Anyone has more info on this bridge collapse? Did it collapse while lifting? Any info is appreciated.

Thanks Engimental!
That is a great resource! Who made this? There is no copyright or any credit to anyone.
When it comes to considering the pump run and rest times, di you spec 1 min off 1 min off or 2 mins on 2 mins off?
Fellow engineers,
I am working on a small project where a bit of parking lot is being regraded to create a loading dock. This loading dock will slope down about 4 ft but the overhead door and opening will remain raised to current grade. As a method of storm water management, the architect...
Thanks STpipe.
That is a great direction. I did not know that Canada has its own code compliance assessment service by our federal government, though it is not surprising.
I have recently been asked by a company if I would like to be the engineer of an American system that they are looking to be the distributor for here in Canada. The system is made up of cold rolled aluminum extrusions and insulated metal panel roof.
For the metal panel roof, since I have never...
Hanging canopies in Canada are tough to design because of the snow load. JLNJ made a good point about the drift. That should be accounted for.
We are building a 5 storey building in my area with the same hanging canopy. In locations where we have a block wall, the engineer spec'ed a cast in...
I was able to do it with 1 page and worked like magic. The issue now is when doing to multiple pages - I tried a set of 27 - it takes forever to print as an image.
I am trying to help the developer save money printing internally since I work for them. There is no one to bill these printing...
My local printing house is charging $0.50/sq ft. The site super always wants extra copies or multiple sets and so adds up quick compared to the price we pay for paper and toner.
Thanks I was able to automatically reduce file size by 30% then if I decrease the dpis to 150 each then I am at 48% of the original size. So far the best results! I am home by now and will have to try to print it tomorrow!
It is a Lenovo i7. The plotter is not the newest but we print all...
No photos, a lot of hatching though. The elevations are quite heavy as well and also has lots of hatching.
Tried deleting all the hatching - got another 8% off. But we need some of the hatching in there so not a great solution.
Much appreciated LittleInch. I the CAD files so I played around myself.
Reducing the size of the page to 24x36 reduced the file size 8%.
When adjusting my printer settings, I had 2 options to change dpi for: Vector Quality and Raster Image Quality. I was able to change both all the way down to...
Sorry for the confusion. No, I am working for the developer to develop the land in a construction management role.
Excuse my ignorance. For the dpi setting, is this something I can change on my side on Bluebeam or something that has to get changed when printing from CAD to pdf?
The original...
I am representing the developer in this case, not the engineer. The architect is sharing a PDF file that is so large. Each page is between 1.5MB to 3MB. It is so large that my printer/plotter has a hard time printing more than 4 pages at a time. I tried sending it to local printing houses and...
That would be quite the footing! Imagine for every stall making a 20' long footing. I believe the single support cantilever carport idea is not economically sensible in an area with a 1.2 kPa snow load.
Maybe with the double support, I will work on designing a smaller pad footing to see if it...
Good Evening Engineers,
I am designing a commercial carport with supports only at the back. Below is a picture of roughly what I am trying to achieve. The location has a relatively low snow load of 1.2kPa but it poses a challenge! I have tried modelling a couple of options and I am wondering...
Great point jayrod12, not how I had read it.
When it comes to a load bearing wall, column or footing, I wonder if then you would use the area of the floorplate which is more likely to add up to a number higher than 80m2.
Below is the clause and a reference from the clause. As I read it, this OWSJ is a "structural member supporting a tributary area of a floor."
Bones206, I wonder if you would be correct in interpreting only columns as being a "structural member supporting a tributary area of a floor."
The floor...
I wonder if the original design in the 40s/50s had higher live loads than today's minimum requirement by code.
When you did your midspan new beam, I imagine you sat the the top chord on the new beam? If so, do you know the procedure for the work i.e. did they have to shore both sides of the...
office 1.9kPa
Storage 4.8kPa but the NBCC has a clause - 4.1.5.8 Variation with Tributary Area which allows for a factor to decrease load on storage buildings based on the area. Live load resulted in 3.6kPa. So the live load increased but did not quite double.
Dead load remained at 1.8kpa
So...
