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.
Most basement walls are furred out so you do not need to look at the concrete. If so you could support the load with steel or wood framing based on the load.
Thanks XR. I am curious what thickening you might have for something like the example? The bldg is 40'x80'. We rarely do these. Way too much risk for CH soils and frost. The pay is crap too. There is another handing out a simple un-thickened design like tick tacks, so I thought I would...
I was asked for a small thickened edge slab design, and I decided to look at this a bit closer than some times in the past. I found some old guides for this type of design, but I did not find any that illustrated the forces in the section. I decided to create two models. A unit width section...
We work with a consultant in Austria, and use dropbox with him. It still works very well. I use a gdrive as well. I have never tried Onedrive myself. Microsoft seems to screw up so many things so I always hesitate. I have several clients using OneDrive.
Meadow Burke and Dayton Superior make an anchor like JAE shows. These are tested for the minimum anchorage force. It is hard to find a cheaper option than the grout tube.
It is common to see the panel sit directly on the footing and they form a blockout in the slab for the wall. If only...
The crushed stone idea is horrible unless your soils are free draining. I doubt they are since CIP piles are suggested. The voids in the rock will fill with water, and your pile will most certainely jack if it freezes.
At one time our geotechs recommended extending the pile about 4 times the...
Considering <$10k constrcution cost, I would write up your opinion and move on unless some aspect is related to work you did in the past. Here the argument seems to be you have a conflict becuase this is a notable client? A conflict would arise if you had something to do with whatever has...
Over the past many months I have been learning how to use Grasshopper. If you are not familiar with this, it is a graphical programming tool. You can link this with Revit, Tekla and several other software packages. Most modeling software in the AEC world extrude defined shapes along lines...
I am in Canada. We are a metric country, but most residential trades still work in imperial. It is very weird, but it has been that way for a long time. Our rebar is all metric. Go figure.
Nobody specs anything to do with the drywall here. The joints and layout is all up to the tradesman...
Less astethic? You do mud your joints? The joints here are mudded in almost all homes except for modular homes. In modular homes they have plastic pieces that cover the joints. In schools they use vinyl covered drywall, but that is for durability and has nothing to do with shear loading...
The normal drywall practice is to have joints at the centerline of a single stud. Our code at the time suggested a second stud in cases where the drywall was being used as as a shear element. Having hung drywall I know how easy it is to have your drywall only bearing on a stud 3/8" or so...
We tried using drywall as part of our lateral system years ago. Nobody I know uses staples, but maybe the modular trailer companies do. The problem we had since this is not standard practice is nobody informed us of when the drywall work was being done. In our case we had shown extra studs at...
I suspect most precast manufactuer's have endless bulkheads for this problem. Slopes are normal, and that is not a lot of work. Sloping the bearing is more work given the reality of what one must do with the rebar and forming the bearing. If the bearing is 3" or 75mm, the slope distance over...
What are the anchors? Hilti, HCA, Simpson? Hilti limits the bolt size to 3/8" for a this type of embedment, so two bolts would be trickey. Hilti Profis works well for this.
