Construction Meets
Logistics.
Our affiliated Stowers Trucking operation puts owned haul capacity behind every S3 project — so the field never waits on a truck that didn't show up.
- 01
Faster Material Movement
Owned haul capacity dispatched from the same yard as the field crews.
- 02
Less Downtime
Trucks arrive on the schedule we set — not a third party's queue.
- 03
Better Scheduling
One dispatch board for excavation, hauling, and material delivery.
- 04
Improved Project Control
Single point of accountability from cut to fill to off-haul.
- 05
Reduced 3rd-Party Risk
Fewer hand-offs, fewer no-shows, fewer cost surprises.
Trusted On The Jobsite
“S3 ran the dirt, the utilities, and the haul-off as one operation. The schedule held and the site was pave-ready when they said it would be.”
“Honest, responsive, and they show up with the right iron. That's a short list of contractors in this part of the state.”
