1.0 SCOPE OF WORK:

Extend existing ASW piping, at the same height as the existing, from the end of the existing North side piping and around the Dry Dock 1 service tunnel to two new branch lines serving the balconies on the South side. These branch lines must be cored through the dry dock in locations indicated on the drawings. The service tunnel is a confined space and all work shall meet OSHA and EM 385-1-1 confined space requirements. The service tunnel has piping for high-pressure air, steam and other utilities and great care must used to not disturb or interrupt these utilities.

Assume that this work will happen while a boat is in dry dock. This means that work on the balcony area of the dry dock will be cramped with wiring and piping for various utilities serving the boat. Extra precautions must be taken to not disturb or interrupt these utilities.

The space surrounding this area is busy with construction from other projects. It should be assumed that not all the access hatches used for tunnel access will be available for the duration of the project. Access locations may have to change in support of shipyard operations.

The work includes the following and incidental related work:

WALL PENETRATION WORK

1.1. Drill two holes through the Dry Dock 1 service tunnel out to the balcony to accommodate the 6” piping. Keep holes as small as possible.

1.2. After piping is installed and tested provide non-shrink grout around the 6” branch pipe holes. Grout will serve to provide support for the 6” balcony isolation valve.

1.3. After piping is installed and tested provide polyurethane, closed cell, foam in place, caulking to seal around all penetrations not sealed with grout.

PIPING MATERIAL REQUIREMENTS

1.1. The basis of design piping is Aquatherm brand, blue pipe SDR-11 faser-composite PP-R pipe. This is the existing type of piping and this project shall be compatible with this type of piping.

1.2. Provide and install flanged rubber expansion joints as indicated on the drawings.

Expansion joints shall be capable of accommodating an expansion of a 75-degree temperature delta in the event that a steam leak in the tunnel occurs when the ASW system is off. Expansion joints shall meet the requirements of spec section 23 64 26, be compatible with piping manufacturer’s requirements and be rated for travelling the distance calculated for the temperatures stated above.

1.3. 10” valves shall be 316 stainless steel knife gate valves.

1.4. 6” valves shall be 316 stainless butterfly valves with stainless steel level locks for termination in the balcony.

1.5. All valves shall include 150# class flanges for servicing.

1.6. All mechanical and flanged joints should be made with stainless steel rings, fasteners and gaskets compatible with and per polypropylene-random (PP-R) pipe manufacturer’s requirements.

1.7. Provide and install cleanliness blank and small drain valve to cover the exposed side of the last gate valve.

1.8. Hangers and anchors shall be type 316 stainless steel.

PIPING INSTALLATION

1.1. Make final connection to the existing ASW piping after the new section has passed pressure testing and the system has been flushed. At a minimum provide a 2 week notice before the final connection so that the proper ASW outage and coordination can be requested by Code 984 and the Dry Dock operations personnel.

1.2. Extend the existing ASW piping, at the same height, around the Dry Dock service tunnel as indicated on the drawings.

1.3. All PP-R piping connections shall be fused connections completed by a mechanic qualified in accordance with the manufacturer of the piping manufacturer utilizing the tooling required by manufacturer. Butt welded type connections are preferred.

Electrically fused socket type connections shall also be accepted where necessary.

Heat fusion shall be in accordance with ASTM F 2389. The intent is to reduce the number of bolted mechanical joints to areas where required only, such as valve and expansion joint connections.

1.4. Maximum spacing between hangers for basis of design 10” piping is 8’. Support piping per manufacturer’s requirements.

3.0 GENERAL REQUIREMENTS:

All work performed by the General Contractor shall be in accordance with the requirements specified in herein and the project specifications and all local, State and Federal Codes.

The means and methods of work associated with this project shall be in accordance with the tasks specified on the enclosed contract documents and the following general requirements:

3.1. Division 01 - General Requirements Specification

All requirements of Division 01 apply to this project unless otherwise noted herein or other contract documents or if means and methods do not invoke the requirement (i.e.: no confined space, no hazardous waste, etc.). Refer to the Attachment 4 Submittal Register for additional items that do not apply which are not otherwise explicitly identified as such herein.

3.2. The Contractor shall coordinate all work to permit Navy/Facility Operations to be performed during the course of work. It is anticipated that the Contractor may need to work outside normal work hours and /or weekends to ensure Shipyard/Facility operations are not impacted by work performed by Contractor.
