Benefits of Using BIM Tools to Resolve Clashes in Iraqi Construction Projects: A Case Study

Abstract

When the components that make up a built asset are not spatially coordinated and clashed, this is referred to as a clash in design language. These incompatibilities can be identified more quickly in a BIM process during the design phase of a project, before construction begins on site. Most construction projects in Iraqi ministries suffer from a lack of coordination between project parties, which leads to problems in later project stages, particularly during the building stage, when one of the primary issues is a confrontation between civil, architectural, and other parties. This study aims to shed light on architectural element clashes and detect them early in the design process, resulting in fewer errors during the implementation phase. The study conducted a quantitative technique that included creating a questionnaire divided into three sections and focused on time and expense overruns. The result showed that, (The financial deficit of the contractor) is the most critical factor; (the contractor’s non-compliance with the technical specifications) was the second rank. The second part (Using Building Information Modeling technology that reduces and resolving clashes between project elements during the design phase) was the most critical factor. Moreover, the second factor is (BIM technology increases communication between the project team) is the second rank.
