Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Does anyone have any input about productivity numbers for the New Austrian Tunneling Method (NATM)? Any help would be greatly appreciated!

Thanks.

These would depend on a number of factors such as type of rock, stratification, slope, size and depth of tunnel, water ingress, method of excavation etc.

NATM is a design and construction monitoring methodology not a production based estimating process.
