Project delivery methods defines the characteristics of how a construction project is designed and built and the responsibilities of the parties involved in the construction (owner, designer and contractor). [1] They are used by a construction manager who is working as an agent to the owner or by the owner itself to carry-out a construction project while mitigating the risks to the scope of work, time, budget, quality and safety of the project. These risks ranges from cost overruns, time delays and conflict among the various parties.[2]
