About Us

IIW P.C. is a relationship-driven firm focused on providing more complete solutions with teams of specialists in engineering, architecture and surveying. These professionals are not only delivering the best practices in the industry, but they’re developing them to better meet the needs and goals of our clients. Having one source that can provide a diversity of expertise is rare, but it makes a defining difference.


The work of IIW demonstrates a commitment to delivering responsive, innovative and practical solutions for clients. Every project is different and, at IIW, our team appreciates that diversity and opportunity to problem solve.

That often takes a team. IIW has teams of professionals in engineering specialties such as environmental, municipal, structural, land development and transportation as well as architecture, land surveying and construction services.


Many firms talk about lasting relationships. At IIW, it’s those relationships that have driven our growth to four offices in the upper Midwest with our corporate headquarters in Dubuque, Iowa. We believe in partnering with our clients to provide thoughtful designs that match their needs and goals – not ours.
