Trenchless Construction session
Preliminary presentation plan: The paper will describe conditions for the implementation of gas transmission pipeline networks using microtunnel technology in sections crossing terrain obstacles trenchless. Guidelines for the installation of steel drill pipes on w/c for long and short microtunnels will be presented, together with requirements for the installation of steel pipes in casing pipes. Recommended technologies for the implementation of short crossings under obstructions for pipes up to 500 mm in diameter will also be discussed. The presentation will discuss the latest developments based on digitisation and automation as well as technical solutions that have a real impact on ecology, comfort and simplicity of use, precision and safety when working with trenchless technologies. Today, in an era of intense energy and climate transition, low-environmental impact technologies are becoming the cornerstone of modern linear infrastructure. Trenchless methods such as HDD or Direct Pipe allow underground networks to be constructed with minimal interference with the landscape, soil and natural habitats. Nevertheless, their use in practice is sometimes limited by rigid and ambiguous legal frameworks. The following issues will be addressed during the discussion:

Environmental directives - a barrier or an opportunity for the development of low-invasive trenchless technology
The aim of this study was to identify and analyse the legal and environmental barriers to the use of trenchless technologies in areas of natural value - especially Natura 2000, peatlands and river valleys. Selected EU legislation was analysed, including the Habitats Directive (92/43/EEC), the Water Framework Directive (2000/60/EC), the EIA Directive (2011/92/EU), the Taxonomic Regulation (EU 2020/852) and the Nature Restoration Law (2023/2195). Clashes between records (EIA - Environmental Impact Assessment) and actual environmental impacts of selected technologies were also analysed.
The work identified the need for dedicated environmental guidelines for trenchless technologies and their formal recognition as preferred techniques for linear projects, among others. It was also proposed to start work on their inclusion in the BAT (Best Available Techniques) system, which could be a breakthrough in the decision-making process for environmentally sensitive infrastructure investments.

Trenchless Renovation session
Tests carried out directly on objects or in laboratories on samples taken are the basis for assessing their technical condition. At present, a number of testing methods are available on the Polish market that enable a reliable assessment of the structure, including the material from which it is made. The paper will present the possibilities of using the observation method and digital twins during the implementation of trenchless techniques and the operation of underground critical infrastructure. The assumptions of the idea of digital twins and an evaluation of the possibilities of their use over the last several years will be discussed. The principles of the observation method for the realisation of linear structures will be presented and the evaluation from CAD (2D drawings) to the Digital Twin. A method will be discussed which can be used to integrate the geometry of the facility, the condition assessments and the monitoring results of the underground infrastructure and its surroundings in order to ensure the safety of the installation and to determine the optimum time to start repairs or upgrades. This is particularly important in urban areas with time-varying loads and changes in soil and water conditions, as well as in areas of mining damage. 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? A unique contract - the first of its kind in Poland. Due to the variety of collector shapes, materials, sewage flows and locations, five sewer rehabilitation technologies were used including, relining with short full GRP pipe modules, relining with spiral wound pipe, lamination and repair using construction chemicals in combination with GRP modules. Many organisational challenges during the design, agreement and execution of the works. Trenchless rehabilitation of DN1400, DN1600, DN1800, DN2000 circular and non-circular collectors - 1900×1900 square and G1800x2250 pear profile with a total length of over 3.5km of sanitary sewer in complex locations on the right bank of Warsaw. One of the largest refurbishment contracts of recent years in Poland shown briefly based on a construction film and animations of selected execution technologies.

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