The General Services Administration Acquisition Manual (GSAM) provides the General Services Administration Acquisition Regulation (GSAR) and related internal agency acquisition policy in a convenient, integrated format. Regulatory material in the text appears in shaded background, and is easily distinguished from policy material, with both following a consistent number format that coincides with the Federal Acquisition Regulation (FAR). The 2013 edition incorporates hundreds of changes that were made since the prior edition was published. The changes relate to a wide variety of subjects, including: Acquisition letters Acquisitions involving classified information Awards involving subcontracting plans Breaches of security Content of contract files Contract distribution procedures Contracting officer's signature Control of classified information Direct 8(a) contracting Federal Procurement Data Systemand—public access to data Final paymentand—construction and building service contracts Information technology security plans and security authorization Mentor requirements and evaluation Model small business subcontracting plan Notice to offerors of subcontracting plan requirements Personal identity verification requirements Postaward responsibilities of the contracting officer Preparation, submission, and negotiation of subcontracting plans Procedures for closing out contract files Processing security requirements checklist Responsibilities of the administrative contracting officer Return of classified information Reviewing subcontracting plans Security requirements for unclassified information technology resources Storage, handling, and disposal of contract files
