In-progress final design is typically how complete?

• A. 60% to 90%
• B. 10% to 30%
• C. 90% to 100%
• D. 30% to 60%

Answer: (A)

During the in-progress final design, the project design has moved beyond the basic concept and schematic work and into a stage where most systems and arrangements are defined and enough detail exists to support pricing, scheduling, and coordination. This typically falls in roughly the 60% to 90% complete range. At this point, major components are selected, layouts and interfaces are coordinated (so trades don’t clash), and critical decisions are being locked in, yet there is still some flexibility to refine details, correct issues, and finalize the construction documents. It’s not early enough to be just 10%–30% or 30%–60% (where design is still taking shape), and not so close to completion that you’re already finalizing construction documents.
