Unison Elliott Bay

Unison Elliott Bay | Seattle, WA

DPR Construction is currently modernizing The RMR Group’s Unison Elliott Bay campus. Totaling 300,000 sq. ft. spread over three buildings, the campus sits along the picturesque Seattle waterfront. Partnering collaboratively with The RMR Group, Perkins & Will, and ARUP, DPR is working as a design-assist partner to convert these previously commercial office buildings into a lab-enabled campus. The project scope includes upgrading Mechanical, Electrical, and Plumbing (MEP) infrastructure, improving lobbies and common spaces, adding new amenity areas such as a fitness area and conferencing spaces, and building nearly 75,000 sq. ft. of fully finished spec suites catered to life science tenants. The project is seeking both LEED Gold and Fitwell certifications and construction is on target to be completed in Q4 2023.

RMR Unison: Building 351

Building 351 will remain a commercial office building. DPR is demolishing the interior of the first floor of this 5-story building and will leave the area in an open core and shell condition for a future tenant. The upper 4 floors will remain as-is so that they are ready to be occupied quickly with only minimal renovations. The main lobby was upgraded with finishes similar to those in Buildings 401 and 501 to create a cohesive campus feel.

Office space with many desks and individuals working from their computers.
RMR Unison: Building 401

Building 401 is a 4-story building that is receiving significant MEP, roof, and elevator enhancements to make it a building more suitable for life-science tenants. After a complete demolition back to structure on all levels, DPR will buildout the entire building as spec suite and amenity spaces. Level 2 will be built as a multi-tenant floor, each with a 60/40 lab-to-office ratio, while Levels 3 & 4 will be full-floor, single tenant suites. The total spec suite area is approximately 75,000 sq.-ft. and will include glass-walled conference rooms, gas services to lab benches, bio-safety cabinets and fume hoods, along with security and audio-visual systems.

RMR Unison: Building 501

Building 501 is a 4-story building where the core-and-shell will be upgraded to attract a future tenant who can build it out to suit their needs. DPR’s scope of work for this building, as with Building 401, includes replacing the roof, installing new primary electrical switchgear, panels, and distribution, building a new rooftop structural steel platform to support all new HVAC and plumbing equipment. Additionally, DPR is installing a new fire sprinkler system with increased density to support future lab work, enlarging shaft openings in an existing post-tensioned slab to enable increased air supply and exhaust ventilation, and enhancing the security and life-safety systems.

Multiple lab stations with workers engaging in conversations.
