SCOPE OF WORK

Background:

The National Park Service (NPS) owns and operates the heliport at 1901 Anacostia Drive SE, Washington, DC, which houses the United States Park Police (USPP) Aviation Unit. This facility provides critical emergency and life-support services for NPS, USPP, and other agencies. It is the only USPP facility capable of delivering this function.

The heliport includes two hangars with large bi-fold doors that must always remain fully operational to ensure rapid deployment of helicopters. These doors require routine preventative maintenance to avoid mechanical failures that could impede emergency response capabilities. Given the doors' size and the mission-critical nature of their function, this maintenance work is specialized and must be conducted by a contractor with the appropriate expertise, experience, and equipment.

The services include, but are not limited to, the following:

• Quarterly Preventative Maintenance:

Perform scheduled preventative maintenance on both bi-fold hangar doors and all associated components. This includes inspection, testing, lubrication, adjustment, and servicing of:

o Cables and pulleys o Motors and drive mechanisms o Locking and safety mechanisms o Electrical controls and limit switches o Hinges, panels, and structural components

• Repair Estimates:

Provide detailed cost estimates for any repairs or major adjustments needed to address deficiencies identified during preventative maintenance. Estimates must include labor, parts, and any applicable lead times.

• Emergency Repair Services:

Provide 24-hour on-call support for emergency repairs to ensure hangar door operability. The contractor must respond promptly to service calls to minimize downtime and ensure uninterrupted mission readiness.
