PART 1 – GENERAL

ITEM 1 – DESCRIPTION OF WORK

1.1 Unit Overview and Service Requirements:

Crater Lake National Park maintains several historic stone residential buildings. These include six (6) two-story, two-bedroom houses and one (1) two-story structure that contains three (3) two-bedroom units. Collectively, these buildings comprise a total of nine (9) residential units.

Of the nine available units, Crater Lake National Park requires cleaning and/or restoration services for seven (7) specific residential units: units 24, 28, 31, 32, and (within Building 34) units 34A, 34B, and 34C. Unit numbering and locations shall be verified against site map included at the end of this document.

1.2 Scope of Work by Unit Type:

Three (3) of the units – units 24, 28, and 32 – require both cleaning and repair activities.

Water intrusion has resulted in microbial growth affecting ceilings, wall finishes, flooring systems, furnishings, and interior air quality in these units. They require mold cleaning, sanitation, and interior restoration services including demolition and restoration of affected drywall and plaster surfaces to address any identified damage.

The remaining four (4) units – specifically, units 31, 34A, 34B, and 34C – require cleaning only. These units do not show any evidence of water damage or mold at present. They will receive cleaning services exclusively, unless further inspection during execution uncovers damage that necessitates additional intervention.

This project establishes a unit-based remediation and restoration scope, where all work is defined and executed on a per unit basis, with total quantities derived from seven (7) units. Work may occur in any room within each unit where damage or contamination is present.

1.3 Work Covered by the Contract Documents:

Project Location:

Crater Lake National Park Scope Summary (PER UNIT BASIS):

All work shall be performed per individual unit as required. Cleaning (and mold remediation and restoration activities, when required) shall be performed throughout the entirety of each unit, including all accessible enclosed spaces such as closets, cabinets, crawlspaces, and similar areas, while demolition and restoration work may occur in any room (living rooms, bedrooms, hallways, or other interior spaces) as required based on field conditions:

• Selective demolition (per unit): Removal and disposal of approximately 65 square feet of water-damaged ceiling materials, including drywall, plaster, and insulation. Work areas shall be field-verified and may occur in any room within the unit.
