I understand what attracts people to Advance steel. It is included with our license as well, but I never use it. I work with a few that do. If you are acting as the detailer, it makes sense. The details is what takes the time as you know, so getting the typical Revit models I see from an EOR...
Advance steel may work for some fabricators, but not all. Keep in mind this software is used to control all that fancy equipment. If someone is not an Advance user they may need to re-do the part drawings. At that point, that model is not a great time saver. Most fabricators have their own...
Given it is from the 60's, I would expect a fairly simple design using welded wire mesh.
The treads appear to be precast as there appear to be bolts. Those could be a rivet for the support tab.
I am not sure if the landing was precast. That would be not be as easy to transport and I do...
I would start with the typical section and not the end walls. If you have overhangs on all sides the top of your roof joists will be lower at the endwalls for your ladder framing unless you notch your roof joists for that framing. Cutting your roof joists for ladder framing on flat is common...
We are working on a project where we were provided a raw csv file direct from the surveyor. Normally we are working with professional surveyors that have Civil3D, and they provide beautiful CAD files. Not the case this time. We no longer maintain a license to Civil3D, but need the data in a...
The plate idea seems to work for this. Meadow Burke and others make form savers that use NC thread (tested to 1.25fy). You could simply drill your plate for bolts. I am sure someone in your country makes something similar in metric threads.
Legal or not, do you feel it is a good business practice? Client selection is the best way to protect you from problems down the road, and here you seem to know little about who you are working for. I assume the fees are low, so one problem could eat up any profits you made. No thank you.
Thinking about this some more for some odd reason. I suspect what might have been detailed look like what I have below. That is a standard column with a magic steel piece miraculaously placed in the middle. Easy to draw, difficult to construct.
If I were looking at this I would suggest...
The column reinforcing details seem very relevant to see how constructable this is. The original detail did not seem constructable at all once you start adding vert, ties, and formwork. Now it seems possible, but I think there are some more constraints to think about and include in the discussion.
An 8'-0" cantilever does not seem that notable. Finding someone to pay for this on your typical residential project seems the hurdle. That anchor detail is terrible.
"We are talking about the holes in the base plate." I understood that.
There will always be some mistakes. 15years or more ago we did one where 50% of the anchor bolts were misplaced. The fights that ensued led to some changes in attitude. Now we see less than 5-10% except in cases where...
"another engineer says just do D + 1/2" in all cases" Um, no. Is this still a common problem today? Many of our steel trades send 1/8" thick anchor bolt templates with their steel packages and trades use total stations for layout. They have figured out who pays for these mistakes. Our...
I have never used them, but have looked at them a few times. You can cut the top of the sleeve after your concrete has been poured so they can be filled. I doubt many want to do that since it would result in a two step grout procedure unless you form your grout allowance for a fluid grout. If...
Every ladder I have been on in a plant seems to follow practices outlined in PIP STF05501 Fixed Ladders and Cages. Attachement to the structure is usually more a concern than the plug welded rungs when I have went up them.
