Building A Bridge

[bindian]

The green we tried as a sample looks better in real life but I still am not sure if it is better than the red.

Koop,
Paint it one color for inbound traffic and the other color for outbound traffic. Then one color can grow on you or leave it with two colors.
hugs, Brandi

Neat looking bridge. We recently had two wooden railway bridges donated to us. Sorry I don't have any pictures. I can tell you they were being used up to the day they were replaced. They were only replaced because the railway double tracked that section. Our bridges will never carry trains only people.
We had to hire an Engineer to design the footings.
I wonder if the steel in your bridge has serial numbers,foundry name or a code stamped in the steel this might allow you to research what type of steel it is. All rail has a year built, serial number and foundry this is why the scrap man loves old railway track makes great rebar.

...I would note that the event in Wisconsin has only one thing in common with this thread, and that is they both involved bridges.

Your wrong they these two events have TWO things in common, they were both bridges, and the powers that be did not do what should be done to protect the public.

Here we have a bridge builder that refuses to do it right, and Wisconsin also had info and reports but failed to act - both KNEW what should be done, and both refused to do so.

In wisconsin - A key factor with this bridge is that it was an older non-redundant design, ( NOTE THEY KNEW THIS ) which the engineers call "fracture critical". The term "structurally deficient" is an engineering term that can be applied for a variety of reasons. ( THEY ALSO KNEW THIS AND DID NOTHING ) , though none of them would build a bridge like that today knowing what we know since 1967.
( Oh, and they didn't shut the bridge down )

So how did that conversation go "Hey dude, man is that bridge bogus, I would NEVER build one like that thing"

ALSO.....Inspections as far back as 2000 on the Wisconsin bridge identified both corrosion in the steel and a lot of cracking, says Stehly.

HEY here's an idea...lets let people keep driving on it.

Tell that one to the families that died. Uh, we knew the bridge was falling apart, but we still let people drive on it.

And now we have someone that refuses to engineer a bridge, yet wants to select a pretty color.

I've got a color, how about blood red!

I suppose you've convinced the jury with your final plead...

Koop, do you want the abutments what is seen in this picture http://www.tractorbynet.com/forums/attachments/projects/86664d1191174050-building-bridge-abut.jpg
to carry the bridge ?
I dont know on what these walls are resting, but it looks like a bit fragile to carry several tonnes of bridge.. ??

Koop:

Regardless of the "sky is falling" posts I think it's a great project and can't wait to see it all set. Keep the pictures coming.

Well, its green, green, green they say on the far side of...

OOPS, sorry... Either red or green will "work" but I think the green is clearly superior in appearance.

Those stick built forms sure look like a lot of work. Have you ever used "Snap Ties" and cam locks? The cams locks and accessories are usually available as short term rentals. They sure save on materials and effort while giving excellent results.

Brandi,
You had me laughing for a long time, thanks for the reply.

RAILTRAC,
I see Lackawanna stamped on all the steal, but no more info than that. Is there a particular place I might look.

Kendall69,
You still just don't get it. The substructure for this bridge has been designed with an engineers help. It is at least 50% bigger than the substructure on which it set for 70 years. If you could see through your self righteous fog, you would know my problem with engineers was that they were not willing to divulge their safety factor. Get off your high horse and get in the spirit.

Renze,
Your input has been invaluable to me. You are looking at a 2' thick abutment wall which is 10' tall and 15' long. It sits on a 4' thick, 8' wide and 17' long footer. Both have two mats of 5/8" rebar on 1' centers. This matches or is greater than the state bridges up and down steam from us. Let me know what you think.

Khd,
Thanks. For some, the sky seems to always be falling. I will visit the project this weekend, so I will post new pictures.

Patrick_g,
We hired a VDOT contractor to do the work so the stick built forms were his call. As a builder myself, we use metal forms but we do not do a whole lot of concrete work. (mosty footers) Tell me more about the "snap ties" and cam locks.



We have settled on green for the color, and the bridge was primed today. New pics coming soon.

Bethlehem steel was a big steel plant in Lackawana, NY just outside of Buffalo. I don't know much about the plant as it was all but out of business since I started going that direction but I would think the Lackawana stamps are for the town. Maybe one of the othere WNY'ers will have a better idea if they read this thread.

Bethlehem steel had may fabrication plants.
The golden gate was built in pottstown pa and shipped to cal

and Bethlehem bough Lackawanna steel company
