In design development, the schematic plans and elevations are reviewed, revised and expanded to incorporate all the details and specifications required for construction.
Project components are looked at to the smallest detail. These include:
- Interior and exterior building materials and finishes.
- Furniture and equipment selection and layouts.
- Cabinetry and custom fabrications.
- Lighting and technology designs.
- Mechanical, electrical and plumbing systems.
Issues often come to light that affect constructability or are critical to satisfying the project program, and that may require changes to the project program or to the budget, or both.
By the end of design development the design drawings and specifications are sufficiently complete to establish and define the facility's size, function, configuration and spaces, the operation or use of equipment and the materials for all the principal building structures and systems. With this information, the project budget and schedule and all building plans are finalized.
Specifications: written descriptions, requirements and standards for all building fixtures, components, finishes and materials.
