4.0. Government Furnished Equipment.
4.1 Introduction
A. Army Materiel Command (AMC) and its units use Total Asset Visibility – Contractor (TAV-C) capability in its Logistics Management Program (LMP) to account for Government Furnished Equipment, Materiel, or Property (GFE/M/P) placed in the possession of contractors to support contracts for: 1) repair, modification, or upgrade work; 2) materials held for Stock, Store and Issue (SSI), or 3) New Production. Accounting records within LMP for this inventory are subject to verifying physical inventories and audits by the Army to ensure accuracy. This section addresses contractor requirements for repair, modification and/or upgrade contracts.
4.2 System Overview and Portal Access Requirements
A. To use TAV-C, Contractors shall request one of two TAV-C access methods below to exchange required inventory data with LMP: 1) Defense Logistics Management Standards (DLMS) interface or 2) the Army TAV-C Portal. Approval of the contractor’s access method will be based first on the type of work being performed, second, the sufficiency of the contractor’s existing property accountability and connectivity to LMP, and third, request by the to use the portal based on economic factors.
B. Contractors can choose between the two methods for accounting for government property as further described below:
1. Defense Logistics Management Standards (DLMS) interfaces: Contractors that have accounting systems capable of using a DLMS interface (see: DLM 4000.25, Defense Logistics Management Standards (DLMS) on the Defense Logistics Agency (DLA) website) shall request to use their accounting system and interface to account for Government Furnished Equipment/Materiel/Property (GFE/M/P) using DLMS transactions.
NOTE: If a contractor does not currently have an established DLMS interchange with Defense Logistics Agency (DLA) Defense Automated Addressing System (DAAS), it will be the contractor’s responsibility to contact DAAS to establish access to DAAS messaging system to support the exchange of DLMS transactions with the Army. DAAS provides a value added service for standard Military Standards (MILS) transactions providing the ability to receive, edit and route logistics transactions for the Military Services and Federal Agencies. Information on DAAS can be found at https://www.dla.mil/HQ/InformationOperations/DAAS/
2. Army TAV-C Portal: Contractors who, during negotiation with the government, are determined to be allowed to use the TAV-C Portal, will comply with prescribed processes to provide qualified workers to access the system to exchange data with LMP.
C. Portal Access Requirements. Contractor personnel who input data into the TAV-C Portal, must meet qualification requirements specified in the TAV-C Portal Guide Detailed Procedures and requirements are detailed in the TAV-C Portal Guide. These requirements include:
1. Contractor provided computer system: The contractor shall provide a computer system and internet connectivity that meets acceptable standards as identified in the TAV-C Portal Guide.
2. Security Requirements.
(a) The government requires contractor personnel accessing the LMP system to possess either a United States Government Common Access Card (CAC) or a Department of the Defense approved External Certification Authority (EAC). To apply for these credentials, contractor personnel must possess a soft certification from a security credentialing firm.
NOTE: At the time of this writing, the government has successfully used IdenTrust and WidePoint (formerly ORC) for satisfactory credentials. It is the contractors’ responsibility ensure operators accessing the portal have and maintain current credential and to comply with the selected vendors’ service contract requirements. These firms are provided as a courtesy and are not an endorsement for any firm by the U.S. Government.
(b) Contractors will coordinate with the Contracting Officer’s Representative or designated government re presentative to complete required forms to obtain the CAC/EAC. This will require the above certification, forms of identification, etc.
3. User Training Requirements: TAV-C Portal user training is government provided and varies by the function performed. The training is online and completion of the training by each operator is required before accessing and using TAV-C.
4. The on-line training site will be provided by the government after award and access to the system has been granted. Functional training required to begin work should take no more than 15 hours to complete.
D. Problem Resolution: LMP is a government owned and maintained system. The contractor shall notify the COR or designated government point of contact for system related issues and government resolution.
4.3 DLMS Transactions / Portal Data Requirements
A. For DLMS Transactions for repair, modification and/or upgrade contracts, the inventory management transactions to be provided to the government by DLMS interface are:
1. DLMS 527R Materiel Receipt Acknowledgement (MRA) Transactions (for GFM expected to be consumed).
A. For DLMS Transactions for repair, modification, and/or upgrade contracts, the material receipt transactions to be provided to the contractor by the government via the DLMS interface are:
1. DLMS 527D Pre-positioned Material Receipt Document for stock in-transit to vendor.
B. Army TAV-C Portal: Contractors who, during negotiation with the government, are allowed to use the TAV-C Portal to exchange required data directly with LMP, will provide the following information via data inputs to LMP.
1. TAV-C Portal Requirements: Details on entry of the input into the LMP Portal will be provided as part of the government provided training.
2. The required data will be based upon the business process being performed. Inputs and input formats will be driven by the role performed for this work as directed in the contract.
3. The LMP Portal will provide to the contractor reports which will serve to inform the contractor and aid in work performance. Details on the various reports and how they can be used will be covered as part of the government provided LMP Portal training.
C. Consumption Reporting: Quarterly reports on the consumption of repair parts, disposition of equipment, and adjustments to inventories will be provided to the government as specified.
