Vibration Test System

Statement of Work (SOW) / Performance Work Statement (PWS)

This Statement of Work (SOW) outlines the requirements for a Vibration Test System to support environmental testing of spacecraft components and aeronautical research at the Air Force Institute of Technology (AFIT). The system is needed due to the failure of the previous system and the inability to repair an older one.

• Procurement of a vibration test system including a slip table, shaker, and control/data collection electronics.

• The slip table should be at least 30x30 inches with a low-friction surface and a specific bolt pattern for mounting hardware. An expander head for vertical axis testing may be included.

• The shaker must meet minimum technical requirements including load capacity (29 kN / 6,540 lbf), frequency response range (20Hz to 2,000Hz), and power requirements (480V 3 phase, 60 Hz or 208V 60Hz or 110V 60Hz).

• The shaker control system must include calibration to NIST standards and programmable control profiles for sine sweep, track and dwell, random vibration, and shock test profiles.

• The data collection system requires calibration to NIST standards and a minimum of 8 accelerometer input channels (expandable to 16).

• Test requirements are governed by MIL-HDBK-340A (USAF), MIL-STD-1540D, and GSFC STD-7000A.

• Shaker load capacity: 29 kN (6,540lbf) in sine or random vibration profiles.

• Frequency response range: no less than 20Hz to 2,000Hz.

• Data collection system: Minimum 8 accelerometer input channels.

• Delivery Lead Time: NLT 12 Weeks after contract award.

• Delivery Location: SHIP TO DODAAC: F4F5AV, AFIT/ENY, 2950 Hobson Way, WPAFB OH 45433.

• All delivered hardware must pass through a 70” wide, 78” tall doorway with a 6” wide jam. If the fully assembled unit cannot pass, it must be delivered as sub-assemblies with vendor-provided rigger services for on-site assembly.

• Products delivered must be manufactured in a qualifying country source per DFARS 225.872.

• Contract price includes on-site training for 2 AFIT/ENY technicians and on-site setup and installation.

• Shipping costs, including insurance, are to be included in the proposal. Specific delivery procedures for commercial vehicles, including inspection at Wright-Patterson Air Force Base Commercial Vehicle Delivery Gate (CVDG), are detailed.

Questions & Answers / Clarifications

This document provides clarifications and answers to vendor questions regarding Solicitation FA860126Q0012 for a Vibration Test System.

• Origin of Shaker: The solicitation requires a brand name ETS Solutions shaker. Due to the Buy American Act, products manufactured in China are not acceptable. Products manufactured in Japan are acceptable as Japan is a qualifying country under DFARS 225.872-1.
• Physical Fit: The vibration test system must fit into the building, down a hallway, and through a specific doorway. Exact dimensions are detailed in Section II of the SOW.
• Payment Terms: The government's stance of 100% payment upon final acceptance/installation is firm.
• Delivery Timeline: While delivery is noted as 12 weeks or less, faster delivery is acceptable. A vendor offered delivery in approximately 2 weeks with a slightly larger slip table (1 meter x 1 meter instead of 800mm x 800mm), which is acceptable provided it fits through the specified doorway and the bolt pattern meets the solicitation's requirements.

This Q&A clarifies acceptable manufacturing origins, confirms payment terms, and provides flexibility on slip table dimensions and delivery timelines, provided all physical constraints and technical specifications are met.

Other / Unclassified

This document is a Single Source Justification (Simplified Acquisition) for the "AFIT Vibration Test Systems" project. It outlines the government's rationale for procuring a vibration test system from a single source, specifically Brand Name ETS Solutions.

This document is relevant to potential bidders as it explains why a single-source award is being considered for a vibration test system. It details:

• Supplies/Services Required: A vibration test system including a shaker head, slip table, blower unit, signal amplifier, control unit with data collection, delivery, installation, and training.
• Justification for Single Source: ETS Solutions is cited as the sole manufacturer capable of providing a system with unique capabilities (proprietary iDOF software for precise control) and meeting specific technical requirements (32-bit digital to analog conversion, high accuracy software for power spectral density testing).
• Existing Infrastructure: Other labs at WPAFB (including AFRL) already use ETS systems, facilitating easier support, sharing of hardware/software/expertise, and potential cost savings on maintenance.
• Market Research: While six companies were identified, only ETS Solutions was found to meet the specific technical requirements after a sources sought notice. Other vendors' capability statements were deemed technically unacceptable.
• Steps to Preclude Future Single Source Awards: The justification notes that ETS is the sole manufacturer but has authorized resellers, and that other vendors are expected to improve their offerings in the future.
• Contracting Officer's Determination: The Contracting Officer has determined that a single source is reasonably available in accordance with FAR 13.106-1(b)(1).
