Attachment A - Transformer list_Rev 2.xlsx

This is an attachment listing that specifies the transformer inventory and required oil analysis services for a federal contract opportunity at the NIST Gaithersburg, Maryland facility. The document details 121 transformers across multiple buildings and locations, with equipment specifications including KVA ratings (ranging from 300 to 7,500 KVA), fluid types (primarily SIL, FR3, Biotemp, and retrofilled varieties), and capacity measurements in gallons. Each transformer requires three types of service: Oil Quality analysis (121 samples across all periods), PCB analyses (33 samples), and Dissolved Gas Analysis or DGA (121 samples). The transformer list is identical across the base year and all four option years, with consistent service requirements maintained throughout the contract period.

The attachment indicates that two transformers (Building 420 and Building 103) have information to be provided at a later date. Transformers are distributed across numerous buildings and yard locations, with specific equipment identifiers, manufacturer information, and serial numbers documented for tracking and maintenance purposes. The contract scope encompasses visual inspection and oil sampling services in addition to the analytical testing specified in this attachment. This standardized, recurring service requirement across five contract years (one base year plus four option years) establishes a predictable scope for transformer condition monitoring and risk mitigation related to arc flash, component failure, structural fire, and electrical shock hazards at the facility.
