Design Development: The first priority of this phase is to define and develop all the important aspects of the project and produce a set of drawings and outline specification to show potential contractors for preliminary cost estimating. If adjustments are necessary to bring the project scope in line with the construction budget, it is best to do this sooner than later. Once we know we are on track, we will talk more specifically about the interior and exterior materials and functionality. By the end of the Design Development phase, the building exterior will be more fully designed, the interior layout completed, dimensions of all spaces finalized, and most materials selected. Consultants with expertise in structural, mechanical, plumbing, electrical systems and others as needed depending on the complexity and scope of the project will be brought on. The deliverable will be a more detailed set of drawings that communicates the overall layout and volume of the building or space, all significant equipment, and the type of material or finish for every surface of the project.
