Questions & Answers / Clarifications

This document provides clarifications and answers to vendor questions regarding the solicitation for an unspecified opportunity. It addresses technical specifications, material requirements, and submission procedures.

• Tapped Holes: Confirmed that tapped holes are not included on the back side of Quoin and Miter blocks.

• Part Fabrication: It is acceptable to make part MK 21/10-12 from a single piece forging instead of welding rings to the forging, and to machine the entire part without welding if it shows welding in the drawings.

• Shop Drawings: Official shop drawings are not required as a formal submission, but USACE is willing to review contractor-created shop drawings prior to fabrication.

• Delivery Date: The required delivery date has been extended to December 18, 2026.

• Assembly Costs: Assembly costs should be included within the CLINS for the components, as there is no separate CLIN for assembly.

• Material Substitution: Rolled plate steel may be acceptable in lieu of forged steel (ASTM A668, Class D or K) if it meets or exceeds specified mechanical properties, but the proposed material must be known.

• Documentation Submission: Examples of certificates of compliance, material test reports, and non-destructive testing reports are not required in the quote package. However, the cost for these documents should be included in the contract bid, and the documentation will be submitted after award.

• The delivery date has been extended.

• Clarifications on material and fabrication methods may affect how vendors approach their proposals and cost estimations.
