They want to win the job (by being the lowest bid) and get through the building department with as little contact with an inspector as possible. They also want to "use my own experience" to build, and then see what you will do after they do that. "What, you're gonna make me take it all down?"...
Communication is key; get the owners and design team together, state your concerns, explain that no further construction is happening until you
check the design and issue clarifications and addendums, which will happen at an outrageous price and long time frame. This will probably be met with...
I live in an area that has several markets. The markets exist because of geographic diffences. The 'mountain people' with very
stringent building departments (engineering stamp required for literally everything) and the valley people, with little to no
building department requirements. Mountain...
I have never experienced this until now, but this just happened.
I was contracted on fairly complex duplex residential project; went through design and Building Dept Approval and then was
told that they had 'sold' the project to a new developer. My scope of work, as usual, was for design, and...
Looking for some ideas on Heavy Timber Post Bases.....
I'm just not happy with the prefabricated options, or the options we have come up with.
We produced a similar post base as this with 4 bolts into the column....
It was large, clunky, took forever to install and basically not very builder...
In my 17 year career I have avoided pole barns. Until now.
Recently landed a pair of jobs because we need the work. One mid size, one fairly large.
Both jobs ended abruptly with the following converation:
Us: We as engineers cannot do that or your building will collapse. Have you thought about...
On of my jobs has these cracks in the concrete.
Bars are No. 4 at 18 inches on center with proper dowels.
Concrete is a 20 inch wide x 11 inch thick strip footing.
Concrete is extremely creamy (lots of cement) based on observation of the forms.
Concrete guy mentioned that they 'routinely add...
I have a connection that the contractor was unable to bolt because of a field alignment issue.
It is a moment connection. Their solution was to add on this
external horizontal weld line. I'm not understanding how the weld can penetrate if
there is no bevel on one of the plates (or bottom...
I was reading today in an article from Structure magazine that smooth WWF is not a recognized slab
reinforcement in the ACI. I guess I have been doing it wrong for many years. Just curious if this is just news to me,
or if it is commonly accepted with my peers.
Thanks in advance...
@jayrod12 the soils reports in clay soil jobs specifically says don't tie slabs to structure.
It will pick it right up. Imagine 600 psf uplift ability any surface area.
We are the EOR for a house in an area with clay soils.
The soils engineer has identified the heave potential and has made appropriate recommendations in his report.
We have designed a floating slab in the garage.
The contractor asked a good question, that for some reason has never come up in my...
The concept that the top of wall offers stiffness is in reality not true. I see that in many of the responses.
Not being snarky, just saying, there is no stiffeness in a 9 ft stud wall fastened only at its base. Zero.
If you doubt this, experiment in the field some day.
Regardless, I have sat...
Here is a great reference on the subject.

In regards to everyone saying "it won't crack", if you could send me a copy of your E&O insurance and your stamp with signature, we will keep the job moving...
We design residential wood framed houses frequently with vaulted interior pitch (known as a scissor truss).
Does anyone have a reference explaning or experience dealing with how far the truss can kickout (horizontal deflection)
before the gyp board ceiling seem rips? In the attached example, the...
Has anyone ever used facemount hangers instead of top flange hangers for the member
haning into the I joist packout? Why can I not find that (facemount) hanger detail
on any of their literature?
After happily paying $90 for the ACI 360R-10, Guide to Design of Slabs on Grade so I
can actually "design slabs on grade" I am now having regrets. No where that I can find, does it give a formula or table for
minimum reinforcement requirements for plane old cast in place slabs on grade.
I...
