Junior Club House and Wave Protection

Structural Design

Design Engineering (as Wilkie) was approached by a committee member of the Fremantle Sailing Club to design a new junior club house including wave protection to provide a calm area for junior club members to rig their boats and set sail. Design carried out this work on a pro bono basis.

Design provided structural design, detailed drawings and architectural drawings for the clubhouse, and designed the wave protection breakwater groyne to protect the building against heavy seas. To build the groyne several thousand m³ of clean sand fill was laid and covered with geo fabric to protect the shoreline immediately adjacent to the clubhouse. Approximately 200 m³ of limestone rocks imported from a local quarry were then benched against the geo fabric and laid out into the ocean to create a wave protection groyne approximately 30 m long. 2T blocks minimum were required to resist the calculated dynamic wave actions.

The clubhouse was built from limestone blocks, suitably matched to the existing heritage buildings of the Fremantle port area. To provide additional protection against chlorides and wind, Design ensured rigorous galvanising and painting specifications were applied to all exposed materials.

A builder who was associated with the club carried out the building and construction work with site engineering, inspection and review by Design when necessary. It was a most satisfying project to be associated with.

Project Brief

Outcome

  • Fremantle Sailing Club got a first-class junior clubhouse at minimum cost
  • A safe and calm area for junior sailors

Background

Design was approached by the Fremantle Sailing Club to design a new junior clubhouse including wave protection. As the club had only a small budget, Design agreed to carry out this work on a pro bono basis.

Project Objectives

The key objective was to create a new club house for junior sailors and to provide a calm area for them to prepare their boats and set sail.

Challenges

The biggest challenge was to complete the engineering and design component efficiently and to utilize materials, methods of construction and local contractors to ensure the project met the budgetary requirements of the sailing club.

Our Approach

Design provided structural design, detailed drawings and architectural drawings for the clubhouse, and designed the wave protection breakwater groyne to protect the building against heavy seas. To build the groyne several thousand m³ of clean sand fill was laid and covered with geo fabric to protect the shoreline immediately adjacent to the clubhouse. Approximately 200 m³ of limestone rocks imported from a local quarry were then benched against the geo fabric and laid out into the ocean to create a wave protection groyne approximately 30 m long. 2T blocks minimum were required to resist the calculated dynamic wave actions.
