ARCHITECTURAL / ENGINEERING SERVICES SUPPLEMENT B TO SF252 PROJECT TITLE: HVAC CONTROL UPGRADE PROJECT NO: 630-08-105 SCOPE OF WORK I. PROVIDE THE SERVICES OF A PROFESSIONAL ARCHITECT-ENGINEER FOR THE VA MEDICAL CENTER, 423 EAST 23RD STREET, NEW YORK, NY 10010 TO DESIGN THE FOLLOWING ITEMS: IT IS PROPOSED THAT THE EXISTING OUTDATED N-8000 BASED ATC SYSTEM BE REPLACED WITH A CURRENT STATE OF THE ART SYSTEM. THE SCOPE SHALL INCLUDE REPLACEMENT OF THE HEAD END, INCLUDING ALL ASSOCIATED PERIPHERAL DEVICES, REPLACEMENT OF THE NETWORK COMMUNICATION SYSTEM WIRING, UP TO AND INCLUDING REPLACEMENT OF THE MAIN "UPPER LEVEL" CONTROLLER PANELS, "GCM 01, GCM 02, GCM 03 AND GCM 04". IN ADDITION, THE SCOPE SHALL INCLUDE THE REPLACEMENT OF THE OLDER OF THE "SECONDARY NETWORK LEVEL CONTROLLERS", (LOCATIONS SHOWN AS "MZ" AND "MF2" IN THE ENCLOSED "ARCHITECTURE" SKETCHES) INCLUDING THE ASSOCIATED COMMUNICATION WIRING FROM THE UPPER TO SECONDARY LEVEL NETWORK CONTROLLERS. THE EXISTING "MNL" LOWER LEVEL CONTROLLERS ARE TO REMAIN; NEW CONNECTIONS SHALL BE MADE BETWEEN THESE AND THE NEW "UPPER LEVEL CONTROLLERS. EXISTING COMMUNICATION WIRING AND/OR PNEUMATICS ARE TO BE RECONNECTED AT EACH NEW DDC PANEL.. THE NEWLY UPGRADED SYSTEM SHALL BE FULLY CAPABLE OF SUPPORTING WEB BASED ACCESS FOR COMPLETE FUNCTIONALITY. CONSIDERATION SHALL BE GIVEN TO REPLACING THE EXISTING SYSTEM WITH THE "TAC / I/A" SERIES SYSTEM THAT IS EVOLVED FROM THE FORMER ATC SYSTEM THAT IS NOW IN PLACE. THE SCOPE OF WORK DOES NOT INCLUDE REPLACEMENT AND/OR REPAIR OF EXISTING "END USE" DEVICES SUCH AS DAMPERS, ACTUATORS, VALVES, SENSORS, VAV AND CONSTANT AIR VOLUME TERMINALS, VFDS, ETC. AS PART OF THIS PROCESS, THE CONSULTANT SHALL CONSIDER THE POSSIBILITY OF BOTH REPLACING THE EXISTING SYSTEM WITH THE PRODUCT OF A NEW MANUFACTURER AS WELL AS UPGRADING WITH THE SAME MANUFACTURER, WITH EMPHASIS ON PROVIDING VAMC WITH THE MOST RELIABLE AND COST EFFECTIVE SOLUTION. INTERFACE CAPABILITY WITH THE EXISTING COMPONENTS THAT ARE TO REMAIN SHALL BE ENSURED. A PROPRIETARY BMS VENDOR PROPOSAL HAS BEEN SUBMITTED TO VAMC. THE CONSULTANT SHALL REVIEW THIS PROPOSAL AND PROVIDE COMMENTS TO VAMC AS PART OF THIS SCOPE. THE REPLACEMENT SYSTEM SHALL ENSURE BACKWARD COMPATIBILITY THROUGHOUT THE LIFESPAN OF ALL EXISTING COMPONENTS, IN BOTH HARDWARE AND SOFTWARE, AND SHALL ALLOW FOR A PHASED INSTALLATION APPROACH. THE BEST COMBINATION OF VALUE AND PERFORMANCE IS THE INTENTION OF THE REPLACEMENT PROGRAM. CONTROLLERS OF THE EXISTING N-8000 SYSTEM WOULD BE REPLACED WITH THE MOST APPROPRIATE NEW CONTROLLERS. AS AN EXAMPLE, AN EXISTING "MICROZONE II" CONTROLLER WOULD BE REPLACED BY AN "MNL-800" CONTROLLER (OR EQUAL), ETCETERA. THIS WORK SHALL INCLUDE ALL NECESSARY HARDWARE AND SOFTWARE, AND A SEAMLESS TRANSITION SHALL BE ACHIEVED. FOR FURTHER DETAIL AS TO THE INTENT, REFER TO THE SEPARATE PRELIMINARY "SYSTEM ARCHITECTURE" DOCUMENTS ATTACHED THAT PROVIDE BLOCK DIAGRAMS THAT FURTHER ILLUSTRATE BOTH THE EXISTING SYSTEM AND AN AVAILABLE OPTION FOR THE NEW PROPOSED SYSTEM. IN ADDITION TO UPGRADING THE LOCAL ATC SYSTEMS, AN ENTIRE NEW DDC NETWORK WOULD BE PROVIDED. THIS NETWORK WOULD CONSIST OF MULTIPLE UPPER LEVEL, "UNIVERSAL NETWORK CONTROLLERS" ("UNCS") AS WELL AS AN "ENTERPRISE SERVER". THE ENTERPRISE SERVER WOULD CONTROL DATA TRAFFIC BETWEEN THE VARIOUS "UNCS". GRAPHICS WOULD LIKELY RESIDE IN THE UNCS FOR EACH SYSTEM. "I/A SERIES UNCS" WOULD REPLACE THE EXISTING N-8000 GCMS. NIAGARA FRAMEWORKS, OR SIMILAR, WOULD BE THE OPEN PROTOCOL SOFTWARE OPERATING SYSTEM. AT THE START OF THE DESIGN PHASE, A FIELD ENGINEERING STUDY SHALL BE CONDUCTED OF THE EXISTING EQUIPMENT. WITHIN THIS STUDY, THE MAJOR SYSTEM COMPONENTS FROM THE HEAD END, UP TO AND INCLUDING THE "SECONDARY LEVEL CONTROLLER PANELS" ("MNL LEVEL") SHALL BE REVIEWED. THIS REVIEW WILL BE NECESSARY TO ESTABLISH DETAILS OF GENERAL SCOPE OF WORK DESCRIBED HEREIN. IN PART, THIS EFFORT WOULD INCLUDE DOCUMENTING THE GENERAL CAPABILITY AN
