Knife River Prestress, a leading producer of structural precast in the Pacific Northwest, wants to share how the precast prestressed bridges of the region are made.
Knife River received a call from a new electric car dealership that needed a precast roof system, as their steel roof joists were 10-12 months out. A week later, we had flipped the building to a total precast system, and after 24 weeks, we had finished the installation. We build with the efficiency of precast.
