Seattle Municipal Tower Tenant Improvements & Minor Renovations

Greenbusch (as a subconsultant) has provided mechanical and acoustical design services for numerous tenant improvement projects in the Seattle Municipal Tower for several years. The 57-story, City of Seattle owned building houses many City departments including Seattle Public Utilities (SPU), Department of Finance and Administrative Services, and Department of Construction and Inspections (SDCI), as examples.

To meet contemporary programmatic needs, Floor 53 occupied by SPU, and Floors 20 and 21, occupied by the SDCI (Seattle's permitting authority), were transformed from a series of small offices and a closed space, into an open office concept. The modernized, expansive, work environment envisions easier communication between staff, improved work flow, and allows for a larger occupancy within the existing footprint. Designing for added staff and accommodating occupant comfort required increased air flow and new layouts for mechanical systems. Greenbusch designed the layout for new HVAC equipment, ductwork, plumbing, and fire protection systems, and coordinated the relocation of existing equipment and ductwork, for the new arrangement of spaces. The firm authored specifications and provided construction support services.
