Construction Site Monitoring & Orthomosaics for a Large Development

Services used:

• Monthly aerial flights for construction progress monitoring (Construction Site Monitoring)

• Generation of high-resolution orthomosaic maps (Orthomosaics & Aerial Survey)

• Data Capture & Analysis: Area calculations, volumetric estimates, change detection over time

Challenges:

• Large and remote site; terrain includes sugar-cane fields, partially built infrastructure.

• Need to keep stakeholders (developer, investors, local authorities) updated with visual data.

Solution by TideWatcher:

• Set up repeated drone flights (same flight plan monthly) capturing high-resolution imagery and video;

• Process imagery into orthomosaic maps (pixel size < 4 cm) for master-plan support and construction tracking.

• Provide analytics: e.g., area cleared, volume of earthworks done, comparison vs previous month, highlight deviations from plan.

• Deliver visual progress reports and interactive 3D models for stakeholder review.

Results:

• The developer had up-to-date bird’s-eye view of progress, enabling early detection of delays or deviations.

• The orthomosaic maps allowed quantification (area/volume) and improved transparency with financiers.

• Time saved compared to ground-based surveying and site visits.

Key take-aways:

• Monthly cadence ensures comparable imagery over time.

• Orthomosaics are powerful deliverables in construction monitoring.

• Emphasise “island-wide service” (as your site claims) to reassure clients of reach across Mauritius.
