Civil works often constitute a major risk variable and cost center in EPC projects. This briefing shows how Ultrathon Electric utilizes advanced surveying and simulation to optimize layouts and drastically reduce the Bill of Quantities (BOQ) for civil structures.
RTK-Enabled Drone Topography
Traditional surveying methods are slow and often lack the necessary resolution. We employ Real-Time Kinematic (RTK) drones to generate highly accurate 3D digital elevation models (DEMs). This high-fidelity data allows our engineering team to map the terrain with centimeter-level precision, identifying potential drainage issues and avoiding costly earthworks.
Geotechnical Analysis and Pile Design
Understanding the soil profile is critical. We combine the drone data with comprehensive geotechnical soil testing to determine the optimal pile driving depth and profile for the Module Mounting Structures (MMS). By tailoring the pile design to specific soil zones across a massive site, we minimize steel tonnage and ensure structural integrity against high wind loads.
3D Simulation and Cut-and-Fill Reduction
Using specialized software (like PVcase), we simulate the MMS placement directly on the 3D terrain model. This allows us to optimize the row spacing and tilt angles to match the natural undulations of the land, significantly reducing the need for extensive cut-and-fill grading operations, thereby accelerating the construction schedule and minimizing environmental impact.
