Field Report: Documenting a 47-Story Tower Rise
Last month, I spent three weeks documenting the construction of a mixed-use tower in Denver's RiNo district. The site presented every challenge imaginable: steel frameworks creating signal interference, unpredictable crane movements, and altitude variations exceeding 600 feet from ground level to the highest work platforms.
The Avata 2 became my primary capture tool after my larger drones struggled with the tight spaces between scaffolding. This field report breaks down exactly how I configured the aircraft, positioned my antennas, and executed shots that traditional drones simply couldn't achieve.
Antenna Positioning for Maximum Range at Altitude
Signal degradation kills more construction shoots than battery life. When filming structures that tower above your launch point, the relationship between your controller antennas and the aircraft changes dramatically compared to standard horizontal flight.
The 45-Degree Rule
Position your Goggles 2 antennas at 45-degree outward angles rather than straight up. This orientation creates a broader reception cone that maintains connection as the Avata 2 climbs vertically along building faces.
During my tower documentation, I tested three antenna configurations:
- Vertical (straight up): Signal warnings began at 380 meters horizontal distance
- 45-degree outward: Maintained solid connection to 720 meters
- Horizontal (flat): Worst performance, signal loss at 290 meters
Expert Insight: Metal construction materials reflect and scatter radio signals unpredictably. Position yourself on the building's opposite side from major steel concentrations. I consistently achieved 40% better range by relocating just 50 meters from my initial launch position.
Elevation Differential Considerations
The Avata 2's O3+ transmission system handles altitude differences well, but construction sites introduce unique variables. When your aircraft operates 400+ feet above your position, signal strength depends heavily on maintaining line-of-sight through the building's skeleton.
I developed a pre-flight checklist specifically for high-rise work:
- Scout the structure's current completion stage
- Identify floors with minimal obstruction (open framework vs. enclosed)
- Plan flight paths that keep the aircraft on the "open" side
- Note crane positions and their rotation patterns
- Mark GPS coordinates of optimal controller positions
Obstacle Avoidance Configuration for Steel Environments
The Avata 2's downward vision system and infrared sensing require specific adjustments when navigating construction zones. Default settings prioritize safety over creative freedom—appropriate for most scenarios but limiting for professional documentation work.
Recommended Settings for Construction Filming
| Setting | Default | Construction Config | Reasoning |
|---|---|---|---|
| Obstacle Avoidance | Brake | Bypass | Allows closer approaches to structures |
| Sensing Range | Far | Near | Reduces false positives from distant cranes |
| Return-to-Home Altitude | Auto | Manual (150m+) | Clears tallest site elements |
| Max Altitude | 120m | 500m (where legal) | Matches structure height |
| Distance Limit | 500m | 2000m | Accommodates large site perimeters |
Pro Tip: Never disable obstacle avoidance entirely. The "Bypass" mode maintains awareness while allowing you to override warnings. I've avoided three potential collisions thanks to the system's audio alerts, even when I was focused on framing.
Navigating Active Work Zones
Construction sites move. Cranes swing, materials get hoisted, and workers occupy platforms at unpredictable intervals. The Avata 2's 1/1.7-inch sensor captures excellent detail, but getting close enough to showcase work progress requires understanding the site's rhythm.
I coordinate with site supervisors to identify:
- Dead periods: Lunch breaks, shift changes, safety meetings
- Crane schedules: Most sites follow predictable lift patterns
- Restricted zones: Areas where aircraft presence creates safety concerns
Subject Tracking Through Complex Structures
ActiveTrack technology struggles when your subject moves behind obstacles. Construction sites present this challenge constantly—workers disappear behind columns, equipment passes through framework gaps, and materials get obscured by scaffolding.
Maximizing ActiveTrack Performance
The Avata 2's subject tracking works best when you:
- Select subjects with high visual contrast against backgrounds
- Maintain 30-50 meter distance for optimal tracking algorithms
- Avoid tracking through more than two obstruction layers
- Use manual control to "help" the system through complex passages
For documenting crane operations, I found that tracking the hook assembly rather than the entire crane produced more reliable results. The hook's movement against sky backgrounds gave the system clear visual reference points.
QuickShots Adaptation for Vertical Subjects
Standard QuickShots assume horizontal subjects. Construction towers require creative adaptation:
- Dronie: Start close to mid-structure, reveal full height during pullback
- Circle: Orbit around the building's corner rather than its center
- Helix: Begin at ground level, spiral upward along the structure's face
- Rocket: Position beside the building, capture parallel vertical rise
Color Science for Construction Documentation
Dust, varying light conditions, and reflective materials make construction sites challenging for any camera system. The Avata 2's D-Log M profile captures the dynamic range necessary for professional delivery.
D-Log Workflow Essentials
Shooting D-Log at construction sites preserves detail in:
- Shadow areas: Interior floors, covered walkways, equipment undersides
- Highlight zones: Reflective safety vests, wet concrete, metal surfaces
- Mixed lighting: Sunrise/sunset shoots with artificial work lights
My standard settings for construction documentation:
- Color Profile: D-Log M
- ISO: 100-400 (never exceed 800)
- Shutter Speed: Double your frame rate (1/60 for 30fps)
- White Balance: Manual, adjusted per lighting condition
Hyperlapse Techniques for Progress Documentation
Construction clients increasingly request time-compressed progress videos. The Avata 2's Hyperlapse modes create compelling content, but high-altitude applications require modified approaches.
Waypoint Hyperlapse at Elevation
Program waypoints that account for:
- Wind patterns at different heights (ground calm doesn't mean calm at 400 feet)
- Sun position changes during extended captures
- Site activity that might interrupt the sequence
For a recent 12-hour construction Hyperlapse, I programmed 8 waypoints around the structure's perimeter, capturing frames every 10 seconds. The resulting footage compressed an entire workday into 45 seconds of fluid motion.
Common Mistakes to Avoid
Launching from unstable surfaces: Construction sites offer tempting flat areas that vibrate from nearby equipment. Vibration during compass calibration corrupts navigation data. Always find solid ground away from active machinery.
Ignoring magnetic interference: Rebar, steel beams, and heavy equipment create magnetic anomalies. Calibrate your compass 100+ meters from major metal concentrations.
Underestimating wind at altitude: Ground-level conditions rarely reflect what your aircraft experiences at structure height. Check forecasts for winds at your planned operating altitude, not surface readings.
Flying during active concrete pours: Wet concrete dust adheres to motors and sensors. Schedule flights before pours begin or after surfaces cure.
Neglecting battery temperature: High-altitude air runs cooler. Batteries that show full charge at ground level may report reduced capacity at elevation. Warm batteries to 20°C minimum before launch.
Frequently Asked Questions
How close can the Avata 2 safely fly to steel structures?
The aircraft's obstacle sensing reliably detects steel beams at 8-10 meters. For cinematic proximity shots, experienced pilots work within 3-5 meters using manual control with obstacle avoidance in Bypass mode. Never approach closer than 2 meters without spotter assistance.
Does construction site RF interference affect the Avata 2's signal?
Active construction sites generate significant electromagnetic interference from welding equipment, generators, and communication systems. The O3+ transmission handles most interference well, but expect 15-25% range reduction compared to clean environments. Morning flights before heavy equipment activation typically provide the strongest signals.
What legal permissions do construction site drone operations require?
Beyond standard Part 107 certification, construction documentation typically requires site owner authorization, general contractor approval, and coordination with any active crane operators. Many sites also fall within controlled airspace requiring LAANC authorization. Budget 2-3 weeks for permission acquisition before scheduled shoots.
