Process of Verification of Earthworks Execution Using Terrestrial Laser Scanning

Abstract

Interactive verification of construction works should provide for compliance between planned vs. completed works. The task of its fulfilment (especially for larger investment projects) is rather time and labor consuming. There is potential to reduce the duration of a verification process as well as to ensure the results are more accurate and clear with the use of digital tools and specialized software, moreover, substantial part of the process may be automated. Faster and more accurate capturing of a data regarding actual position and shape of the construction works, resp. its parts, as well as the information about the quality of works has the potential to reduce number of disputes caused by unclear measurement data evaluation. The technology of Terrestrial Laser Scanning (TLS) is suitable for this purpose allowing efficient data collection and automation of the process of verification. The article provides a case study comparing traditional approach vs. use of TLS for earthworks verification and the impact of different methods of measurement on the price.
