Topographic Survey for Pago Bay Apartment

Topographic survey for apartment development

Client

America's Best Electric Mart (ABE)

Project Type

Topographic Mapping

Location

Pago Bay, Guam

Project Overview

The owners of America’s Best Electric Mart (ABE) planned to develop an apartment complex in Pago Bay, Guam and required a detailed topographic survey to proceed with the project.

Recognizing the challenges of securing survey services on Guam, 2cofly partnered with licensed land surveyor Gavino Estur to provide a fast and efficient aerial survey solution.

By leveraging drone technology, we helped accelerate the survey process, allowing the developers to obtain critical land data in a fraction of the time traditional methods would have taken.

The Challenge

One of the biggest hurdles for developers in Guam is the availability of surveyors. Due to high demand and limited resources, securing a professional surveyor can take months—delaying construction timelines and increasing costs.

ABE needed accurate elevation data to proceed with site planning, but waiting for a traditional survey could have significantly slowed down their project. The challenge was to speed up the surveying process while maintaining high accuracy and compliance with regulatory standards.

Approach & Methodology

Drone-Based Aerial Mapping2cofly deployed high-resolution aerial photogrammetry and LiDAR scanning to capture detailed elevation data across the project site. By using drone technology, we eliminated the need for extensive manual surveying while covering the entire area in a single flight mission.

Surveyor Collaboration for AccuracyTo ensure compliance with local regulations, we partnered with licensed surveyor Gavino Estur, who provided ground control points (GCPs) and validated the final survey results. This collaboration ensured the deliverables met all required engineering standards.

Deliverables

Topographic Survey Map – Engineering-grade elevation data for site planning
High-Resolution Orthomosaic Map – Up-to-date aerial imagery of the development site
Digital Elevation Model (DEM) – 3D terrain model for precise land analysis

Results & Project Impact

Significant Time Savings

By integrating drone technology into the survey process, we helped cut delivery time from months to just a few weeks, allowing the developers to move forward without unnecessary delays.

Increased Efficiency for Surveyors

Traditional land surveys require extensive fieldwork and data processing, but with drone assistance, the licensed surveyor was able to complete the mapping process much faster while maintaining industry-standard accuracy.

Accurate & Actionable Data

The high-resolution topographic survey provided the necessary insights for grading, drainage planning, and foundation design, ensuring the project could move forward with confidence.

Conclusion

This project highlights the growing need for drone-assisted surveying solutions in Guam’s construction and development industry. By combining 2cofly’s advanced aerial mapping capabilities with licensed survey expertise, we successfully streamlined the surveying process, reducing delays and enhancing efficiency for developers.

For projects requiring fast, high-precision topographic surveys, LiDAR mapping, or aerial site assessments, 2cofly provides cost-effective and time-saving solutions that help businesses move forward with confidence.
