The Building Of Llyn Brianne Dam - Archival Construction Film

Archival footage from You Tube and put into one continuous 30 min video. This is the promotional film by Wimpey regarding their completion of Llyn Brianne Dam. Which is located near my home town of Llandovery, Wales. This is a fascinating look into its construction, opening and operation of this feat of civil engineering. A time capsule into the dam's construction and its community. I would love to hear from anyone who was involved in the development and construction of the dam.

Thanks for posting this. My late father worked for Wimpey on the construction of this dam. He drove dump trucks for them. He always spoke with fondness of this job even though they spent a lot of the time rained off! He loved the area and made some very good Welsh friends from his time there.

Thank you Mr.Harrison for explaining what a COPPER Dam was in answer to my query,many thanks indeed because I was very interested in this project.

[@paulnolan1352]

Wow, what an undertaking. We could pretty much just do jobs like this then without all the politics we get now. I went into the Plant game just a few years after this project as an apprentice Plant Mechanic and recognise many of the Machines at work for Wimpey’s. MVRH Rollers-Midland Vibrating Roller Hire!, haha, crickey, that takes me back!.

Thank you for uploading this,as I’m very fond of the area and have spent a lot of time at Llyn Brianne.

Nice place to go for a drive you can go right round it

Great old school Plant and construction, thanks for sharing 👍🏻

GREAT VID

Amazing what man can achieve whilst wearing turned down wellies and a donkey jacket, great video.

These Lads wouldn't do that kind of work today,

Don't see many people using a 1RB these days ( ie shovel) that's all operated for the first year on leaving school in the in the 1960
at 15 working on the M1 in Leicestershire.

1RB 😂, it's a long time since I heard that!

Strange how the distance covered by the dump trucks is measured in kilometers yet the water will flow in MPH

[@hiscifi2986]

Must pay it a visit one time, although I might have car-rallied over it many years ago.I wonder why it does not generate electricity..?

[@mathewmottram]

There is a small hydro generator there not shure when it was out there though

[@uncensored5104]

3 generators were fitted in the 90's

I wish they had shown the copper dam,being built because I ,m not sure what it is by the name.

[@brianmarshall1637]

I wonder what Wimpey,s price was,that,s of it is possible to price a job like that?

[@sallymarshall9548]

What year was this please

[@gregmorgan5332]

[@brianmarshall1637]

Please could anyone out there explain what a COPPER damis.

[@charlesharrison2248]

Coffer or copper dam is like a temporary dividing wall to keep the main waterway away from the working area ,it could be built with whatever is available at the time, stone rock clay or in later years steel interlocking piles driven int0 the ground,when the project is complete the dam is removed and the area allowed to re water.

[@paddythenotsopowerful2113]

1rb that’s it

No mention of welfare of the fish, unless I missed that bit?

[@guyshaw5533]

[@kirky4505]

i understand the water is very acidic due to the leaching of surface water from the surrounding forestry making it undesirable for sustaining fish stock, lime is added to the water on a regular basis to adjust the acidity

[@ivanivonovich9863]

2,000 mm = 200 cm = 2 meters! Why do they use the higher number? Perhaps just because it sounds bigger.

[@metricstormtrooper]

Because you don't have to mix measurement like you have to when using imperial measurements say 2584mm it would be 2 metres and 584 mm sort of like 8 feet 5 and 3/4 inches, complicated and more open to error.

[@558vulcanxh]

Why in metric ? What a fool this commentator is

[@Knappa22]

Why not? Metric has been taught in Welsh schools since the 1970s.

[@geraldlrstubbs]

Because that is how we measure everything in the UK

[@Knappa22]

@@geraldlrstubbs No. We measure things using both metric and imperial measurements. And the metric system has been taught in UK schools for nearly fifty years.

[@Zero_Ninety]

Because it's not the 19th century anymore.

[@jeffshultz5348]

Cause it’s a metric country.
