What type of log is used to track delays in a construction project?

The correct answer to the question is the Delay Log. A Delay Log specifically serves the purpose of documenting any delays encountered during a construction project. This type of log captures details such as the nature of the delay, the reasons for it, and the impact on the project timeline. By maintaining an accurate Delay Log, project managers can analyze the frequency and causes of delays, enabling them to make informed decisions and adjustments to keep the project on track.

The other logs mentioned, while useful for various aspects of project management, do not specifically focus on tracking delays. A Progress Log typically records the overall advancement of the project, detailing milestones and completion percentages, but does not specifically concentrate on delays. A Submittal Log is used to track the submission and approval of documents needed for the project, helping ensure compliance and facilitate communication, but it does not monitor project delays. Lastly, an Issue Log addresses problems or concerns that arise during the project, including matters needing resolution, but it does not specifically track delays. Each of these logs serves different functions in project management, which highlights the specialized role of the Delay Log in managing construction timelines.
