This is a Single Source Justification document submitted by the U.S. Department of State to procure critical parts for elevator repairs on a sole source basis.

The U.S. Consulate General in Karachi is seeking to procure elevator inverter modules and related services necessary to restore operational functionality to the SDA 1 elevator 907 at the facility. The estimated procurement value is $30,000. The requiring activity is the Facility Management Office (FAC) under project PR1590207. The procurement requires supply of proprietary parts certified by Kone Elevator, installation by trained and certified elevator mechanics, testing and calibration to ensure safe operation, and compliance with all manufacturer-recommended procedures to maintain warranty and operational reliability. The sole source contractor identified is M/S Duncan Stratton & Co Pvt Limited, the authorized sole service provider and distributor for KONE Elevators in Pakistan. The justification cites urgency, exclusive licensing agreements with the elevator manufacturer, brand-name requirements, and the contractor's unique qualifications and established preventive maintenance contracts with U.S. Embassy Islamabad and U.S. Consulates in Karachi, Peshawar, and Lahore. The Contracting Officer has determined the anticipated cost of $30,000 is fair and reasonable based on historical project information, independent Government Cost Estimate, and comparison with the current preventive maintenance contract. The document was approved on March 16, 2026, by Ani Akinbiyi, General Services Officer at the U.S. Consulate General Karachi.
