Weekly update – 30 April 2021

It’s been a massive week for our marine site team with the completion of the first 100m of rock revetment on the eastern side of Spur Redoubt at Frontage 1 (Long Curtain Moat). This is a huge milestone in constructing the new sea defences in this area.

Building the revetment involved the placement and accurate packing of the rock in two layers, ensuring there were sufficient voids to dissipate the force of the waves. The marine team will demobilise from site now until completion of the west waling beams (beams that anchor the steel sheet piles in place), returning in the summer to continue the rock revetment on the west.

Our thanks go to the Queen’s Harbour Master Portsmouth and the team at Portsmouth International Port and their pilots for helping to provide anchorage and for the safe transhipment of the rock from the coaster to the beach.

All 18 of our concrete tide pools have been installed in the rock revetment. These pools are designed to create ecosystems that mimic natural rock pools found on rocky coastlines, and will increase biodiversity and create additional habitat for marine species. What a wonderful ecological enhancement to the coastline.

The weather remained fair, and so did our progress with piling. We’re not far off completing the section of work to the west around the Spur Redoubt. This will mean completion of all piling works at Frontage 1 which will be a cause for celebration for both the team and nearby residents.

Great progress all round – so much so that we’ve all decided to take Monday off. Happy Bank Holiday Monday everyone!
