Also, you need someone to directly review how your log cabin is built. I have seen several log cabin designs with a note saying they were not engineered nor are they intended to meet local codes. I don't know how that is allowed, but I have seen it.
Walls don't tend to "sag inwards"...
I use SSMA and never had a problem with wall studs. I am not aware of it applying to PEMB Z or C sections. There are several parameters that are difficult to call out unless you are speccing around some supplier or code. The yield stress of the steel, return lip radius & length are examples...
PLAUD transcribes your recording but it does offer AI summaries and other specialties I rarely use for the same reason. I always proofread what it transcribes and generally have to make corrections but at some point, I either pick different words or it eventually figures some of them out.
I do...
That is in line with projects I have done with similar scope. Once you learn what areas in general have plastic soils and that appears to be the main issue for the project, there are not a lot of calcs unless the structure itself is really articulated. Most of them are basic residences. The...
Check into PLAUD. A little practice and diligence in what/how you say something may work. It helped me on projects with a lot of pictures. I use a distinct non-existent word (ChaCha for example) and then my picture description. I had to document every noticeable defect in a property along...
Of the ones I have been exposed to, I don't think I could even ball-park a fee structure. Each one is rather unique and the depth of my involvement varied so much. Other than an hourly rate and your estimate of how many hours this unique job will take, I know of no other methodology. But you...
Chance Anchors is good one to look into for basic training. It may be Hubbell/Chance now. My unicorn from years ago sold that product. They have some training and many other anchor sellers, refer you to them for information rather than their own product's resources. That always scares me. I...
I agree that you must venture out in this business unless you have plenty of the type of work you enjoy doing. There is nothing about underpinning that is "mysterious or secret". The systems respond to stress and strain like everything else does. It is a matter of getting familiar with each...
I am having a hard time following your drawing. I cannot tell what all is existing versus new. Also, cutting sections at each interface of old to new would help. This would include new and old foundations.
Is there currently a solid wall where new meets old in the garage area or is that the...
I assume you are only looking at the tower being unstable due to the vertical weight of the materials, not falling over due to a gust of wind from the side or someone shaking the item the tower is on.
The main parameters to start with are density of the materials, plan view dimensions...
This would bother me more. I am buying a new house, and I cannot see the drawings or specs!! Is the house still under construction? If so, how can he justify keeping them hid. Does the city have a set? I would insist on having my own set of drawings and specs. Even if I had to pay for them...
Were the other installations required by the contract or drawings? If not, it would bother me more just because I would feel like I got a lesser service, UNLESS I beat him down on price but the others did not.
As pointed out by EngDM, the VB does change the coefficient of friction but does not make it zero. Also, the surface of the base is not glass smooth. Subgrade drag is real, just try to pull a small piece of concrete across level ground that it was cast on.
One thing I preach about to...
Since the sill is PT-I see no argument and not much need for worry. Similar to other comments, I have seen thousands without any damage and have never seen one with a sill sealer installed that I recall.
Being a fact and actually occurring are 2 different things. Water can travel through...
What circumstances on your project would have told the builder to install the strip? I do not think the building code requires it unless you are going for some high-end energy rating. I can understand your contract or drawings requiring it and if there is a code that the builder was to adhere...
I am not familiar with the notation of "10M", what does that mean? Is it metric sizes?
I have designed many PEMB foundations but have never had to cut out an existing one that was relying on the hairpins for thrust. The only one I ever had to cut out had the thrust completely controlled by...
Are you saying the tip-to-tip distance of the hairpin is equal to the bay spacing?
PEMB DL&LL thrust magnitudes are mostly governed by clear span of frames (shorter the better), frame height (taller the better, yes taller), Roof Snow versus Roof Live (less is better) and bay spacing (less is...
From what I read, the 14.42 represents 14,420 lbs of axial force the stud can take while being subjected to the 50 psf lateral load. In other words, it is the vertical weight the stud could support, not a deflection.
The bottom says since there is no superscript note (1-4) the deflection meets...
