work up to this level by a group of 5 Labors (2 Masson + 3 Helper)

  • Door /window frame, Ladder preparation and then treatment and then transferred to houses.
  • 1 Day for Tin (Roof) setting and 6 days for Door Window setting.
  • Approximately 30 days need to ready the shelter for substantially completed
  • A COMPLETE QUALITY MANAGEMENT PROCESS WHICH INCORPORATED INTERNATIONAL HEALTH STANDARDS AND PROCEDURES WAS FOLLOWED.
  • Inexperienced contractors for this type of scattered work Lack of skilled labour locally aviable Remote areas, limited access – while there some grouping of unit, we more or less had 6,000 plus separate sites Early monsoon – caused delays Non availability of materials locally Land tenure issues - Local Dispute, missing Papers, Duplication of listing
  • Approximate unit cost is USD 1,400 Labour Cost is about 14%
  • - Because of the labour

UNDP's core family shelter design UNDP's core family shelter design Presentation Transcript

  • INNOVATIONS IN HOUSING DESIGN & COMMUNITY PARTICIPATION UNDP APPROACH FOLLOWING CYCLONE SIDR STEVEN GOLDFINCH PROGRAMME SPECIALIST UNDP BANGLADESH
  • WHY UNDP?
    • No national standard / approach to post-disaster shelter
    • Massive unmet need
    • Global mandate viz. Early Recovery
    • Scope to augment national effort
    • PRINCIPLES
    • Build back better
    • Drawing on risk reduction ‘1 is for 7’
    • Incremental model, with safety at the core
  •  
  • UNDP’S CFS PROGRAMME (1ST PHASE)
  • LIMITATIONS OF PHASE-I CONSTRUCTION
    • Core concept was good, but:
      • Beneficiary dissatisfaction over bamboo matting
      • Concern for environmental preservation / minimizing effect on deforestation
      • Disaster risk reduction features could be stronger
      • Additional durability could be achieved
    • Problems with NGO partners reaching standards
  • ENGAGING WITH THE COMMUNITY: PHASE II APPROACH
    • Goal: To promote self-reliance and empowerment of the community as they work to get back on their own feet.
    • Feedback from Phase I and consultation with communities
      • Participating in construction
        • Promoting Gender Equity
  • PRINCIPLE DESIGN CONSIDERATIONS: PHASE II
    • PRINCIPLE DESIGN CONSIDERATIONS:
    • SAFETY RESILIENCE TRADITION
    • DESIGN OBJECTIVES
    • STRUCTURAL SAFETY
    • PSYCHOLOGICAL SAFETY
    • CYCLONE RESILIENCE
    • DUPLICABLE
    • INCREMENTAL ASSET
    • DIGNITY & PRIDE

    • RESILIENCE FEATURES
    • ABLE TO WITHSTAND UP TO CATEGORY 4 CYCLONES
    • CONFORMS TO MINIMUM STANDARDS ENDORSED BY THE DISASTER MANAGEMENT BUREAU.
    ANCHORED ROOF ROOF IS ANCHORED TO FOUNDATION AND ANGLED AT LESS THAN 30 DEGREES, PREVENTING THE ROOF FROM BEING BLOWN OFF BY STRONG WINDS.
  • RESILIENCE FEATURES DOORS AND WINDOWS AS THE WEAKEST PART OF THE BUILDING, WINDOWS AND DOORS HAVE A Z-SHAPED BRACING TO STRENGTHEN THEM. BRICK WALLS WATER PROOF, 10-INCH THICK BRICK WALLS ARE ALSO RESISTED AGAINST TIDAL SURGES BRICKS ARE NOT PLASTERED, ALLOWING THEM TO REMAIN POROUS. AIR AND MOISTURE CAN PASS THROUGH, THUS MINIMIZING CORROSION WHICH WILL WEAKEN THE BRICKS . FOUNDATION FOUNDATION DESIGNED WHICH CAN WITHSTAND CYCLONIC FORCES .
  • DESIGN FEATURES GIVES BENEFICIARIES THE OPTION OF INVESTING THEIR OWN RESOURCES TO ADDING LIVING SPACE AND FUNCTIONALITY FUTURE OPTIONS HOUSE CONSTRUCTED LEAVING THE EDGES ‘TOOTHED-END’, ALLOWING FUTURE EXTENSIONS TO BE BUILT TO THE CORE HOUSE.
  • DESIGN FEATURES
    • MEZZANINE FLOOR
    • WOMEN POINTED OUT THE NEED FOR MORE PRIVACY AND FLEXIBILITY IN USING THE LIVING SPACE.
    A MEZZANINE FLOOR PROVIDES EXTRA LIVING SPACE IN EACH UNIT IN TIMES OF FLOODING, THE FAMILY CAN SEEK SHELTER ON THE SECOND FLOOR AND PROTECT THEIR BELONGINGS. FLOOR IS MADE OF EITHER WOOD OR BAMBOO, SPECIALLY TREATED TO ENSURE THEY ARE PROTECTED AGAINST INSECTS AND SALINITY, INCREASING THE LIFESPAN OF THE BUILDING.
  • SPECIAL FEATURES
    • RAINWATER HARVESTING
        • GUTTERS ALONG THE ROOF ALLOWS FAMILIES TO COLLECT AND STORE RAINWATER FOR THEIR HOUSEHOLD USE.
        • COASTAL VILLAGES SUFFER FROM INCREASING SALINITY IN ITS WATER SUPPLY, RESULTING IN A LACK OF FRESH DRINKING WATER.
  • LOCAL RESOURCES ENSURING BUILDING MATERIALS WERE LOCALLY AVAILABLE AND OBTAINED, THUS ALSO SUPPORTING THE LOCAL ECONOMY. SPECIAL FEATURES
    • ESCAPE HATCH
      • .
    THE WINDOW ON THE MEZZANINE FLOOR PROVIDES VENTILATION, AND IS ALSO AN ESCAPE HATCH TO THE ROOF IN TIMES OF FLOODING.

  • PROCESS FOLLOWED International Tender Bidding Selection of beneficiaries RFP RFQ Project implementation Issuance of contract Final selection of the Contractors Technical evaluation Co-ordination Evaluation Monitoring Substantial completion Handed-over to beneficiaries 6 Month DLP Final completion
  • CONSTRAINTS DURING IMPLEMENTATION
    • INEXPERIENCED CONTRACTORS
    • LACK OF SKILLED LABOUR
    • REMOTE AREAS, LIMITED ACCESS
    • EARLY MONSOON
    • NON AVAILABILITY OF MATERIALS
    • LAND TENURE ISSUES
  • COST BREAKDOWN
  • ECONOMIC IMPACT
    • APPROXIMATELY 30 MILLION BRICKS
      • 130,000 CEMENTS BAGS
        • OTHER ASSOCIATED LARGE SCALE CONSTRUCTION MATERIALS SUCH AS STEEL AND TIMBER
    THIS PROJECT CREATED MORE THAN 900,000 LABOUR DAYS OF EMPLOYMENT OPPORTUNITIES OF WHICH APPROXIMATELY 500,000 LABOUR DAYS WERE BENEFICIARIES
