Mobil DTE Heavy ISO VG 100 turbine oil brand

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the storage and delivery of oil, clarifying aspects of the Statement of Work (SOW).

• Storage Duration: Oil will be stored outside for the 14-day waiting period. Totes are considered problematic compared to a tanker truck for this storage phase.
• Storage Space: An outside parking lot approximately 135ft x 70ft, located within 100 yards of the connection point, is available for tank/tote storage and secondary containment.
• Post-Testing Responsibilities: After testing approval, the contractor is responsible for returning to the site to pump the product into the USACE tank. The hookup location is at a higher elevation, allowing for gravity feed. USACE will manage valve manipulation on the facility side.
• Delivery Distance & Hose Length: The approximate distance from the oil delivery location to the storage location is short, suggesting a 10-foot hose would be adequate. The connection size appears to be 3"NPT or 3"camlock.
• Delivery Process: The process involves delivering oil, storing it for 2 weeks using a storage barrier, contractor sampling for USACE lab testing, and upon passing results, offloading the oil into the system. The contractor will then remove their storage barrier and any empty totes.

This Q&A clarifies logistical details regarding oil storage, delivery, and the contractor's responsibilities, which may impact how bidders plan their approach and resource allocation.
