Vulcan Block 44

Part of Vulcan’s largest and most active project – the redevelopment of the South Lake Union neighborhood – Block 44 adds a five- and six-story office building, totaling 580,500 square feet – 375,500 square feet of which contribute to Amazon’s ongoing global headquarters expansion nicknamed Blackfoot and Nessie (Amazon Phase 6). The two buildings are connected by a glass canopy featuring a Spencer Finch art installation, which covers a public crossblock with water features, outdoor seating and landscaping. Phase VI also features 18,000 square feet of ground-level retail space.

Block 44 utilized a unique dewatering system to meet the challenge of excavation near the water table. The enterprising system not only removed water but also provided near- and long-term stability, creating a cost-effective sustainable solution for handling, disposal and recycling of water.

 

Scope Performed: This 15.6 million dollar electrical infrastructure included eight switchboards distributing 11,000 amps of 480V power throughout the building via (226) distribution panels and transformers, including (6) retail tenant services and Amazon Tenant Improvement.  Building emergency functions are backed up via a standby 350KW generator and automatic transfer switches along with a 100KW UPS system for tenant services.  For ultimate flexibility the 2.4 million dollar lighting package includes individually addressable open office lighting fixtures to allow for space specific program revisions. Base building functions are sustained with installed fire alarm, security and emergency radio antenna systems. This project also included Amazon tenant improvements.
