Where Curiosity Sparks Innovation
At NWPX, innovation is a mindset. We understand that new ideas or process improvements can come from any level of our organization. Our collaborative and accessible culture promotes innovation and recognizes perspectives that come from different skill sets.
To continue improvements in product design and manufacturing, we reach across industries and collaborate with leaders in civil and environmental engineering, fluid dynamics, seismic engineering, and construction management. This helps us consider new perspectives and opportunities.
Fostering a culture of empowerment and rewarding innovation has led to some of the industry’s most exciting concepts, including the development of corrosion-fighting coatings and linings and joints designed to withstand seismic events. With a culture that welcomes curiosity, it’s no wonder our employee tenure far exceeds the industry average.
