DRONES IN

CONSTRUCTION

Construction is one of the newer industries in the introduction of drones has greatly lowered costs and facilitated time-management. Often resulting in safer, more efficient and dependable practices UAVs are becoming more widely adopted and their uses are multiplying.

 

The categories below are just some of the current opportunities in which drones are value-adding.

 

 

 

Location Accuracy

 

Drones can now make 3D maps that are accurate to within 2-5 cm horizontally and 4-8 cm vertically*. These maps allow us proof of location with a high degree of precision:

  • Comparative analysis: as-planned vs as-built

  • Verifying two separate pieces are at the same height and will be level

  • Locating specific points once the landscape is dug up and unrecognisable

 

 

Resource Management

 

Whether it’s misplaced equipment or large stockpiles that need to be moved, drones can locate and calculate materials quickly. In certain cases, UAVs can be used to count certain elements (for example: calculating how many thousands of studs).

 

 

Progress Reports

 

Because making a map site with a drone is fast and not resource-intensive, it is reasonable to map a work site at regular intervals. On top of having an updated map which eases operational planning and communication, newer maps can also be cross referenced with older ones for a host of benefits.

 

  • Errors can be found with more ease fixed earlier on in a project

  • Data exists to aid in any disputes with contractors about what was done when

  • Vital information is catalogued about the different stages of the project

 

 

 

 

Major construction projects that have fully embraced the services that drones can provide them are coming in under-budget and/or without delays, sometimes even ahead of schedule. They are quickly becoming an invaluable tool for mapping, managing, and inspecting large scale construction projects.

 

 

 

 

* To achieve this accuracy, specifically marked points must first be calculated by a professional surveyor.

Earthwork Example

 

Using a drone to make a new map every week during earthwork could provide accurate and up-to-date elevation maps and volumetric calculations for on-going stockpiles and for any cut and fill work. Having access to the big picture of the overall site during this vital stage can make all the difference in avoiding costly mistakes (for example: drainage issues).
