    Abstract

    The complexity of construction projects makes site planning one of the most challenging tasks for project managers. During the last decades computing technology has been used for visualizing and anticipating future events. In this regard two principal methodologies have been applied for site layout: heuristic methods and mathematical methods. Moreover, resent technological development has made possible the analysis of dynamic site layout. Hereby, the state of the art encompasses the incorporation of graphical information and project schedules within the same virtual environment, known as 4D construction simulation.
    This tool allows visualising in advance 3D models of building components, and construction equipment and material throughout the duration of the project, thus enabling planers to evaluate construction methods, analyse project buildability and site space usage. However, the wide variety of construction materials, packaging methods and dimensions have been some of the reasons why these have been often left apart from 4D simulations. Thus, the effect of building material and its space requirement have been neglected.
    This research introduces a simplistic mathematical method for site layout, particularly focused on prediction and reduction of site space conflict by considering the area required for material stock for calculation of material delivery plans and optimisation of delivery batch sizes. Additionally, a set of tools that attempts to simplify the incorporation of construction material 3D models within 4D simulation is presented.
    The proposed method and developed system were tested in two stages: i) Code verification: a numerical analysis of twenty trial projects, which data was randomly generated. Ii) System validation: a graphical analysis of a hypothetical case of study (partly based on a real project data) through the use of 4D construction simulation. The result obtained from the testing process suggests that the mathematical method is capable of predicting and reduce site space conflict. However, it has been recommended to extend the code verification and validation process through implementing the proposed method in various case of study.
