Saving HMS Alliance Update - Piling Completed

Vibro piling work has just been completed, 4 days ahead of schedule. Work has now started on preparing the inside of the cofferdam for backfilling with a lightweight granular aggregate. Works over the next few weeks include trimming of the sheet piles to design finished level, insertion of a reinforcing capping beam and tie bars, as well as pouring of the aggregate infill.

Two raised sheet piles in the vicinity of the bow of Alliance have been left in order ensure that an equilibrium is maintained between the water pressure on the inside and the outside of the cofferdam. Once the tie bars are in place these remaining piles can be redriven into place.   

We have now raised £6.19m and now have £420,000 left to go.  Fundraising carries on in earnest.
