Project overview
Location West Coast
Date of completion 2023
Bridge 52, located across Goat Creek in Otira on the West Coast, underwent a comprehensive rail beam replacement project as part of KiwiRail's structural upgrade initiative, carried out by Liddell Construction. The project focused on enhancing the structural integrity and operational efficiency of the single-track steel bridge, spanning from April 2023 to its completion in December 2023.
Key scope components included the removal of lead-based paint, drilling of existing floor beams, installation of modern rail brackets, and modification of cross-bracings to accommodate new steel rail beams. Pre-cast concrete bolsters were fabricated on-site to replace existing supports, enabling the successful replacement of hardwood rail beams during a 7-day Block of Line disruption.
A highlight was the integration of safety-conscious innovations, such as a full deck under scaffolding platform, allowing 80% of the works to be completed outside the rail corridor. The involvement of our divisions, from mechanical workshops to heavy civil crews, ensured a collaborative approach despite adverse winter conditions.
The project was delivered on budget at $1.31M plus approved variations and received positive feedback from KiwiRail, achieving an 80% rating in client relationship management. The outcome effectively modernised an ageing structure, ensuring its functionality for years to come.
