Teamwork pays off

It’s not quite like a Giants baseball game out here, but our crews at the Calaveras Dam Replacement Project sure know a thing or two about the importance of teamwork.  Just like base coach Tim Flannery uses hand signals to communicate on the field, our Calaveras Dam workers use the same method to communicate to each other at the site.

Since Friday, we started filling concrete in the new shaft which is an important function for the new Calaveras Dam.  The shaft is part of the new intake tower which moves water from the Calaveras Reservoir through the adit tunnels eventually treated to become our drinking water. The level of noise and limited visibility in the shaft can be challenging, so our workers rely on hand signals and radio communication to mobilize.  Our workers signal the crane to lower a bucket full of concrete into the shaft, and then workers below fill the wall forms with concrete.

The shaft is 152 feet deep and over 720 cubic yards of concrete will be placed once it is completed. It takes approximately a week for the concrete to reach a specified strength before continuing, therefore the concrete work will be completed in 16 foot lifts at a time through March 2013.

For the San Francisco Giants, teamwork wins championships.  As for our workers, teamwork builds progress for the Calaveras Dam Replacement Project.  Congrats to both teams!  For more project info, contact us at our 24 hour answer line at (866) 973-1476 or email mle@sfwater.org
