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.
