The practice has undertaken specialist studies on a large number of challenging cavern projects in difficult or complex geological and hydrogeological regimes and this forms a major part of the group’s activities. The experience with large span openings in weak rocks is significant and has established the feasibility of schemes beyond prior precedent practice.
Solutions have been innovative, practical and technically straightforward through careful, staged sequencing of excavation and support / lining stages.
Geo-Design has carried out assignments that vary from specialist review to full detailed design and supervision of construction. The large portfolio of projects demonstrates world class capability in this field.
