Boiler Plant Steam Pressure Reducing Valve (PRV) Stations #1 and #2 Replacement Project 689-24-130-BoilerPlant PRV Stations #1 and #2 Replacement

A. GENERAL INFORMATION

1. Title of Project: 689-24-130 BoilerPlant Steam PRV Stations #1 and #2 Replacement

2. Project Location: VA Connecticut Healthcare System, 950 Campbell Avenue, West Haven, CT 06516

3. Background: There have been repeated issues with calibration and adjustment of the steam PRV stations and have safety deficiencies due to age and operating conditions. The purpose of this project is to replace the stations and correct critical safety deficiencies.

4. Scope of Work: The contractor shall provide all labor, supervision, materials, equipment, tools, services necessary to size, select pressure reducing valves, shut-off valves, strainers, safeties, steam traps, flow meter and other associated steam and condensate components contained within the 2 steam pressure reducing stations located within the Boiler Plant.

a) Provide piping and instrumentation diagram, complete equipment schedule and sizing in PDF and CAD formats. Package shall be submitted to the VA within (30) days following the notice to proceed.

b) Perform all necessary field measurements and investigations to assure that the equipment and assemblies will meet contract requirements and will fit the space available.

c) Provide demolition plan, shop drawings, weld map, equipment list drawing and as built plans in PDF and CAD formats, approved by an independent engineer. The engineer shall be a subcontractor of the General Contractor and shall report to and be paid by the General Contractor.

d) All work shall be performed offsite. Prefabricate all piping, perform radiographic testing of 100% of the butt-welded joints and pressure test all piping (including header, spool pieces, steam trap assembly piping, etc.) offsite. All piping shall be assembled onsite at the VAMC, ensure to leak test all joints after the tie-ins.

e) Complete the steam PRV stations installation tie-ins during one steam shutdown. Steam shutdown shall only occur between May 1st through September 30th. 30 days advance notice required.

j) Pressure Reducing Valves in steam PRV Stations shall have stainless steel diaphragm.

k) Specification SECTION 23 21 11, BOILER PLANT PIPING SYSTEMS and sections listed under 1.2 Related work shall be based as the main specifications. The most stringent requirements shall always apply including unedited sections.

l) Provide removable insulation jackets for the new PRVs and steam trap assemblies.

m) Provide aluminum jacket over insulation from zero to 6 feet above floor.

n) Trap failure indications and feedback of all flow meters shall be tied into building automation system.

o) Provide an approved independent commissioning agency. The commissioning agency shall be a subcontractor of the General Contractor and shall report to and be paid by the General Contractor and identified by the General Contractor within sixty (60) days after the Notice to Proceed. The commissioning process shall encompass and coordinate the written PRV station startup procedure, system documentation, equipment startup, control system calibration, testing and balancing, performance testing and training.

p) Provide an approved independent testing firm regularly engaged in radiographic testing to perform the radiographic examination of pipe joint welds on behalf of the VA. Testing firm shall be a subcontractor of the General Contractor and shall report to and be paid by the General Contractor and identified by the General Contractor within sixty (60) days after the Notice to Proceed. To receive approval onsite radiographic testing for tie-in welds, provide:

1. Up-to-date radiation safety training and certification.

2. Current NRC [or Agreement State] License to possess and use the source(s) they plan to bring to onsite testing.

3. Agreement with the CT DEEP in terms of using their source(s) in the State of CT.

4. Radiation Safety Officer to respond to emergencies in a timely manner.

5. Multiple radiation detectors that are up-to-date and in calibration, to monitor themselves, the source, and the perimeter for radiation doses.

6. Passed ‘leak testing’.

7. Written emergency response plan in case the radioactive source doesn’t retract back into its shield, or for other emergencies.

8. A security plan to prevent loss or theft of the radioactive material.

9. Written method/plan for determining the size of the restriction area and provide drawing showing the restriction area. Evaluation of the restricted area needs to include floors above, and adjacent to the radiation imaging areas.

10. Signs, ropes, and other barriers to clearly define the restricted areas to keep people away.

q) Perform radiographic testing of 100 percent of the welds. All radiographs shall be reviewed and interpreted by an ASNT Certified Level III radiographer, employed by the testing firm, who shall sign the reading report.

r) Ensure construction materials meet the domestic content requirements to comply with the Buy America Act (See FAR Subpart 25.2)..

s) Provide Construction work plan, Schedule, Safety Plan (Accident Prevention Plan), Waste Disposal Plan, OSHA worker certifications and training, Welder Qualification, Safety Data Sheets (SDS), weld X-ray inspection report and pressure test data from start to finish recorded by digital pressure recorder with full record and data to be provided to the VA.

t) Material submittals shall include the applicable VA specification section with applicable paragraph identification and shall include clear identification of specific materials proposed for project.

1. Manufacturers’ Literature and Data including: Full item description and optional features and accessories of the complete system including, but not limited to, dimensions, weights, materials applications, standard compliance, model numbers, size and capacity. Submit Pipe and tubing, with specification, class or type, and schedule. Pipe fittings, including miscellaneous adapters and special fittings. Flanges, gaskets and bolting, Valves of all types, Strainers, Gauges, insulation, and all other steam system components.

The project shall be accomplished in compliance with all applicable standards and codes specified in the VA Design Guides and Manuals and all applicable VA requirements. VA specifications can be found at the VA Technical Information Library: Technical Information Library (TIL) - Office of Construction & Facilities Management (va.gov).

The most stringent requirements of the SOW, local codes or the specifications requirements shall always apply. Any conflicts shall be brought to the attention of the COR.
