Day 4 of National Construction Appreciation Week!
Today, we’re recognizing our Utilities Teams!
Much of their work happens below the surface, but its impact can be seen throughout our communities. From installing and maintaining underground infrastructure to preparing sites for what comes next, our utility crews keep the work moving from the ground up.
We appreciate the crews doing the work you don’t always see but couldn’t build without!

Day 2 of National Construction Appreciation Week!
Today, we’re recognizing our Dirt Work & Excavation Crews!
Before you can build up, you have to dig down. From excavation and grading to moving and preparing the earth, these crews help create the groundwork for everything that follows.
It takes a lot of hard work to move mountains, and we appreciate the crews who keep our projects moving forward!

It’s National Construction Appreciation Week!
We’re kicking off the week by recognizing our Milling Team!
Milling is often the first step in giving an existing roadway a fresh start. Our crews remove old pavement, prepare the surface, and get the road ready for what comes next.
It’s hard work that lays the foundation for a job well done, and we appreciate the crews who make it happen!
Stay tuned as we highlight another Flanigan division each day this week.
