Ward, Purchasing Specialist, (214) 819-7119. The U. S. Postal Service (USPS) is seeking to prequalify firms for the fabrication and installation of replacement AC drive systems at the Bulk Mail Centers. The USPS intends to replace about 150 existing DC drive systems on parcel/sack sorters with AC drive systems. The replacement AC drive system is defined as: AC drive controller (employing digital technology with on-board input/output logic interface and associated hardware) located in a single enclosure; high efficiency AC motor with brake and shaft encoder. Firms that are capable of manufacturing, installing, and providing engineering support for AC drive systems are invited to request a prequalification package. To be qualified firms must demonstrate 10 years experience in manufacturing drive controllers, which includes but is not limited to hardware and software documentation; technical training course development and presentation; engineering service support; removal of existing drive systems and installation of replacement drive systems; designing and providing site specifice spare parts kits. After written presentations are revised by USPS Prequalification Review Board, the Postal Service will determine which firms are qualified and eligible to receive the Request for Proposal (RFP). First article inspection is required sixty days after contract award. Under this proposed contract, the contractor will be required to custom redesign commercial off the shelf equipment to interface with existing parcel and/or sack sorter equipment. The contractor shall be responsible for removal of existing drive system, delivery new drive system, installation of the new drive system (using specific down-time windows so as not to interfere with mail processing operations), and testing of replacement sorter drive systems. Additionally, the contractor shall provide documentation (software/hardware) package and grant USPS all necessary rights to use subject documentation to develop a Drawing Package. Also, the contractor shall develop and provide training at each installation location as well as two technical training sessions at the Norman, OK, facility. Firms interested in prequalification must request a prequalification standards package no later than May 9, 1996. Your request for the prequalification standards package may be submitted by mail or by facsimile transmission. The mailing address is shown in block 7 above. The FAX number is 214/819-7125. Please send your request to the attention of Janis Nichols. Written prequalification presentations will be due at this office by close of business May 24, 1996. Interested firms are reminded that only those firms determined to be prequalified will be issued a RFP and considered eligible for contract award. The award of the subject contract is contingent upon evaluation of technical/management and pricing proposals. The complete requirement is subject to normal USPS management approvals. The tentative date for issuance of the RFP is June 10, 1996, with written proposals due on or about July 15, 1996. (116)
