Marine Wharf Rehabilitation Workshop
Monday, November 9, 1998
Battery Hotel and Suites, St. John's, Newfoundland

    Wharf rehabilitation involves more than just making repairs after accidents or repairing long-term deterioration.  Usually, a wharf structure will require rehabilitation because the intended use of the existing facility will be different than what had been anticipated in the original design, or operations may be resumed at unused or abandoned facilities.

    There are no specific codes or standards which deal exclusively with the rehabilitation of wharves.  Design guidance can come from several different sources, including various sections of applicable CSA Standards, ASTM Standards, PIANC Guidelines, textbooks, manufacturer's product catalogues, and many other sources.

    Participants in this workshop will learn valuable strategies and gain insight into the processes involved in the assessment, design, and rehabilitation of a wharf facility.

Workshop Content:

• using historical data sources, including original design criteria and as-built drawings,
• functional and dimensional requirements of proposed uses,
• loading, including live, environmental, equipment, vehicular, vessel, berthing, and mooring loads,
• inspection requirements for assessment of existing structures, including field investigation strategy and technique,
• structural analysis techniques for existing wharf structures,
• foundation analysis and load testing of piles,
• overview of typical deterioration and damage to wharf elements, including estimating useful life, restoring load bearing capacity, and extending the useful life of elements in a wharf structure,
• Case Studies:
• installation of a beam/pile system at Dalhousie Wharf to permit berthing of 80,000 tonne vessels at a facility originally designed to accommodate 10,000 tonne vessels.
• installation of a relieving platform at berth 31 in St. John's to upgrade permissible surcharge loads from 20 kPa to 50 kPa.

Ennio De Curtis, P. Eng., graduated with a B.A.Sc. in Civil Engineering from the University of Toronto in 1972.  Since then, the majority of his work has been in the field of structural and foundation design of harbour facilites.  He has been involved in the evaluation of existing facilities with regard to their structural capacity, remaining useful life and feasible repair options.  He has been working for the federal government for over 20 years, over which time he has overseen projects in every province east of Manitoba.  He is the Chairman of the technical committee for the development of CSA Standard S826 - Ferry Boarding Facilities as is an associate member of CSA Standards Steering Committee on Structures (Design).  He is also a member of the Professional Engineers of Ontario.  He is currently a senior engineer of marine structures in Ottawa.
