1001 Office Towers
These twin Class A high-rise office towers located in downtown Bellevue are custom built for the tenant and are pursuing LEED Gold Certification. They boast an elegant-yet-efficient design.
This project is a great example of a high-rise office complex moving away from an all-glass facade. The incorporated opaque wall elements with faceted metal panels and precast concrete allow for greater levels of insulation and thermal efficiency. Rather than adding scaffolding or hanging steel stud framing, the facades use these large format precast concrete as well as faceted metal panels mounted to an insulated curtain wall chassis as a back-up wall as a means of installing with limited need for access to the building exterior. The panelizing of the facade systems helps Simplify It and provide for seamless installation and a fast construction schedule.
The incorporation of open-air balconies into a steel-framed commercial high-rise building is a unique feature that required careful coordination and attention to detail, especially since the project is pursuing a high level of airtightness.
As the enclosure consultant and Building Enclosure Commissioning Agent (BECx), 4EA worked closely with the architect and project stakeholders on the design, testing, fabrication, and installation of the facade and overall enclosure. This included custom laboratory performance mock-ups, quality assurance visits to the curtain wall plants, and on-site review and performance testing. These checks help deliver confidence that the enclosure is well constructed and performs as intended.
