Issaquah Middle School

The Issaquah Middle School project is a progressive design-build project. Harris’ design partner for the project was Hargis. Harris performed the complete plumbing, including domestic, DWV, acid waste, hot water plant and fixture trim. We also performed the complete HVAC, including the boiler, water to water HP, chiller and all air handling equipment. Harris’ subcontractors included HVAC controls, insulation and test and balance.

A challenge on the project was the site had a 120′ elevation change causing the foundation and structure phase to be extended longer than usual. Harris matched our labor resources to stay on schedule and to be as efficient as possible. This elevation change also presented below-grade DWV challenges. Harris’ BIM/VDC team used waterfall techniques to prove a reliable and efficient system.
