The design life of all new struchues is 50 years. The anticipated cost of the scope of work to be undertaken by the Contractor is $15,OOQ000. 7.1 Existing Timber Wharf Demolition The existing wharf was built in the late 1930's predominandy of timber piles and timber deck elements. The typical section includes timber piles, caps, stringers, and decking. A variery of sleeve type repairs are located on the timber piles. In addition, a portion of the timber deck has been replaced with precast concrete elements. The original fender system has been superseded by a new monopile type fender system which will remain in place. Wharf 2 will be demolished in its entirety as will a portion of Wharf 1. While the majority of the wharves aze timber, there is also a single concrete mooring dolphin located within the footprint of the existing wharf that will be demolished. There are several equipment systems located above and below the deck requiring demolition including a pneumatic hose mast system, mooring bits, and piping. As one of the key success criteria for the project is maintaining operations of the temunal, demolition must be phased to allow unintemipted access to the existing breasting dolphins and unloading equipment. 7.2 New WharF The new wharf will be approacimately 426 ft by 58.5 ft in plan and will contain two access ramps connecting back to shore. A new walkway system is required to connect the new wharf to the eacisting breasting dolphins to the North as well as the mooring dolphin to the South. While the Contractor may propose an alternative foundation, it is anticipated that the wharf will be supported by prestressed concrete piles and will contain a cast-in-place concrete deck. Mooring bitts and a new fender system will be installed along the face of the wharf. 73 Seawall A new seawall is required to protect upland areas from flooding as well as to protect against fuhue sea level rise as the existing berm does not provide adequate protection. The new seawall is expected to be constructed along the crest of the existing berm along much of the alignment and along the reaz of Wharf 1 to provide the necessary pmtection. The seawall will also serve as a retaining wall along portions of the alignment where upland fill is required to achieve elevations necessary for the Longshoreman's building and parking area. The existing slope pmtection will be augmented with the installation of new riprap along the face of the seawall. Page 8 d 26 °^:in��.
