Can you provide examples of how you handle any discrepancies or inconsistencies found in survey data?

Construction Surveyor Interview Questions

Sample answer to the question

In my previous job, I often encountered discrepancies in survey data. When I found inconsistencies, what I would do was first recheck the raw data myself. If I was the one who made the measurements, I would go back to the spot and measure again. If the same inconsistency kept appearing, I would speak to my supervisor and my team, asking for their opinions and advice. If necessary, we could hire a third-party surveyor for re-surveying or further advice. It was all about making sure to get to the truth of the measurements and making sure that they were accurate.

A more solid answer

Throughout my career, dealing with discrepancies or inconsistencies in survey data has been a constant. Here’s an example: While working on a residential development project, I found an anomaly in the field compared to the already established survey data. I immediately rechecked my measurements using different equipment, including a GPS and a total station. I recalculated the data, applying my mathematical skills in geometry and trigonometry. When the discrepancy persisted, instead of neglecting it, I communicated this issue to the project manager and the lead engineer. We decided to consult geomatics experts and rerun the entire field data collection. By doing so, we discovered a slight deviation in the original data due to landscape changes over time. Correcting the data timely prevented any potential construction issues and saved the company from future legal issues.

Why this is a more solid answer:

This solid answer provides a concrete example of using professional skills and tools to address a discrepancy. In addition to demonstrating their analytical and problem-solving skills, the candidate shows how they apply their mathematical and technical proficiency. They also indicate their communication skills and ability to collaborate as a team to resolve the issue. However, they could further enhance the answer by sharing how their effort led to tangible positive impacts on the project or organization.

An exceptional answer

Dealing with discrepancies in survey data is an aspect I take seriously due to the implications it could have on the integrity of a project. For example, while working on a major mixed-use development project, I noticed an inconsistency between the recorded land elevation and my readings during the data processing stage. Instead of disregarding it, I revisited the survey site and performed the survey again under different weather conditions to ensure utmost accuracy. I used a blend of GPS and EDM technology to validate my findings. Applying my knowledge in algebra, geometry, and trigonometry, I reprocessed the data on a CAD software platform. Persisting discrepancy signaled me that there was a potential issue. I utilized my strong communication skills to report this matter to the site engineer and the project manager. Together with the design team, we arranged for a third-party surveyor. The further investigation revealed errors not in my survey but in the initial topographic survey done prior to my engagement. Resolving this allowed us to adjust the construction plan and avert potential zoning law violations. It ultimately saved the project significant time, resources, and potential legal complexities.

Why this is an exceptional answer:

This response goes above and beyond in detailing how the candidate identifies, investigates, and resolves discrepancies in survey data, applying a wide range of professional skills. Along with showing their technical and mathematical competence, the candidate also shows their commitment to detail, problem-solving ability, and team collaboration skills. The mention of their proactive communication and how their work resulted in significant project savings and compliance with legal requirements makes this an exceptional answer.
