1. General Information

1.1 Background and Objective

The Department of the Navy requires professional, specialized biohazard remediation, specialty cleaning, and mechanical HVAC air system cleaning services across two separate facilities at Naval Station Norfolk, Virginia: Building R-50 and Building U-117.

Building R-50 (SGOT-N): This facility is a two-story administrative and logistics support building measuring approximately 13,000 square feet in footprint (over two floors). The area above the drop-ceiling grid has accumulated general dirt, flaking paint from structural components, and biological contamination consisting of rodent (rat) feces, urine, and nesting materials.

Building U-117 (FWC-N): This facility is a single-story administrative and operational support building measuring approximately 30,000 square feet. The area above the drop-ceiling grid has accumulated general dirt and biological contamination consisting of rodent (rat/pest) feces, urine, and nesting materials. A Navy Environmental and Preventive Medicine Unit TWO (NEPMU-2) Technical Assist Visit (TAV) conducted on June 25, 2026, confirmed these biological hazards above the drop-ceiling grid in several administrative offices and hallways. This contract ensures the thorough extraction of biological contaminants, sanitization of above-ceiling spaces, and professional mechanical cleaning and disinfection of the building's air distribution and ventilation equipment.

The objective is to restore a safe, sanitary, and healthy working environment that protects active duty, civilian, and contractor personnel in compliance with Department of Defense (DoD), Department of the Navy (DoN), OSHA, and CDC standards. All work shall comply with DoD, DoN, OSHA, CDC, and EPA standards.

1.2 Scope of Work

The Contractor shall provide all management, supervision, labor, licensed/certified personnel, specialized equipment (including high-powered and certified HEPA-filtered vacuums, negative pressure machines, containment systems, and mechanical duct cleaning tools), Personal Protective Equipment (PPE), sanitizing and antimicrobial agents, tools, containment materials, waste disposal, and transportation necessary to execute this project. The procurement is structured into two distinct task areas based on facility requirements:

Task 1: Building R-50 (SGOT-N) Above-Ceiling Remediation & Specialty Cleaning

Physical containment and HVAC isolation.

Extraction and disposal of rodent droppings, nesting materials, and associated biological contaminants.

Removal and HEPA capture of loose, flaking paint from structural members and decking.

Building U-117 (FWC-N): The Period of Performance shall be IAW designated CLIN.

1.4 Hours of Operation and Scheduling Protocols

Standard Work Hours Preference and Local Command Coordination: Performing work during standard Government working hours (Monday through Friday, 0700 to 1630 hours) is both permitted and preferred. The Contractor shall closely coordinate all weekday work schedules, phasing plans, and access requirements with the technical point of contact (TPOC), Facility Managers, and local command leadership (SGOT-N and FWC-N) to ensure active military operations, watch standing, and administrative functions are minimally disrupted.

Sealed Containment Protocols for Weekday Work: Due to the hazardous nature of biological agents (Hantavirus, rodent urine/feces), flaking lead-safe paint chips, and airborne particulates, working during normal business hours requires that all necessary technical steps are rigorously executed to isolate the active work areas:

The Contractor shall establish fully sealed, negative-pressure containment zones (utilizing minimum 6-mil poly sheeting and critical barriers) prior to disturbing any building components or ceiling grid elements.

All air handling equipment servicing the active zone shall be locked out and isolated to prevent cross-contamination to occupied spaces.

Stringent containment integrity must be maintained not only during active biohazard extraction and duct cleaning, but also throughout the entire demobilization, bag-out, and waste load-out process. Removal of containment sheeting, biohazard waste bags, HEPA equipment, and accumulated dust must be carried out in sealed transition chambers or double-bagged transit routes to guarantee zero contaminant release into corridors, adjacent occupied offices, or HVAC supply paths.

Alternative Weekend Schedule: In the event that weekday work is determined by the Government or Contractor to be non-feasible, unsustainable, or causes unacceptable disruption to mission-critical operations, an alternative weekend execution schedule is fully authorized and acceptable. Weekend shift windows shall be coordinated and approved by the TPOC and Facility Manager as follows:

Building R-50 (SGOT-N): Friday 1400 hours to Sunday 2200 hours.

Building U-117 (FWC-N): Friday 1600 hours to Sunday 2200 hours.

Turnover Requirements: Regardless of whether work is executed during standard working hours or weekend shifts, the Contractor shall ensure that all active workspaces are fully de-contained, cleaned, sanitized, and cleared for occupancy prior to the start of normal business activities each workday morning.
