Project Overview
Moore Construction delivered the design and build of the Toms Creek Bridge for the Gibbston Valley Resort development, providing critical access to a high-end tourism destination in Queenstown.
The project required a fully integrated approach combining design, precast manufacturing, piling, and installation within a premium and environmentally sensitive setting.
Engineering Solution
The bridge structure consists of three pre-stressed Double T beams, forming a 12-metre span across Toms Creek.
Each beam measures 725mm deep by 2000mm wide and weighs in excess of 15 tonnes, with approximately 360 tonnes of pre-stressing applied to achieve the required strength for heavy vehicle loading.
The system is supported by cast in-situ abutments founded on 600mm diameter bored piles, providing a robust and durable foundation solution.
Precast Manufacturing
The bridge beams were manufactured off-site in collaboration with Hi-Stress Concrete, allowing for high quality control and efficient project delivery.
- Pre-stressed Double T beam fabrication
- Off-site production for improved quality and efficiency
- Prefabricated kerb boxing for rapid installation
- Use of temporary mould systems to streamline production
Construction Delivery
Bridge beams were installed using Moore Construction’s 80-tonne crawler crane, carefully coordinated to ensure safe lifting and precise placement onto the abutments.
- Heavy lifting of 15+ tonne precast beams
- Precision placement onto abutments
- Grouted shear keys forming a continuous deck
- Formation of a 6m wide bridge deck
Project Challenges
- Construction within a premium resort environment
- Coordination of precast and in-situ works
- Heavy lifting and precise placement of structural elements
- Maintaining programme efficiency within a constrained site
Outcome
The completed bridge provides a durable and high-capacity access solution for the Gibbston Valley Resort, capable of supporting heavy construction and operational traffic.
