K--Medical Gas Isolation for 3rd and 5th Floors

STATEMENT OF WORK Medical Gas Isolation for the Third and Fifth Floors VA Medical Center, Manchester, NH OVERVIEW: The purpose of this project is to disconnect the branches of the oxygen, medical air, and vacuum systems serving the third and fifth floors of Building 1. These floors are no longer patient care areas and do not require these systems. TASK: For each medical gas system (oxygen, medical air, and vacuum) on the third and fifth floors of Building 1: " Disconnect the branch of the service for the floor. Install a brazed cap on the cut end of the abandoned pipe. " Install a new service valve on the branch off of the riser. Leave enough of an extension downstream of the valve to allow for recutting and brazing, in accordance with NFPA 99, 2012 edition, paragraph 5.1.4.10.2. Install a brazed cap at the end of the pipeline. " Once the service is disconnected, label all alarm panels, zone valve boxes, and outlets/inlets as "Not in Service." Labels shall be approved by the project COR before being applied. See Appendix A for a list of locations of these items. The medical gas systems must pass third party certification and be put back into service prior to project completion. The contractor shall be present during the third party certification. This project includes all work required to perform the tasks above, including system shut downs, purging, maintaining system cleanliness, taking care of any issues with the alarm panels, and disposal of waste. See Appendix B for photos of existing conditions. SCHEDULING: All work requiring a medical gas riser to be shut down shall be conducted outside of normal business hours, which are 7am - 4:30pm, M-F.

Applicable VA publications and design manuals are available to the successful bidder at www.va.gov/facmgt. VA personnel familiar with the facility's physical plant and structures will be available during the field investigations. It is expected that the Contractor will view the site and verify all information necessary for the development of the work plan. The Contractor shall set up appointments with the COR for these site investigations at least three (3) workdays in advance of the date of the planned visit. All debris shall be transported from the work site in covered containers. Dumpsters also must be covered while they are on VA property.
