Microsoft Building 43 WPA

185,000 sf | Redmond, Washington | Campus | Design-Build Engineering

Hermanson worked with Inventrix (now Stantec) to design and install a new VSVAV system in a 185,000+ sf office space. Utilizing multiple air handlers sharing a common medium pressure loop, the 436 VSVAV installation enabled multiple levels of redundancy as well as enabling greater overall system efficiency.

This project also facilitated the migration of multiple active labs throughout the building to a single lab on the first floor. The new lab utilized 36 chilled water CRAC units for cooling alongside the reuse of a dedicated AHU for fresh air and maximum economized cooling. The lab migrations took place during active demolition and construction and were completed successfully with zero unscheduled downtime, which is a testament to the careful coordination, tracing, and identification of all systems prior to the start of demolition.

Having recently completed similar projects on the Microsoft Campus, the project team brought a fresh perspective to the table. Issues such as the age-related failure of existing fire smoke actuators were able to be identified and replaced prior to total failure. This ‘best practices’ approach allowed the project team to avoid a costly retrofit at the end of the project by taking advantage of the demolition activities and identifying partial actuator failures early.

The project team also utilized a refined work flow schedule that broke the floors down into color coordinated zones. This allowed for equipment and ductwork to be spooled ahead off-site and delivered just in time for the next shift’s installation. This eliminated the stocking of material for later installation, decreased overall lay down space, created a safer working environment, and allowed the project to increase manpower by 50+ workers in a single day while maintaining high levels of productivity. Overall, the zone method has become an established best practice necessary to achieve the challenging timelines required when working with a high tech client.
