    Lifting Certification for Existing Structure

    A long time ago I used to do some lifting and shipping design work for modular plant equipment. They came in two flavors, skid mounted equipment (which sounds like your case here), and equipment that had temporary shipping and lifting steel that was bolted on and reusable for the next job. You...

    Roof Framing 3 inch Deck, Beams at 10ft spacing

    I used to work in fire protection. Never had framing spaced that far apart, but I can try to extrapolate from what I know. There are hangers that can be installed in a metal deck. I imagine this would be fine to support some smaller diameter pipe, like 1" arm overs, but are you going to have...

    Price model for engineering office

    I used to work as part of a design team where the team members had to log our time spent vs. the budgeted hours. Every now and then some manager would be trying to cut the budgeted hours. When presented with something along the line of "this will take 6 months and require 6 people" it is easy...

    Operating inside a structure during partial demo/renovation?

    I am assuming the old joists will be replaced with new joists. Don't walk under a live load is like OSHA 101 that is in every tool box talk the day of any significant pick. I think at a minimum you have no choice but to shut down operations when placing the new joists. Maybe you can come up...

    Cracks and Leak in Cinder Block Retaining Wall

    Maybe I need new glasses, but it looks to me like the top of the wall is out a bit. All in all not bad for 50 years of dealing with lateral pressure from piss poor site drainage, but I don't know if I'm jumping on the clean bill of health bandwagon. Especially with the consequences of failure...

    Vehicle Bumper Overhang affecting sidewalk ADA width

    My guess is your worst case scenario is a truck backed in. I have a 2015ish F150 super cab (back seats with suicide doors) and the 6.5ft bed. Front overhang is ~2ft and rear overhang is ~4ft. I try to find a space at the perimeter of the lot and back in so I can hang the tailgate over some...

    Use of "However" in Engineering Reports

    However can be used to start a sentence. There I did it, turn me into the grammar police. I'm already looking at consecutive life sentences.

    Use of "However" in Engineering Reports

    I like to use however when I need to make two different conclusions and I have important information that may mean different things to different portions of my work. Example: The damage to the roof framing is a result of snow load The rafters as built are over spanned for current code...

    1" hole drilled in bottom chords of wood truss

    KootK, You are too kind scabbing around the wire and letting it stay. Need to get the electrician out there to pull it before repair and reroute after repair so they can see how much of an issue this became. Best case scenario is this was some new, untrained, and unsupervised helper that...

    1" hole drilled in bottom chords of wood truss

    The truss manufacturer doesn't want to evaluate this? I know some of them have standard repair details ready to go. MiTek has some at the link below that you could use as a starting point. https://www.mitek-us.com/resources/engineering/roof-truss-repair-details/ You could assume the drilled...

    Purpose of both the uplift hanger and strap at ridge connection

    Disclaimer: I'm not too familiar with the hanger and have never done an I-joist roof. I was taught that the purpose of the collar tie or strap was to keep the rafters from separating at the ridge. To me separating has an upward component and an outward component. For those hangers the outward...

    Multi-story Residential Steel Columns

    I've seen columns continuous through two stories on two occasions. Both were installed during new construction so they were just lifted into place before the roof was on, no real issue if you sequence the construction for it. On one occasion I was there for an unrelated reason and I picked up...

    deck post clearance

    JLSE, I missed the part in your OP about the posts being untreated. There I go assuming things again... The post in the foreground appears to be discolored around the base. The post in the background is set atop a 2x on flat as if it rotted at some point in the past and someone trimmed the rot...

    Disgraceful behavior from an Engineer

    This is the part that jumps out at me. Is "terrible discrepancies" Engineer B's words or yours? Using words like terrible, significant, etc are a red flag for me. If there are discrepancies they should be quantifiable, this is off by 50%, results in non-compliance with xyz code, etc. I see...

    deck post clearance

    I will be honest, in my mind I was picturing in my head a 4x4 post on a little 6" or 8" sonotube pier. That is what I call a great philosophical engineering question that I could burn an hour or two on the phone discussing with a few like minded engineers I know. But you started your post with...

    deck post clearance

    JLSE The code language switches from pier to floor, so I interpret that as a literal floor, separate from the pier. Say the piers were surrounded by a slab on grade, then the piers need to project 1 inch above that slab. I think the or in the concrete floor or exposed earth statement reinforces...

    Are Permitted Construction Drawings Public Record?

    I recently had to file a FOIL request to get the permit drawings for a private residence. This jurisdiction allowed anyone to request site plans, but anything with a floor plan on it required the owners consent via a separate form. Seemed like a fair way to do things. It's more paper work and...

    RealPost for (true) exterior use ??

    No personal experience with this product. FWIW the website also has RealCorner and RealTrim which are targeted at exterior applications. The installation instructions of RealTrim do refer to the product as "treated" while the RealCorner installation instructions do not. Rake/frieze boards are...

    Texas’ Big Freeze: The 2021 Power Crisis and the Lessons Learned One Year Later

    The concept that companies are people is one of the biggest steaming turds I have had the pleasure bearing witness to. Companies are legal constructs designed to shield the actual people from liability, and should not be a vehicle for the owners to anonymously spend their money willy nilly. If...
