    The profession of construction project planning is facing new challenges due to the
    complexity in architectural and engineering design, short deadlines, enormous
    pressure from clients, and the need to build faster. Such challenges become
    problematic especially in large projects where construction operations shape
    complex spaces. The problem in current project planning techniques is that they do
    not include spatial requirements of construction operations as a resource in their
    schedules. In this paper, we report on the recent development of Site-PECASO
    model (Patterns Execution and Critical Assessment of Spatial Organisation) as part
    of our on-going research. The technique of ‘registering’ space can be divided into
    three parts: Extraction of geometrical information from CAD model; Application of
    space operation module developed in VBA; and structuring of CAD physical
    components in a hierarchy of Space Breakdown Structure (SBS) model. We show
    the current state of implementation and demonstrate the integration between the
    3D-CAD model and the construction operations in the project schedule. In this
    context, Site-PECASO will provide project planners with a product-oriented
    simulation tool that highlights spatial clashes and interference between
    construction operations in real-time 4D (3D + time) environment.
