Tonight Grandma and Pop Pop came over to babysit the kids so we could go out for a Girls' Night Out. The kids always have fun with their grandparents.

Cold Weather Biking
Tonight we had to clear out the garage temporarily so Mark could come and pick up the kerosene furnace. It was very chilly outside, and the girls discovered that fall is the perfect time to ride their bikes in the garage!

Waterville Fire Department
Today Kate's preschool class went on a field trip to the Waterville Fire Department. Since Mom had such a long day at work yesterday, she got to sleep in today and go along on the field trip.
Mom's Big Day
Yesterday Mom had to drive all the way to the job site in Massachusetts (and back) in order to help with the first heavyweight concrete pour. The bridge is coming along nicely, with 1/2 of one bascule leaf set in place, and the other half sitting on a barge ready to be installed (see the photo below). There are also two heel girders on-site, waiting to be put in place to start the second bascule leaf.
The pour started at 8:00 sharp when the first concrete truck showed up on site. Unlike a typical concrete pour, the trucks were loaded with only water and cement but no coarse or fine aggregate (rock). This is because the heavyweight aggregate would cause the trucks to be too heavy to drive on the city streets.
Instead, the heavyweight aggregate was added on-site. A small crane was used to pick up the bags of rock and load them into this hopper, where a giant spike was waiting to rip them open. It worked great!
This guy's job was to make sure all the rock got into the hopper, and none spilled out the sides.
Then the mixer truck backed under the hopper and all the rock was dumped in, which resulted in a concrete mix of 5 cubic yards per truck (about 35,000 lb of material).
After mixing, the concrete was tested for air content, slump, and unit weight. Since this was the first pour, there were a lot of spectators from Mass Highway (the bridge owner) observing the tests. Everything looked good, so it was off to the pour site!
Each truck had to back carefully up a 1/4-mile long ramp and then discharge the concrete into the counterweight through this long chute. For a big pour like this, there were about ten workers needed at the counterweight--they lined up the truck, operated the chute, controlled the speed of the concrete coming out, and climbed down inside the counterweight to make sure the concrete got into every nook and cranny.
Mom's job through all of this was to monitor the unit weight of each truck, make sure there were no problems with the falsework (the hangers supporting everything), and show the crew exactly where the concrete needed to go inside the counterweight box.
There were 11 trucks, and the pour took about 5 hours. During breaks between trucks, Mom and her boss took the opportunity to climb around on the leaf and check some survey marks.
The drop to the water here is about 80 feet. It's a good thing Mom is not afraid of heights!

Crisp Fall Evening
Today it was clear, cold, and sunny, and the evening was nice and crisp. We won't be able to play outside after dinner much in a few weeks, so tonight we got out to enjoy it while it lasts.
Mama did a little more work on the sledding hill...
Harvest Festival
Yesterday after pumpkin picking we went to the Waterville Harvest Fest, where we ran into Kate's best friend from preschool, Julia, her little brother Benjamin, and their mom Kate.
