Frequent site surveys give you the opportunity to spot hazards and detect irregularities, fissures, and potential slips, before they become a problem. 

You can use safety-focused templates in Propeller to create a paper-free, precise visual record of site hazards, road grades, and berm heights that can easily be tracked and shared with your team. 


How to measure berm heights

A common safety check is to use the line tool to measure berm heights. 

To do this you will need to select the template called Safety Berm Check. Head to measurements in the left-hand tab and select the line tool. From here you will see the dropdown list which includes the Safety Berm Check template.

To use this template it’s as simple as clicking once at the high point of the berm and double-clicking at the base of the berm. You can visualize the measurement in 3D and change the color of the measurement to indicate higher safety risks in the left hand panel. 

You can also select the Severity and Likelihood to capture vital safety information in the dropdown lists. Make notes or add comments about specific hazards to help provide additional context when sharing with your team.

How to measure road grades 

Another routine safety check Propeller customers often do, is to measure road grades on a site. For this measurement you will need to select the template Safety Road Gradient under the line tool.

Simply click along the road you want to measure and double-click to finish. You can measure the grade of the road in percent, degrees, or a ratio.

How to use the Gradient Layer to check all roads on site 

The Gradient Layer is another feature we can use to evaluate a site for safety hazards. 

Since most roads are not steeper than 40%, we can customize the gradient ranges to easily highlight all the roads on the site. When those changes are applied, you can quickly visualize the roads and zoom in to specific areas for further evaluation. 

You can find more detailed information on how to customize the Gradient Map to check for steep roads here.  

How to mark and log a specific hazard on site 

In order to mark specific hazards on a site, you can use the point tool and select the Safety Hazards template. 

Marking the area of the road that was too steep is as simple as clicking at that location. You will automatically get coordinates of that location, as well as dropdown lists to capture safety information.

Highlight safety hazards using the Polygon and Line Tools

Use the Polygon tool to quickly draw a boundary around areas on site, like the visitor car park, or to mark out slow speed zones. These areas can easily be kept up to date by adjusting the boundaries using the latest drone survey, and, because it can be promoted to Site level, you can make this easily visible for the whole team to see. 

You can also use the Line tool to mark out areas like open trenches and roads with steep gradients that others should be made aware of.

How to export and share safety hazards with your team. 

Finally, easily share all of the safety-related measurements you’ve created with key stakeholders and team members.  

Notify others of a site hazard by email, or sharing a link. 

To quickly let others know about a potential hazard on site, click the Share icon once you’ve created and saved your annotation. When clicking the link, recipients are taken directly to the hazard shared with them.

Export and share safety hazard reports 

To export and share a report specific or all safety hazards, search for “safety” in the search bar in the left-hand panel to bring up a up related measurements. 

You can select the measurements you want to share and generate a report that can be exported in PDF or CSV format. To create the report, click reports in the top left of the screen. A PDF report includes an overview of each measurement as well as the specific information you added, like comments or severity information.
