B. General Requirements:

1. Except for shutdowns specified in this Section, perform the Work such that Owner’s facility remains in continuous satisfactory operation during the Project. Schedule and conduct the Work such that the Work does not: impede Owner’s production or processes, create potential hazards to operating equipment and personnel, reduce the quality of the facility’s products or effluent, or cause odors or other nuisances.

2. Work not specifically covered in this Section or in referenced Sections may, in general, be completed at any time during regular working hours in accordance with the General Conditions and Supplementary Conditions, subject to the requirements in this Section.
