Optimizing Earthworks & Cost Estimation in Construction: The Impact of LiDAR Technology & Drones

When it comes to construction projects, accuracy and cost savings are key. Leonard S. Fiore Inc. (LSF) was able to achieve both of these by using LiDAR technology and drones to accurately measure and survey land before starting a project. This helped them save a significant amount of money, over $300,000 to be exact, in materials and labor costs.

One specific project that LSF worked on was the remodel of a high school sports field complex. By using LiDAR technology and drones, they were able to create a detailed and accurate 3D model of the land which allowed them to plan better, use less resources, and work more efficiently.

An example of how this technology helped was in the construction of the bleachers. The project required the footers to be set three feet below the existing grade. However, during excavation, LSF discovered discrepancies in the elevations shown on the plans.

If they had followed the plans, nearly half of the footers would have been sitting on grade rather than three feet below. By using LiDAR data, LSF was able to re-establish the proper top-of-footer elevations based on the true contours of the slope, which resulted in a net zero cut fill and no extra dirt needed to be removed from the site, ultimately saving on resources.

In conclusion, LiDAR technology and drones have become a powerful tool in the construction industry, not just for cost savings but also for achieving greater accuracy and efficiency in construction projects.
