Ned Thomas, Yorke Peninsula Country Times

The future of one of Yorke Peninsula’s most recognisable waterfront landmarks is under renewed scrutiny after an engineering report presented to Yorke Peninsula Council two years ago classified the Port Vincent Wharf as structurally deficient.

The report, which is available to the public, also called for further investigations into the wharf’s long-term future.

Presented to council at its June 12, 2024 meeting, it documented widespread deterioration throughout the century-old wharf.

Port Vincent Progress Association president Greg Mills said parts of the wharf looked “abysmal” but that the structural integrity was believed to be “intact” for another year.

“The timber piles have had noticeable damage and the cross braces are similar,” he said.

The report recommended immediate restrictions on how the wharf should operate, along with three major investigations to better understand its remaining structural capacity and guide future investment.

The immediate measures were implemented by council in June 2024, soon after the report was released. Commercial shipping and fishing activities were ceased, and the wharf was restricted to pedestrian access, preventing vehicles such as forklifts from operating on the structure.

Mr Mills said the report’s three longer-term recommendations, advised for completion within three years from June 2024, remained outstanding, leaving about one year for investigations considered critical by the engineers.

“Bollards are up and there’s no boats allowed to tie up and there’s no vehicle traffic on the wharf, but we need to drive the long term in investigation to have a more intrusive look at the structure before June 2027,” he said.

“Tourism dollars are the lifeblood of this town.

“We cannot survive off the residents alone and if we don’t have the infrastructure to support it, they will go elsewhere.”

The findings have reignited community concern, with Member for Narungga Chantelle Thomas preparing to meet with concerned residents and the Port Vincent Progress Association after locals raised fears about the wharf’s future.

Warning signs under deck

Ms Thomas’s office confirmed the meeting is being organised, with a date yet to be finalised.

The report, written by specialist engineering consultants The Robert Bird Group, was commissioned by the Department of Infrastructure and Transport.

It documented deterioration across key structural components, including timber piles, crossheads, girders, braces and decking, with marine borer attack, timber decay and corrosion evident throughout the wharf.

The report found some timber piles had deteriorated from an original diameter of about 400 millimetres to as little as 165mm, while crossheads and girders had also lost significant structural capacity.

Although engineers determined the wharf could continue operating under strict loading limits, they recommended immediate operational changes to reduce stress on the structure, which were implemented by council.

The report identified three major actions to be undertaken within three years: intrusive investigations to determine the remaining capacity of structural elements; engaging a qualified engineer to design upgrades for sections of the wharf or the entire wharf; and investigating standalone berthing and mooring infrastructure independent of the existing structure.

The report states those investigations may require sections of the concrete deck to be temporarily removed to properly assess the condition of the underlying timber structure.

With a year remaining before engineers’ recommended timeframe expires, Port Vincent residents say the focus must now shift from identifying the problems to determining how one of Yorke Peninsula’s most treasured landmarks will be preserved for the future.

Responsibility clarified

Amid community debate over who is ultimately responsible for Port Vincent Wharf, the Department for Environment and Water has removed any uncertainty.

“The Port Vincent Wharf is on dedicated Crown Land which is under the care and control of Yorke Peninsula Council,” a DEW spokesperson said.

“As such, the council is responsible for its maintenance and safe operation.

“This land has been dedicated to Yorke Peninsula Council since 2005. DEW does not hold a lease or licence with the council over this land.”

The response confirms Yorke Peninsula Council has held responsibility for the wharf’s maintenance and safe operation for two decades.

A council spokesperson confirmed the council remained responsible for the Port Vincent Wharf.

“Council will continue working with the State Government on opportunities to maintain its jetties and wharfs as is occurring with the current works at Ardrossan and Edithburgh,” the spokesperson said.

Yorke Peninsula Country Times also asked council for an update on the wharf’s current condition, whether any recent engineering inspections or structural assessments had been undertaken, its responsibilities for the structure, future maintenance and renewal planning, funding opportunities, and the engineering report’s outstanding recommendations.

Engineering report: at a glance

Presented at the Yorke Peninsula Council meeting June 12, 2024.

Overall assessment: structurally deficient Engineers identified widespread deterioration across the wharf’s primary structural elements.

Key findings

• Timber piles reduced from 400mm to as little as 165mm in diameter
• Marine borer damage
• Timber decay
• Corrosion
• Deteriorated girders, crossheads and bracing
• Age-related deterioration throughout the structure

Immediate recommendations: implemented

Reduce stress on the structure by:

• Ending shipping and commercial fishing activities from the wharf.
• Restricting the structure to pedestrian access only, preventing vehicle loading.

Still to be completed:

Recommended within three years of June 2024:

• Intrusive investigations to determine the wharf’s true structural capacity.
• Engineering design for upgrades to sections of, or the entire, wharf.
• Investigation of independent berthing and mooring infrastructure.
