STATEMENT OF WORK (SOW)
1. Background, Purpose & Scope of Work
Two stands are inoperable in the structures and materials laboratories (buildings 1205) within the Durability Damage Tolerance and Reliability Branch (DDTRB). One actuator needs repairs for a MTS controlled hydraulic test stand and a set of 100kip grips need to be put into service for upcoming work. Currently these test stands are inoperable and need parts replaced or rebuilt.
This Statement of Work (SOW) defines the equipment procurement, engineering integration, onsite installation, commissioning, and services to be delivered. The scope is divided into two primary jobs:
• CLIN 1: Delivery and installation of a 500 kN high-capacity hydraulic grips and fixtures package.
• CLIN 2: Supply and integration of a replacement 22 kip MTS actuator engineered to retrofit an existing Instron 1332 load frame.
