As a relatively mature industry, the world of machine tunneling is more conservative than it once was. While there is a place for standardized machinery and design elements on many projects, some projects require ingenuity and a progressive approach. Challenging and risky projects will always be a part of our industry and stepping out of the comfort zone of standardized technology on these tunnels is part of achieving success.

The effect of industry-wide conservatism is often the outcome of an effort to drive down risk, whether that is through contractual practices, industry regulations, or standardized technologies. However, all parties from contractor to equipment supplier to the project owner can be successful with challenging projects so long as the risks have been properly and fairly allocated.
