* Schalungsplan
* Trägerplan
* Aussparungsplan
* Elektro-installation

Hi Natter,

Hello @natter,

Doesn't the archive have a copy function ?
So a way to order a scan/copy of an archive ?

Sadly, not yet. Since fall 2017 I have been/are struggling with health-issues (I'm in and out of hospital these days), so it has not been possible to make the trip yet. Hopefully, I will get an opportunity next summer.

These items are not kept in an archive (although I suspect there are duplicates in the OT-archives at the National Archives in Oslo).
There's a very limited staff and (as far as I know) very limited resources for making copies at the site (just an old b/w A4-Xerox copier).
Handheld camera is also no good due to the large size of the drawings combined with the faded print and strong overhead light at the premises. You can see examples on the results I have posted in the links here: viewtopic.php?p=2085849#p2085849 (that list is also an partly "index" of the material to be found there).

Since my last visit, I've purchased an A3 flatbed color scanner with detachable lid (see attached photos). I think this will be very suitable for scanning the drawings at best quality (the M145 is only one of several sets, so I think it will take a couple of days). However, it's hard to bring this on a trip to Oslo unless I'm going by car, hence spending a part of the summer vacation is probably the best option (health-situation permitting...).

PS:
Other forummembers have examined the material as well, so perhaps copies of the M145 drawings have been made by them?
If anyone is planning a trip to Oslo, I'm happy to provide information on how to get access (you should make arrangements before showing up there).

I use this too, but then with the A3 printers in the office which also scan.

Other option is a A0 format scanner, they are hard to get second hand.

I have several scanners, including a A3 multifunction printer, but it is (not to mention a A0-scanner of any type...) not suitable for travelling. When you need to bring a scanner with you to a facility, a light flatbed-scanner is the only option.

In addition to my handheld compact- and DSLR-cameras, so far I've used a light A4 flatbedscanner (Canon CanoScan LiDE 210) and a handscanner (Sovos PS-410-2). They are great for the job in most cases, but when you're dealing with drawings of very large size (up to 2 metres) of variable condition (ie stiff/damaged paper which is hard to handle), it's just impossible. Even if you can use them, it takes a lot of scans and a huge "splicejob" to create the complete image afterwards.

The new A3 flatbedscanner I got (PlusTek Opticslim 1180 A3+) is the best option I've found so far in terms of getting a larger and unobstructed flat scan-area to handle large sheets of paper/ books/ binders etc, and at the same time being small/light enough to carry. Unfortunately, it's just too large to bring as carry-on when flying (I haven't been able to find a fitting padded bag either*), so I can't bring it to Oslo unless I'm going by car or train.


* I'd be greatful for any tips/recommodation (the size is 58 x 40 x 6,5 cm)!

hope you feel better soon!
good luck

Maybe this type of scanner is a solution: https://www.conrad.nl/p/renkforce-w4s-w ... 7&vat=true

You can make A4 scans from the A0 and join them later.

Well, if you read my previous post properly, you'll see that I have one like that which I often bring on visits to libraries etc (most archives will not allow you to use such tools, and very seldom a flatbedscanner unless it's provided on site).
The handscanner is a great tool, but not for scanning large sheets as it's impossible to get 100% straight scans, thus making the splicing job afterwards much worse compared to splicing perfect scans from a flatbed.
Also, the sheets must be completely flat to get a good result, and these old german drawings are very thick and stiff paper with cracks and folds that are impossible to flatten, thus making the use of a handscanner practically impossible.

Scanned these today.
For the time being, here are some photos by handheld camera (very poor quality, as the images also has to be reduced to fit the forum requirements).
