Propeller Reports: Getting the Right Information in Your Hands at the Right Time

| 21.07.2022

In earthworks, tracking your material quantities is crucial, whether you’re removing topsoil, cutting material and stockpiling it to be used as fill, or adding engineering materials such as road base. Knowing how much you have allows you to determine if you have the appropriate amount of earth to complete a project, or if you need to dispose of excess material.

Accurate reports generated from a drone surveying software solution like the Propeller Platform help earthworks and construction teams plan their projects, track material inventories, and monitor progress. Here, we’ll walk you through some common workflows that earthmoving businesses can report on using their drone survey data processed by Propeller.

Progress reporting

Calculating how much work you have completed and how much work is left to do can be accomplished in a variety of ways within the Propeller Platform using the volume comparison tool. This tool compares two surfaces to each other (more here). Capabilities include:

  • Comparing the current surface to the original surface – Normally the surface that earthworks contractors are comparing to is the bare earth or a stripped surface, that is, after all the vegetation and other items have been removed from the worksite. You can use this way of reporting to determine how much material you have moved since the beginning of your job and if you are tracking correctly against your project milestones.
  • Comparing the current surface to the last surveyed surface – This type of comparison is generally done in weekly, bi-monthly, or monthly intervals to learn how your site has changed since the last reporting period. Project managers or superintendents will use this information to understand how quickly/slowly the site is progressing and determine if re-deploying people or equipment may be needed. They will also use this comparison to determine how much they should be compensated for the material they’ve moved or what they may need to pay a contractor.
  • Comparing the current surface to the final design – When the final project design is a subgrade surface, this is the point where earthworks ends and material, such as asphalt or concrete is then laid. This comparison allows you to track how close you are to the earthworks completion for the project.

Other ways to track progress

Generally, project managers will choose a measurement tool from which to work, such as the progress tracking template that allows the user to combine two volume comparisons in one measurement. Users can also visualize how their site has changed over a specific period and what material is left to move by using the cross section tool. This allows you to create a cross section directly through your site and observe how your current drone-surveyed surface interacts with different layers. It’s explained here in this video

Takeoff reports can also be used to help visualize and share how much material remains to be moved with respect to your initial design.

Exportable reports

Within the Propeller Platform, you can choose from multiple reports to export data that gives project foreman and supervisors a better understanding of their site’s condition. These include:
