Port Penrhyn

Marine infrastructure works including jetty demolition & boat lift pier construction

Client : National Grid and Dickies Boat Yard

Location : North Wales

Contract Value : £400,000

Project complexities, simplified by Alpha:

  1. Working within a tidal dock environment, requiring careful planning around tidal movements to ensure safe and efficient delivery of works.
  2. Managing demolition while retaining existing structural elements, ensuring steel piles remained intact for potential reuse and future integration.
  3. Maintaining safe access and fall protection from the quayside, including installation of temporary fencing, handrails and floating access platforms.
  4. Operating within an active dock environment, requiring coordination with dock traffic and ongoing operations.
  5. Undertaking structural testing to inform future design, enabling the client to confidently progress with a new boatlift pier solution.

Scope of Works:

  • Demolition of an existing ramp and jetty structure, originally constructed to support the offloading of supergrid transformers for National Grid.
  • Retention of existing steel-encased piles, preserving structural elements for potential reuse and reducing environmental impact.
  • Installation of temporary access systems, including handrailing, fencing and a floating pontoon to enable safe working within the dock.
  • Management of marine working conditions, including tidal flows and active dockside operations.
  • Undertaking structural testing to determine load capacity, providing critical data to inform future development of the site.
  • Supporting the design and delivery of a new boat lift pier, including development of temporary works solutions for construction.
