Customer Testimonials

My company and I have worked with Irvinbilt Constructors and its predecessor, Irvinbilt Company, on many projects in the last thirty years that include small pump stations to multi-million-dollar water treatment plants and wastewater treatment facilities. We have worked with Irvinbilt on design-bid-build projects as well as design-build. It is obvious that Irvinbilt and their employees are always concerned about craftsmanship and work efficiency.
