    INTRODUCTION
    •Current “cast-in-place” construction used in the field
    since roman ages
    •Remains labour intense
    •Problems in the areas of productivity, quality, safety,
    and skilled labour shortages
    •To address these issues, various types of automation
    and robotic technologies have been proposed and
    implemented
    •Require a paradigm shift in process technology

    DEMAND FOR INNOVATION IN
    CONSTRUCTION TECHNIQUES

    4
    CURRENT CONSTRUCTION
    •Labor intensive
    •Slow
    •Dangerous
    •Corrupt
    •Over budget
    •Low work quality
    •Difficult to control

    CONTOUR CRAFTING(CC)

    6
    CC
    •Type of 3D printing technology
    •“Additive fabrication” technology
    •Building layer by layer
    •Combination of extrusion and filling
    •Uses CAD-CAM
    •Do automated
    plumbing, electrical
    network etc..

    CC -METHODOLOGY
    •Planning and optimisation
    •Defining tool path and nozzle control
    •Operational facts
    •Logistic issues
    •Environmental impact
    •Sustainability potential

    HOUSE BUILDING PROCESS
    Flattening of the surface

    Excavation of trenches for foundation

    CC runs on specially developed rails

    17
    Cross beam is provided to link the limbs

    The raw material is pumped using


    pipes
    18
    19
    As the concrete hardens fast , it
    provides the support for the other
    layer

    Window and ceilings are


    laid using robotic arms

    As the pre manufactured ceiling


    is being laid it offers surface roof

    ADVANTAGES OVER
    CONVENTIONAL METHODS
    The reduction of construction duration by
    Implementing contour crafting:

    STUDY CARRIED OUT BY :Carel M. Rouhana and Farook R. Hamzeh

    MODEL USED: single unit square shaped of size by EZStrobe

    METHOD OF CONSTRUCTION: conventional construction method


    and contour crafting
    RESULT

    duration of 29.54±0.065
    duration of 90.52±2.12 hours
    hours with a standard error
    with a standard error of 0.067
    of 0.002

    PORTION% CRAFTING
    1 20-25 FINANCING SHORT PROJECT LENGTH AND
    CONTROL OF TIME TO
    MARKET WILL DRAMATICALLY
    REDUCE THE COST.

    PROCESS.
    3 45-55 LABOR WILL BE SIGNIFICANTLY
    REDUCED

    STUDY CONDUCTED BY MR. BEHROKH KHOSHNEVIS 38


    COMPETITIVE ADVANTAGE

    39
    LIMITATIONS OF CC

    •Employment issues
    •Initial cost of machine is high
    •Foundation need to
    constructed conventionally
    •Not suitable for high rise
    buildings

    40
    CONCLUSION
    •Immediate application in low income housing
    •Emergency shelter construction
    • Little or no material waste
    •Construction of structures with exotic architectural
    designs
    •High speed and efficiency
    •Promising new method in construction industry
