Z--Provide Maintenance Repairs for Elevator Cables an

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the "Provide Maintenance Repairs for Elevator Cables and Painting of Structure" solicitation (Solicitation #140P5126Q0021) for Mammoth Cave National Park.

• PPQ Usage: Previous performance questionnaires (PPQs) from other agencies are acceptable if recent, relevant, and compliant with solicitation terms.

• Existing Coatings: Non-hazardous; lead abatement was completed in 2015. Contractors must conduct their own testing and comply with OSHA.
• SSPC/AMPP Certifications: SSPC/AMPP QP-2 certification is not required. Applicable SSPC standards (listed in the document) must be adhered to.
• Ambient Temperature: Approximately 55 degrees Fahrenheit, +/- 5 degrees.
• Elevator Shaft Safety Training: No specific certification is required, but contractors must ensure employees are physically qualified and trained for safe performance, including climbing and navigating the shaft.
• Paint System: The approved system uses Noxyde red primer and Noxyde federal gray finish (or approved equal), with specific ASTM requirements to be followed. Sherwin Williams Macropoxy 646 and Fast Clad HB are also recommended systems for approval.
• Bid Bond: Not required.
• Work Hours: Typically Mon-Fri, 7:00 am to 6:00 pm. Weekend, holiday, and nighttime work can be approved with 24-hour verbal notice to the COR due to the emergency nature of the project.
