What is Construction Surveying?
Construction surveying plays a critical role in guaranteeing the success of any construction project, from ensuring accurate site measurements to providing data for design and planning. Construction surveying involves: construction setting out (which is the process of marking on site the construction design in the correct position), as-build surveys that can be used for different purposes like topographical maps, quantity calculation and site progress, and different other dimensional control and checks depending of the type of project.
The use of unmanned aerial systems (UAS's) in construction surveys, especially in as-built surveys is rapidly gaining popularity in the construction industry, offering increased cost and time efficiency, and safety over traditional surveying methods. The use of drones in construction surveying will be covered in this article, along with the benefits, applications, and essential considerations you should keep in mind.
What is the drone surveying process?
In big lines the drone surveying or drone mapping process starts with planning the flight path for the drone, taking into account the size and shape of the site, as well as any potential obstacles or hazards. The drone will then be launched and flown over the location to collect data and high resolution aerial photos using its built-in cameras and sensors. The drone's data will be uploaded to specialised software when the flight completes so that it can be processed and generated into 2D and 3D maps and models.
What type of drones are used in construction?
Drones can be utilised in construction projects in a variety of ways, each with special advantages and capabilities.
Fixed-wing drones are ideal for large scale surveying and mapping projects, as they can cover large areas quickly and provide highly accurate data.
Multi rotor drones are extremely manoeuvrable and can be utilised for more detailed monitoring and inspection duties, like inspecting the condition of bridges or structures.
Hybrid drones combine the advantages of both fixed-wing and multi rotor drones, are also becoming increasingly popular for construction projects. They combine the long range of fixed wing drones with the manoeuvrability of multirotor drones.
What are the advantages of using drone in Construction Surveying?
Drones offer numerous advantages over traditional surveying methods in construction. One of the most significant benefits is their increased accuracy and precision – drones can capture data with a centimetre accuracy, providing highly detailed and reliable site data collection. Additionally, drones offer improved efficiency and speed, allowing surveyors to cover larger areas and capture data more quickly than traditional surveying methods. This can help save time and money on construction projects, allowing for faster project completion and reduced surveying costs, by reducing the staff needed for data collection. Drone use in construction surveying can also increase surveyors safety because it eliminates the need for surveyors to work in dangerous or unsafe areas and allows them to fly the drone from a safe distance.
What factors you should consider when using drones in Construction Surveying?
While drones offer many advantages in construction surveying, there are also important factors to consider when implementing this technology in your project.
One key consideration is the legal and regulatory requirements – drone use is subject to various regulations and restrictions, including permits, certifications, insurances and airspace restrictions.
To assure the precision and dependability of drone data, technical issues including flight planning and data processing are crucial.
Personnel training and qualification are also crucial because drone operators need to be knowledgeable and skilled in order to operate the drone in a safe and effective manner.
Finally, cost considerations is very important because professional drones, software, insurance and personnel training comes with a considerable price and return of investment analysis are critical to determine whether drone surveying is a cost-effective solution for your construction project.
By carefully considering these factors, you can ensure a successful implementation of drone technology in your construction surveying process.
Conclusion
The use of drones in construction surveying offers numerous advantages over traditional surveying methods, including increased accuracy, efficiency, and safety.. However, implementing drone technology in your construction project requires careful consideration of various factors, including legal and regulatory requirements, technical considerations, personnel training, and cost analysis. By addressing these factors and planning a comprehensive drone surveying strategy, construction professionals can leverage the power of drones to improve their surveying processes and enhance project outcomes. In the near future, we may predict drones playing a growing importance in construction surveys as the technology develops and becomes more commonly used.
