    Also of note is that the "disappearing machinery" story isn't entirely made up. Nenagh Guardian has a photo of the top of an old digger poking up from the bog just metres from the site of the motorway construction!

    "Non technical observers"......................Is that us?

    See the picture of the guy standing next to the damaged road surface. He is not wearing a Hi Viz or a hard hat and therefore may not be construction staff so should not be there. Just thought I would point that out.

    The last picture looks like a picture scalped from this thread also. Tech2's picture possibly.

    Check out page 17 of the online addition of the nenagh guardian this week, part of the new road not near the bottomless bog has fallen away. Picture of same on front cover.This does not look good.

    Nice photos lads.

    Am I right in saying that the Bog of doom and the newly crumbled section which is a mile to the north of it are neverthless BOTH south of the Birdhill interchange meaning the Birdhill - Nenagh segment can open soon as planned.

    Just to confirm the difference.

    1. Annaholty Bog = The Mire of Gloom ( newly crumbled )
    2. Drominboy Bog = The Bog of Doom

    Excerpt from article two years back,
    Construction News (00106860), November 8, 2007

    The article focuses on the N7 route scheme in Ireland. The project, which is part of the link between Dublin and Limerick, involves developing a new 28 km motorway standard cross-section on a greenfield site, with various interchanges, underbridges and link roads. It traverses two bogs, at Annaholty and Drominboy, and connects to a 10-kilometer section of the Nenagh Bypass. Irish foundation specialist :D "Lowry Piling" :D is delivering the piling contract for client Limerick County Council.
    Excerpt from Article:

    Fully instrumented rigs have been used to install piles over two bogs as part of a major road scheme in Ireland.

    The N7 route scheme, which is part of the link between Dublin and Limerick, involves developing a new 28 km motorway standard cross-section on a greenfield site, with various interchanges, underbridges and link roads. It traverses two bogs, at Annaholty and Drominboy, and connects to a 10 km section of the Nenagh Bypass, which is being widened to high quality dual carriageway.

    Irish foundation specialist FK Lowry Piling is delivering the piling contract for client Limerick County Council. The main contractor is Bothar Hibernian N7, a joint venture between Coffey Construction, McNamara and Portuguese firm Motaengil. Engineer for the works is RPS and the project manager is Hyder Consulting.

    The €1.5 million scheme is the Largest piling project in Ireland for many years. At Annaholty bog alone, 4,050 270 mm square precast reinforced concrete segmental piles are being installed to form the foundation's for the road and earth embankment.

    Annaholty is a peat bog up to 12 m deep, below which lies sand. The piles are being driven to an average depth of 30 m, with pile loads of between 49 and 80 tonnes and pile spacings of 2.5 m on a herringbone grid pattern.…

    Interestingly FK Lowry Piling do not feel that the Mire of Gloom and the Bog of Doom projects worthy of inclusion on their website especially where one would expect it here .

    Great pictures tech2!

    It's good to see that they're not skimping on the armco at the verges, it's like the M6 Galway-Ballinasloe in that sense. In contrast, the M6 from Athlone to Ballinsloe has a lot less armco in the verges, even in places where you would usually expect it to be.

    There are people walking the road daily now from the locality when the works have finished up in the evening.

    The Mire of Gloom in Annaholty has an interesting history, it tends to get bored....and then it moves.

    http://www.limerickleader.ie/north-east/Pat-happy-to-repeat-tales.5263970.jp
    The Annaholty/Gouig bog moved twice in recent history, first in 1880 and again in 1924.

    "A local man taking his milk one morning to Birdhill Creamery was amazed to see stacks of turf shaking on the bog. Then he saw the great bog moving forward in a floating onward movement".

    The area around the County bounds is still known as "The Moving Bog" he said.

    Thats intresting sponge bob. Great pics tech2. That hole is going to be some setback. I can see all the other projects been completed before this is sorted out. There is a bog something similar around killarney nearer gneevguilla i think that moved like the one in birdhill. Apparently several people were swept away. Some one else might know more about that.

    That chunk of road that fell off the side of the motorway is an indication that this stretch through the bog may fall apart in a few years time. Every decision on the scheme has been poor/wrong. From the route selection to the contractor. And ....... .................. it's behind schedule. :(

    Big PDF on the geotechnical aspects of the bog here it was posted earlier in this thread IIRC and shows photos of the Mire of Gloom in Annaholty including bog movements and the works themselves.

    http://www.geolsoc.org.uk/webdav/site/GSL/shared/pdfs/specialist%20and%20regional%20groups/TVGS_IGS_presentation_Jan2008.pdf

    and further info on bogslides and the like here.

    http://www.agec.ie/common/3%20March%202009%20-%20AGEC%20Presentation.pdf

    The geotechnical people, Hyder Consulting, were due to finish up in late 2008 but somehow I suspect that they will spend most of 2010 tied up with the Bog of Doom and the Mire of Gloom. West of Ireland bogs are pusscats compard to midland bogs , 5m deep not 12m and lying on rock not sand or glacial till.

    I would be rather nervous about any M4 project gettin the go ahead between Longford and Mullingar that goes anywhere near a bog.

    I bet you wouldnt believe it that I took all of them with a mobile phone. I had to do some serious editing to bring down the light on most of them. Soon I shall have my proper camera back to take better quality photos of the finished article. Generally I'd say it's not too far off completion from Birdhill to Nenagh some minor lining to do and work on the verges. I was going to drive from Birdhill to Nenagh but the on and off ramps were blocked with construction workers at the bridhill interchange.

    Anybody who wanders the Mire of Gloom in Annaholty is kindly requested to photograph any bog movement they see .. fractured lines with turf visible ....near the road.

    Next we go to Jacek Kuras. Jacek is a shuttering carpenter who BLOGS God bless him. He was shuttering out in the Mire of Gloom only last year and has a fabulous photo collection and some great commentary in his blog.

    http://jackfirejobs.blog.onet.pl/
    In April of 2009,I and 3 of my friends started serious job on famous Annaholty Bogs,about 15km from Limerick at new motorway N7 site in progress with COFFEY CONSTRUCTION Ltd.

    There is no evidence in the Nenagh Guardian photos that any of Jaceks shuttered pours failed. It looks like maybe a pile or two sheared for some reason but that they were uncapped by one of Jaceks concrete moguls.

    As Jacek Explains
    Concrete piles made of steel & concrete seen above was piled into peat-bog average 30 up to 45 meters deep until solid rock under bog.

    If over 45 m of deepness wasn't solid rock underneath,so was made big concrete beam covering sometimes dozens of piles

    Basically Jacek built concrete structures over piles that DID NOT HIT BASE ROCK BELOW THE BOG at 30m or 45m or less depending on the pile length.

    Which seems to be rather a LOT of them. :eek:

    Thats true i looked at the two websites that spongebob left, it shows the moving bog in kerry years ago. Theirs no reason why this new road through the bog may disappear some time with catastrophic results. The locals did say it was bottomless.....

    This could be the world's first moving motorway. Think of the fuel savings.

    Let me put this in perspective. The M7 has piles driven to a depth of up to 45m in places...although Mysterious says 36m precisely FWIW.

    The tallest structure ever built has 50m piles underneath. although they are bored piles with a diameter of 1.5m each not driven ones.

    Canary Wharf Tower has 20m-25m piles starting about 4m below the level of the water in the dock outside ( see page 340 and previous ) , again bored.

    Well Caraway I didn't leave out the bit about the deepest raised bog in Ireland being 15m deep or did I :p

    So :eek: WTF :eek: is under those things that 20m of extra piling won't sort ???

    Spongebob why do you always constantly have to make a jibe or make some twists to all my posts and replies. Stop it.

    My uncle worked at this site.. I'd listented to him far quicker than you about this.

    I said "around 36 metres" and the majority of the dept is 36 to 40 metres.
