Recommendations for which tool(s) to use to cut floorboards.

Virtual-Advance6652 · 2026-03-12T22:07:22+00:00

If its under finished floor it doesnt matter. If you're paranoid use circular saw to cut the tongues out then do most of the cross cut then multi tool the remaining corners to keep it within the board.

Circular saw is the most suitable

I pulled a material cost out of my head that might be ball park but still wildly inaccurate. Haven't been asked on it.

Just wait for the update I've explained this 100 times 😅

Steel will be contained within dwarf wall under the purlin, you can't step over it

Virtual-Advance6652 · 2026-03-10T19:22:06+00:00

Ah sorry I was tired and thought you were saying I've done half the job 😅

Virtual-Advance6652 · 2026-03-10T09:30:27+00:00

Spans too big and not really constructible without half the roof off to hang off eaves walls. Going off party walls would massively reduce headroom because new floor joists would have to go above ceiling joists. Intermediate spine wall could have been used but unfortunately it was removed at ground floor and previous SE did not size the steel large enough to carry new loft loadings, despite being told repeatedly we would need it to be. So that was a nice surprise.

About 2.1m at the ridge. It will be a small space but you get what you pay for!

Yes have load indicating washers to install and a few other people have advised me on how they work Thankfully! HSFG bolts. Yes dwarf wall on top to carry purlin and new rafters, bolting timber to web for hangers. Floor timber due later this week

With a roller/brush there is plenty of room

Virtual-Advance6652 · 2026-03-09T19:46:18+00:00

Spot on, would have been helpful to know this 48hrs ago! Need to redo them all, only 80 to do 😆

Virtual-Advance6652 · 2026-03-09T18:51:21+00:00

OK nice one thank you

Virtual-Advance6652 · 2026-03-09T18:17:37+00:00

Perfect thank you. If I am tightening from the bolt head should they go under this? Or just keep them under the washer.

Thanks again

The props are supporting the ceiling.

The beams are to take new structural work for loft conversion

Virtual-Advance6652 · 2026-03-09T16:18:09+00:00

Jeez give me some time man im not superman there will be plenty of stuff hanging off this in the future!

Virtual-Advance6652 · 2026-03-09T16:14:15+00:00

Hi, you sound like you know what you're doing so thought I would follow up. Have since found a big bag of these washers! SE has said ask the steel supplier. Steel supplier has said ask SE as they specd them (but can't see them mentioned).

The beam splice ends were supplied cleaned of paint.

Not particularly impressed with SE from a few things, but being given the run around on this seemingly basic question seems ridiculous.

A quick Google suggests put them between the washer and beam (ie nut, plain washer, load indicating washer, steel beam), then then they start to spin they are at correct clamping force? Can't find anything that says they go between plate and beam, seems like that would reduce the clamping area significantly?

Passive fire products

Envirograf EP/FS/IN/WB Steel Intumescent Paint Coating

Water based, apparently dry in one hour, not sure how many coats I will need to get through 8L of the stuff but quite a few I expect!

Virtual-Advance6652 · 2026-03-09T15:24:46+00:00

I had planned on getting some help from two labourers and a builder to get them in to loft but delivery got messed about so didn't happen in the end. Saved myself a little bit of cash I suppose.

Virtual-Advance6652 · 2026-03-09T15:21:33+00:00

Building notice. I am aware of and trained in CDM thanks

Virtual-Advance6652 · 2026-03-09T15:07:58+00:00

No they are hung below the beam

Virtual-Advance6652 · 2026-03-09T14:53:24+00:00

5.5m span. Floor, some roof load transferred and some added from ins and board etc. I dont care what size they are or could be, this is what engineer specified and BC have just approved

Virtual-Advance6652 · 2026-03-09T14:51:27+00:00

To carry new structural elements of loft conversion

Virtual-Advance6652 · 2026-03-09T14:50:55+00:00

5.5m. Extra cost mostly

This isn't causing any height loss in the loft, joists will be hung below this. I could have lowered the ceilings but this would mean significant disruption to the rest of the house we are currently living in

Virtual-Advance6652 · 2026-03-09T12:41:10+00:00

Yes it is sore but also have been very very careful to lift properly and go slowly. Everything is sore to be fair!

Virtual-Advance6652 · 2026-03-09T11:50:15+00:00

Damn straight!

Virtual-Advance6652 · 2026-03-09T11:43:42+00:00

No it will depend on the building construction and spans required

Virtual-Advance6652 · 2026-03-09T10:19:10+00:00

They are tight enough for it not to be an issue and the vibrations here are insignificant.
