What must contractors do upon arriving at the work location?

Upon arriving at the work location, contractors must complete a daily sign-in. This process is crucial for maintaining an accurate record of who is present on site, which enhances safety and accountability. The daily sign-in not only helps ensure that all individuals on the job are authorized and properly trained but also aids in emergency planning and response. Keep in mind that maintaining a record of attendance is key for understanding the workforce presence and ensuring compliance with safety regulations.

The other choices, while related to project management and safety practices, do not represent the immediate action required upon arrival. Completing a project proposal or submitting a performance report are actions that typically occur at different stages of the project rather than immediately upon arrival. Conducting a job safety analysis is an important safety practice, but it is typically done prior to starting specific tasks, rather than as a first step upon arriving at the work location. Hence, daily sign-in is the correct procedure to follow at the onset of the workday.
