Capabilities / Site checks

Site checks

Whether you’re monitoring safety hazards, assessing road grades, or tracking changes over time, Propeller helps you perform quick site checks to help you stay on time and on track.
Road grade site check

Monitor your site activity

Measure your site progress and use real-time data to find any deviations from your site designs.

Keep your team safe

Locate and address damages, potential hazards, and safety concerns through regular site checks.

Keep a visual record

Use your 3D maps as proof of work, creating a visual timeline of the work you’ve completed.

Measure your site

The more often you check your site, the more accurate your updates will be. You’ll have a visual record of your team’s progress, allowing you to share with stakeholders and more accurately estimate completion times.

Site check features in Propeller

Propeller’s site checks empower users to keep record, stay safe, and move work forward with confidence.

Berm check

Measure safety berms, bunds, windrows, or other barriers to confirm that they meet design and safety requirements. Draw a line across the barrier to calculate height and width.

Safety hazards

Mark safety hazards and assign the severity level without doing a site walkthrough. You can mark these hazards with the media tool in Propeller, allowing your team to stay informed and safe.

Road grades

Measure a section of road, pavement, or track to calculate the grade as a degree, percentage, or ratio. Ensure your roads remain stable and secure.

Slope angle

Draw a line along any slope to calculate the slope angle in degrees, as a percentage, or a ratio. Use this tool to address safety concerns and mitigate environmental risks.

Elevation check

Mark features and points of interest on your site for easy record-keeping or sharing with your team. This could be hazards, utility lines, changed terrain due to weather.

Point of interest

Access Propeller from any device and download the mobile app to take maps into the field. Smart surveys put your worksite in your pocket.

Surface area

Get accurate surface area measurements within a polygon. Assess project milestones, monitor productivity, and make adjustments to stay on track.


Draw a line between two or more points to calculate the elevation difference between the points. You’ll get a snapshot view of the work done in that area.

Visual timeline

Get a visual tool that shows you every survey map in order. You can see an overview of the progress completed and provide updates to stakeholders at a glance.

Preferential flow path

View routes where water will flow more readily due to variations in soil or structure. Prevent erosion, flooding, or structural damage.

Liquid drop analysis

Measure the permeability of the soil on your site to spot any potential drainage or flooding issues.

Terrain cleanup

Remove objects you don’t want to measure from your map with just one click.

All your FAQs, answered.

According to the Occupational Safety and Health Administration (OSHA), sites should be checked weekly for safety issues.

Quick site checks contribute to safety on construction sites by locating hazards and compliance issues. These inspections allow teams to check on site conditions, equipment integrity, and worker behavior. Finding issues before they become big problems can keep your team safe and your project on track.

Yes, elevation site checks can identify elevation variations, which may indicate areas prone to water accumulation or flow problems. Early identification allows teams to implement drainage solutions that prevent damage. We recommend using our surface analysis tool to predict drainage and understand the hydrology of a worksite.

Absolutely! Quick slope site checks can help enhance safety, check on terrain stability, find any hazards, and see if any slope stabilization measures need to be used.
