Can SWA be run in the same metal trunking as singles?

[Mike Johnson]

Just give him in writing an estimate of how much it will cost to hide all the SWA to his satisfaction and copy it to the client, I think there would be some very embarrassed face's at the next project meeting.

Thinking further, 4M ceiling with the trunking at 3.7M which means working off MWEP or ladders, has the Health and Safety Co-ordinator been involved in this? their main function after all is the Safety of the workforce, easier to do if they do not have to leave the ground, is it possible to run the trunking around the walls?

We have a mobile tower which is plenty safe enough. It's been decided that we run 50mm tray below the trunking which is fine. Leave the bosses to sort out variations from scope

Just a vagary to throw into the pot when they are being awkward.

The most common accidents on site's are falls from height, if the work can be done at low level that is preferable than working off a tower that you have to access probably without a harness and up a ladder, unless it's a professional tower with internal access, kick boards at all levels and double rails, getting your tools and equipment to the top level also has to have consideration, not in a bucket pulled up on a rope, or worse carried up by you whilst climbing the ladder, who supplies the access equipment, if it's the site these things if relevant should be brought to the attention of the COW for them to sort out.

I would add that with 50mm trunking you need to be aware of bend radius of the SWA if the run is not straight. You might need to use a pair of 45 deg bends, etc, to get something sane. Also some suppliers have a very "square" 90 deg bend and others (like Unitrunk) have a bit more curve allowed.

We're fabricating ourselves due to lack of access to materials. I believe 4 core 10mm has a ten fold diameter for bend radius so definitely need to be careful we.dont fall foul of that

WTF???

If you have some cable tray you ought to be able to make a gradual 90-deg bend by cutting V-shaped sections out and bending it in the a fan-shape. You will need some short links to join up the inner edges that you cut away to give it some strength though.

We're abroad and it takes a couple of weeks and a lot of money to get anything here, materials were ordered by the office.

Ah, that makes some sense.

That's something that strikes me watching some of those North American series (Ice Road Truckers, Wikd Akaska, and the like. We're so used to just popping to the wholesalers to get common stuff from stock, or next day, or withing a few days if it's a special order. And planning on the basis that if we forget something, it's no big problem. Not just electrical, but for other stuff - e.g. I know I can pop round and pick up a bag of cement if I run out.
The idea that we have to accurately work out our materials a year in advance, have them delivered during a short window, and if we get it wrong then we're screwed is ... quite a mindset shift.

It's all to do with land area, if you look at any house in rural France, which is vast in comparison to the UK, you will see that nearly every house has a trailer sitting somewhere in the property, this is due to obviously to pick up supplies, but also due to the vast amount that companies charge for delivery.

Same applied here in NI and probably much of the UK.

Prior to online shopping ushering in the era of home delivery everything had to be collected. A builder's supplier may have delivered, but only if the order was sizeable and if you weren't near to them a not inconsiderable sum may have been involved.

Growing up I don't remember anything being delivered other than heating oil, with all other goods being collected by car or trailer. All seems a bit mad now considering the tiny scale of NI.

Wicks in the UK have deliver free for anything on orders over £100.00 in Kent, that is not a lot a large order now days.

Most places now offer delivery at reasonable cost, with modest minimum order for free delivery.

This only became available in recent years as a response to online options that had eaten into margins.

I know a guy who lives on a Welsh mountainside and doesn't drive. His life was revolutionised in a short space of time around 10 years ago. Previously everything involved planning, favours and effort, whereas now even his groceries arrive from 30 miles away with his only effort being to lug them the last couple of miles up a rough track. Not sure how he'd feel about carrying drums of armoured cable up there

He could roll them, scaffold tube or similar through the middle and rope slings on the ends, over the shoulders and pull.
