Questions & Answers / Clarifications

This document contains responses to vendor questions regarding the procurement of air compressors, clarifying technical specifications, installation requirements, and contractual details.

• Electrical System: The existing system is 240V, 3-phase, 4-wire DELTA, with 4AWG wiring from the panel to the disconnect.
• Compressor Configuration: A lead-lag configuration is required, where units alternate as the lead unit. A single starter and microprocessor to run both compressors is not an option.
• Dryer Requirements: A separate air dryer is required, not integrated. The dryer shall be sized to handle both compressors operating in a lead-lag configuration. There is only one air dryer specified.
• Performance Requirements: Compressors must meet the CFM and PSI requirements shown on Drawing M-01. The specific horsepower (e.g., 30 HP vs. 25 HP) is secondary to meeting these performance metrics.
• Installation & Responsibilities: The Contractor is responsible for all work, equipment, materials, and disposal (including oil and water removal). The contractor will also unload equipment upon delivery.
• Piping: Piping shall be copper and must be soldered; pro-press or other fittings are not allowed.
• Set-Aside: This opportunity is a set-aside for small businesses of any type.
• Country of Origin: No country-of-origin requirement as this is a Commercially Available Off-the-shelf Product.

This Q&A document provides critical clarifications that bidders must consider when preparing their proposals. It refines technical specifications, installation responsibilities, and configuration requirements, directly impacting the scope of work and pricing.
