Inventory of the Current Technical Condition of Infrastructure Facilities. 3D Scanning Technology – Capabilities and Limitations

The lack of technical documentation for underground infrastructure facilities is a common issue faced by all stakeholders in the investment process. For engineers, beyond written descriptions, technical drawings are of primary importance—but what can be done when such drawings are unavailable?
Traditional on-site surveys require precise work under specific conditions, are time-consuming, and may be challenging to perform. Laser scanning technology and the generation of point clouds offer a way to support this process using modern measurement instruments and IT solutions.
This presentation is not intended to promote any specific product or manufacturer, but rather to showcase practical engineering applications. Therefore, real-life examples of 3D scanning usage in the water and wastewater sector will be presented, along with a discussion of the actual capabilities of this technology.
We will explore how 3D scanning can be useful and—equally importantly—what its limitations are. In addition to its obvious use during the planning phase of rehabilitation projects, the technology can also be employed to document construction progress and as part of as-built documentation.
As such, it is a tool of interest not only to investors and network operators but also to designers and contractors.

Graduate of Warsaw University of Technology, Faculty of Civil Engineering, majoring in construction of building and engineering structures and postgraduate studies in trenchless technologies in environmental engineering at Kielce University of Technology. Designer with a licence to design in the construction and civil engineering specialisation without limitations.
For many years associated as a product manager for trenchless technologies and regional manager with construction chemicals manufacturer MC-Bauchemie Sp. z o.o., Co-founder of the Building Materials Laboratory at Centrum Badań i Certyfikacji Sp. z o.o., where he is responsible for the accreditation process and development of expert opinions. Currently, he also runs the TS Tomasz Szczepański Engineering Office, where he develops technical documentation on the diagnosis and assessment of the technical condition of reinforced concrete structures and renovation projects for water and sewage facilities and hydraulic engineering structures.
