I was hoping the collective good could provide me with an independent second (or third, fourth, fifth, etc.) opinion. We are designing a building immediately east of the building shown in the center of the 1,500 foot circle (see attached image). Our building will have a mean roof height of...
I have designed a lot of PEMB foundations in fat clay that are founded on under-reamed or straight drilled shafts in fat clay. All but one of these foundations had simple pinned connections for the rigid frame to the foundation. One previous (and now another) have moment reactions transferred...
A client asked me to look at a building that another engineer designed for him. The building is a pre-engineered metal building with a concrete tilt-up wall panel facade. The typical concrete panels are 25' wide (one bay width) and approximately 25' tall. The panels have embedded (8"x8"x3/8")...
I have a U.S. based client that is working on another project in the country of Brazil (which I am not directly involved in). They have asked me a question I could not answer nor easily find the answer to online, so I will pose it here.
The contractors in Brazil classify concrete floor...
I had a contractor call me today asking for a rule-of-thumb on determining the dunnage footprint size and thickness for crane outriggers supported by a slab-on-grade. I didn't have one to provide him, but to say that I could do a FEM analysis to figure it out for him.
This contractor has had...
I am pursuing a new type of project, but am having trouble finding the right references and guidance. The IBC reportedly requires that storage racks over 8 feet in height be designed and structural calculations provided by a PE. I can not find this requirement in the IBC. Can anyone point me...
Many years ago I worked as an assistant project manager overseeing architects and structural, civil, MEP, and specialty engineers during the design of building projects. We typically based our overall fees as a percentage of construction cost with certain percentages due for SD, DD, CD, CA. We...
What are the tolerances for typical residential floor surfaces? I am aware of the difference between levelness and flatness, but don't have a copy of ACI 117 which I believe states the tolerances for concrete slabs. I also need to know the same information for elevated pier-and-beam wood...
I am designing a load bearing CMU wall that is 22 feet in total height. At the 11 foot elevation, the roof on the west side of the wall is connected to the CMU wall by means of a steel beam every 20 feet. This steel beam is supposed to be supported by 4 anchor bolts embedded in the CMU wall...
I am in need of some good reference recommendations.
My project consists of a 10-foot diameter by 29-foot deep concrete caisson. (To avoid confusion, this is not a drilled pier caisson, but is the kind where it is essentially a pipe installed vertically.) The soil is stiff clay with a sand...
