Kanaryarmiut Field Main Cabin Demolition Yukon Delta National Wildlife Refuge Bethel, AK 99559

STATEMENT OF WORK

DEMOLITION OF KANARYARMIUT FIELD STATION’S MAIN CABIN

AT

(Yukon Delta National Wildlife Refuge)

PART 1 - GENERAL

1.1 BACKGROUND

The Kanaryarmiut Field Station has been a highly utilized remote field station for the Refuge since the early 1980’s. This field site is located within dense shorebird nesting habitats, within accessible distance to the coast for waterfowl and shorebird studies, had easy access by boat via the river, but was also situated on a large freshwater lake that maintained enough depth so float planes could easily access it (Figure 1).

Planes landed at this lake throughout the summer to deploy camps, re-fuel, and stage gear going to other locations. Typhoon Merbok impacted this region in September of 2022 and flooded the landscape and drastically changed this remote camp location. Flooding inundated the field camp and eroded the embankment that separated the freshwater lake to the northeast of the field station and the tidally influenced Kuyungsik River channel to the west. Once the storm surge began to recede, erosion increased and further channelized a path for surface flow to drain the freshwater lake.

The lake is now influenced by the ebb and flow of the tide and is hydrologically connected the channel to the west. The newly formed channel continues to erode rapidly and all the existing structures at the field camp are at risk of falling into the river. In addition to the risk of asset loss, the lake is no longer suitable for safe and reliable float plane landings. Since the former lake is now subject to the ebb and flow of tide the area does not maintain a constant level, which renders it unsafe and unusable to land on with a float plane. The three Avgas tanks along the lakeshore are no longer usable for refueling, as they are too far from any location a plane can access to be useful and may be in danger of going into the lake with erosion as well (Figures 2-3).

1.2 SCOPE COMPONENTS:

1.2.1 The U.S. Fish & Wildlife Service (USFWS) Yukon Delta National Wildlife Refuge, Bethel, Alaska is requesting a Request For Quote (RFQ) for demolition of the main cabin at the Kanaryarmiut Field Station near Chevak, AK (location descriptions are in Section 3, Figures 4-9). Work related to this proposed contract is in accordance with an Environmental Assessment (USFWS 2024) and Finding of No Significant Impact completed in 2024 related to the Kanaryarmiut Field Station.

1.2.2 A familiarity with organizing logistics for remote Alaskan wilderness locations, especially in wetland tundra habitat is essential for the success of this project.

1.2.3 The cabin will need to be demolished in a manner that reduces flying debris and additional hazards (e.g., broken glass). The method of demolition will be left to the discretion of the contractor, but mechanical tools such as chainsaws and reciprocating saws are likely. There is not a need for individual/clean board removal and large sections can be removed at the same time. Hardware such as nails and screws are to be collected upon removal and contained in boxes or bags for disposal.

1.2.4 Demolition work will be limited to within 30’ of the main cabin itself and/or to boardwalks.

Damage to the Tundra is to be avoided through the duration of the demolition. Work done in the winter months while the ground is frozen is exempt from 30’, while general clutter and refuse should be contained and not expand across the entire field site.

1.2.5 All materials from the cabin can be removed from the side or reusable material such as large pieces of wood, unbroken windows, metal roofing, and hardware are to be stacked on the boardwalks on site for later transport. Individual components/sections should not exceed approximately 100lbs nor be larger than 10’x 4’. This material will likely be given to the public or transported to a landfill by USFWS. Trash, debris, and refuse are to be removed and disposed of in a city landfill that the contractor has received permission for. All material should be contained to avoid said material blowing around on the tundra.

The contractor will have regular discussions with USFWS to identify material that should be left in stacks or brought to the landfill by the contractor.

1.2.6 Contractors are allowed to use the main cabin for overnight stays while demolishing it.

Human waste (e.g., feces, food) are to be removed from the site by the contractor after the completion of each work stint.

1.2.7 The triodetic foundation will also need to be taken apart and placed in a stack on a boardwalk.

1.2.8 Upon completion of the demolition, there should be no materials on the ground/footprint of where the main cabin was. USFWS will either inspect or require pictures of the stacked material to ensure the site is clean and completed.

1.2.9 Bid shall include all labor, materials, travel, and equipment to complete the scope of work.

The bid shall consist of a work plan and proposal including the following:

1.2.9.1 Written detailed list of all materials, labor costs, and logistical support required (aircraft, boat, snowmobile, and/or helicopter)

1.2.9.2 Provide a clear schedule for work to start and be completed and its various stages.

PART 2 - PERIOD & PLACE OF PERFORMANCE

2.1 PERIOD OF PERFORMANCE:

2.1.1 The Contractor shall have until the end of the summer season in 2026 (approximately

9/30/2026) to complete the project.

2.2 LOCATION COORDINATES:

2.2.1 Kanaryarmiut Main Cabin (61.3614013/-165.1279485): This building is approximately 20’ x 46’ for ~920ft2. All dimensions are to be verified by referencing the structural drawing (Figures 10-12). Interior wall surfaces could be around 5,500ft2. This is a remote field location.

2.2.2 The Cabin sits on tundra approximately 100’ from the river. The ground is not level, nor stable. Depending on time of year, the area surrounding the area will be wet. Boardwalks are in place for ease of walking/working and to reduce damage to the tundra.

2.3 TRANSPORTATION:

2.3.1 Transportation to and from the site can be by float plane or by boat from the closest village, Chevak (61.5256208/-165.5871904) in the non-frozen months. Float plane vendors in Bethel, AK (e.g., Papa Bear, Renfros) could be used to travel directly to the site in the late spring, summer, or early fall timeframes. Transportation from Bethel, AK to Chevak, AK would be by commercial air vendors (e.g., Grant Aviation, Ryan Air). Boat rentals from Chevak, AK are unknown, but likely possible. Access to the site in the winter/frozen months could occur on snowmachine. Snowmachine rentals from Chevak are unknown, but likely possible.

2.3.2 Access/travel across non-Refuge lands would require permission from landowners where applicable.

PART 3 - GUIDELINES

3.1 The contractor’s primary contact will be Ed Davis, Assistant Refuge Manager at Yukon Delta NWR, Bethel, AK.

3.2 Communication related to work trips to the site will be required to reduce potential conflict with Refuge users. This will include proposed dates, number of individuals on site, and general updates on work progress. There are research projects that could be occurring in the spring and summer months in the general area. Subsistence users also travel through the area year-round.

3.3 There are many fish camps nearby to the work site. Inquiries directed towards the contractors related to the demolition or requests for materials should be directed to the FWS primary contact Ed Davis. No materials are to be given to anyone for personal use during demolition work by the contractor.
