PL.06 Specify Conditions & Constraints on the Tasks Context Execution of a Task may require, or impose, specific conditions or constraints in the workplace. Some of these may affect the placement of the Task with other a Tasks in a schedule viz the conditions or constraints define the synergies and conflicts that need to be managed in the scheduling process. For example, a condition on a Task may require that a business area be shutdown or operating. Similarly, undertaking some Tasks may restrict access in or around an area e.g. where equipment used in the work will occupy what is normally an access way or, if the work creates a potential hazard then execution may require the constraint that there be no other work taking place at the same time in the immediate area. Note that while a hazard may result in a constraint, in the Planning process conditions and constraints are distinct from potential hazards, their associated risks, and the controls used to manage them. The planning of hazards and controls is dealt with in a separate Task Assignment. In order to successfully schedule Tasks any conditions or constraints that are necessary for work must be specified. While some conditions or constraints may have been identified and recorded at the approval of the work, it is essential that all relevant conditions and constraints be specified during the planning of each Task. Purpose To specify each condition/constraint that must be applied to each Task. Quantity The Task documentation shall as a minimum specify each mandatory condition or constraint. Quality The specification shall include anything that must be;  established prior to the commencement of the work (e.g. areas either shutdown or operating, storage areas full or empty),  maintained during the work (e.g. specific operating conditions or access to the work site),  restricted during the work (e.g. access through/above/below the work site), and  any other condition or constraint that is necessary for the work. If the method of achieving a condition or constraint matters, the Task must also specify the required method.
