Employer and Employee Responsibilities

Controlling Employers

The employer that is a prime contractor, general contractor, construction manager or any other legal entity which has the overall responsibility for the construction of the project (its planning, quality and completion) is considered the controlling employer, sometimes called the controlling entity.

Controlling employer
The controlling entity establishes a system to coordinate the operations of two cranes that operate within each other's working radius.

Controlling Employer/Entity Responsibilities

The controlling employer/entity has the following responsibilities:

  • seeing that the ground conditions are adequate to support the equipment.
  • informing the user and the operator of the equipment of the location of hazards beneath the equipment set-up area (such as voids, tanks, utilities) if those hazards are identified in documents (such as site drawings, as-built drawings, and soil analyses) in the possession of the controlling entity (whether at the site or off-site) or of any other hazards known to the controlling entity.
  • establishing a system to coordinate the operations of two cranes that operate within each other's working radius.

Responsibility of the Company Operating the Crane

Although the controlling entity is responsible for providing adequate ground conditions, the company operating the crane will often be better able than the controlling entity to determine whether those conditions are adequate. If you are operating a crane and decide that ground conditions are inadequate, you must discuss the problem with the controlling entity and see that the problem is corrected before beginning or continuing operations.
