Attachment 5 - Drawings.pdf

This document is a technical specification and engineering drawing set for the Naples Chillers Replacement project at the U.S. Embassy in Rome, Italy, issued by FAC/Engineering on May 7, 2026.

The project involves the removal and replacement of existing chiller systems at the embassy's facility located at Piazza Della Repubblica 2 in Naples. The scope includes demolition of existing condensers, refrigerant piping, chillers, and water piping systems, followed by installation of new air-cooled reversible heat pump units with associated mechanical, electrical, and building automation system modifications. Key deliverables encompass two air-cooled reversible heat pump units (HP-1 and HP-2) with 172.4 kW cooling capacity and 202.9 kW heating capacity each, dual temperature water buffer tanks (BT/1 and BT/2) with 1500-liter capacity, expansion tanks (EV-3-1 and EV-3-2) with 400-liter capacity, magnetic dirt separators, back flow preventers, and associated controls. The drawings include ground floor and roof plans showing existing versus new conditions, mechanical layouts detailing equipment positioning and piping connections, electrical modifications including new distribution panels and circuits, and detailed schedules specifying equipment parameters, pressure ratings, and installation requirements. All work must comply with manufacturers' specifications and include sealing of exterior and interior penetrations to match existing construction methods.
