Question 1

What types of industrial facilities can you survey?

Accepted Answer

We survey manufacturing plants, solar farms, power plants, refineries, warehouses, and industrial parks. Services include pre-construction terrain mapping, as-built documentation, facility inspection, and expansion planning support.

Question 2

How do solar site surveys help with panel layout planning?

Accepted Answer

Our surveys provide slope analysis, aspect mapping, shading study support, and 3D terrain models. This data helps optimize panel placement, calculate mounting requirements, and identify areas unsuitable for installation.

Question 3

Can you survey operational industrial plants?

Accepted Answer

Yes, we coordinate with facility teams to survey during operational hours following safety protocols. Our drones can capture overhead imagery without disrupting production or requiring equipment shutdown.

Question 4

What deliverables are useful for plant expansion projects?

Accepted Answer

We provide as-built orthomosaics showing current layout, 3D models for visualization, terrain data for foundation design, and CAD-compatible files for integration with expansion plans.

Question 5

How accurate are surveys for solar plant design?

Accepted Answer

We achieve 5-10cm accuracy suitable for panel layout planning and civil design. Terrain models include slope analysis and elevation data needed for mounting structure design and drainage planning.

Question 6

At what project phases should we fly drone surveys for EPC projects?

Accepted Answer

For maximum value, we recommend surveys at five key phases: pre-construction baseline, earthworks validation (tied to billing cycles), structural milestones before critical work proceeds, mechanical and installation completion, and final as-built closeout. The pre-construction baseline and as-built closeout surveys are the minimum viable set for any EPC project.

Question 7

How accurate is drone-based volume measurement for earthworks and stockpiles?

Accepted Answer

With RTK or PPK georeferencing, we achieve earthwork volume accuracy within 1% for well-defined cut-and-fill areas and stockpile volumes. This compares to typical variance of 5-15% from manual estimation methods. Accuracy depends on flight parameters, GSD, and site-specific conditions.

Question 8

Can you compare drone survey data against our design BIM or CAD model?

Accepted Answer

Yes. We support design-to-as-built comparison workflows where the processed orthomosaic, DSM, or LiDAR point cloud is aligned against your design model. The output is a deviation heatmap and quantified report showing where construction deviates from design intent, at user-defined tolerance thresholds. Supported formats include DXF, DWG, IFC, and major BIM platform exports.

Question 9

Can drones inspect confined spaces and hazardous areas on industrial sites?

Accepted Answer

Yes. LiDAR-equipped drones can inspect the interior of tanks, silos, vessels, and other confined spaces without personnel entry - eliminating the need for confined space entry permits, standby crews, and associated safety risks. Internal LiDAR scans produce a complete 3D model of the interior geometry for structural assessment and maintenance planning.

Question 10

Is thermal inspection available alongside standard photogrammetry and LiDAR surveys?

Accepted Answer

Yes. Thermal payload integration is available for industrial inspection workflows. A single mission can collect RGB, LiDAR, and thermal data simultaneously, producing a fused dataset where thermal anomalies are georeferenced against the 3D site model for precise location and context.

Question 11

Can drone inspections replace rope access and scaffold inspections on oil and gas assets?

Accepted Answer

For external condition assessment, drone inspections replace the majority of rope access and scaffold inspection work on oil and gas assets. High-resolution close-range drone imagery captures surface condition, corrosion, coating failure, and mechanical damage at a level of detail comparable to manual visual inspection - without personnel access to the asset. LiDAR surveys add quantified geometric data that manual inspection cannot produce.

Question 12

How does Aeroyantra support OISD compliance documentation requirements?

Accepted Answer

Aeroyantra produces georeferenced, time-stamped inspection records for each survey cycle, with photographic evidence, LiDAR geometry data, and thermal anomaly reports traceable to the specific inspection date and asset. This documentation format supports OISD periodic inspection requirements and provides the audit trail required for regulatory compliance. Report formatting can be configured to align with specific OISD standard requirements.

Question 13

Can Aeroyantra survey long pipeline corridors efficiently?

Accepted Answer

Yes. For photogrammetry and right-of-way monitoring, a single drone covers 50-100 km of pipeline corridor per day depending on flight altitude and corridor width. For LiDAR surveys, coverage of 50+ km per day is achievable on open terrain. Multi-drone deployments are available for projects requiring faster acquisition across very long pipeline networks.

Question 14

How does thermal drone inspection detect pipeline leaks?

Accepted Answer

Hydrocarbon product leakage from buried or above-ground pipelines creates thermal anomalies at the surface - either from the temperature difference between the product and the surrounding soil, or from evaporative cooling effects at the leak point. Thermal drone surveys detect these anomalies as temperature contrast patterns on the pipeline route surface. Thermal inspection complements but does not replace subsurface leak detection methods for buried pipelines.

Question 15

How does drone-based pile alignment verification work for solar projects?

Accepted Answer

After piling is completed, a drone survey captures high-resolution imagery and a 3D model of pile cap positions. Pile cap centroids are extracted and compared against the design layout. Position deviations are calculated for each pile and displayed as a color-coded deviation map. With RTK or PPK georeferencing, pile position accuracy of 2-3 cm is achievable - sufficient to identify piles outside mounting structure tolerance before structures are erected.

Question 16

When should thermal inspection be conducted on a solar project?

Accepted Answer

Thermal inspection should be conducted at three key points: at commissioning before handover, at the end of the first operational year to identify early-onset defects while warranty coverage is active, and annually or bi-annually through the operational lifecycle. Commissioning thermal inspection is the highest-value event - defects identified at this stage can be remediated under EPC warranty.

Question 17

Can drone surveys support SECI and state discom project documentation requirements?

Accepted Answer

Yes. We produce georeferenced, time-stamped aerial records and progress reports suitable for SECI project monitoring, state discom construction verification, and lender independent engineer reporting. Progress documentation can be formatted to match specific project monitoring requirements. We recommend confirming format requirements with your project's independent engineer before the first survey cycle.

Question 18

Can Aeroyantra support PM-KUSUM and PM Surya Ghar project documentation?

Accepted Answer

Yes. We support pre-construction site surveys, installation progress documentation, and commissioning inspection for PM-KUSUM agricultural solar and PM Surya Ghar rooftop solar projects. For PM-KUSUM feeder separation and pump electrification projects, drone surveys provide the terrain and infrastructure mapping data required for project design and implementation documentation.
