The benefits of a design and build firm are that you work closely with the architects and the structural engineers of the firm and that firm will then bring that design to realization having full knowledge of the intricacies of the design. The firm will also have the knowledge and experience of coordinating the various build teams and working with the county for obtaining the necessary permits. The firm will also conduct oversight of the project and ensure that the teams are properly building the various components of the plans. Because the same firm is familiar with the plan, they can quickly make adjustments during the project as necessary. Such things as the build of support structures, electrical and plumbing systems, and many other components of the structure are closely scrutinized by the build firm to ensure that they are up to code and are effectively built. The build firm will also extend a warranty in the event that the owner experiences any problems with the built structure(s).
