Omnitrans, Methane and Hydrogen Detection Replacement

Project overview.

The East Valley and West Valley detection-system replacement project upgrades hazardous-gas monitoring and alarm systems serving Omnitrans’ transit maintenance facilities in San Bernardino and Montclair. The work coordinates methane, hydrogen and carbon monoxide detection with ventilation and exhaust interlocks, alarm annunciation, electrical shunt trips, fire-system interfaces and backup power, together with duct-shaft, roofing and interior-finish work at East Valley.

S Y Lee’s construction management scope covers owner and contractor coordination, RFI and submittal tracking, and technical coordination of detector locations, controls interfaces and electrical capacity. The scope also includes requested field observations, schedule and change review, and coordination of system testing, owner training and closeout documentation to support installation within active maintenance facilities.
