Permanent & Temporary Works Design for Tunnelling Projects
At HB Tunnelling, we combine our extensive on-site experience with engineering design to ensure that every solution is efficient, safe, and tailored to the specific requirements of each project. Our approach places a strong emphasis on constructability, value engineering, and sustainability, helping clients deliver projects more efficiently while reducing overall carbon impact.Â
All designs are developed in accordance with relevant UK design standards and regulatory requirements, including CDM 2015. Our process is structured to eliminate, reduce, and control risks during the design process, ensuring that health, safety, and buildability are considered from the earliest project stages.
