Alternate Delivery Methods

The staff at Flagline Engineering have a unique level of experience in Oregon working with many of the popular alternate delivery methods seen in the engineering industry today. In recent years we have completed projects with CM/GC, Design-Build, and Progressive Design-build formats. Our team can help you understand the difference among these formats and support you in choosing the most beneficial method for your specific project. With most of our project involvement continuing through construction, we are able to identify where these alternate methods can save your project time and money as a whole.

Our staff is active in attending the Design-Build Institute of America (DBIA) conferences every year in order to keep apprised with the latest developments in the area of alternate delivery. Our teams are capable of delivering public and private projects ranging from $100K to $500M in total project cost. We currently have several projects in motion throughout Oregon that utilize these methods and we happy to be a part of the growing movement to make these practices standard for both public and private sectors. Collaboration between owners, engineers, and contractors equates to a better product in a shorter schedule.

Feel free to contact our team members any time to see if one of these alternate delivery methods are right for your project. For more information you can also visit
