Which project delivery method is commonly used in interiors?

• A. Integrated project delivery
• B. Construction management at risk
• C. Design-build
• D. Design-bid-build

Answer: (D)

In interiors, how the project is organized and who is responsible for what matters for budget control and design intent. Design-bid-build is the traditional path: the interior designer completes the design and specifications first, then contractors bid to implement that design. This sequencing lets the designer lock in finishes, materials, and details before any construction starts, so the look and function are clear and the owner can compare transparent bids for the actual build. The separation also provides clear accountability—design decisions rest with the designer, while the builder is chosen through competitive bidding to execute those plans.

Other methods bring more collaboration early on or merge design and construction under one contract, which can be advantageous for fast schedules or highly integrated teams, but they’re less common for standard interior fit-outs where a straightforward, cost-competitive process with a finalized design first is preferred.
