1) Background

a) This Scope of Work (SOW) is for the VAFO Administration Building located at 1400 N Outer Line Drive, King of Prussia, PA 19406.

b) The administration building was constructed in the late 1960s and has been operating with the original HVAC equipment until a project was completed in 2019 to upgrade the HVAC equipment.

This project only included cleaning of the 5 heating coils. In October of 2021 one of the heating coils was faulting and problems were found with the internal wiring. This unit has been disconnected and is currently not in operation. Another heating coil, the largest of the 5, is functioning on only 2 of the 3 coils. All 5 units to be replaced are past their expected serviceable life and are in need of replacement.

c) The project includes design and replacement of five (5) in-duct heating coils and associated components to include, but not limited to, contactors, transformers, and fuse boxes. Additionally, the new HVAC system is controlled by a Building Automation System (BAS) and the awarded contractor shall be responsible for ensuring proper communication and operation between the new heating coils and the existing BAS system.
