THIS BOOK

The Federal Procurement Regulations System (Subtitle A of this title) consists of (1) the procurement policies and procedures for Government agencies prescribed by the Administrator of General Services (Chapter 1-Federal Procurement Regulations), and (2) regulations of various agencies implementing or supplementing the Federal Procurement Regulations (Chapters 2 through 49). In each of Chapters 2 through 49, the first 49 parts are reserved for regulations implementing the Federal Procurement Regulations and numerically keyed thereto; the remaining parts in these chapters will contain regulations supplementing the Federal Procurement Regulations.

Subtitle B (Chapters 50 through 100) consists of Government-wide regulations affecting procurement policies and procedures which are not included in the Federal Procurement Regulations System. Former Chapters II and III of Title 41, containing regulations of the Division of Public Contracts, Department of Labor, and the Committee on Purchases of Blind-Made Products, respectively, were redesignated Chapters 50 and 51 and assigned to this subtitle.

consists of (1) the property management policies and procedures for Government agencies prescribed by the Administrator of General Services (Chapter 101Federal Property Management Regulations) and (2) regulations of various agencies implementing or supplementing the Federal Property Management Regulations (Chapter 102 to end).

The numbering system of Title 41 is unique in the Code of Federal Regulations, and is especially designed to permit the keying of similar subject matter throughout the chapters in Subtitles A and C. Chapters are numbered in arabic. Each section number is a combination showing to the left of the decimal point the chapter and part numbers, separated by a dash. To the right of the decimal point the subpart, section, and subsection numbers are indicated in that order. Thus, an agency assigned to Chapter 2, and wishing to implement the cost-plus-a-fixed-fee contract provisions contained in Chapter 1, Part 1-3, Subpart 1-3.4, section 04, subsection 3 of the Federal Procurement Regulations (section 1-3.404-3), would assign the section number "2-3.404-3" to the implementing provisions.
