Every construction company does concrete work at one level or another, but certain situations require a much higher level of experience and capabilities, a bit of heavy lifting so to speak. We know this is true, because Humble has been continuously improving our industrial concrete skills for more than a half century.

Industrial concrete construction is a specialized skill. So when a longtime customer decided to add an external overhead rail crane to their facility, they immediately called Humble. This job was almost 100% concrete work -- the kind of concrete work that makes you glad you have 50 years of expertise behind you. This was definitely what we like to call a Heavy Concrete project.

Think about it. To create a structure that will support a heavy duty overhead crane for a heavy industrial operation, you're going to need heavy duty amount of concrete. When finished, we placed more than 3,600 yards of concrete on this project. Here's how it came together. We built two spread foundations that are each 18 feet wide x 400 feet long with piers 25 feet on center. That's to support the huge piers that the crane structure stands on. The piers themselves are 11 feet long x 3 feet wide and 12 feet high.

If that wasn't challenging enough, each pier needed to have 8 anchor bolts precisely located to match up and secure the crane structure. These bolts were 1.5 inches in diameter x 2.5 feet long. When the concrete work was finished, we wrapped the piers with steel plates to protect them from the inevitable collisions with the payloads that the crane will be lifting.

The driving surface where the vehicles travel through to load and unload also required special heavy construction. Based on the extreme conditions it would need to endure, the concrete pavement design was 12-inch thick concrete with a double mat of #6 re-steel 12 inches on center each way to protect it -- heavy duty pavement!

Downtime was not an option.
As always, Humble started this project by consulting with the client to establish a construction plan. In this case, one of the primary needs was to ensure there would be no interruption to their ongoing production. Among other recommendations, Humble defined a four-stage construction process where one quarter of the project would be completed in each stage. This allowed for steady progress on the new project while allowing for ample room around the jobsite for ongoing operations.

This was another job that makes it clear what we mean when we say we Raze the Standards. Challenge us on your next construction project, and we'll show you how we can Raze the Standards for you too.
