JHK RIGHT WING DIKE SOIL SAMPLING

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding Solicitation Number W912PM26QA026 for JHK Right Wing Dike Soil Sampling.

• Award and Sample Delivery: Award is projected around April 16th-17th. Samples have already been collected and will be delivered by USACE or mail as soon as practicable after contract award.
• Sample Material and Transfer: USACE has collected samples (approx. 1-2 lbs each in quart-sized bags) and will transfer them to the contractor via mail, courier, or hand transport. USACE will provide a plan for blending remaining material and Proctor test information after initial lab tests (Phase 1 & 2) are complete. Phase 3 involves remolding up to 20 blended samples.
• Sample Retention: Lab test samples are to be retained only for the duration of the lab testing contract. Disposal coordination with USACE is required at contract conclusion.
• Prior Experience: Ongoing projects are acceptable for demonstrating prior experience if "proof of satisfactory performance" can be provided. Otherwise, prior project examples are needed.
• Lab Validation: AASHTO-validated labs are suitable for this project.
• Proctor Testing: ASTM D698 Standard Proctor Test is expected to be sufficient.
• Sieve Requirements: The specified sieves (1-in., ¾-in., 3/8-in., No. 4, No. 10, No. 20, No. 40, No. 60, No. 100, No. 140, No. 200) will suffice.

These clarifications provide specific details on project timelines, sample handling, testing requirements, and proposal submission criteria, but do not appear to alter the core requirements or submission deadlines of the original solicitation.
