West Jetty and East Pier Connection

Client: Shannon Foynes Port Company

Overview

Niaron undertook the construction of an open-piled jetty structure, featuring precast concrete beams and in-situ reinforced concrete deck. The project was strategically located in the central area of Foynes Port, positioned between the operational East and West jetties. The implementation of Niaron's "dry construction" methodology ensured that port operations continued without disruption throughout the construction process.
 
Archaeology & Environment

Niaron enlisted the services of an archaeologist to conduct ongoing monitoring of the work area, ensuring that the construction activities did not negatively affect any sub-surface archaeological deposits, materials, or structures.


To safeguard marine mammals during piling operations, a Marine Mammal Observer was on-site. The implementation of a soft start procedure, gradually ramping up equipment to full power, was adopted to minimise any potential impact on the area.

Demolitions

To enable the integration of the new structure, sections of both the East Jetty and West Quay were demolished. Existing reinforced concrete fenders, each weighing more than 60 tons , were taken down and transported off-site for disposal.

Additionally, the footprint of the new jetty structure was cleared by removing an existing piled access pontoon and gangway.

Piling 
The piling phase involved the installation of large diameter steel tubular piles including static and dynamic testing. An incremental piling approach was adopted during construction synchronised with the deck construction process, this method eliminated the requirement for water-based construction equipment and provided unimpeded marine traffic flow during the project
