Update on the St Marys Quay Extension Works: From Kier Construction

Pre-casting works on the Quay Extension concrete blocks is continuing in Plymouth.

Dredging work continues and they have now reached the bed rock and this is being broken out with a rock wheel. This is proving to be a slow process, and in order to maximise weather windows and minimise any delay, Kier are mobilising additional resources and plant in order to work 24hrs, subject to necessary approvals. They say that they will seek to keep any disturbance to a minimum.

Dredged material will be delivered to Porthloo beach via landing craft and also using a flattop barge. The vessel will be beached on Porthmellon and then offloaded into forward tipping dumpers and transported to Porthloo by road. Both beaches need to be used, as there are tidal restrictions to the times that Porthloo can be accessed.

Following the dredging, a guide frame will be installed on the sea bed and concreted in place. Concrete will be batched at Parting Carn Farm. That’s the old Lagan’s site. The concrete will be delivered to the end of the quay using 5m3 concrete mixers.

The jack-up barge is due into St Mary’s harbour early next week and will sit inside the commercial berth close to the old quay. The crane barge will follow within days, after which the crane can be transferred onto the barge and the flattop towed to Plymouth.

The jack up will be assisted at all times by the MTS Vulcan 2 tug. She will be left within the inner harbour along the old quay until the dredging operation has been completed . When that work is done, she will be towed into position on the outside of the commercial berth, parallel to the new extension. That means the vessel won’t block the berthing of the Gry and the Scillonian when her season recommences.

Harbourside building refurbishment works:

The old ticket office has now been removed. The construction of the new ticket office will commence towards the end of the month. This has required structural re-design to ensure compliance with current construction regulations. As soon as this is complete and approved by the Mace Project Manager, construction can begin. Provision will be made for a temporary ticket office prior to the Scillonian recommencing her schedule in mid-March.

Kier intend to construct the foundations for the new covered walkway by the end of March and to follow with the walkway in April.

    I do hope that surveys have been undertaken to establish the effect of the extension of the
    quay will have,( if any) on Porthloo,Porthmellon and Town beaches, it would be a great pity if they lost all their sand etc. due to a change in tidal flows.

      I wouldn’t worry, the Harbour will silt up even quicker now as the Quay extension cuts down the anti clockwise tidal flow in the harbour. Porthlow may lose sand but the rest won’t.
      If the money was spent on a new “smaller ship” than bigger quays, etc we would be going the right way. What is going use the new enlarged Quay?

      The only people gaining are the Duchy, charging for… renting out fields, providing safety boat cover, Piloting, harbour dues for barges, landing craft etc..and having their propertly done up for free with pubic money? And they aren’t a commercial concern?. ..as for giving up harbour ownership but retaining freehold?

    Jann, I’m not complaining about the improvements to the quay. It’s the twenty first century and modern visitors expect certain standards of travel when going on holiday. Rose tinted spectacles are simply no use when we are in fierce competition with other (cheaper) destinations to attract much-needed visitors .The islands cannot stay stuck in the perceived bliss of the past. That is the blunt truth.

    Unfortunately, many of these projects seem to be badly designed, badly organised and seem to suffer delays that might have been foreseen (like the contamination problem between the sea wall and Rat Island). Sadly it’s Scillonians and visitors who have to live around the chaos and delays that these ‘oversights’ cause.

    With finite and precious resources, money needs to be spent wisely not squandered on hard uncomfortable seating at the airport where it seems each one of those new blue seats costs over £600!

    Then there will still be the huge problem of the antiquated system at Penzance quay where passengers often have to wait in the open in filthy weather, see their luggage roughly dumped into puddles on the quay so they can struggle through the crush to claim them, and THEN it really feels like the Dark Ages! Not good 🙁

      You say about the passenger facilities at PZ, what about the freight storage? Not only is there the normal extra cost but almost every online store won’t post to Isles of Scilly or make a huge extra surcharge for packaging & delivery to the quay or simply refuse after their first experience . This makes a nonsense of the broadband improvements and make them little more than status symbols. The volume of freight in is enormous now and no improvements planned, by contrast visitor numbers have dwindled yet extra capacity is being created.

    “…there are tidal restrictions to the times that Porthloo can be accessed.”
    Even WITH the huge and very expensive new slipway!
    Porthlow looks like an ugly industrial estate now 🙁

      The Islands have been an “ugly” building site for five+ years now, its just spreading out.
      The Islands have lost the charm and draw they had….. for ever!
      I hope all you people driving all this pointless development will be happy when you leave to go and spoil somewhere else !!

    Porthloo and Porth Mellon are such favourites. what is going to happen to all the stuff you dump there? will it be taken away and the beaches restored? If yes how long will that take?
