Coordination for interior design is 10% of what amount?

• A. The interior design base fee
• B. The total project fee
• C. The construction cost estimate
• D. The architectural fee

Answer: (A)

The amount for coordination of interior design is derived from the interior design scope itself. Since coordination tasks are part of the interior design services, their cost is calculated as a portion of the interior design base fee, not of the overall project, the construction cost estimate, or the architectural fee. Therefore, 10% of the interior design base fee is the appropriate way to size that coordination work. The interior design base fee represents the core charge for interior design services, so tying coordination to that base ensures the cost scales with the level of interior design effort.
