How

In Sweden, tunnels and rock caverns are used for a wide range of purposes. Because the facilities are underground, and therefore largely out of sight for the general public, this aspect of urban planning is generally less well known to most people. Here we will highlight Swedish apsects of planning, geological conditions and tecnology used in underground construction.

Geological conditions for underground projects

There are many conditions to take into account before building a facility underground. Different legal aspects must be approved before a final building plan of an underground project is taken.

However, the given geological conditions of a site are facts which has to be considered and examined by experts, before the construction work begins.

Planning

We mostly live our lives on the surface, but beneath us is a resource that can be utilised in many different ways, and that can therefore be attractive to use.

Building facilities and transport links underground can offer alternative solutions that are interesting, practical and cost-effective.
Underground planning has several unique characteristics that the planner must be aware of. Key aspects are summarized here.

Technology & construction techniques

Underground construction projects involves a series of phases, from initial investigations to construction and operation. The most commonly used investigation methods, technology and techniques involved in the construction phase are described here.
