About this file
This document is a Sole Source Justification for the purchase of a Hofmann Vertical Balance Machine for the Oklahoma City Air Logistics Complex (OC-ALC). The Air Force intends to award a firm fixed price, single source purchase order contract to American Hofmann Corp. (Lynchburg, VA) for the purchase, installation, and final setup of one (1) Hofmann Vertical Balance Machine. The Hofmann Vertical Balance Machine is used for testing and balancing low speed compressors and low speed turbine engine rotors. The justification cites that the Hofmann machine is the same brand as the existing machines used, allowing for immediate use without the need for extensive retraining of personnel. Retraining on a new brand would cost an additional $17,500. The machine will also allow the Air Force to better forecast its regular maintenance production engine rotor assets. The contracting opportunity has a NAICS code of 333998 with a size standard of 700 employees. Interested vendors must register in the System for Award Management (SAM) and submit a quote and capability information electronically through SAM.

The Hofmann Vertical Balance Machine that is being requested is the same brand as the existing machines in use and would allow for the immediate use of the new machine without the need for extensive training of personnel in the process and use of the operating system. The cost to retrain seven (7) personal on a new balancer if we went with another brand/vendor would cost an average of $2,500.00 per employee adding an additional $17,500.00 and days to retrain. This will cause a substantial duplication of cost to the Government that is not expected to be recovered through competition
. This vertical balance machine will allow the to better forecast its regular 2 level maintenance (2LM) production engine rotor assets by eliminating the need to work in the recycled engine rotors between the standard workload rotors. Rotor flow days on 2LM engines will be reduced as a result. The end item technical data also calls out the use of a Hofmann
Balance machine in TO 2J- -53-8 WP 008 00 as applicable support equipment. The procedures in Paragraph 3 of work package 008 00 are written specifically for set-up and balancing procedures on a Hofmann balance machine. Also, for the vertical balance procedure in WP 006 00, a recent AutoTAR 202 (tech data change request) was approved (ENG-202-2022-100406) to call out Hofmann name brand. On a previous acquisition, contract FA813223P0015 awarded to American Hofmann Corporation as a Sole Source Vendor for the purchase of a vertical balance machine.
