For which types of designs does the RFP typically account for 10% to 15% of the cost of work?

The statement regarding architectural interiors accounting for 10% to 15% of the cost of work in an RFP (Request for Proposal) context is based on the typical proportions of budget allocation for design projects. Architectural interiors generally require comprehensive design services that address layout, ergonomics, aesthetics, and functionality within interior spaces. This involves not only considerations for furniture, fixtures, and finishes, but also thoughtful design that enhances the user experience and reflects the purpose of the space.

In contrast, while the other options involve significant expertise and specialized skills, they often require different levels of investment regarding budget allocation. For example, architectural lighting layouts and acoustic designs may have unique requirements and associated costs that can vary significantly based on scope and complexity but might not consistently fit within the 10% to 15% range. Similarly, site development planning involves larger-scale considerations such as land use, zoning, and environmental impact, which typically exceed that percentage due to the broader scope of work involved.

Thus, architectural interiors align more closely with the typical budget percentage allocated in the RFP context, reflecting the balance between design complexity and project costs.
