Manning Design + Construction has over 40 years of construction industry experience in commercial, industrial and residential building projects. We specialize in upgrading buildings to meet changing needs; our goal is to help bring new life to existing structures. Experienced in all phases of the design/build process, we self-perform as much of the project as possible to control quality and budget.

With our role being the installer and maintainer of so many roofs we have designed ourselves, or with our associated design professional partners, we have figured out what works. These nuts and bolts solutions have created in Oregon over 150 sucessful rooftops, as greenzones or living space. In addition to those reinvented rooftops, our commitment to stormwater issues in general, and our work on older buildings performing seismic retrofitting is our contribution to a safer, more sustainable infrastructure.
