    Another diving facilty 'on the drawing board'

    Yet another proposal for a major diving facility.

    It would be very convenient for us if it goes ahead. Not holding my breath though!

    What do you do in these facilities, nail skills a bit deeper down or something?, surely diving a deep swimming pool is still as shit as diving a local swimming pool.

    A 500kW fan running for the entertainment of one person, dumping waste heat into a massive tank of water. I'm struggling to see the 'tremendous environmental benefits' TBH.

    Is that blue abyss thingy still on the drawing board?


    I can see the "deep pool speciality" on the cards (pun intended).

    I'm still curious about how they do a 30m+ excavation without destabilising the surrounding ground. It cost the British Museum a metric shit ton of money to do.

    If they are running the fan for simulated parachute free fall training,
    they have to pay for the cooling of the fan, so why not take advantage
    and use the waste heat.

    Nothing we do is environmentally​ friendly, diving simulation or free falling.

    Because the amount of entrained carbon in all the concrete required for the groundworks alone (not to mention the steel frame) will wipe out any environmental benefit?

    And unless my calcs are out that's 4 megawatts to raise 4000m3 of water one degree. So unless that is a hell of a fan then there's going to be a tad more heating required.

    It's all about deflection and settlement. Digging deep holes in a field is no bother at all if you don't care about the surroundings. Secant pile a shaft with continuous flight augers (big drill bit) or even open bores and let it settle. Just look at the coal board in north yorks / Derbyshire. They dug wherever they wanted. There is a section on the m1 between trowell and j26 that has sunk so far into coal workings below the tarmac is 2.5m thick. They just keep planing a bit off and topping it up.

    London is a different game. If you could look under great george st adjacent to parliament, where they dug the jubilee line, you'll see more compensation grout than soil. There are lots of micro-tunnels for grout under Big Ben and the ICE building. That's nothing compared to the number they put under the building next door. Hundreds of tonnes of grout pumped in to put the building back exactly where it started. What building could be so important?

    ....Royal Institiion of Chartered Surveyors (RICS)

    QS's are worse than lawyers when they're not paying the bill.

    They do this at the ski slope in Tamworth. Rejected heat from chillers heats a pool next door.

    At Chill Factor Manchester, they just dump the heat out into the M60. It's quite well insulated - 5 inches of very high performance PIR foam, and it's so air tight it was impossible to measure the leakage. In the summer it takes 800kW just to keep the inside at -6deg. That's 3 grand a day in electric.
