About this file

This document is a Past Performance Questionnaire (PPQ) issued by the U.S. Air Force Pacific Air Forces at Yokota Air Base for a competitive source selection for Operation and Maintenance (O&M) services of Defense Information Systems Network (DISN) Power Plants and Station Battery Systems. The document serves as Attachment 3 to Solicitation No. FA520926Q0004 and requests references to provide frank assessments of contractor performance on related contracts or work efforts. Responses must be submitted by February 19, 2026, to MS. Mio Miyabayashi (primary) or Mr. Benjamin Warren (alternate) via fax at 042-530-3319 (Japan) or 011-81-42-552-3011 (U.S.), or email to mio.miyabayashi.jp@us.af.mil or benjamin.warren.7@us.af.mil. Completed questionnaires become official Source Selection records and respondent names will be kept confidential.

The questionnaire uses a six-point rating scale (Exceptional, Very Good, Satisfactory, Neutral, Marginal, and Unsatisfactory) to evaluate contractor performance across key areas including quality of work, quality control and inspection procedures, timely performance and schedule adherence, effectiveness of issue and complaint resolution, and compliance with applicable rules, regulations, laws, and safety standards. Section 2 requires references to provide detailed contract information including contractor name, address, contract number, period of performance, place of performance, total contract amount, and services provided. The document includes checkboxes for relevant service scopes such as O&M services for generators 1000KW or above, UPS systems, frequency converters, parallel operation systems, 24-hour on-call services, and emergency repairs by licensed technicians. Section 3 collects respondent identification information, and Section 4 includes questions assessing overall satisfaction with contractor performance and whether the reference would hire the contractor again.
