Presentation 1: KiwiRail Bridges – Temporary Works and Methodology
Vincent Wong and Melvin Auld - WSP
WSP recently delivered the permanent works design for two KiwiRail bridges: Bridge 188aMNL in Marlborough and Bridge 72MNL in North Canterbury. Bridge 188a trialled a rapid-install, short-span bridge system suited for replacement projects, while Bridge 72 involved replacing aging timber trestles on a live rail line without requiring a full block of line. The presentation by Melvin and Vincent will provide an overview of both projects, focusing on construction staging, the integration of temporary works into the permanent design, and lessons learned around efficient delivery under rail constraints.
Presentation 2: Highbank Power Station – Temporary Works and Methodology
Simon Therkleson- WSP
Highbank Power Station has been operating in Canterbury since 1945. Due to significant wear from high sediment loads, full replacement of the turbine and generator was deemed the most economical solution. WSP has led the structural design of the permanent works, involving the demolition and replacement of approximately 350m³ of concrete and associated works. Simon will outline the project scope, the phased approach to reconstruction, and how temporary works and sequencing decisions are influencing construction methodology and programme delivery.
Presentation 3: Homer Tunnel – Construction and Temporary Works
David Lyes-Presenting on behalf of Downer
Downer recently delivered an upgrade to the avalanche shelter at the eastern portal of the Homer Tunnel in Fiordland – a critical link on SH94 to Milford Sound. The project involved working in an extreme alpine environment with highly constrained access, requiring detailed planning and integration of temporary works into the overall construction methodology. David will present on behalf of Downer, outlining the challenges of construction in a remote, weather-sensitive location, the staging approach adopted to maintain road access, and how temporary works were integrated into safe and efficient delivery of the shelter upgrade.
Refreshments will be provided courtesy of the event sponsor, Altrad RMD New Zealand. Get in fast as places are limited, this is one not to be missed.
The Temporary Works Forum NZ (TWFNZ) is pleased to announce their August public meeting and seminar event. The event will be a chance to catch up with peers, network, and listen to a series of presentations showcasing recent project experience and temporary works challenges across the country.
