SPEC WRITER NOTE: VA Medical Facility Construction Safety Committee Chair designates who will complete VHA Pre-Construction Risk Assessments (PCRA) for each construction, renovation, or maintenance project. Project or construction activity scope and complexity determine the need for multiple VHA-PCRAs. VHA-PCRAs are to be completed and documented in accordance with Directive 7715. The VHA-PCRA form must be used to assess and document all construction-associated hazards that affect VA medical facilities, their occupants, services and mission-essential functions and capabilities.

VHA-PCRAs are intended to eliminate or minimize construction- associated risks. The VHA-PCRA form, use instructions and other guidance are available at http://vaww.hefp.va.gov/resources/vha-pre- construction-risk-assessment-pcra. NOTE: This is an internal VA website that is not available to the public.

PRE-CONSTRUCTION RISK ASSESSMENT

Control of all construction-associated hazards that affect VA medical facilities, their occupants, services and mission-essential functions and capabilities is critical in all medical center facilities. JAHVH Pre-Construction Risk Assessments (PCRAs) for construction, renovation and maintenance projects are included with this contract solicitation with required mitigations of identified hazards. JAHVH-PCRAs will be re-validated and updated as needed based on but not limited to changes from original designs, affected individuals, areas/locations, scope, contractor means and methods, safety requirements, phasing, contractor competencies and capabilities.

SPEC WRITER NOTE: Based upon construction activities where the initial infection control review within the VHA-PCRAs identifies potential risks of infectious disease transmission affecting the care, treatment or services of patients or residents include this paragraph. A detailed analysis must be conducted using the VHA-Infection Control Risk Assessment for Construction, Renovation and Maintenance form to document in-depth infection risk assessments and identification of mitigation actions/activities. The VHA-ICRA form use instructions and other guidance are available at: http://vaww.hefp.va.gov/resources/vha- infection-control-risk-assessment-icra. NOTE: This is an internal VA website that is not available to the public.

Infection Prevention and Control is critical in all medical center facilities. Interior construction activities causing disturbance of existing dust, or creating new dust, must be conducted within ventilation-controlled areas that minimize the flow of airborne particles into patient areas. A detailed analysis of potential risks for infectious disease transmission affecting the care, treatment or services of patients or residents has been conducted. JAHVH Infection Control Risk Assessments (ICRAs) are included with this contract solicitation with required mitigation actions/activities. JAHVH ICRAs will be re-validated and updated as needed based on changes in original designs, affected individuals, area(s) or location(s), scope, contractor means and methods, infection prevention and control requirements, differing site conditions, phasing, contractor competencies and capabilities, and infectious disease outbreaks.

For work occurring at a VA medical facility, coordinate with the facility Safety Manager/Officer and Infection Prevention & Control, as several aspects of this section directly relate to infection control risk assessments required in or adjacent to construction affecting occupied and unoccupied buildings accredited by The Joint Commission.
