Knysna Quays

Waterfront development
Planning, Feasibility, Design and Construction Supervision
PRDW were appointed by the Knysna Quays joint Venture as part of a multi-disciplinary project team responsible for the Integrated Environmental Management (IEM) of the project and project planning and design.
South Africa, Western Cape, Knysna
2008 - 2009

The scope included all marine aspects of the development from the conceptual design to detail design, tender documentation, adjudication, contract administration and supervision. The Knysna Quays Marina Development is a waterfront development comprising residential and retail components, as well as a small craft harbour. Approximately 100 residential units are provided with private moorings adjacent to the units. The small craft harbour provides for 108 walk-on floating moorings for the public and Knysna Yacht Club.

Alternative concept designs of the marina were developed interactively with the other disciplines of the professional team as part of a detailed IEM which involved the relevant authorities and other interested and affected parties to ensure an economically feasible and appropriate development in the extremely sensitive environment of a Lake National Park.

Detail design for tender and construction comprised the following:

  • 1.4km long steel sheetpile quay wall with concrete coping on the edge of the marina canals and small craft harbour.
  • Dredging of approximately 140,000m3.
  • Double deck bascule bridge (8m span) for pedestrians.
  • Walk-on floating moorings (108) with concrete anchor piles.
  • Boat ramps (3)
  • Boat launching dock.
  • Wave screen (200m long)

The contract administration and supervision of the marina contracts in co-operation with the professional project team was also performed.
