1/31/2024 Page 4 of 9

1. The following conditions may be applicable to work sites inside Park boundaries:

a. WEATHER – Sudden and dramatic changes in climate conditions are common. The Contractor must be prepared to alter work plans and provide protection for workers and equipment.

b. CLOSURES – Park officials may close portions of the Park at any time to protect visitors from hazardous conditions or to implement official duties of the Park.

c. REMOTENESS – Many portions of the Park are of some distance to typical services available in developed areas, including cellular, food, fuel, and emergency services.

The Contractor must arrange and account for appropriate precautions and plans prior to bid submission.

d. SITE SECURITY – Much of Park land is accessible by the public 24-hours a day throughout the year. Park law enforcement officers and other staff will not be designated to provide extra security to protect project sites from visitor intrusion. The Contractor will implement necessary pedestrian controls to restrict visitors from accessing the work areas. The Contractor shall take measures to prevent vandalism, theft, or destruction of project materials and equipment. Any proposed security measures that may affect ongoing access or use of areas otherwise not already included in the construction zone (including remote security cameras or alarms) must be approved by the COR prior to use. Any security issues must be reported to the COR immediately upon notice. Park law enforcement staff may request official statements or other information from Contractor personnel needed to follow up on reported issues.

e. RESOURCES – As a unit of the National Park System, the Park is tasked to preserve unimpaired its natural and cultural resources and values. The Contractor must make every effort to ensure no impacts are made deleterious to these resources. It is expected that the project site and access areas will be minimally impacted only as absolutely necessary for the performance of contract requirements. Mitigations approved by the COR will be taken to restore pre-existing conditions.

INVASIVE EXOTICS – To reduce the chance that harmful, non-native plants or organisms will be transported from off-Park locations to the work site, the contractor, prior to entering the Park, must clean all soils, roots, seeds, and other sources of plant parts and pathogens from any equipment used for the application of grasses and all heavy equipment, such as dump trucks, front end loader, and graders, which have previously been operating off the Park.

Very few wildlife species present any danger to persons working within the Park. Even species which have the potential to do harm to persons, can usually be avoided. Unless wildlife is presenting an immediate threat to persons, harassment or destruction of wildlife is prohibited.
