    Business registration / taxes

    Pham: Thanks for your reply. This is very helpful. My office is in PA. 98% of my revenue comes from MD. My business was founded and registered in MD. Since my office is in PA, my accountant wants me to move my business entity to PA and register in MD as a foreign S-Corp. He thinks it will...

    Business registration / taxes

    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...

    facade EIFS detail question

    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...

    AC unit support bracket fastened to the side of the existing wood outrigger at balcony

    I did this design, which is loosely based on an a/c bracket support that I found online. I would have just spec'd out that wall bracket but it was calling for 3/8" lag bolts and I wanted to use these 1/2" threaded rods so I could utilize the Simpson Tension Tie. I am open to criticism.

    AC unit support bracket fastened to the side of the existing wood outrigger at balcony

    I have a residential client that wants to replace their existing balcony. The balcony is constructed of (2) LVLs outriggered from the 2nd floor framing. The plan is to demo the existing balcony; install (2) Parallam Plus PSL outrigger Beams (secured to bearing wall at rear of garage - backspan...

    High-rise floor slab construction (circa 1920); structural clay tile?

    @book that webinar was awesome. I feel like an expert now. Thank you for sharing!

    High-rise floor slab construction (circa 1920); structural clay tile?

    When used in a floor system, are these tiles always just filler/formwork/fireproofing? We want to install new vertical openings in the existing floor. I believe the floor system is comprised of steel beam girders spanning to wide flange steel columns, and then the small steel purlins spanning...

    High-rise floor slab construction (circa 1920); structural clay tile?

    I think it looks like "standard flat arch combination"

    High-rise floor slab construction (circa 1920); structural clay tile?

    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...

    Tall Parapet

    Cliff... I too had a feeling that this was the way to go. I designed this 2 years ago and it sat on a shelf. Now they want to issue for permit and I'm having second thoughts about the whole design. I am married to using the steel bar joist roof, however.

    Tall Parapet

    Brad: The angle brace occurs above the ceiling line (ceiling line not shown in the detail). I am showing the angle brace to align with the tie rod that supports the canopy.

    Tall Parapet

    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. My hangup with option #2 is that I am concerned that a...

    Contractor will not provide rebar shop drawings?

    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...

    1 1/2" roof deck - support at all edges?

    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...

    Terminate steel K-joist bridging at LG Metal Stud Bearing Wall?

    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...

    Fiber-reinforced cementitious matrix (FRCM) on Structural Tile (aka Terracotta) Bearing 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...

    Permanent Sheet Pile or Underpin?

    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...

    Backfilling basement of demo'd brick "rowhome"; Foundation Drain

    JAE, Thank you for the thoughtful, thorough response. Regarding your point #5: Technically, "my building" is the one they demolished, so we are all good regarding the property line. FWIW - the city is working off of a "new weather wall specification" and this is the first time they are...

    Backfilling basement of demo'd brick "rowhome"; Foundation Drain

    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"...
