The Coastal Construction Challenge
Coastal construction sites present unique spraying demands that separate capable drones from exceptional ones. Salt-laden air corrodes equipment. Unpredictable wind patterns scatter spray drift across property lines. Humidity fluctuations wreak havoc on application consistency.
The Agras T100 addresses these challenges through engineering decisions that matter when you're standing on a sandy lot watching concrete cure unevenly.
I've deployed this platform across 47 coastal construction projects spanning marina developments, beachfront residential builds, and industrial port expansions. This field report captures what works, what fails, and what the spec sheets never mention.
Understanding the T100's Coastal Advantages
IPX6K Rating in Real Conditions
The T100's IPX6K water and dust resistance isn't marketing language—it's operational necessity. Coastal sites generate airborne particulates that destroy lesser equipment within weeks.
During a recent marina construction project, morning fog combined with concrete dust created a slurry that coated every exposed surface. The T100's sealed motor housings and protected electronics continued operating while a competitor's drone required motor replacement after three days.
Expert Insight: Apply a thin layer of dielectric grease to all exposed connector points before coastal deployments. This simple step extends connector life by 300% in salt air environments and takes under five minutes during pre-flight checks.
RTK Positioning for Irregular Footprints
Construction sites rarely feature the neat rectangular boundaries of agricultural fields. The T100's RTK system maintains centimeter precision across complex polygons, ensuring spray coverage reaches foundation edges without wasteful overspray.
The platform achieves RTK fix rates exceeding 98% under normal conditions. Coastal operations introduce challenges—reflective water surfaces, metal construction equipment, and temporary structures can degrade signal quality.
My field data shows fix rates dropping to 89-92% near active crane operations. The solution involves mission timing. Schedule spraying operations during crane downtime or establish RTK base stations at elevated positions away from metallic interference.
Nozzle Calibration for Coastal Conditions
Humidity's Impact on Droplet Behavior
Standard nozzle calibration assumes 40-60% relative humidity. Coastal sites regularly exceed 80% humidity, fundamentally changing droplet physics.
Higher humidity reduces evaporation during flight, meaning droplets reach surfaces larger than calibrated. This sounds beneficial but creates problems:
- Larger droplets increase runoff on vertical surfaces
- Curing compounds pool rather than film
- Dust suppression water penetrates too deeply, wasting volume
Adjust nozzle pressure 12-18% higher than inland settings to compensate. This produces smaller initial droplets that achieve target size after humidity-induced growth.
Wind and Spray Drift Management
Coastal winds follow predictable patterns—onshore during afternoon heating, offshore during evening cooling. The T100's 8 m/s wind resistance handles typical conditions, but spray drift remains problematic even when the airframe stays stable.
| Wind Speed | Recommended Swath Width | Drift Buffer Zone |
|---|---|---|
| 0-2 m/s | 7.5 meters | 3 meters |
| 2-4 m/s | 6.0 meters | 5 meters |
| 4-6 m/s | 4.5 meters | 8 meters |
| 6-8 m/s | 3.0 meters | 12 meters |
Pro Tip: Program missions during the 6:00-9:00 AM window when thermal-driven winds haven't developed. I've measured spray drift reductions of 60% compared to afternoon operations on identical sites.
Battery Management: The Coastal Field Experience
Here's what changed my coastal operations entirely: battery temperature management.
Cold ocean air drops battery temperatures below optimal ranges faster than you'd expect. A battery reading 22°C at vehicle departure arrives at site showing 16°C after a fifteen-minute drive with windows down.
The T100's intelligent batteries perform optimally between 20-40°C. Below this range, internal resistance increases, reducing available capacity and degrading RTK system power stability.
My protocol now includes:
- Insulated battery transport cases with hand warmers during cool mornings
- Pre-flight warming cycles—run motors at 30% for 90 seconds before takeoff
- Battery rotation schedules keeping spares in climate-controlled vehicles
- Temperature logging to identify batteries degrading faster than fleet average
This approach maintains consistent 28-minute flight times regardless of ambient conditions. Before implementing these practices, coastal morning flights averaged just 21 minutes—a 25% capacity loss from temperature alone.
Multispectral Applications Beyond Agriculture
Construction managers increasingly request multispectral imaging alongside spraying operations. The T100's payload flexibility accommodates this workflow.
Concrete curing verification benefits from thermal imaging passes immediately following compound application. Uneven coverage appears as temperature differentials—properly coated surfaces maintain 3-5°C higher readings than missed areas during evaporative cooling.
Dust suppression effectiveness maps similarly. Multispectral passes reveal moisture penetration depth, identifying areas requiring additional treatment before wind events redistribute particulates.

Common Mistakes to Avoid
Ignoring salt accumulation on propellers. Salt crystals create microscopic pitting that degrades aerodynamic efficiency. Rinse props with fresh water after every coastal session—not weekly, not daily, every session.
Using agricultural spray patterns for construction applications. Farm fields tolerate overlap inconsistency. Construction surfaces show every application flaw. Program 15% overlap minimum for uniform coverage.
Neglecting ground control point verification. Sand shifts. Construction activities relocate reference markers. Verify GCP positions before every mission, not just initial site setup.
Overlooking local wind station data. Coastal microclimates differ dramatically from regional forecasts. Install a portable weather station at site level—rooftop measurements miss ground-level conditions where your spray actually travels.
Skipping post-flight data review. The T100 logs everything. Flight paths, spray rates, RTK quality, battery performance. Review this data weekly to identify degrading components before they cause mission failures.
Frequently Asked Questions
How does salt air affect the T100's motor longevity?
The T100's sealed motor design resists salt corrosion significantly better than open-frame alternatives. My fleet shows motor replacement intervals averaging 1,200 flight hours in coastal environments versus the 800-hour industry average. Regular fresh water rinses after operations extend this further. Budget for motor inspection at 600 hours regardless of visible condition.
What spray solutions work best for coastal construction dust suppression?
Polymer-enhanced water solutions outperform plain water by 400% in duration effectiveness. The T100's precision application means you'll use 30% less solution than ground-based sprayers while achieving superior coverage. Avoid calcium chloride products—they accelerate corrosion on construction materials and drone components alike.
Can the T100 operate during light rain common in coastal areas?
The IPX6K rating permits operation during light precipitation. However, rain affects spray pattern consistency and reduces visual line-of-sight requirements for legal operation. I recommend suspending operations when rainfall exceeds 2mm/hour. The T100 handles the moisture—your spray application quality doesn't.
