“Without the platform, we would need to at least double the size of the team to achieve the same level of accuracy and speed.”
– Paulo Eduardo Palma Baptista, Construction Coordinator, Nova Rota do Oeste
Deliver on budget. On schedule. On record.
The confidence to manage every phase with high-precision data at your fingertips. From Day 0 baseline to final as-built.
Project managers carry the weight of every cost overrun, schedule slip, and rework event. Propeller gives you a single source of truth across your entire site so you can track production against plan, protect your margins with change order documentation, and close out every phase with an airtight paper trail.
Stop managing in the dark
Turn site bottlenecks into predictable milestones. Here’s how Propeller bridges the gap between the field and the office.
Budget surprises from inaccurate baselines
Start with high-precision ground truth to avoid Day 1 dirt surprises that weren’t in the estimate.
Rework that eats margin and schedule
Verify work continuously, not retroactively. Catch grade errors before they become permanent.
No reliable paper trail when dispute arises
Replace costly disputes with a factual conversation backed by timestamped, high-precision data.
Chasing the field for progress updates
See daily production data from your desk without waiting for a foreman’s “gut feel.”
Change order disputes
Propeller makes every cubic yard defensible. If you can’t prove the ground moved, you can’t bill for it.
We let the data and our customers do the talking
“We had three or four very large utility conflicts. We had a 16-inch water main cutting through the site that was in the wrong location [and] the main power feeds for the airport cutting through the site that were in the wrong location.”
– Brian Holm, Project Superintendent, Hensel Phelps
“We began using it on the project to capture weekly project photos for the client and to keep track of the quantities of waste materials we had to move around the site, as we began reprofiling the landfill. We created a model of the existing landfill and then we were able to generate a cut/fill balance against the final project design. We were then able to track that regularly and see how we were progressing on the project.”
– Jonathan Wills, Director, Wills Bros
Your role across every phase
Propeller isn’t a point solution. It’s a command center that connects your office to the field.
Existing ground capture
Lock in a defensible baseline before the first machine turns. Verify bid quantities and build your plan on ground truth, not assumptions.
Progress tracking
Track cost and bid schedule in real time. Surface production data to protect profit margins and build the documentation trail for change orders.
Design conformance + as-built verification’
Eliminate expensive rework by verifying site progress against design. Deliver quality control your team and client can stand behind.
Safety + agency compliance
Build an automatic digital paper trail of timestamped surveys and records ready for audits and disputes without extra admin overhead.
Field to office, office to field
Stop chasing field updates. Push design intent to the field and pull real-world data back to the office so decisions are based on what’s actually happening.
The tools that run your site
We’ve curated the Propeller toolkit into three core areas that help Project Managers maintain control from groundbreaking to closeout.
Track progress and schedule
Timeline
Visualize exactly how your site has changed over time between survey captures to keep the schedule on track
Surface-to-surface comparisons
Quantify the difference between any two survey surfaces to measure material movement in seconds
Progress tracking
Get high-frequency production snapshots without waiting on traditional survey reports
Measurement Report
Create customizable PDF or CSV reports of your site data to keep stakeholders informed
Verify quality and design conformance
CAD and design overlays
Overlay your design files directly on high-precision 3D data to spot deviations before they become rework
Grade Check
Assess grades as degrees, percentages, or ratios at any point on-site to verify accuracy in real time
Heatmaps and cross section analysis
Identify over- and under-excavation at a glance across your entire site footprint
Takeoff Map
Generate detailed reports comparing your current surveys with design surfaces to ensure you’re building to the model.
Protect + document
Markup and annotations
Add, style, and share labeled points and notes on the map in real time for better field alignment
Reporting and data exports
One-click exports for professional closeout packages, regulatory audits, and client sign-off
Media and 360 photography
Pin images and 360 photos to exact locations on the map for a permanent, timestamped visual record
Hydrology and surface runoff
Map water flow directions and identify catchment areas to ensure environmental compliance
Built for the way you build
One map to connect it all. No matter your sector, Propeller provides the high-precision data you need to manage risk and protect your margins.
Civil construction
Manage grade compliance, schedule adherence, and subcontractor billing.
Mining
Verify plan adherence, overburden removal, and blast subcontractor accountability.
Quarry + aggregates
Optimize pit efficiency and reconcile production volumes against sales tickets.
Waste management
Track new cell construction, airspace optimization, and liner verification.
Transportation
Maintain corridor accuracy and track linear progress against the bid schedule.
Surveying + engineering
Support as-built verification and deliver topo documentation for the engineer of record.
Frequently Asked Questions
Most PMs fly weekly to maintain a steady production cadence, but high-volume sites often capture data two to three times per week. Because Propeller processes data in hours, not days, you can make decisions based on what happened yesterday, not last month.
Absolutely. You can export professional PDF reports, generate shareable links, or use the Crew feature to share a mobile-friendly map via a unique URL.
Every capture is timestamped and high-precision. By comparing your “day 0” baseline to current conditions, you can generate a defensible volume report that proves exactly how much material moved. It turns a dispute into a factual conversation.
You do. We’re just the stewards of your data. You can export your raw files, processed surfaces, and reports at any time.
When used with AeroPoints or our PPK workflow, Propeller delivers 1/10ft (3cm) vertical accuracy. It’s high-precision data you can confidently use for topo surveys, volume reconciliation, and verifying design conformance.
Not at all. We handle the heavy lifting of the data processing for you. If you can navigate a web browser, you can use Propeller to measure volumes and track your timeline.
