The Seatte Genetics project consists of a 22,410 SF Lab, 26,481 SF Office, 48,000 SF Interstitial Floor for MEP Systems and Mechanical Rooms. The construction requirements were very aggressive with a ten-month duration. At project inception, we trenched new underground plumbing utilities and installed over 100 plumbing stub ups. The GC installed a steel structure second floor and reinforcements for rooftop mechanical infrastructure and mechanical rooms. We slid into place 92,000 pounds of prefabricated ductwork, 21,000 pounds of structural support systems and our multi-trade prefabricated steel corridor rack system with mounted HVAC boxes, controls, ductwork, laboratory gas, heating, chilled water and plumbing systems. There were 19 different plumbing and hydronic piped services totaling 19,000 LF. Additionally, five laboratory gas systems were installed by pipefitters totaling 6,288 LF of pipe.
We built multiple state-of-the-art labs utilizing compressed air, vacuum, oxygen, argon, nitrogen, liquid nitrogen, RODI water, clean steam, lab hot and cold water, domestic hot and cold water, welded galvanized ductwork, welded stainless ductwork, and processed chilled water systems. Constructed in parallel with the laboratory, the offices for staff supporting the labs were built-out to the client’s high space standards. To serve hydronic systems, we temporarily routed flexible PVC piping through the trusses, and between water sources and hydronic mechanical spaces. This allowed us to fill through backflow preventers the heating hot water, chilled water and heat reclaim pump systems, and prove-out equipment point-to-point earlier than the general contractor’s project schedule indicated was even possible.
