INTRODUCTION _____________________________________________________ 1. Background: a. During the next several years, Army facility funds will continue to be cut to reduce budget deficits. This means that Operations and Maintenance (O&M) dollars must be spent where they will do the most good. There will be less funding available for correcting unwise decisions and deficiencies in contracts. Managers will remain responsible to the Commander to ensure that the mission is accomplished. Further, these managers will not likely be relieved of their responsibility by virtue of contracting out the work. b. Performance Work Statement (PWS) writers and all others involved in contractual matters have a responsibility to develop the best possible acquisition packages. They also have a duty to utilize the most efficient methods within available resources. Incorporating these practices right from the start will help prevent future problems; therefore, the purpose of this guide is to implement effective procedures. 1 1-1 2. How_to_Use_This_Guide: a. This guide follows the Uniform Contract Format (UCF). This format covers SECTIONS A through M, each of which comprise standard subject matter pertaining to Air-Conditioning and Refrigeration Plants and Systems Operations and Maintenance Service Contracts. The guide is designed to give PWS writers detailed instructions on the content to be inserted in each section using UCF. b. Users of this guide will see the phrase NOTE_TO_WRITER throughout the narrative. When this phrase appears, instructions to PWS writers will clarify, expand upon, or recommend changes to the standard statements or other information provided, so that requirements peculiar to an individual installation can be addressed. These notes, where they are included, should be carefully read in the context of the surrounding guide paragraphs to gain a clear understanding of their meaning and intent. c. Users will quickly become aware that contract terms and language, which are mainly derived from the Federal Acquisition Regulations (FAR), are used throughout this guide. The purpose of their use is twofold; first, to allow managers to develop a PWS in appropriate contract "language" that states exactly what the DPW requires; second, to educate DPW users in contract terminology and Directorate of Contracting (DOC) users in DPW functions. 2 1-2 d.
