A good night's work

This is kind of cool, demolishing a railroad bridge overnight.

Tis cool. I have operated the shear units on top of the bridge and the hammer that took down the center pier, but it was always a day job.

Amazing what some fluid under pressure can do!

Wow that is pretty cool. I saw this in the news here in Phoenix so it's cool to see a video of how they approached it.

I think this is proof that too many road workers take way too long to build things. I remember seeing a highway here (US60) in Phoenix/Tempe taking way too long to build some on ramps.. It seriously took months.. wtf. Granted this is taking apart and I'm talking about building.. but seriously how hard can it be? Pile up some dirt at the correct angle, grade it, and then pave over it.

You obviously know nothing about building roads or bridges...

(although you DO have the basics down... )

However, you skipped a shit-ton of things that have to be done before you even start to pile up the dirt.

True.. but 5 months worth of time? I could understand a couple of weeks! I know there is more work to be done such as surveying, etc...

Erosion control, surveying, traffic control, demolition, realignment, and then rebuild. Sometimes materials aren't good, and it requires extra work. Undercutting, or special fill.

Edit:
The company also has other jobs that need to be done, that also take equipment resources. They usually have a time period to finish the job in, and that's usually much greater than the bust ass as fast as possible time, so it gets slowed down due to scheduling.

Plus...the contract might restrict how much work can be done in a specified period of time (hours of work) or, the contract may not be due to be completed for a long time...so the contractor can work on it a bit at a time...and utilize equipment and manpower on other jobs.

Depending on the job, electrical may have to be re-routed, water and sewer lines moved, even petrochemical lines may have to be moved...or protected.

Few people realize what's actually required in building roads and infrastructure.
