Gibson Bridge
The project involves replacing the existing bridge with a new precast concrete structure and upgrading safety infrastructure, including fencing, railings, and barricades. The aqueduct, a fully operational bluestone-lined open channel, requires careful planning to ensure uninterrupted functionality and structural preservation during construction.
Project Highlights
-
Project completion was ahead of schedule
-
We were able to maintain the functionality of the aqueduct throughout the construction of the project whilst also continuing accessibility for landowners who rely on the bridge
-
Our client, was highly satisfied with the work completed, meeting their expectations and project requirements.
Services Provided
-
Conduction of a detailed investigation of the existing bridge and assisted with engineering design for the new structure.
-
Design of bridge, using precast segments for faster construction.
-
Installation of a temporary pedestrian bridge to maintain safe access during construction.
-
Procured and fabricated steel members, then hot-dip galvanized them for durability.
-
Coordination of the assembly and installation of the bridge to meet engineering tolerances.
Services Provided
-
Assessment of the condition of the deteriorated carpark and surrounding areas.
-
Collaboration with our client to develop a Request for Quotation (RFQ) for the rectification works, providing expert advice and recommendations on the best approach to address the issues within budget and time constraints.
-
Implementation of safety measures by cordoning off the affected areas to prevent public access during the works.
-
Carrying out the necessary resurfacing and repairs to the carpark and other high-traffic areas, ensuring a safe and functional environment for the public until the larger capital project is completed.
Challenges
-
A tight two week construction window, requiring efficient planning and execution.
-
Close monitoring of subcontractor work and alignment with design specifications.
-
Ensuring minimal disruption, including providing temporary pedestrian access during construction.
-
Maintaining access for landowners to property.
-
Strong and concise stakeholder management.
Outcome
The Gibson Bridge project was successfully completed within the tight two-week timeline, with the new 40-tonne rated bridge installed safely and to the required specifications. Temporary pedestrian access was provided during construction, and all stakeholders were pleased with the outcome, including the improved safety measures. The client commended the team for their exceptional communication, site safety, and successful project delivery.
