We had a series of (6) rowhomes burn down. There is now a 90' wide lot between the remaining rowhomes. My job is to design a ~90 foot long concrete retaining wall to separate the existing sidewalk from the monstrous "pit". We are retaining about 6ft of soil. The retaining wall design is easy...
I am working on a single family house ($$$$$) where they want a 20ft x 60ft building with a very steep roof pitch (24/12) and a vaulted ceiling throughout. They want the roof thickness to be shallow (12 inches).
There are no opportunities for shear walls in the short direction. I came up...
I designed a new construction church back in 2021. It is being built today. The contractor is making major changes on the fly without approval. We just "found out" that they started building because the architect happened to drive by the site.
1) The foundation has been poured without...
I am not sure where exactly I should post this, so bear with me, please. My accountant is telling me one thing, but I disagree with him.
Does anyone know if you need to register your business in every state that you do work in? I think the answer is yes. So then, does the company need to...
Is there a way to install wide (or maybe the correct term is deep) furring strips on the outside face of a CMU block wall, and then put EIFS over that, so that it looks like the upper floors are cantilevering ~12 inches? In other words, is there a way to "build out" the outside face of the CMU...

This is an existing 10-story building (circa 1920, Downtown Baltimore, MD). Can anyone recognize the structural system used here? Are those clay tiles structural? It doesn't look like the "TYPICAL ONE-WAY COMBINATION FLOOR" referenced in the thread linked below...
Seeking advice on best option for framing a tall parapet above storefront opening. Option 1 shows the block continuing to top of parapet. Option 2 shows block stopping 1 course above joist bearing elevation and metal stud framing above.

I did a fairly simple project. It is a 1,500SF,1-story addition to an existing building. The foundation consists of strip footings and slab on grade with WWF. Our general notes require that rebar shop drawings are provided. Our General Notes read: "if shop drawings are not provided then our...
In the below image, imagine the steel beam aligns with the end of the roof deck. Do I need to provide a continuous angle, welded to the top of each joist, such to attach the metal deck to?
I have seen countless times when engineers do not provide an angle here to support the deck edge.
WHen...
I have a small 1-story "box" building with a steel K-joist roof bearing on LG metal stud walls.
When the bar joist are parallel to the metal stud wall, are you supposed to terminate the joist bridging at the metal stud wall in a similar manner to how you would terminate it at a CMU block wall...
Sometimes structural clay tile is used for the construction of party walls in early 20th century brick rowhomes. Sometimes the old rowhomes collapse or are demolished, leaving the party wall exposed.
Can FRCM be used to reinforce an existing Structural Clay Tile party wall (aka, "structural...
I am writing a proposal for the design of a new 3-story commercial building with basement. The new building will be constructed on a vacant lot between (2) existing buildings. Building #1 is a large brick "house" circa 1920 that is currently used for commercial purposes. Building #3 is an...
I am working with a an old commercial building (circa 1900) with exterior brick bearing walls. The adjacent building was recently demolished. The buildings were abutting each other, but they did not have a shared party wall. It appears that each building had a minimum 3-wythe thick (~13"...
Could you theoretically have slab leave-outs (for future plumbing) in the yellow highlighted areas of the foundation plan?
Assume that you do not have columns creating thrust in the north-south direction.
I have a beam that must be spliced about 5ft off of the column to accommodate the slope of the existing roof. The beam slopes up to the CJP splice point on both sides. Can I design this beam as if it was a continuous, simple supported member?
I have an existing facility where the client wants to install a CMU block fire wall partition on the double tee slab. The building is circa 1973. The block wall will run parallel to the tees and will be centered between the tees. Is this something I can conservatively calculate based on...
I am seeking advice on whether or not I should take this on. I have done bracing for tilt-wall panels in the past, so I understand the basics.
I was asked to engineer a bracing and shoring scheme to brace existing stone facade (about 8 inch thick) during renovation of existing (small)...
Would you typically specify epoxy coated rebar in a concrete headwall for a pipe culvert?
I saw a note saying that the headwall rebar should be epoxy coated when doweled into the roadway. Otherwise, I believe the rebar is typically not epoxy coated. Right?
Hello!
I am working with a 1-story buidling whereby we are removing a steel column. Joist girders are bearing on the column. If we elect to temporary shore the existing steel joist as needed to remove the existing girder, is there a standard practice for how much of the girder you remove...
