Portals

Adits are small tunnels for access into the undergroundout you.

Adits.

Shafts

Shafts are inclined or vertical excavations often circular in shape built to access deep locations underground

Tunnels.

Tunnels are sub-horizontal excavations of sizes generally ranging from 2.5 m to 15 m

Caverns

Caverns are built for underground storage or for the installation of equipment

Portals are the starting location and opening for a tunnel

Dean has an undergraduate degree in Geological Engineering from the University of British Columbia in Vancouver, Canada (1985) and a Masters Degree in Engineering Rock Mechanics with Distinction from Imperial College, University of London, England (1990). Dean is a registered Professional Engineer with the Engineers and Geoscientists of British Columbia, and the Association of Professional Engineers of the Yukon.

 

Dean started his career in the underground deep-level gold mining industry in South Africa learning and dealing with highly stressed ground and the daily occurrences of rockbursting. Dean also lived and worked for extended periods in Hong Kong and Switzerland involved with the design and construction of a variety of large and deep underground excavations associated with major transportation projects.

 

Dean was involved on such world famous underground projects including the Lesotho Highlands Water Project, the Hong Kong Airport Core Projects, and the Gotthard Base Rail Tunnel.

 

Dean regularly attends and presents at industry conferences including the International Tunneling Association (ITA) World Tunnel Congress, Rapid Excavation and Tunneling Conference (RETC), North American Tunneling (NAT), Tunneling Association of Canada (TAC), and the British Tunneling Society (BTS).
