The goal of this FAQ is to provide clear answers to common questions about AeroTek Engineering Solutions Ltd’s surveying and geospatial services. It is structured to assist law firms, developers, government agencies, utility companies, and residential property owners in understanding our services within the context of Guernsey’s regulations and industry requirements.

General Questions

What services does AeroTek offer?

We provide the following services:

• Surveying and Mapping – Using GNSS-based land surveys, aerial mapping, and terrestrial LiDAR to capture boundary lines, topographic data, and detailed site documentation.

• Data Processing and GIS-CAD-BIM Integration – Converting raw aerial and terrestrial scans into orthomosaics, classified point clouds, and GIS outputs for seamless CAD/BIM integration.

• 3D Models and Asset Inspection – Creating digital twins of the built environment using LiDAR and photogrammetry techniques for remote asset inspection and maintenance planning.

• Deformation Studies– Monitoring structural movement over time to assess the stability of buildings, bridges, and industrial infrastructure.

• Infrastructure and Industrial Asset Inspections – Using sUAS (small Uncrewed Aerial Systems) to inspect industrial sites, power stations, telecom towers, and transport infrastructure.

How do I determine which type of survey I need?

The best survey for you depends on your project. If you are unsure, our team can advise on the most suitable service.

Are AeroTek’s surveys legally recognised in Guernsey?

Yes. Our surveys comply with the Land Planning and Development (Guernsey) Law, 2005, ensuring they meet local regulatory standards. The documentation provided can be used for planning applications, land transactions, and legal proceedings.

Boundary & Property Surveys

What is a boundary survey, and why is it important?

A boundary survey determines the exact legal limits of a property. It is essential for:

• Property transactions – Ensuring accurate property descriptions.

• Development projects – Preventing encroachments and legal disputes.

• Homeowners – Clarifying property limits before installing fences or making extensions.

Can a boundary survey assist in legal disputes?

Yes. A boundary survey provides definitive evidence of property limits, which can be used in legal cases to settle disputes. It is often commissioned by solicitors and property owners in Guernsey.

Is a boundary survey necessary before selling a property?

A boundary survey is not legally required in Guernsey, but it is highly advisable for:

• Confirming property dimensions before sale.

• Identifying potential encroachments that could affect transactions.

• Providing buyers with assurance regarding land ownership.

Construction & Development Surveys

Why are surveys essential before construction?

Surveys ensure:

• Accurate site measurements for design and development.

• Regulatory compliance with Guernsey’s building control requirements.

• Identification of potential issues such as terrain challenges and drainage concerns.

A pre-construction survey helps prevent costly mistakes and ensures efficient project execution.

What is a topographic survey?

A topographic survey provides detailed information about land elevations, features, and existing structures. It is required for:

• Planning new buildings and infrastructure.

• Assessing drainage and water flow.

• Integrating natural features into landscape design.

Topographic surveys form the foundation for most development projects.

Do you provide as-built surveys?

Yes. As-built surveys document the final construction to ensure it aligns with the approved plans. These are used for:

• Regulatory compliance – Demonstrating that a project meets planning requirements.

• Future modifications – Providing a baseline for renovations.

• Property records – Maintaining accurate documentation.

Infrastructure & New

Utility Installations

Do you provide underground utility mapping?

We do not map existing underground utilities. However, we provide surveying and geospatial mapping for new utility installations, ensuring that pipelines, cables, and infrastructure are accurately placed and recorded.

How do AeroTek’s surveying services benefit utility companies and infrastructure projects?

Our surveying services support the installation of new infrastructure by providing:

• Precision layout and alignment surveys – Ensuring new pipes, cables, and utility assets are installed according to design specifications.

• Geospatial documentation – Creating accurate records for newly installed infrastructure.

• Regulatory compliance mapping – Providing verified positional data for planning authorities.

Our work ensures that new utility installations are properly positioned and documented from the outset.

Deformation Monitoring

& Asset Inspection

What is a deformation survey?

A deformation survey monitors the movement of a structure over time, detecting shifts, subsidence, or gradual settling. It is crucial for:

• Industrial and commercial structures – Assessing long-term stability.

• Bridges and transport infrastructure – Identifying movement or stress over time.

• Tunnels and underground assets – Detecting structural shifts.

What types of infrastructure and industrial assets do you inspect using sUAS?

We conduct UAV-based remote inspections for:

• Telecom towers and masts – Assessing structural integrity and performing line-of-sight analysis.

• Bridges and road networks – Monitoring corrosion, deformation, and structural movement.

• Industrial sites and structures– Inspecting roofs, external façades, and hard-to-reach structures.

sUAS-based inspections enhance safety, reduce operational downtime, and provide high-resolution imagery for informed decision-making.

Costs, Timing & Project Logistics

How much does a survey cost?

Survey costs vary depending on:

• Project scope – Size and complexity.

• Survey type – Specific services required.

• Site conditions – Accessibility and location.

We provide bespoke quotes based on individual project needs.

How soon can you commence a survey?

We typically schedule surveys within one to two weeks, subject to availability and project requirements. Expedited requests will be considered on a case-by-case basis.
