Site Planning, Structural Inspection, and As-Built Verification for Industrial & EPC

Industrial and EPC projects demand precision at every phase - from site selection through commissioning. Aeroyantra delivers survey-grade drone mapping and LiDAR for industrial facilities, power plants, refineries, and EPC projects - giving project teams the spatial data they need for site planning, structural inspection, and as-built verification.

Industrial Projects Fail Their Design Intent When the Spatial Data Underpinning Them Is Inaccurate

Industrial and EPC projects are built to tight tolerances. Equipment foundations that are 50 mm off design create alignment problems that compound through the entire facility. Pipe racks that deviate from design create interference issues discovered during commissioning. As-built documentation assembled from incomplete field records does not support operations and maintenance.

The pattern repeats across industrial projects:

• Site selection decisions made on outdated topographic data - Drainage, access, and foundation design based on data that does not reflect current site conditions

• Foundation deviations discovered after equipment installation - Equipment foundations that are off-level or misaligned create problems during commissioning

• Structural geometry deviations go undetected - Columns, beams, and pipe racks that deviate from design create interference and alignment issues

• As-built documentation assembled reactively - Facility as-built records built from incomplete field measurements that do not support operations planning

• Progress reporting is subjective - Site visits cover a fraction of a large industrial facility and ground-level visibility is limited

Survey-Grade Spatial Data for Industrial Facilities

Aeroyantra delivers drone mapping and LiDAR workflows purpose-built for industrial and EPC projects - where tight tolerances, complex geometry, and as-built documentation requirements demand accuracy and traceability.

With RTK, PPK, and GCP-supported workflows, Aeroyantra achieves 2-3 cm horizontal accuracy and vertical precision suitable for site planning, foundation verification, structural inspection, and as-built documentation.

What that means for industrial projects:

• Accurate site baseline - Survey-grade topographic data for site selection, drainage design, and foundation planning

• Foundation verification - Confirmed foundation levels and positions before equipment installation

• Structural geometry verification - 3D comparison of structural elements against design for quality control

• As-built facility documentation - Complete aerial record of the finished facility for operations and maintenance planning

• Progress tracking - Weekly or monthly aerial records for client reporting and schedule management

• BIM and CAD compatibility - All deliverables compatible with Autodesk Revit, Navisworks, AutoCAD Plant 3D, and standard GIS platforms

Site Planning and Pre-Construction Survey

Accurate Site Data Before Design Decisions Are Made

Industrial site selection and planning decisions made on inaccurate topographic data produce drainage problems, access issues, and foundation design errors that compound through the project lifecycle.

What Aeroyantra delivers for site planning:

• High-resolution site orthomosaic - True-color aerial imagery at 1-3 cm/pixel for site layout planning and stakeholder presentations

• Digital Terrain Model (DTM) - Bare-earth surface model for drainage design, cut/fill analysis, and foundation planning

• Contour mapping - Engineering-grade contour data for site grading and drainage design

• Site access and logistics planning - Aerial data for haul road planning, laydown area identification, and construction logistics

• Utility and infrastructure mapping - Identification of existing utilities, structures, and site features for demolition and clearance planning

• Environmental baseline documentation - Pre-construction site condition record for environmental compliance and regulatory submissions

Foundation and Structural Verification

Catch Deviations Before Equipment Installation

Equipment foundations that are off-level or misaligned create problems during commissioning. Aeroyantra verifies foundation levels and structural geometry against design before equipment installation proceeds.

What Aeroyantra delivers for structural verification:

• Foundation level verification - Confirmed elevation data for equipment foundations before installation

• Structural geometry verification - 3D comparison of columns, beams, and structural elements against design

• Pipe rack alignment verification - Alignment and level verification of pipe racks and cable trays before piping installation

• Equipment pad verification - Level and position verification of equipment pads and mounting surfaces

• BIM overlay comparison - Current facility condition compared against BIM model to identify deviations

• Deviation heatmap - Color-coded visualization showing where construction matches design and where it deviates

As-Built Documentation and Facility Handover

Complete Aerial Record of the Finished Facility

As-built documentation assembled from incomplete field records does not support operations and maintenance planning. Aeroyantra produces a complete aerial record of the finished facility at survey-grade accuracy.

What Aeroyantra delivers for as-built documentation:

• Final facility orthomosaic - High-resolution aerial imagery of the completed facility for operations planning

• 3D facility model - Photogrammetric or LiDAR-derived 3D model of the facility for maintenance planning and future expansion design

• Equipment and structure inventory - Georeferenced inventory of major equipment, structures, and facility features

• Pipe rack and utility mapping - Aerial mapping of above-ground piping, cable trays, and utility infrastructure

• Access and safety planning data - Aerial data for emergency response planning, safety training, and access route identification

• BIM-compatible as-built model - As-built 3D model in IFC or RVT format for integration with facility BIM

Frequently Asked Questions

Q1: Can Aeroyantra verify equipment foundation levels before installation?

Yes. With RTK or PPK georeferencing, Aeroyantra achieves vertical precision suitable for foundation level verification. Foundation elevation data is extracted from the survey surface model and compared against design levels, with deviation reports generated for quality control before equipment installation proceeds.

Q2: Can Aeroyantra data be integrated with facility BIM models?

Yes. Aeroyantra exports IFC, RVT, DXF, and LAS/LAZ formats that integrate directly with Autodesk Revit, Navisworks, AutoCAD Plant 3D, and standard BIM platforms. 3D models and point clouds can be used for BIM overlay comparison, clash detection, and as-built model development.

Q3: At what project phases should industrial facility surveys be conducted?

Aeroyantra recommends surveys at four key phases: pre-construction site baseline, post-foundation before equipment installation, mid-construction for progress tracking and BIM comparison, and final as-built at practical completion. The pre-construction and post-foundation surveys deliver the highest return on investment.

Q4: Can Aeroyantra survey active industrial facilities with ongoing operations?

Yes, with appropriate safety planning and coordination with facility management. Surveys are conducted during scheduled shutdown windows or from safe standoff distances that do not interfere with operations. All operations comply with facility safety protocols and DGCA regulations.

Q5: How quickly are deliverables available after survey?

Standard deliverables - orthomosaics, DSM, DTM, and 3D models - are available within 24-48 hours of flight completion. BIM overlay comparison and deviation analysis reports are typically available within 48-72 hours depending on model complexity.
