Addendum 1

This opportunity involves the renovation of two park cabins (Cabin #7 and Cabin #10) located at 46454 Park Chalet Place and 46442 Park Chalet Place in Sterling, Virginia. The scope includes structural deck work (infill only), installation of new 200‑amp electrical panels, exterior‑wall insulation, bathroom ceiling replacement, interior shiplap wall finishes, and various bathroom and window/door upgrades. Several items (e.g., shower pan, vanity selections, window/door specifications) are TBD and will be supplied or clarified by the agency. The project is slated to start on January 1 2027 with a 90‑day completion window, subject to board approval in late November 2026. • Deck infill: removal of existing hot‑tub, new framing, pressure‑treated decking and railing only for the infill portion. • Electrical: new 200‑amp panels for each cabin, with utility‑side work to be coordinated by the MEP engineer. • Interior finishes: vertical shiplap walls throughout, new exterior‑wall insulation, full bathroom ceiling rebuild, and bathroom fixtures (vanities, glass enclosure) as per finish schedule. • Windows/doors: casement window W2 (2′ × 3′ 6″) with safety glazing; door D8 size to be field‑verified before ordering. • Additional considerations: verification of wood‑stove chimney conditions, hazardous‑material survey responsibilities to be clarified later.
