Utilizing BIM 4D in Improving Project Execution Scheduling A Realistic Project for the Mosul Municipality as a Case Study

Abstract

The architectural projects in Iraq, designed according to the traditional method, face problems of the delay in the completion of work and the increase in the cost. The paper adopts the implementation of BIM system in the field of architectural design as one of the leading digital systems for estimating project scheduling accurately. The research problem was to identify the requirements for applying BIM 4D (one of the BIM tasks) in architectural projects in Iraq. The research goal was to determine the requirements of applying BIM 4D in public sector projects in Iraq. The research identifiedthe most important prerequisites, for examples: the adoption of Iraqi codes in defining the libraries of components involved in the design, the definition of the detailed components of building to take into account the local market such as manufacturers, setting determinants that require cooperation and communication between the relevant government agencies and the diverse design teams during the design phase to avoid future conflicts, and ensuring early participation of the contractor in the design stages.
