According to Ron Yarnell, PPG original equipment manufacturer (OEM) sales manager, the Green Manufacturing Award was established to recognize the NATM
member with the year's best solution or innovation that delivers a positive impact on the environment.
Based on the New Austrian Tunneling Method (NATM
), tunnel information construction cycles the processes of geological investigation, predesign, simulated construction, and optimization.

tunnel in stiff clay.
In the following sections, we propose a method to reduce the required number of integrated CAs and the overhead effort in data processing, focusing on excavation works in NATM
tunnelling in Singapore old alluvium - design assumptions and construction experience, in Tunnels and Underground Structures: Proceedings of the International Conference on Tunnels and Underground Structures, November 26-29, 2000, Singapore, 205-212.
Groves adds that mining methods, also known as NATM
(New Austrian Tunnelling Method), can be used in competent soils and rock that can be excavated by hand or mechanical breakers or backhoes, and which typically involve temporary shotcrete, steel arches or other elements and a separate permanent concrete lining.
The tunnel has been blasted through the rock using explosives, and using the New Austrian Tunneling Method (NATM
), which involves stabilization of the tunnel with rock bolts and spray concrete (shotcrete), before being lined with a waterproof membrane and permanent concrete inner shell, the company said.

The tunnel is being constructed with the most advanced technology, known as New Austrian Tunneling Method (NATM
), and would pass through the mountain range of Pir Panjal.
