There are some major advances in technology on the horizon which promise to make underground construction and maintenance significantly faster, cheaper, safer, less disruptive and more environmentally friendly. Approaches to underground construction have broadly remained the same for well over a century, meaning projects continue to have high levels of risk, complexity and cost, as well as a heavy carbon footprint. However, hyperTunnel & Michigan presents a new method of underground construction that is gaining traction –using the power of swarm robotics and in-situ construction to transform the traditional tunnel boring process.

A paradigm shift in subsurface assets development and management- Trenchless activities are generally performed in subsurface environs, where the created utilities are buried. Pre-existing utilities pose challenges for trenchless technologists, as what is buried is out of sight, and that way out of mind. If one is not aware of the presence of such utilities, possibilities are that the machine could damage the utility. To reduce these challenges subsurface utility mapping is the most effective solution. In this direction, IndSTT has published the Code of Practice for SUE and the session shall be discussing this code and essential competencies to prepare and certify Subsurface Utility Maps.

As urbanization increases, municipalities are faced with growing demands for efficient cities and better infrastructure. At the same time the effect of global warming is becoming more evident. Each year the number of natural disasters and economic cost of damage from these disasters increases. The change in weather patterns due to climate change has made it increasingly difficult for engineers and urban planners to design and maintain underground infrastructure. For over 50 years, trenchless rehabilitation has existed for municipalities to repair and maintain its underground infrastructure with minimal or no trench requirements. Cured In Place Pipe was one of these earlier technologies, traditionally using a felt carrier with a heat cured exothermic resin. Advances in carrier technology has now allowed CIPP with fiber reinforced for higher mechanical properties, different weaves for bends and transitions. Advances in resin technology to incorporate different curing methods from ambient cure to light cured resins. These innovations will allow rehabilitation to be adopted in more complex networks and increasingly difficult site scenario. Making it a growing segment in construction and ideal for municipalities looking for sustainable methods to improve their infrastructure. This paper will discuss developments in lateral rehabilitation, innovations in light curing technology for larger diameter trunk mains and sealing techniques in manholes. It will also touch on the need for accountability standards in the industry.

The presentation will focus on UV-CIPP technology's role in addressing current wastewater challenges. It will compare trenchless technology with traditional open-cut methods, highlighting the benefits of UV-CIPP. The installation process of UV-CIPP liners, utilizing UV light for resin curing, will be explained. The presentation will conclude with impactful case studies showcasing the successful implementation of UV-CIPP in various wastewater projects.

Gyro mapping is rapidly becoming a widely accepted technology for obtaining accurate XYZ data of subsurface utility infrastructure. Whether through national regulation or the utility network owners’ diligent network management policies, gyro mapping is becoming a standard new-build specification, in particular for trenchless installation methods. In addition, Utility network owners see a great benefit in having an objective and accurate as-built profile during the hand-over process with infrastructure contractors. But besides accurate XYZ, gyro-mapping has a number of advantages over traditional mapping that make it the more suitable and/or desirable technology in existing networks as well. On such aspect is the sampling frequency of 100Hz, or 100 samples per second. High frequency data enables accurate and highly detailed calculations of bend radius and grade measurement. Another key benefit is that gyro mapping is not affected by electromagnetic noise, so it can be used right next to typical EMS sources such as high-voltage cables, rail tracks and sheet piling. This presentation will introduce the audience to the concept, operational method, and data output of gyro mapping technology.

The SEKISUI CHEMICAL Group continue to develop the frontiers of "Creation of Housing/Social Infrastructure" and "Chemical Solutions," utilizing its prominent technology and quality, thereby contributing to people's lives around the world and the global environment. As the underground infrastructure ages around the world, it is essential to improve the structural integrity of the existing sewer network in a sustainable way. Machine Spirally Wound Lining (MWSL) is one of the leading trenchless technologies for sewer pipe rehabilitation. It is applicable not only for circular pipes but also for box culverts and other odd shapes. This presentation will provide a basic understanding and advantages of Spirally Wound Lining. Challenging case studies using Spiral Wound Lining from around the world will be shared. The Machine Spirally Wound Lining (MWSL) process is one such solution, employing a rigid PVC profile strip with an integral steel reinforcement band together with a structural grout in order to provide a composite structure capable of withstanding the applied loads. The system offers several key advantages: •It can be installed in live flow conditions, subject to operator safety •It is adaptable to host pipe conditions, including bends and offsets •It provides a hydraulically efficient joint free liner •It is installed through existing access points with low social impact The MWSL system could be designed in accordance with well-established tunnel theory and has undergone extensive testing and independent evaluation to confirm load carrying capacity under a variety of conditions. Projects employing the SPR system have been completed within the United States, Asia and Europe, including rectangular, elliptical, horseshoe and egg-shaped conduits. This presentation describes the MWSL system, testing and evaluation performed and projects undertaken – demonstrating the potential for application in solving similar deteriorated conduit problems faced in Asia.
