Brown, I.R.; Perrin, N.D. 1977 Wellington Hospital redevelopment: combined service and traffic tunnel site investigation. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EG 266 26 p.
Abstract: Two cored drill holes were completed along the proposed alignment for a services tunnel at Wellington Hospital. The engineering geological features that will affect tunneling are discussed. Construction of the tunnel is likely to cause settlement of the existing Seddon Wing, and data from The Terrace Tunnel are presented to help in settlement prediction. (auth)
