The existing piping and bypass valve assembly has been in service since 2005. Due to the continued growth of the USDA steam load, the bypass assembly is now undersized to allow for proper warmup and startup of the steam system that serves the south portion of the USDA campus.

B. Scope:

The contractor shall be responsible for removal and disposal of the existing 2” piping, bypass valves, piping components, insulation around the existing 14” steam valve and any other miscellaneous items. All products shall be disposed of in accordance with all Federal, State and Local codes. Contractor shall supply weight and type of all material recycled and weight and type of all material sent to landfill.

The contractor shall provide all necessary labor, parts, and materials to install 2” and 4” pipe, weld-o-lets, elbows, tee’s, reducers, flanges, pigtails, pressure gauges, gate valves, and insulation. All piping shall be schedule 80, all piping components and valves will be heavy duty.

All 4” piping and 4” fittings will be welded, and all valves will be flanged. All valves shall be accessible form the catwalk. All valves shall be Crane, Watts, or an approved equivalent.

Product substitutions shall be approved before project begins

All fabrication, erection and testing shall be in accordance with ASME B31.3, ASME B16.34, ASME B165 and all Federal, State and Local codes. All work performed will need to be documented IAW EPA standards/regulations.

A site visit is highly encouraged.

The qualifying test segment must be a 2-inch nominal pipe size with wall thickness within range of the WPS. Tests position shall be "6G" per ASME BPVC SEC IX. Welder qualifications must be current. If the qualification test is more than 6 months old, provide record of welding continuity for each welder. Record of welding continuity shall show that the welder in question has performed welding to the procedure in question without a 6 month continuous span of inactivity since the date that the welder qualification test was passed for the submitted welding procedure. Record of welding continuity shall include, at a minimum, the welder's employer name and address, the date the welder qualification test was passed, and the dates indicating welding continuity including welding procedure for each date. The contractor shall submit jobs completed that are of similar size and scope.

D. Project Timeline:
