NG Net PLLC

Measure Progress. Monitor Earthwork. Document Construction.

NG Net PLLC provides professional UAS mapping, construction progress documentation, earthwork analysis, and geospatial data processing for contractors, engineers, developers, and infrastructure owners.

Drone-based photogrammetry and LiDAR can provide detailed three-dimensional information about construction sites, stockpiles, excavations, and changing ground conditions.

By integrating aerial data with survey control, surface modeling, and geospatial analysis, we help clients maintain measurable records of construction progress and support project planning, quantity review, and documentation.

Our services are available for complete UAS mapping projects or processing and analysis of suitable client-provided drone data.

Our Construction Drone Services

• Construction Progress Mapping: Periodic aerial mapping to document site conditions and track project development.
• Stockpile Volume Calculations: Three-dimensional surface analysis for aggregate, soil, excavation materials, and other stockpiles.
• Cut-and-Fill Analysis: Volume calculations using existing, proposed, and previously collected surface data.
• Excavation Monitoring: Mapping and measurement of excavation areas, material removal, and changing site conditions.
• Site Grading Documentation: Surface generation, elevation analysis, and comparison with design grading information.
• Construction Site Mapping: High-resolution orthomosaics, point clouds, contours, and existing-condition documentation.
• As-Built Mapping Support: Geospatial documentation of completed work and constructed site features.
• Infrastructure Construction Documentation: Aerial mapping of roads, bridges, utilities, and other construction projects.
• Construction Change Analysis: Comparison of datasets collected at different stages of a project.

Stockpile & Earthwork Volume Analysis

NG Net PLLC provides volume calculations using photogrammetric point clouds, LiDAR datasets, digital surfaces, and available survey information.

Services may include:

• Stockpile volume calculations
• Surface-to-surface volume comparisons
• Existing-versus-design surface analysis
• Cut-and-fill calculations
• Excavation quantity analysis
• Terrain and grading comparisons
• Quantity exhibits and reports
• Review of surface boundaries and reference elevations

Calculation assumptions, surface boundaries, base surfaces, and relevant control information can be documented as part of the project deliverables.

Construction Progress & Repeat Mapping

Repeat aerial mapping provides a consistent record of site development over time.

Depending on project requirements, collected data can be used to document:

• Site preparation
• Excavation and earthwork
• Grading progress
• Material stockpiles
• Infrastructure construction
• Completed site improvements
• Changes between project milestones

Comparison of georeferenced imagery, point clouds, and surfaces can help clients evaluate site changes and maintain organized construction records.
