We’ve been having some fun testing large buildings! Our team has been hard at work over the past few weeks performing air leakage testing at one of Seattle’s largest high-rise projects currently under construction.

Not a bad place to spend a summer day on site. You can’t beat these views! 👌

Here’s a look at the progress on the ASUW Shell House Renovation!

Originally built in 1918, this iconic Seattle landmark is undergoing a careful renovation that balances historic preservation with modern building performance.

4EA has been a part of the pre-design team as well as the design-build team, providing services to assess the overall needs of the enclosure.

It’s been a fun project for our team, with incredible views overlooking the Lake Washington Ship Canal and Montlake Cut. We’re excited to see the project come together later this year.

At 4EA, helping create housing that serves the community is work we’re always excited to be part of! Here’s a look at Birch Grove.

This 120-unit permanent supportive housing project in Seattle’s Lake City neighborhood provides affordable studio apartments and supportive services for adults experiencing homelessness, along with commercial and office space. The wood-framed building features low-slope roofing, rainscreen cladding, vinyl windows, and storefront at the street level.

4EA provided full building enclosure consulting services from design through construction. Our scope included enclosure design drawings and detailing, construction administration support, field services during installation, window testing, and whole-building air barrier testing to evaluate enclosure performance.

Introducing Alexan Woodinville!

Alexan Woodinville is a three-building mixed-use development featuring 230 apartments, ground-floor commercial space, and two levels of below-grade parking. The project consists of wood-frame construction over a concrete podium, with a façade of stone veneer, concrete, and fiber cement. Building features include vinyl windows, storefront glazing, aluminum balconies, a landscaped podium, and primarily low-slope roofing with select metal roof areas.

4EA provided building enclosure design review services for this project, working with the design team to develop the enclosure strategy and review construction documents for alignment with project goals and current industry standards. We also provided recommendations on appropriate enclosure assemblies based on the building’s use and exposure conditions. During construction, 4EA performed field reviews to observe enclosure installation and document the quality and progress of the enclosure construction.

A new master-planned community is rising in Coquitlam, BC. The Grayson will have four six-story wood-frame buildings located across opposite sides of a city block.

The key enclosure feature we coordinated closely with Mosaic and the manufacturer on is the below-grade waterproofing system. The two-story below-grade structure is undrained and located below the water table. The cast-in-place concrete structure is being fully “bathtubbed” using both blindside and conventional waterproofing systems.

As this was Mosaic’s first time using the tanking system, the Seattle and Vancouver offices leveraged knowledge and experience across offices to help guide the process. We worked with them to evaluate different product options, outlining the advantages and disadvantages of each system before recommending a new approach.

Throughout the project, we provided ongoing support with product selection, detailing, and construction troubleshooting, helping give the team an added level of confidence and support throughout implementation.

Design is moving forward on the Vincent Apartments, with construction expected to begin this summer.

This seven-story, mixed-use development has an O-shaped layout with structured parking, townhomes, ground-floor commercial space, and apartment units organized around a central courtyard.

4EA is supporting the project with envelope design and energy code compliance modeling. We will continue our involvement through construction.

Always happy to be part of a project that adds housing and vibrancy to Northgate!

It also feels exciting and strange to be designing this project for the site of our first office space. We occupied suites on the first and fourth floors of the Northgate Office Building from 2006 until 2016.

Supporting the next phase of the Broadway Campus redevelopment, introducing a new four-story intensive behavioral health services clinic in the heart of Everett, Washington. With outpatient and inpatient components, the Marc Healing Center is built on a sloped site and has occupied decks, a low-slope roof, and European fiber cement cladding.

At 4EA, our team supported the project through construction to help deliver a high-performing enclosure aligned with the owner’s goals.

This one brought together technical know-how and thoughtful coordination. Great work, team!
