• The contractor must exercise care and caution in all activities performed on or near historic structures, landscapes, and other NPS properties. Measures must be taken to protect the landscape and surrounding areas from damage during the execution of the work, ensuring that no harm comes to the landscapes, sites, or park structures throughout the project.

• Contractor is to stop work and alert the park’s contracting officer representative (COR) or other authorized management representatives of any accidental damage immediately so that it can be documented and handled according to proper NPS procedure.

• Contractor will be held responsible for all restoration of the site, both landscape and building, if damaged while work is performed. The restoration must bring the worksite to the appearance and condition that existed prior to the work being performed. The contractor is responsible for cleanup, removal, and disposal of any debris associated with their installation of equipment and restoration of the building if damaged.

• All planned service interruptions must be coordinated with the park, and the time-of-service interruption must be as short as possible. The park shall be notified of any scheduled utility or access interruptions as early as possible, but no less than 48 hours prior to any planned interruption. The contractor is expected to inform the government as soon as it is known that there may be an unplanned interruption.
