Questions & Answers / Clarifications

This document provides responses to vendor questions regarding Solicitation W9133L-26-Q-0001.

• Set-Aside: The solicitation will remain a 100% small business set-aside; large businesses cannot offer.
• Scope of Work: Bidders must quote engines and associated parts, including installation labor as required by the Purchase Description's "PERFORMANCE OBJECTIVES AND STANDARDS" which mandates the installation of Ending Assembly Kits.
• Virtual Training: No virtual training is required.
• Tariffs: Offerors are responsible for accounting for all market impacts, including tariffs, in their pricing and delivery quotes.
• Application Type: This solicitation is for new engines and assembly kits to be delivered to Minot, ND, for replacement by the Civil Engineer Technical Branch (CETB). It is not for replacing existing Deutz engines in the field.
• Core Credits: Since this is not for replacing existing Deutz engines, core credits are not applicable.
• Pedestal Weldment: A new pedestal weldment with hardware will not be required for attaching the gauge panel; the gauge panel will be installed by CETB.
• Heat Shields: Additional heat shields beyond those native to the engines will not be required.

These clarifications do not appear to alter any requirements, due dates, or submission rules of the original solicitation, but provide essential details for accurate quoting.
