The Design-Build method of project delivery involves a single source for design and construction services. While the Design-Build method may be applied to a wide variety of project types and sizes, this guide is generally more suited to large or complex projects. The Series 200 documents are intended to assist Owners in preparing documents for a Design-Build proposal call, however prospective Design-Builders should also make themselves aware of the content of the Series 200 documents to understand the Owner’s perspective. Design-Builders are advised to refer to Series 300 for best practices in responding to RFQs and RFPs.
