Government of Canada Posting: Saint Andrews Harbour Market Wharf Approach Trestle Replacement and Infill Project – Open Science and Data Platform

CBCL was engaged by the Town to provide engineering services, including detailed design and tendering services, in support of proposed rehabilitation and expansion works at the Market Wharf. The wharf requires rehabilitation to extend its operational lifespan, and the Town would like to expand the footprint of the usable wharf area on shore. The Town have determined that their preferred option for rehabilitation and expansion of the wharf (the Project) is the Hybrid Infill and Partial Pile Wharf design option, which involves the installation of a 4,545 sq. m rubble mound berm and steel pile supported concrete deck structure along the existing shoreline to increase the useable wharf area on shore. The new 41 m long x 7.62 m wide Approach Trestle consists of steel pipe piles supporting a reinforced concrete super structure which will extend from the new shore infill and transition to the existing Intermediate Trestle. The new wharf section will require the installation of approximately 30 new steel piles to support the Approach Trestle. An armour stone revetment will also be installed around the new infilled areas and along the existing seawall at the Project site. This protection will be constructed with a 1:1.5 Vertical / Horizontal slope and will consist of a rock fill core protected by a layer of sub-armour drain stone (700 mm thick of 50 – 150 kg stone) and an outer layer of armour stone (1400 mm thick of 500 – 1500 kg stone). Construction of the new infrastructure will require infilling below the ordinary high water mark (OHWM). Based on the selected design, there are three general footprint areas below the OHWM that require infilling, including a total area of approximately 1,460 sq. m on the northwest side of the existing wharf, 2,440 on the southeast side of the existing wharf, and 645 sq. m in the area of the existing Approach Trestle during construction of the proposed works. A temporary infill area adjacent to the Approach Trestle may also be …
