Clontarf Bridge, Cork

Project Overview

AQL were engaged to do a comprehensive restoration to Clontarf Bridge, Cork. Over time, the structure exhibited signs of weathering, structural wear, and required essential repairs to maintain its integrity and ensure it could stand up to the traffic and weather conditions.

client objectives

Ensure the longevity and structural integrity of the structure Apply protective coatings which will resist the adverse weather conditions the structure is exposed to. Ensure no pollution to the air or water during works. Aesthetically pleasing

Scope of works

AQL carried out a restoration and protection measures, including: Encapsulation and Scaffolding: A full scaffolding encapsulation was built to contain all the debris created, stopping pollution to the water and air. A scaffolding platform was constructed to allow for operatives to carry out the work in an efficient and safe manner. Surface Preparation: All of the steel was shot blasted to remove the existing coating, rust and any debris. Shot blasting was all done to SA 2.5 as per paint suppliers recommendation. Hydro-demolition was then used for surface prep on the underside of the bridge to prevent water contamination. Primer- A primer was applied as part of the paint system to allow for the best compatibility for the protective coating. Protective Coating- A C5 classified protective coating system was applied to protect the structure from erosion from salt water, waves, storms and adverse weather.

Challenges

Surface Contaminants & Deterioration: The presence of accumulated grime, biofilm, salt water and other sea contaminants on the steel surfaces necessitated thorough mechanical preparation before coatings and repairs could be applied. Contamination/ Pollutants: To prevent any contaminants or pollution to the water or air a full scaffolding encapsulation was designed and installed by AQL. Hydro-demolition was used on the underside of the bridge to stop any water contamination. Led monitoring in place to ensure air quality is unaffected in surrounding areas.

Results

Structural Longevity: The preparation and protective coatings significantly enhanced the lifespan of the steel, ensuring long-term durability. Weather and Erosion Resistance: The coating will protect the structure from the adverse weather conditions it will experience, along with protection from the river. Improved Aesthetic & Functional Integrity: The structure now appears revitalised, with a clean, task specific surface that enhances its structural performance.

Conclusion

The successful completion of this structural protection highlights AQL’s expertise in specialised steelworks and protective coatings on bridge and across other industries. Through meticulous planning, industry-leading materials, and specialist application techniques, AQL delivered a high-quality, long-lasting solution that ensures this bridge remains operational and protected for years to come.
