The intended purpose of construction scheduling is to assist with proper planning and coordination of a project. All too frequently, construction schedules are used primarily to help build or defend against claims. Much of the process of building claims through the use of schedules involves schedule gamesmanship. This paper briefly identifies 19 common schedule games played on construction projects. The paper also offers 53 suggested defenses to help prevent and detect schedule gamesmanship. Some suggested defenses involve changes to contract document language and thus, need to be implemented during the design phase. Other suggested defenses are pragmatic in nature and can be implemented on a daily basis by a knowledgeable project management team even in the absence of specification language. Additionally, in this new edition of the paper, there is a checklist of 57 items that should be examined when reviewing a schedule to determine whether schedule gamesmanship is being employed.
