Tell me about a time when you identified clashes and conflicts in BIM models. How did you resolve them and what was the impact on the project?

Building Information Modeling (BIM) Specialist Interview Questions

Sample answer to the question

In my previous role as a BIM Specialist, I encountered clashes and conflicts in BIM models on a regular basis. One specific instance that comes to mind is during a large-scale commercial project. I discovered clashes between the HVAC ductwork and the structural elements of the building. To resolve this issue, I organized a meeting with the HVAC and structural teams to discuss the conflicts and brainstorm potential solutions. We identified a suitable alternative routing for the ductwork that eliminated the clashes without compromising the overall design. The impact of resolving these clashes was significant as it prevented potential delays and rework during construction, saving both time and money for the project.

A more solid answer

During a commercial project, I encountered clashes in the BIM models between the HVAC ductwork and the structural elements. To resolve this, I utilized advanced knowledge of BIM software, specifically Navisworks, to perform clash detection and analysis. I created clash reports and presented them during project meetings to raise awareness of the conflicts. I collaborated with the HVAC and structural teams to find suitable solutions, considering factors such as space constraints and design requirements. By identifying alternative routing for the ductwork, we were able to eliminate the clashes and ensure a smooth construction process. This resolution had a significant impact on the project, as it prevented costly rework and potential delays, contributing to the overall success of the project.

Why this is a more solid answer:

The solid answer expands on the basic answer by providing more details about the candidate's BIM software knowledge and their analytical and problem-solving skills. The candidate specifically mentions the use of Navisworks for clash detection and analysis, demonstrating their proficiency in BIM software. The answer also describes the candidate's collaboration with the HVAC and structural teams, highlighting their excellent communication and teamwork abilities. Additionally, the impact on the project is highlighted by emphasizing the prevention of rework and delays, and the contribution to the overall success of the project. Despite the improvements, the answer could benefit from giving more information about the specific clash detection process and providing an example of how the candidate trained and supported team members in BIM processes.

An exceptional answer

In a large-scale commercial project, I encountered clashes in the BIM models between the HVAC ductwork and the structural elements. To address this, I followed a comprehensive process that showcased my expertise in BIM software, analytical skills, and ability to train and support team members. Firstly, I used Navisworks for clash detection, creating clash reports that identified the conflicts between the ductwork and structural elements. I conducted thorough analysis, considering factors like space constraints and design requirements. To resolve the clashes, I facilitated meetings with the HVAC and structural teams, where I presented the clash reports and encouraged open communication and collaboration. We collectively brainstormed possible solutions and evaluated their feasibility. By utilizing my advanced proficiency in BIM software, I created 3D visualization models showcasing the proposed alternative routing for the ductwork. These visualizations allowed stakeholders to assess the impact and make informed decisions. Additionally, I provided training and support to team members on utilizing BIM software effectively, empowering them to identify clashes independently and propose viable solutions. The impact on the project was substantial. By proactively resolving clashes, we prevented costly rework and eliminated potential delays. This not only saved time and resources but also fostered smooth collaboration among different disciplines. Ultimately, the successful resolution of clashes positively influenced the project's progress and quality.
