TVHS VAMC Air Handler Units Refurbishment

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the solicitation for refurbishing Air Handling Units (AHUs).

• Superintendent Roles: The Superintendent must be on-site at all times. While dual roles (e.g., Superintendent also performing Quality Control) are permissible, the government reserves the right to request a dedicated SSHO if the superintendent fails in SSHO tasks. The prime contractor must provide the Superintendent.
• Roof Certification: A Licensed Engineer stamped certification confirming the roof's support for temporary HVAC equipment is required. The HVAC Subcontractor can provide this if they engage a licensed structural engineer. However, if no temporary roof-mounted HVAC is needed, this specific certification may not be required (this is considered "means and methods" and requires further discussion).
• Missing Attachments: The "Refurbish Air Handling Units Abridged Specifications" and "Specifications - AHU Refurb - Nash Eng." were missing but have been attached via amendment. The bid due date has been extended.
• Drawings/As-Builts: Existing structural drawings, roof load capacity documentation, previous assessments, and equipment layout drawings for Fan Room 15 are not available. Similarly, as-builts for AHUs 4, 24, 39, 40, and 41 are not available; contractors must verify dimensions on-site.
• Siemens BAS Integration: Contractors must use a VA-approved Siemens vendor for integration. Siemens should provide point lists and control drawings; the existing sequence of operation will be used. Contractors need to contact Siemens for startup.
• Temporary HVAC: Full normal service must be maintained by temporary HVAC systems during outages. Routing of temporary ductwork is considered "means and methods," but existing access must be maintained.
• Buy American Act: Waivers are not currently planned. Spare and replacement parts for foreign equipment without domestic availability are exempt.
• Submittals: Procore or similar platforms are acceptable for submittals, but emailing is not. Submittals must track pending and approved items.
• Infection Control (ICRA): Modular walls (like STARC) are allowed for ICRA. Floor and ceiling protection is required.
• Pipe Insulation: VA Master Specification 23 07 11 applies, with specific material and thickness requirements detailed for chilled water, hot water, and condensate lines. Materials must meet ASTM E84 standards.
• UV Lighting: Systems must comply with VA Master Specification 23 40 00, operate in the UV-C germicidal range (254 nm), be UL-listed, and include safety features. Acceptable manufacturers include UV Resources, Steril-Aire, Fresh-Aire UV, or equal.
• Test and Balance (TAB): Specialists must be AABC members or NEBB-certified. The VA must be present during TAB, which requires one week's advance notice.

Several attachments have been provided via amendment, and the bid due date has been extended. Clarifications address key requirements for staffing, technical specifications, and documentation.

• Infection Control Risk Assessment (ICRA): Indicates whether an ICRA is required (Yes/No) and includes signature lines for Infection Prevention and Control, Project Manager, Safety Officer, and Construction Safety Committee.

While this is a permit and not a solicitation, it provides critical information about the safety and procedural requirements that will be enforced for the work. Bidders should note the activity type and the associated control measures, as these will impact how the work is performed and may need to be factored into project planning and cost proposals. The requirement for a contractor-provided safety plan, task hazard analysis, and hazard communication is also relevant.

Other / Unclassified

This document is a VHA Infection Control Risk Assessment (ICRA) template for construction, renovation, and maintenance activities. It outlines procedures for assessing and categorizing activities based on potential infection risks to patients. The template guides users through identifying activity categories, affected areas, patient risk levels, and determining the necessary infection prevention and control precautions (Levels I-IV).

It includes detailed tables for:

• Activity Categories (A-D)
• Affected Area Assessment
• Patient Risk Categories (Low, Medium, High, Highest)
• Level of Infection Prevention and Control Precautions
• Required Infection Prevention and Control Measures for each precaution level
• Minimum measures required upon completion of the activity

A permit form is also included for Level III and IV activities, requiring specific control measures to be posted at the project site.

This document is crucial for any contractor performing construction, renovation, or maintenance work within VHA facilities, particularly in areas that may impact patient care. It establishes the minimum infection control standards and precautions that must be implemented to protect patients and staff. Bidders should review this document to understand the stringent infection control requirements, potential costs associated with compliance (e.g., containment barriers, negative air pressure, specialized cleaning), and how these requirements might affect project timelines and execution. The specific "Activity Category" and "Patient Risk Category" determined for the "AHU Refurbish Fan Room 15" project will dictate the level of precautions and associated control measures required, impacting the scope of work and safety protocols.

This document is an Interim Life Safety Measures (ILSM) Check Sheet for the AHU Refurbish Fan Room project. It is designed to be completed by the Contracting Officer's Representative (COTR) before the project starts and used to ensure that necessary life safety measures are in place during construction.

• The check sheet outlines 8 key questions related to potential construction impacts on life safety, including:
  • Obstruction of exits and provision of alternative arrangements.
  • Access for emergency services.
  • Impairment of fire alarm, detection, or suppression systems and the need for temporary, equivalent systems.
  • Requirements for temporary construction partitions (smoke-tight, non-combustible).
  • Need for additional fire fighting equipment and contractor training.
  • Potential reduction in fire safety levels due to construction and the need for fire drills.
  • Compromise of structural or compartmentation features and the need for alternate fire safety procedures.
  • Implementation of ILSM and initiation of a memorandum clarifying these measures.
• Fields for "Date" and "By" are included for tracking completion of training and corrections.
• A checkbox for "Yes/No" is provided for each question.
• A "Memorandum initiated" date of 4/29/2026 is noted.

While primarily an internal checklist for the COTR and Safety Officer, this document highlights critical life safety considerations that will be managed during the AHU Refurbish Fan Room project. Bidders should be aware that adherence to these life safety measures is a prerequisite for project commencement and ongoing operations. The "Remarks" section indicates that "All work will be performed in the fan room inside the actual air handling unit."
