Architectural Excellence : Portland International Airport embarked on a five-year remodel and needed temporary office space to relocate airline employees displaced for the project's duration. With a total lack of space, the challenge was to be creative with where this temporary office space could be housed without moving it off the property.
The airport found space under the departure ramp and between its large supporting pillars. The height, width, and configuration of any buildings would need to be carefully considered. Traditional stick-built buildings would be costly and nearly impossible to complete in their time frame of nine months or less. The airport's general contractor, Hoffman Skanska, turned to modular construction to get the job done.
Pacific Mobile provided six buildings, including a 30X40, 40X88, 40X40, two 20X40 office buildings, and a 50X40 combined office building with restrooms and janitorial rooms. Ninety-six lineal feet of deck and ramps connect the buildings.
Cost Energy Effectiveness : A traditional stick-built structure would have been nearly impossible to build with the site’s constraints while costing millions of dollars for a building they only intended to use for five years and then remove. It also would have been extremely costly to rip up the existing concrete to create an entire foundation and implement extensive foundation support needed due to the site constraints and the rerouting of data electricity, security, and more. Not to mention, it would have been impossible to meet their time constraints of six months to a year for this project with a traditional stick-built structure. In return, going modular allowed the airport to have the structures they needed on-site six months to a year earlier than traditional methods would have allowed while saving a considerable amount of money. They decided to purchase the buildings rather than rent, so they have the option to relocate the buildings for any additional needs for space in the future.

Green Building Description : The buildings utilized 27 Daikin Mini Split multi-zone HVAC systems with higher quality air filtration to reduce the spread of COVID-19 and minimize poor air quality due to the emissions from jets and cars in the area. A hospital-preferred choice, Merv 16 system featuring double filters, was utilized to achieve higher quality air filtration. Merv 16 systems last much longer, accompanied by a Merv 8 pre-filter.
The carpet squares installed in the buildings came from the airport's overstock leftover from previous remodels. The carpet was repurposed to save the airport money and lower the project's environmental impact. In addition, all light switches were installed with timers lending to energy conservation. With the buildings equipped with sufficient light fixtures, an abundance of windows were installed to further combat low light levels due to their placement under a parking ramp.

Technical Innovation : Due to the site constraints, all the buildings could only measure 40 feet or less in length and had to be placed directly on the ground, foregoing a crawl space beneath them to adhere to the height restrictions. The plumbing needed to be placed in a dedicated plumbing room rather than underneath the building and installed on-site, along with wall split HVAC systems. EZ Systems explicitly designed a unique caster-based rolling system for this project that allowed the buildings to be maneuvered on the ground with speed and ease. When on-site, EZ Systems unloaded each of the buildings onto cribbing and then dropped them down to the ground on top of the rollers positioned in all four corners. Forklifts held steady on either side of each of the buildings to ensure stability as they were rolled under the pass. Then, the crew manually pushed and maneuvered each of the buildings into place and bolted them to the in-ground concrete footings for support and stabilization.
