STATEMENT OF WORK (SOW)

Window Frames FY26

December 3, 2025

1. General:

1.1 Overview:

Yukon Delta National Wildlife Refuge operates multiple residential structures for employees in Bethel, AK. Our headquarters building is at 807 Chief Eddie Hoffman HWY, Bethel, AK 99559. Our Refuge maintains nine (9) nearly identical two-story houses on pilings. The window frames and matching windowpanes on the top floor of all houses have been identified to be replaced. Bethel is approximately 800 air miles west of Anchorage, Alaska. Bethel has no road access and can only be reached by air or sea. The project sites are accessible by vehicle. We are seeking bids to complete the work described in this Statement of Work.

1.2 Purpose/End Application:

Our Refuge maintains nine (9) nearly identical two-story houses on pilings. The floorplans are the same, just swapped/flipped pending location (see attachment). The windows throughout these quarters are tilt-turn style frames and were manufactured by Alaska Window in Fairbanks.

Unfortunately, that company is out of business now. Many of the window frames are starting to break down over years of use and replacement parts are no longer available. Moisture seepage has caused rust and corrosion on ferrous and non-ferrous surfaces and components of the frames. We are interested in having new window frames and window panes and mechanical fixtures for windows on the top floors of the nine (9) quarters. These new windows frames shall have replaceable window panes and a support market for replacement components and hardware. They will need to be replaced with like window frames and window panes as what is removed (i.e., the same side tilts/turns). Windowsills shall also be replaced on all windows frames from wood to a solid waterproof material such as Corian® or vinyl.

We have strong concerns about how the windows could have been installed originally due to moisture seepage we have observed. Once an old window frame is removed, a thorough inspection of the surrounding flashing and water impermeability layer (vapor barrier) is needed. If any damage is found in the flashing, vapor barrier, or wood framing around the windows, the damage will need to be repaired prior to the installation of the new window frame. In that case, new flashing, vapor barrios, and installation materials will need to be used. These additional costs are will not be in the base bid and will be assessed while on site. It is also worth noting that we wish to maintain the vinyl siding on the houses currently and extra care will be needed when removing and reinstalling window frames not to damage exterior siding. If damage occurs, the contractor shall repair damage caused.

1.3 Contractor Qualifications:

1.3.1 General contractors and specialty subcontractors shall be licensed and well qualified to perform the work consistent with the Contract Documents. We may reasonably object to

Contractor's proposed selection of workers and business entities. We prefer Contractors and Subcontractors that have worked in remote Alaska (e.g., Bethel) so we know they understand logistics and potential complexity with completing contracts here. If damage is found at the window rough openings, additional skilled labor (e.g., licensed

Mechanical Contractor) might be necessary and would be assessed and quoted beyond the original bid.

1.3.2 Provide documentation of current state certification of General Contractors and any additional skilled laborers required to fulfill the contract.

1.4 Other: Structural drawings and photos are attached or included as figures below.

(GFI):

5.1.1 The Contractor shall provide their own tools and hardware. Storage of new window frames will be allowed in in the garages of the houses for the installations as well as a vacant FWS-operated garage at 228 Blackberry

Drive, Bethel, AK 99559. These garages are equipped with a single car bay door for access.

5.1.2 In addition to the Availability and Use of Utility Services clause Federal Acquisition

Regulation (FAR) 52.236-14, the Contractor shall furnish all temporary facilities and utilities needed including: heat, light, power, water, telephone, sanitary facilities, job offices, material handling equipment, temporary construction aids, and storage enclosures. If suitable USFWS water, electric, or other utility is present at the site, it may be used for construction purposes at no cost, only if it does not adversely impact the operations of the station and field station agrees to permit use. The Contractor shall provide and remove any temporary connections required.

5.1.3 It is encouraged that the Contractor participates in a site visit to assess work outlined in the SOW and to identify appropriate tools and hardware prior to work occurring.

5.2 Identify any limitations:

5.2.1 There are several hardware stores in Bethel, AK, though their supply and stock might not be adequate to fulfill the scope of this contract. Contractor is responsible for their tools and all hardware to complete this contract. The contractor will need a ladder to access the exterior of the windows. The refuge will not provide a ladder.

5.2.2 The Contractor will be required to travel to all residences on their own, therefore it is strongly advised that they rent a vehicle. Renting a vehicle might not be necessary due to available taxi services in Bethel. Regardless, no GPE, such as a vehicle or transportation between sites will be available to the Contractor from the Government.

6. Evaluation and Acceptance

6.1 The rough openings of each window need to be inspected by the Lead Maintenance Worker and/or the

Assistant Refuge Manager to assess moisture damage before new window frames are installed. This inspection will be required to assure that any damage is addressed. Any location with moisture damage will need to have the flashing and water barriers pulled back to assess full damage.

6.2 The work shall be done in accordance with all applicable federal, state and local codes including the most current edition of the IBC, National Electrical Code (NEC), NFPA 101 Life Safety Code, ADA/ABA, and any other applicable disciplines of the International Code Council, as well as with accepted general industry standards.

6.3 The work shall be accepted when all the work is completed as described here within and in accordance with any contract documents. Work will be inspected to assure compliance with the contract documents, but quality control and adherence to all contract requirements is the responsibility of the contractor, as further described in CFR 52.246-12, “Inspection of Construction”.

6.4 The Contractor’s work will be evaluated by the Lead Maintenance Worker and/or the Assistant

Refuge Manager. Work shall be completed in a clean and professional manner. Refuse/trash shall be cleaned up after completion of work at each residence. Communication from

Contractor on when work is completed at residences is required for final inspection at each residence and tenant coordination to access the next residence.

7. Quality Assurance/Quality Control (QAQC):

7.1 The Contractor’s work will be evaluated by the COR with the Lead Maintenance Worker and the Assistant Refuge Manager within the POP. Work shall be completed in a clean and professional manner and performed up to code. Refuse/trash shall be cleaned up after completion of work at each residence. If work is found to be faulty beyond the POP the

Contractor shall be held responsible for repairing their mistake, up to returning the site at the cost of the Contractor (see contract language beyond the Scope of Work). Photos, video, and/or clear documentation of failures or mistakes would be provided by the Lead Maintenance

Worker and/or the Assistant Refuge Manager via the Contracting Officer.
