Hydraulic Hardline Piping

Form / Attachment / Pricing Sheet

This document provides piping plans for the NSWCCD Building 60, Room 172, and Building 19, Room B-Bay (Option) areas. It details the layout and estimated lengths of hydraulic piping, including existing and contracted non-welded piping.

• Hydraulic Piping (Existing): Depicts existing hydraulic lines.
• Hydraulic Non-Welded Piping (CONTRACT): Outlines the piping to be installed under the contract.
• Separate Hydraulic Pipes: Differentiates between Pressure, Return, and Drain lines.
• Hydraulic Valves: Indicates the location of individual ball valves for Pressure, Return, and Drain lines.
• Hydraulic Tees w/ Caps: Shows tees for Pressure, Return, and Drain lines.
• Equipment Locations: Identifies MTS (Material Test System) frames and HPU (Hydraulic Power Unit) locations.
• Estimated Piping Lengths: Provides approximate lengths for various piping segments.

This plan is crucial for bidders to understand the physical layout and scope of the hydraulic piping work required for the opportunity. It helps in visualizing the installation, estimating material needs, and assessing the complexity of the work in relation to specific equipment and building structures.

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

To provide and install non-welded steel piping in multiple laboratories at Naval Surface Warfare Center Carderock Division (NSWCCD) to supply hydraulic fluid pressure between existing and planned hydraulic power units (HPUs) and hydraulic testing systems.
