INSTRUCTORS: Jeff Becksfort and Ned Greene
This course is part of a three part PDXNext webinar series. You may take this session on its own or explore all three courses in the series.
Purpose and Background
This session examines the mechanical systems transformation that underpins the sustainability and resilience goals of the PDXNext redevelopment. With the airport remaining fully operational throughout construction, the design and construction teams implemented a phased strategy to replace aging steam systems, introduce low temperature hot water distribution, integrate a ground source heat pump system, and condition large architectural volumes. The session highlights engineering innovation, logistical coordination, and lessons learned from executing complex mechanical upgrades in an active airport environment.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Explain the engineering and logistical considerations of phased infrastructure conversion in an active airport.
- Explain how hydrogeological analysis supported the installation of a resilient, all electric hydronic heating and cooling system.
- Describe how mechanical systems were integrated with architectural design to maintain comfort, pressurization, and performance.
- Recognize how collaboration among design teams and trade partners enabled constructability and operational continuity.
Assessment of Learning Outcomes
Students' achievement of the learning outcomes will be assessed via a short post-test exam involving true-false and multiple-choice questions.
Who Should Attend?
- Mechanical engineers and system designers
- Construction managers and trade partners
- Airport facility and operations staff
- Architects and integrated design teams
- Sustainability and resilience specialists
- Owners and program managers overseeing phased renovations

How to Earn your CEUs/PDHs
Upon completion of this course, attendees will receive .1 CEU/1 PDH. To receive your certificate of completion, you will need to complete a short post-test and receive a passing score of 70% or higher within 30 days of the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
