Which construction delivery method is commonly used?

Design-Bid-Build is commonly recognized as one of the traditional and most widely used construction delivery methods. In this approach, the project is divided into three distinct phases: design, bidding, and construction. Initially, the design phase is managed by an architect or designer who creates detailed plans and specifications for the project. Once the designs are complete, the project is put out to bid, allowing various contractors to submit their proposals based on the provided documents. After selecting a contractor, the construction phase begins.

This method is appreciated for its straightforward structure and clear responsibilities among the parties involved. It ensures that the owner has a comprehensive understanding of the project's design before any construction takes place. Furthermore, because the bids are based on finalized drawings, this can lead to more accurate cost estimations.

Other methods mentioned, such as Design-Construct-Manage and Build-Only, are less traditional and might be chosen for specific projects that require a different management approach or faster delivery times. The General Contractor Approach is more of a broad term that can apply to various methods and does not distinctly represent a unique process like Design-Bid-Build does. Thus, the clarity, structure, and historical prevalence of Design-Bid-Build make it the most commonly used construction delivery method
