Tunnel Construction

Tunnel construction projects present a very specific set of challenges, namely working in a very confined space with the risk of collapse.

The map shown below identifies by country all large scale tunnel construction that has taken place since 1900.  It is apparent that activity has been very high in China, most of which has been during the past twenty years.

The animated feature below shows the development of large scale tunneling projects on the Eurasian half of the globe since 1900.

The map below shows in greater detail the breakdown of existing completed large scale tunnel projects in China.

The map below identifies where large scale tunneling projects are currently taking place around the world. Large scale refers to a tunnel greater than 13,000m in length.

Tunnel construction companies and project management companies need to be completely familiar with the national standards associated with tunnel construction as well as international best practice. It is therefore imperative that the relevant standards and codes of practice are very well translated without any ambiguity lingering. Even minor translating errors can have significant consequences. It is not unknown for a well intentioned translation to translate the opposite to what was originally meant. Therefore, following the structured process laid out by BS 15038 is highly advisable and will add an insignificant cost compared to the entire project cost and could easily help avoid a sinificant issue.

The table below highlights some of the British Standards associated with the construction of tunnels.

In the USA tunneling on land for roadways is governed by AASHTO (American Association of State Highway and Transportation Officials) guidelines. National standards exist in different countries.
