STATEMENT OF WORK
Contract Title:
IEStechno Exposure System Purchase Contract at VA Pittsburgh Healthcare System (VAPHS).
Background:
The VA Pittsburgh Healthcare System (VAPHS) is in need of an inhalation exposure system to support controlled experimental exposure studies involving aerosolized particulates, vapors, and gaseous agents. The system shall be designed to enable reproducible delivery of defined aerosolized or gaseous exposures to in vivo animal models and in vitro cellular systems under controlled laboratory conditions. This shared research resource will enhance the capability of investigators at VAPHS to conduct translational and preclinical studies related to respiratory health, toxicology, military exposure research, environmental exposure science, and related biomedical research areas.
Scope:
The Contractor shall construct and install a modular inhalation exposure system capable of providing reliable and reproducible exposure conditions suitable for a variety of inhalation research applications, including aerosolized particulates, vapors, and gaseous agents, while supporting appropriate environmental control, monitoring, and safety requirements. The inhalation exposure system shall be capable of supporting both in vivo animal models and in vitro cellular, as required by specific study designs, as well as include integrated controls for airflow, temperature, humidity, aerosol/gas concentration monitoring, and exposure duration. The system shall also incorporate multiple engineering and procedural safety features intended to minimize risk and ensure compliance with institutional safety standards.
Deliverables/Technical Requirements
The inhalation exposure system shall include:

Annual Service Contract (ServQuad): Contractor Requirements:
System Delivery and Installation
The Contractor shall deliver all system components to the designated laboratory site and perform complete installation. Installation shall include assembly, integration of modules, connection to facility utilities as required, and verification of full system functionality and operational readiness.
System Validation and Performance Verification
The Contractor shall perform full system validation, including: functional verification of all system components; calibration of sensors and monitoring devices; validation of aerosol, gas, and vapor generation performance; confirmation of exposure control stability and reproducibility; and demonstration of proper operation of all safety and control systems
Training Requirements
The Contractor shall provide comprehensive on-site training for end users. Training shall include three (3) full days of instruction covering system operation, maintenance, safety procedures, troubleshooting, and data acquisition/analysis. Unlimited remote support (email and telephone) shall also be provided.
Preventative Maintenance and Service Support
The Contractor shall provide an annual service agreement including four (4) scheduled on-site maintenance visits per year. During each visit, preventative maintenance will be performed including filter replacement, sensor calibration, replacement of disposable parts showing wear, and updates/tuning of exposure control systems. Any equipment issues or failures will be identified during these visits; however, the cost of replacing any damaged or non-functional equipment will be the responsibility of the Customer.
Documentation Requirements
The contractor shall provide full system documentation, including operation manuals, maintenance procedures, calibration protocols, and software user guides.
Safety and Compliance
The system shall comply with applicable institutional, occupational, and laboratory safety standards and regulations. The Contractor shall ensure the system is suitable for operation in controlled inhalation exposure research environments involving aerosols, gases, vapors, and other experimental toxicants.
Other Requirements
