KO Determination - Parallel Shaft Gear Box_Redacted.pdf

This document is a Contracting Officer's Determination for a Simplified Acquisition Threshold contract for USACE Louisville District. The procurement is for Horsburgh & Scott Parallel Shaft Gear Boxes (X-10834) for Smithland Locks and Dam, located 918.5 river miles south of Pittsburgh, PA on the Ohio River. The critical need is to replace existing parallel shaft gear boxes for the Tainter Gates, which are essential for controlling river elevations and ensuring safe navigation. Smithland L&D currently has 22 existing parallel shaft gear boxes across the dam infrastructure and requires (2) new parallel shaft gear boxes to have a spare set for potential changeout in case of failure.

The contract will be a sole source procurement from Horsburgh & Scott, the original manufacturer, who possesses the original as-built drawings and is the only contractor capable of providing exact replacements. The gear boxes have been in service since 1982 and are crucial for raising and lowering a 400-ton tainter gate to adjust water elevations. The procurement is funded through Operations & Maintenance, Army (OMA), with a period of performance of complete delivery within 6 months from award. The justification emphasizes the necessity of exact replacement to prevent potential catastrophic failure that could disrupt navigation and damage dam infrastructure.
