The redevelopment of Berths 4 and 5

The redevelopment of Berths 4 and 5 followed a feasibility study undertaken by Marina Projects in 2012 that considered the operational requirements and options for development.

The preferred scheme taken forward for construction involved the removal of the existing linkspan bridge within St Helier Marina, to be replaced by a new pedestrian access bridge configuration improving access to Berths 4 and 5 from Albert Pier.

work undertaken by Marina Projects included a detailed consultation process that engaged with all key stakeholders and harbour users.

The new development involved the installation of improved visitor/waiting pontoons along the length of Berths 4 and 5 and a dedicated berthing configuration for both the inshore and offshore lifeboats and commercial operator, South Coast Cruises. The project also included improvements to the St Helier Marina wind and impoundment wall, as well as a reconfigured landside arrangement on Albert Pier involving the introduction of a secured access point to the pontoons and information signage.

The role of Marina Projects

The scope of work undertaken by Marina Projects included a detailed consultation process that engaged with all key stakeholders and harbour users. As part of the internal consultation and approvals process Marina Projects provided comprehensive business case analysis to support the application to the Ports of Jersey Executive Team and ultimately to secure Ministerial political approval.

Marina Projects has also led the consenting process; securing both Planning Permission and FEPA Licenses which, in due course, required the various conditions of the licenses to be discharged. Other work streams included project management, procurement and contract administration throughout the construction phase.

KEY CHALLENGES:

A number of key challenges had to be addressed for the successful delivery of the Jersey Harbour project:

■

Extreme Tidal Range

With a mean range for high water springs of 9.6 metres increasing to over 12 metres at Highest Astronomic Tide; environmental influences had a major impact throughout the project on design and layout as well as construction methodology and working arrangements.

■

Ground Conditions

A significant degree of value engineering was required due to the high cost associated with mobilising specialist equipment required for rock-socketing the large 24m long steel piles into the granite seabed.

■

Stakeholder Consultation

The existing berthing arrangements provide a berthing facility for a number of key stakeholders, including the RNLI. The development process required extensive consultation with the RNLI to ensure their operational needs were fully accommodated within the new scheme.

■

Programme

The works were undertaken during the winter months but with an absolute deadline for completion prior to the annual Jersey Boat Show in early May 2015.

To celebrate the successful completion of the refurbishment project, the very first vessel to take advantage of the new pontoons along Albert Pier was a 40-metre superyacht.
