"No methodology is constant, absolute and unchangeable." There may come a time when the current methodologies become inadequate. Engineering; it must be in the cycle of maintaining its existence in order to find new solutions, finding new solutions in order to maintain its existence. #Türkiye #Fermanoğlu #natm #tunnel #tunnelbau #engineering #construction #tunnels #tunneling #drilling

NATM Tunnel Construction Methodology

Exciting progress on the North East Link project! TBM Gillian joins the journey to enhance Melbourne's freeway network, driving towards a sustainable future The North East Link project in Melbourne has commenced the journey of its second Tunnel Boring Machine (TBM), named Gillian, following the progress of TBM Zelda. These TBMs will excavate twin tunnels, digging approximately 10 meters daily and reaching depths of up to 45 meters. The construction utilizes 100% renewable electricity, with locally produced concrete segments used for tunnel walls. In tandem with tunneling, five road headers are actively excavating the southern section of the tunnels using mined tunneling techniques. While minor vibrations may occur, they will be carefully monitored. Expected to open in 2028, this project aims to remove 15,000 trucks from local roads daily, significantly reducing travel times. video rights : North East Link For more details https://lnkd.in/gxJvJh9A #tunnelling #tunnel #renewableenergy #engineering #construction #civilengineering #civilconstruction #engenharia #engenhariacivil #engenheiro #engenheirocivil #ingeniero #ingenierocivil

Everything you need to know about tunnel construction safety!

Fantastic achievement - but took far to long. As with so many of the world's major infrastructure projects, reinforcement is a significant and large part of the work and not least the costs. It should be prioritised significantly higher than it is here on Fehmarnbelt. The right and sensible thing to do is to involve reinforcement specialists in the design phase so that it is made "buildable" both if it has to be done manually as here, but especially in projects where you want to automate the manufacture of reinforcement cages. ADDA 3D BIM specialists together with GMT Robotics can help with this. Consult us early on in your projects and you'll save money, build much more safely, with significantly fewer work-related accidents. Previous projects show that up to 10% of the total cost of large projects can be saved. So it's a no brainer. It also requires design intent to be in place early on, which makes planning the entire project much better and again saves money. Buildable reinforcement structures are the way forward.

Work construction of tunnels is indeed one of the most complicated and sensitive engineering tasks that involves great planning, accurate execution, and response regarding safety concerns. Whether carrying traffic, utilities, or even used as shelters, tunnels are important constituents of many infrastructure systems around the world. Building such passages underground is by no means free from troubles. Safety in the construction of tunnels is really a major concern, as the task is indeed hazardous-from possible structural collapses to even fire hazards. Thus, the adoption of advanced safety technologies and procedures for the protection of workers is very important in order to ensure the success of the project. This article explains the processes, the problems arising, the risks involved, and the modern tunnel construction safety technologies, taking as an example the recent modernization currently underway in Austria's Arlberg road tunnel.

Many parallels can be drawn for the challenges facing Australian High Speed Rail tunnelling below the National Parks in tunnel cross passages and ventilation reliief ducts to manage the piston effects of train operations.
