Deliver on budget, on schedule, and 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. Construction progress monitoring in it’s purest form.

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.

“With access to more frequent, faster surveys, I am able to determine whether projects are running on schedule. It makes everything from budgeting to resource logistics to subcontractor scheduling a more precise operation.”
– Project Manager at Integrated Sustainability
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.

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.
