Landing a job as a BIM designer requires not only technical expertise but also the ability to communicate your skills effectively in an interview. With the rising demand for BIM in the architecture engineering and construction industries, companies are eager to hire designers who can create detailed 3D models and manage information-rich BIM processes.
This article provides a comprehensive overview of common BIM designer interview questions, sample answers, and tips to help you make a winning impression.
Overview of the BIM Designer Role
First, let’s look at what good BIM designers have that employers want to see:
- In-depth knowledge of BIM software like Revit, Navisworks, BIM 360 etc.
- Understanding of architecture and building systems
- Strong visualization and problem-solving skills
- Ability to collaborate with cross-disciplinary teams
- Excellent communication skills
- Attention to detail and organizational skills
In your interview answers focus on demonstrating these capabilities beyond just your technical proficiency. Elaborate on how you deliver value and impact project outcomes positively.
Now let’s look at some of the most frequently asked BIM designer interview questions and how to craft impressive responses.
Technical Questions
As for the different LOD (Level of Detail) levels in BIM, could you explain what they’re used for?
A: The main LOD levels are LOD 100, 200, 300, 350 and 500. LOD 100 requires overall building massing, LOD 200 has generalized systems, LOD 300 includes more precisely modeled elements, LOD 350 is fabrication-level modeling, and LOD 500 represents an as-built BIM model. Specifying LODs ensures efficient use of effort and prevents creating details too early. I apply my knowledge of LODs to determine the right level of information needed for each stage of a project.
What is an Autodesk Revit workset, and how do you use one in your work?
A: A workset allows grouping elements in a Revit model and controlling visibility and edit permissions. For example, I create separate worksets for architecture, structure and MEP for better coordination. Worksets improve performance when working with large files. I also assign worksets to different team members to avoid clashes and streamline workflows.
Q: Could you explain the difference between type and instance parameters in Revit?
A: Type parameters control properties for a category of elements like walls, floors etc. Changing the type parameter updates all instances of that element. Instance parameters modify properties of a particular instance without affecting the rest. When detailing, I use a combination of type and instance parameters to find the right balance between efficiency and control.
Q: What is the purpose of Autodesk BIM 360 and how have you used it on past projects?
A: BIM 360 is a cloud-based platform that centralizes information management across project teams. It facilitates model coordination, issue tracking, scheduling, and more. I have used BIM 360 for clash detection by merging models from various disciplines. It improved transparency and helped resolve clashes before construction. I have also utilized it for submitting RFIs, tracking responses and communicating with teams.
Q: How can you use an IFC file exported from architectural modeling software like Revit in your BIM workflow?
A: IFC or Industry Foundation Class format facilitates interoperability between BIM platforms. To incorporate an architectural IFC model, I link it into my native Revit model for coordination while retaining the ability to modify my model separately. I can also import it into Navisworks for clash detection with MEP models. Using IFC improves collaboration and avoids data loss from software-specific formats.
Q: In your experience, which architectural element is the most challenging to model and detail precisely in Revit?
A: From my experience, curved walls and surfaces can be particularly challenging. Accurately representing the curvature while accounting for material properties requires a nuanced approach. I overcome this by using reference lines to define the curve geometry before modeling walls. I also simplify complex forms by approximating curves as arcs and lines. Finally, I leverage Revit’s curtain wall system which provides more flexibility.
Behavioral Questions
Q: Tell me about a time you had to collaborate with other stakeholders to solve a problem using BIM.
A: In one project while linking the architectural and MEP models, we found MEP ductwork clashed with structural beams. I coordinated with the architects and MEP engineers to analyze the clash in Navisworks. We decided to move the beams slightly to resolve it. This quick solve prevented major rework later. The experience demonstrated the value of early BIM coordination to me.
Q: Describe a situation where you had to manage a complex BIM project. How did you ensure efficiency?
A: In a hospital project I modeled, the BIM model grew very large with the architectural, MEP and structural data. To improve performance, I divided it into smaller manageable files. I also created local files with links to the main model, allowing teams to work in parallel. Applying strategies like simplifying details, using optimal view settings, and setting up server accelerators enabled efficient coordination despite the complexity.
Q: How do you prioritize when managing multiple BIM projects with conflicting deadlines?
A: When handling competing priorities, I first assess urgency and potential impact of delays. I touch base with relevant stakeholders to align on timelines and delays, if any. I create a detailed schedule mapping milestones and upcoming handovers. Tracking it regularly helps me re-prioritize whenever needed while maintaining transparency. Open communication with teams also allows better planning and collaboration when priorities shift.
Q: Have you mentored or trained anyone in BIM workflows? What approaches did you find effective?
A: Yes, I have trained interns and new hires in using Revit, Navisworks and BIM 360. I found stepping through model creation workflows in Revit using examples to be very effective. I encourage self-exploration in the software while providing guidance. To explain theory like LODs, I use real project examples for better context. I believe mentoring helps me improve my own skills while advancing collective team knowledge.
Technical Questions
Q: What experience do you have with eco-building analysis tools such as Sefaira Architecture or Integrated Environmental Solutions Virtual Environment?
A: Though I don’t have direct experience with those specific tools, I have used Autodesk Revit’s Solar Analysis functionality for a daylighting study. I also have basic experience with EnergyPlus energy modeling integrated with Revit. I am eager to expand my skills in building performance analysis using solutions like Sefaira and IES-VE. I consider it an invaluable capability for sustainable building design, which is a priority for me.
Q: How familiar are you with BIM standards like PAS 1192 and ISO 19650? How do you ensure compliance on projects?
A: I am well-versed in the core principles outlined in PAS 1192 and ISO 19650 – from collaborative working to structured information management. On all projects, I advocate for clearly defining the BIM Execution Plan right at the start, including the information delivery milestones. Maintaining a Common Data Environment and using COBie data schemas also ensure compliance. Adhering to these standards is key for successful BIM adoption, which I communicate clearly to my team.
Q: What is your experience with integrating BIM workflows with VR technology? How does this add value?
A: I have used VR technology in combination with Navisworks BIM models for design reviews and coordination meetings. Using interactive 3D walkthroughs helped the client and contractors visualize designs and propose modifications early on. This increased engagement and accelerated approvals. There is tremendous value in augmenting BIM with advanced visualization technology, especially for stakeholders less familiar with model navigation.
