Abstract The Anzac Cliffs project involves two main elements: reshaping of the steep cliff, and realignment of the Manawatu River away from the cliff. The realignment of the river below Anzac Cliff was the last major development of the Lower Manawatu Scheme, City Reach Project….
Abstract The Health and Safety at Work Act (2015) requires companies to provide safe working environments for its staff. In response to this, our client sought to identify effective mitigation solutions for a rockfall hazard above an operational access road. The slope consists of a…
Abstract It is widely acknowledged that soil-structure interaction (SSI) has an important effect on foundation performance during earthquake loading. The standard way of handling this is to assume elastic behaviour of the soil beneath and around the foundation. For shallow foundation response there are three…
Abstract Counterfort drains provide a method of improving slope stability by controlling groundwater levels via subsurface drainage; they can provide significant improvement to stability at moderate cost. Published information on the design, initial effectiveness and, importantly, the long-term performance of such drainage is limited, particularly…
Abstract Bluff Road is a low use, single lane, coastal road linking two beach resorts on the north east coast of the Coromandel Peninsula. It is a popular pedestrian short cut between the two beaches, is the access way to attractive fishing marks and provides…
ABSTRACT The application of Unmanned Aerial Vehicles (UAVs) and photogrammetry for bulk earthwork calculations is a recent development for ground engineering in New Zealand. The approach developed on the Deans Head Land Remediation Project has proven to be an innovative solution increasing workflow efficiency to…
Abstract Following the 2010 to 2012 Canterbury Earthquake Sequence, a number a lifeline structures were noted to be at risk from damage from rockfall. An electrical transmission pylon, serving as a lifeline to a coastal suburban community of approximately 5000 residents, had been hit by…
Abstract The Auckland Volcanic Field, which last erupted ~600 years ago, is a late Quaternary monogenetic basaltic volcanic field of approximately 500 km2. A recent study (Leonard et al., 2017) has improved the accuracy of eruption dates for 23 of the eruptive centres. Previously only 12…
Abstract The two-lane bridge on State Highway 6 (SH6) at Kawarau Falls near Queenstown is scheduled to open in the second half of 2017. Designed to withstand a 1/ 2500 hazard level earthquake, the new bridge will provide better access into the Queenstown area and…
Abstract Landslides are common in sensitive, weathered pyroclastic soils in the Bay of Plenty (BOP). The clay mineralogy of these soils is dominated by halloysite, an inactive 1:1 clay mineral. Manipulation of cation content within the pore water of sensitive soils has been shown to…
