About this file
This document is a Statement of Work (SOW) for upgrading the elevator cab door monitoring system at the USDA Agricultural Research Service facility in Gainesville, Florida. The SOW specifies that the existing elevators require an additional cab door monitoring system and logic to comply with ASME A17.3-2015 code requirements for safety enhancements on existing elevators. The scope of work includes installing a new logic system, cab door sensors, power supply, NEMA 1 cabinet, and updated software to ensure the elevators will not operate with faulty door contacts.
The related federal contract opportunity is a solicitation (Solicitation Number: 12405B24Q0539) issued by the USDA, ARS Southeast Area for the installation of the elevator door lock monitoring system described in the SOW. The solicitation requests quotes from responsible sources to provide and install the required system upgrades. Quotes must be submitted by 4:00pm CST on August 29, 2024, and will be evaluated based on technical capability, past performance, and price. Award will be made to the responsible offeror whose quote represents the best value to the government.
