    Winter tires that don't work in snow

    From NHTSA, four tires are named (but not the Tormenta LMD FSR103 posted above), all with aggressive tread for mud / rough terrain. Note that the manufacturer has not been quick to alter their web based promotional material, from which these images were retrieved. (Edit: After checking the web...

    161 Maiden

    From New York Magazine's Curbed, so it sounds like the trouble became baked in during the course of construction. Also, from another item on Curbed, From Google, it looks like a construction error (above the 10th floor) that someone tried to make disappear. Google Street View Street View...

    Ferry Dock Collapse

    The driver behind the Sapelo Island Marsh Landing/Meridian project was an action started in 2015 by residents of the island demanding the state provide adequate services for the population in keeping with rights and responsibilities. Drayton, et al. v. McIntosh County, Georgia Although the...

    Miami Beach, Champlain Towers South apartment building collapse, Part 19

    At a more temporal level, the collapse is about inept renovations which overloaded a suspended slab, inept engineering studies evaluating a failing structure, and a failure to rein in usage of a hazardous space, i.e. the lobby level parking whose compromised structural integrity was well...

    Two of several images uploaded today. More suspect welding. An image of the gangway center handrail weld is titled "marsh landing transition ramp.jpg". Another photo, titled "marsh landing small boat hinge.jpg", one of the smaller gangways.

    All of the documents are there now so I'm not sure if I saw things correctly yesterday. It could be that I was just in the Vessel Maintenance folder and in too much of a hurry on a different platform.

    Ferry Dock Collapse

    Today I find many of the documents removed from the drop box. The only remaining items pertain to vessel maintenance ( MV Annemarie and MV Katie Underwood), which is irrelevant to the dock collapse. Are we to believe the documents have been pulled into a law enforcement investigation?

    Ferry Dock Collapse

    Cambering the deck pretensions the top chord and likely has minimal effect on the deck weld connections at the bottom chord. It also precompresses the vertical elements. As FacEngrPE (#151) pointed out, the camber is within/close to the elastic limits of the material. Once diagonals are applied...

    ... and the time stamp disappears so now I don't even know what I talking about. !?!? Ok. Found it. Page 5, #97, starting with "Some clarification." If you press and hold the posting number you get a link which you can apply liberaly or conservatively, which ever way you lean. Or you can...

    The supposed engineering drawings which were invoiced and paid will be an issue. I wonder if they will ever see the light of day.

    Ferry Dock Collapse

    This is why more eyes are better. I hadn't accessed fully absorbed that file yet. I wonder what issues can arise in the cambering process. As to the truss type, it was my impression that the Howe distributes the top chord compression across the length of the structure compared to the Pratt...

    Ferry Dock Collapse

    It's not so much that the truss type was different (the Howe truss is actually more suitable than Pratt), it's that an "L" or inverted "T" has limited viability in any circumstance. That two different types were employed in essentially the same project just makes the head scratching more ...

    Ferry Dock Collapse

    No worries, this new forum does not work as efficiently as the old, at least from my user perspective. It is much more difficult to track long threads and even referencing previous posts takes forever, at least if I want to reference the poster and time of post. Thus when I state I posted...

    Ferry Dock Collapse

    I outlined the timeline of project progression earlier (Page 5, Wednesday at 5:21 PM). This is a quote and P.O. for the Meridian landing (Phase III), not the failed Marsh landing gangway. The question is whether the documents and overarching agreements pertain specifically to the failed...

    Ferry Dock Collapse

    Yes, that's who I sent my request to. The response came from K. I. () who owns the box. Perhaps you could send a request directly to her. An additional note was attached, "Please note that various records associated with the law enforcement investigation into the gangway collapse are being...

    Ferry Dock Collapse

    It wasn't a FOIA. It was a "Hey, can you loop me in on the media DropBox?" request and the next day the invite appeared in my Inbox. As the news report I posted the other day exemplifies, the one with the ghost letter, more eyes are better.

    Ferry Dock Collapse

    GDNR has been purchasing directly from Crescent for years. The failed gangway may or may not be an anomaly in that it was wrapped up in a larger contract where GDNR became the eventual owner. These are off the shelf (on demand) items which no-one has questioned til now. They were not custom...
