Design-Build Services


Design-build transforms an engineer’s design into a constructed environment faster than any other delivery method. The design-build project delivery approach integrates the knowledge, creativity, experience, and passions of the design and construction professionals from the beginning to the end of a project. Constructibility is built into the design from day one and typically projects are in service much sooner than with the traditional design-bid-build project delivery method. DEA’s commitment and passion given to selecting design-build partners and projects has resulted in award-winning projects, satisfied clients, and successful team members.
