Due to the purpose of the jetty, there are significant amount of movements on and off of the jetty and the is used extensively. The jetty requires maintenance of the steel piled foundations. 6 Berth 3 Basin (6B3) is a gravity retaining structure founded on a timber piled grillage that is constructed from red engineering bricks, concrete, Portland stone and granite. The front face of the ship production hall consists of a reinforced concrete deck supported on tubular steel piles. The scope of work is covered by four distinct work packages as detailed below; - WP1 - Survey of current level of corrosion of piles at 6B3 suspended Ship Hall jetty in order to inform design and build of adequate pile protection measures (if deemed to be required). - WP2 - Design of suitable solution for corrosion protection measures. - WP3 - Construction of said design. - WP4 - Protective wrapping to be applied to the top of circa 5 piles at another location at HMNB Portsmouth. Please note the location as North Corner Jetty West where confined space and tidal conditions will need to be present. The last full condition survey for the piles was conducted in 2019 and will be made available alongside drawings.
