Describe a time when you had to adapt your surveying techniques to accommodate unique site conditions.
Geodetic Surveyor Interview Questions
Sample answer to the question
During a surveying project for a new construction site, we encountered unique site conditions that required us to adapt our techniques. The site was located on a steep hillside with dense vegetation, making it difficult to access and survey the area. To accommodate these conditions, we used a combination of traditional surveying equipment and GPS systems. We also had to modify our surveying approach by establishing additional benchmarks and reference points at different elevations to accurately capture the contours of the site. This allowed us to gather precise data and create accurate maps for the construction team.
A more solid answer
During a surveying project for a new construction site, we encountered unique site conditions that required us to adapt our techniques. The site was located on a steep hillside with dense vegetation, making it challenging to access certain areas for surveying. To overcome this, we utilized advanced surveying equipment, including GPS systems and laser scanners, to gather accurate data without the need for physically traversing difficult terrain. We also employed a combination of traditional surveying methods and remote sensing techniques to capture the topographic features of the site. This involved using a drone to collect aerial imagery and LiDAR data, which was then processed to create a detailed digital terrain model. By incorporating these innovative approaches, we were able to effectively adapt our surveying techniques to accommodate the unique site conditions and provide precise information for the construction team.
Why this is a more solid answer:
The solid answer provides more specific details about the surveying techniques used such as GPS systems, laser scanners, remote sensing techniques, and the incorporation of drone imagery and LiDAR data. It demonstrates a deeper understanding of geodetic and topographic surveying practices by mentioning the use of digital terrain model and the ability to gather accurate data without physically traversing difficult terrain. However, it still lacks mention of the ability to manage and prioritize multiple tasks.
An exceptional answer
During a surveying project for a new construction site, we encountered unique site conditions that required us to adapt our techniques. The site was located in a coastal area prone to tidal fluctuations, which presented challenges in obtaining accurate elevation data. To address this, we utilized real-time kinematic GPS (RTK-GPS) technology combined with total stations to minimize the impact of tidal changes on the survey measurements. Additionally, we implemented a rigorous quality control process to ensure the accuracy and reliability of the data collected. This involved conducting redundant measurements and cross-referencing the results to identify and eliminate any outliers. To further accommodate the unique site conditions, we deployed specialized equipment designed for hydrographic surveying to accurately capture the depths and contours of submerged areas. These adaptations allowed us to overcome the challenges posed by the tidal fluctuations and provide the construction team with precise data for their planning and design purposes.
Why this is an exceptional answer:
The exceptional answer goes beyond the solid answer by addressing a specific and complex challenge related to tidal fluctuations in a coastal area. It introduces the use of real-time kinematic GPS technology combined with total stations to minimize the impact of tidal changes. It also highlights the implementation of a rigorous quality control process and specialized equipment for hydrographic surveying. This answer demonstrates a high level of expertise in adapting surveying techniques to accommodate unique site conditions.
