About this file
This is a mechanical design specification document for the Portland International Airport Customs and Border Protection Improvements - Phase 2 project in Oregon. The specification details instrumentation and control performance requirements for heated air curtains and variable volume air terminal units with heating coil control systems. The document, prepared by ARRIS Consulting with design oversight from Brian Butler, P.E., establishes control parameters including enable/disable functionality, fan speed monitoring, mode of operation, heating set point control, door switch interlocks, and wireless communication capabilities. The specification requires controllers to be mounted in NEMA 1 enclosures suitable for return air plenum locations and includes graphical interface requirements, alarm systems, and performance metrics for airflow, heating, and cooling operations. The design is dated September 8, 2026, and serves as sheet M5.02 of the mechanical details for the broader airport improvement project.
The specification document does not contain pricing information, set-asides, incumbent contractor details, funding sources, or contract award dates. Instead, it functions as a technical design reference document establishing the operational and performance standards for the mechanical systems to be implemented. The document includes scale references and notation requirements for proper viewing and printing of technical drawings, with specific guidance on electronic signature requirements for legal validity. This specification serves as a component of the comprehensive design documentation required for the bidding and construction phases of the Portland International Airport's customs and border protection facility improvements.
