What's in the app

Built around location. Not bolted onto it.

Every feature starts at the station. That's what makes the documentation hold up.

Most-used feature

Station Finder

Open the app. See your station, offset, and design layer instantly. No stakes. No survey wheel. No call to the PM.

Live station and offset, GPS-driven
Alignment locking, jumping, MM/LRS conversions
Design layer overlays — CAD, traffic control, utilities
Offline mode for dead zones

Mathy Construction: $18,000 saved per density technician per season — 2 hours back on every shift.

Coordination

Flag & Chat

Drop a flag at any station. Start a conversation tied to that location. Everyone on the project — your crew, the inspector, the prime, the DOT — sees the same thread.

Flags pinned to station and timestamp automatically
Photos and notes attach to the flag, not a group text
Group chats by project, alignment, or crew
Shared with subs, inspectors, and DOT staff

RS&H, I-4 corridor: a guardrail location dispute resolved in seconds — instead of hours of paper-pulling.

Documentation

Camera Notes

Every photo gets stamped with the station, alignment, date, and time — automatically. The kind of documentation that holds up in a pay-app dispute or a DOT audit.

Auto-tagged to station, offset, and alignment
Date- and time-stamped
Searchable in the Data Portal
Tag by category — rework, change order, safety

Hoffman Construction: 3 utility strikes avoided on a single project — caught with overlay-tagged photos.

QC & inspection

Forms

Custom field forms — density tests, inspection checklists, daily diaries — filled out on the phone, locked to the station they were captured at. Data flows into the Data Portal and your existing tools.

Custom fields for any test or daily report
Location-locked to the station of capture
HCSS HeavyJob daily diary populated automatically
Trimble, TransTech, FleetWatcher, GNSS integrations

Iowa DOT: 9,077 flags dropped across 200 projects — 16 contractors voluntarily adopted the standard.

Safety

Active Worksite™

Built into the same app. Shares your crew's live location with the traveling public — drivers get alerted only when approaching active personnel, not a static work zone sign. One in five construction fatalities happen in highway work zones.

Real-time alerts to drivers near active crew
Works on any phone the crew already carries
No extra hardware. No separate app.

Real numbers. Named customers.

No rovers

GPS rover dependency eliminated. Inspectors stopped waiting on borrowed equipment.
