An architect’s, urban planner’s and visionary’s preference goes to making infrastructure underground and keep the ground available for other uses. And, as the time goes by, more & more underground structures are coming in vogue. Although, more expensive compared to elevated structures, underground structures help retaining the cityscape. One of the finest examples of underground structures is Paris Metro, wherein everything within the city has been made underground. Similarly, a 15 km long underground arterial expressway was constructed in Boston, with the idea to demolish the elevated arterial expressway. Several long and short vehicular underpasses have been constructed in various parts of India and other countries. A multistoried building, today, can’t be imagined without 2-3 levels below ground for parking.

Underground structures pose varied challenges to the planners, designers and constructors. An underground structure has to be located in a way to keep away from existing as well as future underground structures and utilities. Stabilising the substrata, dealing with varying rock conditions etc pose different levels of design challenges. Constructing diaphragm wall in rock requires expensive trench cutters.

Large diameter piles (3.0m dia and above) are becoming popular for speedy construction and better seismic resistance, especially in liquefiable sub-strata. Use of rock anchors, rock nailing, rock grouting etc are essential ingredients of an underground construction. Dewatering and waterproofing find a special importance in underground construction.

Design and construction of Tunnels using TBM and NATM technologies have their intricacies, which need to be addressed suitably. Selection of TBM for different types of sub-strata requires a very careful planning. For this reason, a more elaborate Geotechnical Investigation is a must. Construction of cross-passages find their own challenges of temporary/enabling works.
