Can you describe any instances where you had to make design changes during a project? How did you handle it?

Sample interview questions: Can you describe any instances where you had to make design changes during a project? How did you handle it?

Sample answer:

  1. Underground Utility Conflicts:

During the construction of a new residential development, we encountered unexpected underground utility conflicts. The original design called for a sewer line to be installed in a specific location, but upon excavation, we discovered an existing gas line directly in the path of the proposed sewer line.

Solution:

We immediately convened a meeting with representatives from the local utility companies, the contractor, and the project owner to discuss the situation. After careful consideration of the available options, we decided to reroute the sewer line to avoid the gas line. This involved redesigning the drainage system for the entire development, which required close coordination with the design team and the contractor.

  1. Geotechnical Issues:

While working on a road expansion project, we encountered unforeseen geotechnical issues during the excavation process. The soil conditions were not as stable as anticipated, leading to concerns about the stability of the road embankment.

Solution:

We promptly brought in a geotechnical engineer to assess the situation and provide recommendations. Based on the engineer’s findings, we modified the design to include additional geotechnical measures, such as soil stabilization and the installation of retaining walls. This required close collaboration with the contractor to ensure the proper implementation of the revised design.
