Final answer:
The scenario described is an example of the Design-Build delivery method. Hence the correct answer is option 3
Step-by-step explanation:
The scenario described in the question is an example of the Design-Build delivery method. In the Design-Build approach, the owner and architect collaborate with a contractor from the beginning of the design process.
The contractor provides cost estimation and technical advice during the design development stage and then continues to execute the construction once the design is completed. This integrated approach can help streamline the process and improve communication between the different parties involved.
Hence the correct answer is option 3
