Project delivery methods refer to the various approaches used to organize and manage construction projects. Common methods include Design-Bid-Build, where the design and construction phases are separate, and Design-Build, which combines both phases under one contract. Each method has its own advantages and challenges, influencing project timelines, costs, and collaboration. Another popular method is Construction Management at Risk, where a construction manager is involved early in the project to provide input on design and cost estimates. This method aims to minimize risks and enhance communication among stakeholders, ultimately leading to a more efficient project delivery process.
