Which of the following are common project delivery methods in construction?

The correct choice highlights two widely recognized project delivery methods in the construction industry: Design-Bid-Build and Design-Build.

Design-Bid-Build is a traditional method where the project owner contracts separately with a designer and a builder. This allows for a clear division of responsibilities and is beneficial in terms of giving the owner control over the design process and ultimately selecting a contractor based on bids. It typically involves three distinct phases: design, bidding, and construction, making it a straightforward approach that many owners prefer for its clarity.

On the other hand, Design-Build is an integrated project delivery method where a single entity is responsible for both design and construction. This can enhance collaboration and streamline communication, reducing the time and cost involved in the project. The owner engages one contractual party, which can lead to increased efficiency and reduced risks associated with miscommunication between designers and contractors.

Both methods are common in the industry, leveraging their unique advantages depending on project specifics, which contributes to their selection by contractors and project owners alike.
