About this file

This document is an Amendment (Amendment 0003) to a federal solicitation for the B-179 Deep Depth Test Facility Improvements Project at the Naval Undersea Warfare Center in Newport, Rhode Island. The amendment serves two primary purposes: (1) providing updated responses to pre-proposal inquiries and (2) providing an additional attachment (Attachment K - B-179 New Site Work Plans & Details C-4). The pre-proposal inquiry responses address specific technical details, including clarification about existing rail system support (8' long wooden ties likely treated with creosote) and a requirement for the contractor to replace all door hardware within the project's work area, as listed in the Door Schedule on Sheet [A-601].

The solicitation is specifically restricted to Multiple Award Construction Contract (MACC) holders under contract N4008521D0052-57, 0066, covering facilities in the North Area of Responsibility, which includes states from Connecticut to Vermont. The amendment is part of a Design-Bid-Build (DBB) project, with the contract point of contact being Jator de Leon, and the effective date of the amendment is 08/06/2025. Prospective contractors must acknowledge receipt of this amendment prior to the specified submission date and adhere to the updated technical specifications and requirements.

AMENDMENT 0003

This amendment is issued to incorporate the following:

1. Provide and update responses to Pre-Proposal Inquires

2. Provide Attachment K – B-179 New Site Work Plans & Details C-4 (attached separately)

1. Provide and update responses to Pre-Proposal Inquires

Reference Question Government Response Page Section Paragraph

As Boring B2 only indicated 6” of concrete, how is the current rail system supported and fastened? Do the rails fasten into any type of rail-tie system such as concrete or wood? If wooden, are the rail-ties creosote treated timber?

The rails are supported by 8' long 7" x 9" wooden ties at 15 1/2" O.C. Based on the age of the existing ties, it is likely that they are creosote-treated timber.

However, this has not been confirmed. Please see Attachment K – B179 New Site Work-Plans & Details provided with Amendment 0003.

9 A201 A201 indicates all existing hardware that does not work be replaced. Can a list be provided of what hardware does not work or should the contractor carry an allowance to cover the cost of this hardware.

Updated PPI Response - The Contractor is responsible for replacing all door hardware for all doors within the area of work for the contract. These doors are listed in the Door Schedule on Sheet [A- 601].

2. Provide Attachment K – B179 New Site Work Plans & Details C-4 (attached separately)
