To answer Stuving (as a non-architect but who sees lots of plans at work) the drawings are produced so that if they are printing without reduction on a specified standard paper size they will be to scale. The scale (and usually the page size at which they should be printed) normally appears in the title block, conventionally in the bottom left of the drawing.

These days drawings are often produced as part of a system known as BIM, an integrated IT system for capturing all the information about a project which those who I believe now much more than I do is revolutionising the construction process, at least at the scale of single buildings.

March 25 2020 will mark 11 full years of posts under this heading, competing closely with the Tavistock extension for procrastination.

The equivalent thread on the Hob Nob Reading FC fan forum has been going for even longer:

The first post there (dated 05/05/2007) says:

I've seen BIM used (although I thought it was BIMS) whilst at ATKINS and it seems to be a very good system, but needs a very good plotter/printer to work properly.

Exactly. Just the point I was making. The drawing I was looking at had a box at the bottom right corner saying "A1 scale  1:500", so if I had an A1 print from its originating system, correctly formatted for the printer, I could take dimensions off it. If I had it on screen on its originating CAD/CAE system the software could do that for me. But with a print on some other size of paper, which in turn is viewed on a PC screen, I'd need to find the A1 sheet corner marks, measure them and some other dimensions off the screen, and do some sums to get anywhere. And those corner marks are not always printed - note that the drawing scale is in terms of the full sheet size, not the drawing frame.

Scaling of a drawing!
In my career there has always been a specific instruction not to scale dimensions from the drawing as that leads to error.

In your career, yes. But otherwise? I wasn't thinking of going down to the site and doing a bit of freelance building. I just wanted to read the drawing as a drawing rether than look at it as a sketch and say "I wonder how wide that platform is going to be - if I had a drawing it would tell me, accurately enough".

BIM = Building Information Modeling. I guess S could = System? :-) I've always known it as BIM.

Best use I saw was combined with A/R = when the device was waved around infront of the wall, you could see all the utilties behind it on the screen, very impressive - I think it was on a documentary about Crossrail stations actually.

I know we get a lot of requests for BIM data at work - anything from cable trays/racking through to valve and actuator data, but I've never really seen how that resulting data is used.

Meanwhile, back at Green Park, this was the situation yesterday (Sunday).
