CLEANING AND/OR MOLD REMEDIATION AND INTERIOR RESTORATION –

RESIDENTIAL UNITS

CRATER LAKE NATIONAL PARK

PROJECT SPECIFICATIONS

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.

1.1.1 Approximate Unit Dimensions:

• Unit 31: 25' x 15' x 8' (2 stories)

• Unit 34A: 25' x 18' x 8' (1 story)

• Unit 34B: 25' x 18' x 8' (1 story)

• Unit 34C: 25' x 18' x 8' (1 story)

• Unit 24: 25' x 18' x 8' (2 stories)

• Unit 28: 25' x 18' x 8' (2 stories)

• Unit 32: 25' x 18' x 8' (2 stories)

Dimensions are approximate and provided for quoting reference only. Quoters are responsible for field verification of actual conditions in accordance with Item 6. Detailed floor plans for each unit are provided in Attachment 06.

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 Specifications, Cleaning and/or Mold Remediation, Crater Lake National Park

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 materials, including ceiling, walls, drywall, plaster, and insulation.

Work areas shall be field-verified and may occur in any room within the unit.

• Interior HEPA vacuuming (per unit): Perform two-pass HEPA vacuuming of all ceilings, walls, floors, furnishings, and contents, including an initial (pre-treatment) cleaning and a secondary (post-antimicrobial application) cleaning, in accordance with IICRC S520 and S100.

• Cleaning, shampooing, and sanitizing (per unit):

o All carpeted areas shall be shampooed and sanitized using HEPA extraction equipment o All hard surfaces shall be cleaned and treated with EPA-registered antimicrobial agents, applied in strict accordance with manufacturer’s instructions, including required dwell/contact time to ensure effectiveness o All furniture and contents shall be cleaned and sanitized, with antimicrobial products applied per manufacturer-specified dwell times.

All furnishings (beds, couches, tables, etc.) must be cleaned and moved as needed to facilitate cleaning and/or repairs by the Contractor. Cleaning of furnishings includes wiping hard surfaces and shampooing, vacuuming, and drying soft furnishings. Furniture replacement is not included in this scope; damaged furnishings identified during pre-work inspection shall be documented and reported to the COR.

Furniture count totals are identified in: Stone Housing Furniture Count Totals (at the end of this document).

• Air purification (per unit): Provide and operate HEPA air scrubbers achieving a minimum of 4 air changes per hour (ACH) per unit in accordance with ASHRAE 52.2.

• Moisture control (per unit): Deploy dehumidification equipment to maintain relative humidity below 60%. Contractor shall maintain daily moisture logs per unit, including ambient temperature, relative humidity, and material moisture readings using calibrated hygrometers and/or moisture meters in accordance with ASTM F2170 or equivalent standards. All instruments shall be calibrated per manufacturer’s requirements and logs shall be submitted as part of project documentation.

• Restoration (per unit): Restoration work shall be performed on a room-by-room basis within each unit, based on identified damage.

Park Service (NPS) preservation standards and guidelines, where historic finishes are present

• Testing and reporting (per unit): Conduct air and surface testing and document results.

The Contractor shall collect and document outdoor baseline samples concurrently with interior testing at each unit. Acceptable conditions shall be defined as indoor air spore counts and surface sampling results that are equal to or lower than outdoor baseline levels, with no dominance of indicator species (e.g., Stachybotrys, Chaetomium, or Aspergillus/Penicillium) and no visible mold growth or musty odors present. All testing results shall be documented and compared against baseline or control samples to establish clearance and avoid ambiguity at project closeout.

• Extent of contamination

ITEM 6 – SITE VERIFICATION RESPONSIBILITY

6.1 All quoters are responsible for field verifying site conditions prior to quote submission. This is a firm-fixed-price type contract; no price adjustments will be made for conditions that were known or discoverable at the time of quoting. Quoters shall assume that for the three (3) units (units 24, 28, and 32) that require both cleaning and repair activities, assume each affected unit includes up to 65 sq ft of selective demolition, which may occur in any room within the unit.

6.2 Hidden or unforeseen conditions will be handled under the procedures of the clause 52.236- 2, Differing Site Conditions.

6.3 Demolition Quantity Basis and Site Investigation:

The 65 square foot per-unit demolition quantity identified in Item 1.3 and Part 3, Phase 2, represents the Government's estimate of water-damaged ceiling, wall, drywall, plaster, and insulation materials that are reasonably observable during a non-destructive walkthrough. This quantity forms the fixed-price basis for units 24, 28, and 32 and shall not be interpreted as a hard cap. Quoters are strongly encouraged, though not required, to attend the scheduled site visit and to inspect all rooms and standard ceiling entry points to verify this assumption prior to submitting a quote. Any discrepancies noted during site investigation shall be brought to the Contracting Officer's attention in writing before quote submission.

Conditions that are unexpected, unforeseen, or hidden at the time of quoting, and that could not reasonably have been discovered through a non-destructive site investigation, will be handled in accordance with FAR 52.236-2, Differing Site Conditions, and FAR 52.236-3, Site Investigation and Conditions Affecting the Work. The Contractor shall notify the Contracting Officer promptly and in writing upon discovery of any such condition before proceeding with work in the affected area.
