Lesson 4:Public Buildings and Design Process

Design Development

Based on an approved Schematic Design, Design Development is the process of refining and fixing the design, and working out all the details, including the selection of materials and the engineering systems. The aim is to finalize all design decisions before proceeding with Construction Documents, the more detailed and expensive documents that the contractor will need to complete the project. A more detailed cost estimate may also be provided at this phase. In smaller projects, Design Development may become part of the Schematic and Construction Document phases, rather than being a distinct phase of its own. The Design Development package will be reviewed with the client before proceeding further with the project.

  • Finalize construction techniques and materials.
  • Finalize equipment requirements, sizes, furniture layout.
  • Finalize all design issues that affect the look of the building and the feel of the rooms.
  • Choose finish materials.
  • Finalize code issues.
  • Complete outline specifications, a written list of criteria for materials and building methods.
  • Revise cost estimate, considering probable labor and material requirements.
