1. PROJECT DESCRIPTION / SUMMARY:

The work of this contract is to replace the ADA opening/closing mechanisms for ground floor historic entry doors. There are four sets of double doors at approximately 5’(W) x 7’1.5” (H) rough opening serving as entrance door on the ground floor of the building.

The building is the Yellowstone National Park, National Park Service (NPS) headquarters building located within the boundaries of Fort Yellowstone National Historic Landmark District, Mammoth Hot Springs, Wyoming. It was constructed in 1909 and is considered an important historic building within the Fort. Each door was rehabilitated as part of a whole building rehabilitation project in 2004.

Currently, the historic wood doors on the ground floor have an automatic mechanism that is activated by a card/keypad. Each of the doors has an ABA-accessible automatic door opener pad to provide hands-free entrance/exit. The doors frequently malfunction, resulting in many staff hours to repair them. They do not open and close easily and sometimes do not close completely, allowing cold air into the building and leaving the building unsecured. The NPS has determined that the four sets of double doors need automatic ABA compliant opener.

The lower level four double doors shall be equipped with automatic opening and closing assemblies that comply with Architectural Barriers Act (ABA) and ANSI. Standard ANSI/BHMA A156.19-2019 applies to swing door operators. The operator type will be low energy power operators, for pedestrian use. The activation of all doors described in this standard requires a knowing act. Included are provisions intended to reduce the chance of user injury or entrapment. (ANSI/BHMA A156.19 for Low Energy Power Operated Doors).

A156.19 - 2019 Power Assist and Low Energy Power Operated Doors (buildershardware.com) All doors act as the outside entries into a secure federal government office building and require government issued identification and passcodes to enter. The entire building needs to remain secure during this project. If doors are not operable or not attended at any time during the project work, they shall be secured shut and not accessible. If the doors need to be removed the openings shall be secured at all times.

The government can provide existing as-built drawings and specifications from the 2004 Building Rehabilitation project upon request, which included existing locking mechanisms, and automatic opener/closers installed in 2004/2005. The Government is currently repairing and rebuilding these doors as well as the frames and casing around them in order to re-plumb the doors and make them seal better. The 2004 Building Rehabilitation project locking mechanisms mentioned in this SOW will be replaced as part of our current 2022/2023 repair project with Folger Adam 310-4-1-12D Electric Strike locking mechanisms mounted in the horizontal framing above where the double doors meet. New Opener/closers installed must not interfere with the function and operation of the Folger Adam 310-4-1-12D Electric Strikes.

All mechanisms installed shall be backed by a warranty for a minimum of 2 years. The warranty shall cover parts and labor for standard wear and tear.

Specifically, this scope of work includes the following tasks. For the four sets of entrance doors on the ground floor:

1.1. Replace Door Openers/Closers: Replace the opening and closing hardware with appropriate equipment and mechanisms compatible with the wood doors and their long-term use. This will include door opener/closer. Due to the historic nature of the doors and the limited width available both doors shall function simultaneously. (Dual opener or double door opener). Door opener/ closer shall be motor closed (spring activated is unacceptable)

1.2. Upgraded Openers: The door opener/ closer shall be designed for historic doors to include considerations for weight, door thickness, and the doors overall size.

1.3. ABA operator: The ABA activation push button on the outside of the building shall be wireless RF (Radio Frequency) transmitted , the ABA activation push button on the inside of the building shall be hard wired. The delay entry timer shall be an, Halman MC-25 (10MC25)-time delay or equal to ensure the Park maintains a consistency with other ABA door requirements. The outside keypad entry shall be equipped with an access code approval delay to access building entry, no delay is required from the inside exit push button. The awarded contractor shall coordinate with NPS staff onsite to integrate the door open controls (time delay module) with the existing NPS owned access control system. This task shall be duplicated at all four door locations.

1.4. The ABA compliant opening and closing doors actuators shall be on demand only. When the doors are not operated by the ABA automatic opener, they shall have the ability to unlock and be opened manually and shall close immediately using the motor closure. The National Park Service strives to reduce energy use and improve building efficiencies.

1.5. Testing: Contractor shall ensure that all doors function smoothly, robustly, and with high durability for the long term, while maintaining the historic character of each of the doors.

1.6. Instruction for NPS staff - manuals: Provide product manual(s) for maintaining the automatic openers/closers.

1.7. Instruction to NPS staff – training: Provide a minimum of one training session for Yellowstone National Park staff on the maintenance and care for new equipment. This shall include on site review of typical trouble shooting and maintenance needs as well as any unique challenges noticed pertaining to this project.

1.8. Coordination with door restoration and replacement: These historic doors will be repaired, weatherized, and re-hung on new hinges by the government prior to the installation of new opening and closing mechanisms. The awarded contractor shall communicate all modifications to doors including casing. If modifications are required, they shall communicate with the Park Service Contracting Officer Representative (COR).

1.8.1. The contractor will conduct an initial site meeting with NPS staff to discuss any issues and concerns that pertain to the new opening and closing mechanisms.

1.8.2. The contractor’s schedule will show work on one set of doors at a time in order to allow reasonable access, emergency egress to the building and maximize security.

2. SPECIFIC WORK / TASKS:

2.1. Automatic Door Openers: Four double door locations shall have automatic opening and closing ability that meets ANSI and ABA standards. The mechanisms must be UL and cUL listed.
