STATEMENT OF WORK

1.0 TITLE Boiler Plant Safety Device Testing

2.0 BACKGROUND

Boiler plant safety, reliability, efficiency, and equipment longevity are paramount concerns of Veterans Affairs Medical Center (VAMC) management. Boilers are extremely dangerous if not maintained properly. Malfunctioning burners or controls can cause catastrophic events resulting in injuries and death as well as massive property damage. Regular inspections, testing and calibration by expert technicians are an essential part of a program to address these concerns.
